The Practice Innovations department handles setup and manages all ongoing Kira projects. We currently use Kira to speed up high-volume contract reviews for clients and to organize our outside counsel policies.
  • UI/UX - tagging and naming feels much easier than you'd expect machine learning to feel
  • Accuracy - Kira's built-in models perform well out of the box
  • Assistance - Kira's support team gets back to me same day if I have a question
  • Missing functionality - rules; regex; that's the next step in our workflow we'd like to automate
  • Quick Study - I'd prefer a quick study window that I could personalize more. Alphabetical foldering means I usually have to search for my clauses because it's too hard to find them when scrolling. There are too many clauses in Quick Study that we've never used and can't edit. Why not have a separate built-in clause bank?
  • Renaming documents - people upload them with crazy names. I'd rather be able to change the name than have to determine whether it's worth the cost to re-upload the same document with a helpful name.
Kira is great for extracting text from a document. It doesn't have legal judgment. It doesn't understand whether a clause should be in a contract, but it can tell you if it's there or not.

It is almost exclusively used as a due diligence tool at my firm. The main users are trainees, junior associates and our ALT teams in Belfast and Australia. As far as I'm aware, it is mainly used for M&A transactions.
  • Automated review of documents which are in a similar form.
  • Use of smart fields/filters.
  • Customisation.
  • Integration with other providers.
  • Desktop launch.
Kira is a great due diligence tool and can be well utilised on both large and small transactions. It also has good application if you are looking to compare multiple documents against a model form document or market standard templates. Kira is less useful if you are looking to review emails (e.g. as part of a disclosure exercise); or if your review involves non-Latin based script languages.

Kira is used across our international business by any practice group that needs to undertake document review and due diligence. We use Kira to improve the quality and efficiency of our document review process.
  • Good for quickly getting to the relevant part of the document in the English language, the smartfields are accurate.
  • Handles large scale review well with an excellent UI and helpful project management features.
  • Cloud-based platform handles multiple simultaneous reviewers efficiently and easily.
  • Ability to self-train smart fields is a definite advantage.
  • Inability to relabel smart fields to suit the review process means it is hard to align it to particular projects (e.g. it would be useful to relabel the "Assignment" smart field as "Is the contract assignable?")
  • Not enough non-English smart fields.
  • Needs the ability to resell user-trained smart fields in a marketplace.
  • Output is not customizable enough.
  • Built-in analysis tools are useful but a little basic.
Kira is particularly useful in large scale review exercises with multiple reviewers across different departments. Its benefits scale with volume.

We are a Brazilian law firm. As such, Kira is not able to be used in the majority of our work out-of-the-box. In addition to training Kira to handle Portuguese documents, we are already using Kira in M&A Transactions and to read and extract certain information from legal certificates (in both cases limited use only).
  • Reading M&A Contracts
  • User-friendly interface
  • Simple training process
  • Develop other languages out-of-the-box
  • Customize options to extract information
  • More interactions with VDR providers with need to download documents
Being a non-English-speaking user, although Kira is a very useful tool and has great potential, having to invest many hours in training before being able to effectively use the software in real-life application is by far the greatest drawback. If that initial barrier is surpassed, Kira is very useful for any contract-based law practice. It is not very useful for Brazilian litigation standards.

Review various types of contracts with specific provisions of accounting significance. We use it as a quality control check to make sure we didn't miss anything when we read the agreement. It is being used by both our assurance/audit practice as well as our tax practice and risk advisory practice.
  • Good agreements already trained by Kira.
  • Reviewing documents in Kira with color coding.
  • Export to Excel/Word.
  • Ability to customize access and structure at organization level/restrict which models can be used.
  • More detailed user guides.
  • More models trained by Kira for accountants.
Kira is well suited for reviewing long agreements that are fairly standard. There is a risk that something can be missed when manually reading, and this risk increases as the length of the agreement increases.

My review of Kira

Complete an initial review of standard contracts for certain important terms of the contract, and to extract those terms into a visually appealing document.
  • It does what you tell it to do. By that I mean you have to train it to find relevant passages in a contract. Once you do that, it does it well, but that process requires a lot of time to train and many examples.
  • It does it over and over again: Once trained, it can repeat the process ad infinitum.
  • It can learn: When you review a document and realize it either highlighted something it shouldn't have or didn't highlight something it should have found, you can alert Kira to that correction and it learns from that information.
  • Finding that many contracts aren't that 'standard' and if not standard, it is impossible to find enough examples to train with
  • Many contracts have handwritten data, especially the key terms that it cannot read.
  • Sometimes the contracts have attachments with important terms, we find that harder to train.
Great: Standardized machine legible contract reading and extraction. Not so great: non-standardized terminology or illegible or handwritten documents.

Our firm has used Kira so far mostly for training it to read contracts in Portuguese. We have achieved good accuracy in some clauses so far and have used the software in a few due diligences for M&A transactions. Kira was used only in controlled scenarios and by people that are part of our project on implementation.
  • Good out of the box clauses in english with great accuracy.
  • Good costumer services, always with fast and efficient responses.
  • Easy to use, not requiring much training for using.
  • Kira doesn't have out of the box clauses in other languages.
  • High prices, especially considering the market in Latin America.
  • Capacity of reading other types of documents, such as certificates.
Well suited for law firms focused on M&A in North America, Canada, or the UK. For firms outside English speaking countries, I believe Kira can be too expensive to be used, once it requires that the firm itself teaches Kira how to read in their language. In our experience, once Kira is ready to go it can be an extremely important and useful asset. However, it takes a lot of time to get it ready to go. And it can make Kira very expensive in countries where English is not the primary language.

We use it broadly across the whole organisation, however some teams use more than others (Commercial and Real Estate). We use it for business as usual document reviews, as well as some larger projects focussed around diligence exercises and/or contract reviews. It solves the problem of inefficient doc review tools / manual processes being carried out by junior members of the firm. Speeds teams up a lot on that first level of review.
  • UX - very easy to use and train people on.
  • OCR and doc search is well organised and functional.
  • Comparison feature really good.
  • Project management features make review teams easier to manage.
  • Built in provisions really useful for standard documents.
  • Training new provisions can sometimes be a bit unwieldy.
  • Search across all documents sometimes too over inclusive (in documents it is great).
  • Inability to rename folders and files in the platform.
Well suited - standard reviews of similar document sets. BAU work where similar documents are repeatedly reviewed. Any large scale review really, just as long as it is managed properly and the limitations are explained.
Less appropriate - Looking for nuanced or complex information that patterns are less likely to be found in. Like doing a general provision for 'Restrictions.'

By a number of departments, but not all. To speed up due diligence carried out by lawyers and to improve accuracy and project management.
  • Intuitive system: easy for users to pick up.
  • Constantly improving product with regular publication of new pre-trained fields.
  • Excellent training videos and online help available, plus a knowledgeable help desk.
  • Strong account management with account managers who really do know the product and their customers.
  • Extension of the tool so that it is not just extraction of clauses, for example, some products can re-draft contracts once areas for change have been identified.
  • Direct link with iManage.
  • Ability to change name of document once uploaded, which is not currently possible.
  • Ability to change the name of pre-trained fields to better match client requirements.
  • Extension of the tool so that if a certain clause is found a pre-written shorter summary is inputted.
Best used for more standardized documents. It can sometimes struggle to read poorly drafted documents because of a lack of pattern in them.

It is being used by attorneys in our transactional practices on select projects. It helps organize incoming workflow and enables us to manage tasks by spreading the work across multiple resources. Additionally, it streamlines the process of document review by automatically detecting provisions. It reduces the time typically used to do the same tasks manually.
  • Automatic detection of provisions
  • Ability to assign tasks to multiple resources
  • Easy to use interface
  • Significantly lacking different levels of permissions for user accounts
  • Significantly lacking alerting and notification mechanism
  • It is not competitively priced in comparison to other platforms that offer the same technology
Kira Systems is suited for projects that:
Require quick turnaround
When the typical size is 50 to 500 documents
Where the typical scope is focused on generic provisions

ENSafrica uses Kira Systems for our contract and document review projects in order to improve efficiency, speed, and accuracy. Kira is also used to reduce risk and costs in regard to our contract and document review. Kira is open for usage to our entire organization. Kira is mostly used by our Corporate Commercial departments regarding, inter alia, due diligence investigations.
  • Kira quickly identifies, analyzes, compares, and extracts text in contracts and other documents.
  • Kira has project management features.
  • Kira has hyperlink features.
  • Kira has exporting features.
  • Not having the ability to analyze handwritten or less legible content.
  • Kira should bestow clauses that cover jurisdictions globally.
  • The structure of Kira could improve. For example Worksheets could follow Document List.
Kira systems is well suited for the review of contracts and documents relating to due diligence, compliance, labor law matters, lease abstraction, finance and project management, amongst others. Kira is also well suited for comparisons of contracts and documents, a tool our Firm has also utilized. Furthermore, Kira is well suited for exports and project management. Kira is less appropriate for languages such as Mandarin or Arabic. Kira is also less appropriate when dealing with contracts or documents containing less legible content. Though our Firm has not requested training (quick study), the element of training Kira and the pursuit of documents in order to train Kira can also be seen as a hurdle.

We are evaluating Kira to help us with due diligence, data capture and other more mundane tasks that can be routinized.
  • Easy to use
  • Flags items that attorneys may miss.
  • Great for project management of a deal.
  • I think the training process could be better.
  • Cannot bulk highlight, say where you've already tagged something and want to re-use.
Helpful for diligence review and especially so when language is the same or similar for a particular concept.

  • Used to improve the way we carry out transactional document review exercises, enabling us to more effectively and efficiently carry out those exercises, and at a greater scale than would otherwise be possible.
  • Used across our international practice.
  • Heavy use in our low-cost paralegal team—Legal Delivery Centre.
  • Quickly surfacing unstructured data from large sets of documents.
  • Assisting with the workflow aspects of a doc review exercise.
  • Expanding the set of built-in smart fields to cover non-English languages.
  • A wider range of integrations with other tools. Existing integrations to be more fully-featured and customizable.
  • Ability to record and surface structured data from documents.
  • More customization of format of exported output.
  • Comprehension of "families" of documents (eg. a primary document and subsequent variation/amendment documents). Kira currently treats documents on a doc by doc basis.
  • Well suited to attempts to "map the landscape" and get a high-level view of a large set of diverse documents in a transactional due diligence context.
  • Less suited to attempts to extract and collate structured data from a set of similar documents.

We are currently using it for due diligence exercises across the firm. It allows us to speed up the review, and assists with the accuracy of our review. We also use it for internal validation exercises and determine trends in the market. Finally, we use it to help search across certain decisions from quasi-judicial bodies to determine trends in decision making.
  • User friendly
  • High degree of accuracy
  • Easy to manage projects
  • Excellent search capabilities
  • More options for exporting results.
  • Integration with document automation platforms.
  • Separate client only view.
Red flag DD reporting is an obvious example of where Kira works well. You require a defined set of red flags, and reviewers must be comfortable differentiating between true red flags and ambers based on Kira results, but this process can be effectively streamlined and lends itself well to the out of the box trained Kira concepts. Kira is less helpful in niche, practice/market specific scenarios, where out of the box concepts do not exist and training is required. While the training can be performed, it doesn’t allow for the practice to immediately avail of Kira’s best quality.

We have used Kira System to assist with the first review of large data-sets in the context of transactions.
To date, 3 of our practice groups have used the tool—our Corporate, Property, and Employment teams.
Being a mid-sized firm we don't have teams of people to review large-ish document sets. Even if we did, clients don't have the appetite to pay for teams of people to identify and extract key terms. The value is not in identification and extraction but rather in the legal team's review of those terms. Using Kira assists us in meeting the expectation of our clients. They appreciate that we form strategic partnerships with others, such as providers of legal tech to help provide the best legal service and keep the costs down. Using Kira to identify and extract key terms means that our legal teams can focus on the analysis and are often earlier on in the process due to Kira's ability to undertake this task very quickly irrespective of it being a large and often unstructured data-set.
  • Review of large unstructured document sets very quickly. Often the identification and extraction of identified key terms can happen in a few minutes.
  • Many pre-build key terms particularly for mergers and acquisitions.
  • Training Kira to recognize locally used terms and concepts is easy to do.
  • Some project management functionality i.e. the ability to set up project groups and assign tasks to members in the project team.
  • More assistance with the building of locally used terms and clauses particularly for smaller firms who don't have the people to sit and train.
  • Nicer looking standard templates.
KIRA is well placed to assist with the review of large sets of documents quickly. Particularly terms that are used and recognized in a number of jurisdictions (USA/Australia/UK), assignment, and change in control. Review documents where terms to review are very specific to the jurisdiction outside the USA, for example, property terms in Australia.

We use Kira as a core tool in our offering to clients for reviewing contracts and documents at volume. It makes us more efficient and greater capacity. The tool is very reliable and is capable of being trained and adapted to ours and our client needs. Support and customer service from Kira has always been very strong.
  • Stable.
  • Easy to train.
  • Easy to use.
  • Would be great to be able to have a market for trained fields.
Kira is very strong in the English language and works very well for all Latin script languages. Uploading documents is easy and the project management tool enables us to manage large scale reviews efficiently. We have used this for due diligence exercises and for large scale regulatory reviews. Whilst the core tool is suited to Latin script - the compare function works really well in any language.

We use Kira to verify contract information during audit, tax, and consulting engagements. It helps us identify issues earlier in the process, standardizes our procedures, and saves a bit of time.
  • Kira allows us to create standard procedures for what we look for in a particular type of contract.
  • Kira can highlight the top things we want to pull out of a contract.
  • Allows us to complete the review process in one place, then export the information to our work papers.
  • Makes us feel good about using AI.
  • The interface is built for a customized experience every time you use Kira. We like to standardize. Audiencing the experience will help us a great deal.
  • The ability to integrate with more systems to export the data directly into.
  • Analyzing the table data.
  • Provide additional organizational management features—like default worksheets that stay, the ability to order the worksheets and deletion of users, contracts, and projects.
It works well on standard contracts and allows us to push the work to less experienced staff members.

We use Kira for M&A diligence. We represent an organization that does 10-20 purchases per year, and therefore we have a lot of legal contracts we review. Kira pulls all the terms that we are concerned about as part of an acquisition and cuts down time that our legal team would have to spend searching through and reading all contracts.
  • Pulls specific terms from a contract
  • Search terms in a typically "unsearchable" (scanned) PDF
  • Control what terms exactly you are looking for
  • Training process for new terms is complicated
Kira Systems is perfect for searching for specific terms within a large number of contracts. It can pull as many terms as you need. Great for if you are searching for a specific term across a multitude of contracts--can then pull down the report and quickly identify which contracts have such terms and easily create a report of issues within terms.

Specific teams of lawyers use it for specific deals. My team uses it to train on specific provisions or run specific projects on behalf of clients or to support lawyers. It is used to help run due diligence projects more efficiently. It enables junior lawyers to manage the delegation and completion of a number of tasks within a due diligence/contract review. It allows lawyers to copy and paste provisions into Word quicker by automating parts of the process.
  • The dashboard screens allow lawyers to easily add and manage tagging of provisions in one place.
  • The UI allows lawyers to manage a large number of agreements at once and jump between the identified provisions and the underlying document.
  • The analysis charts allow for a more high-level overview of the grouping of documents allowing lawyers to drill down to specific provisions really quickly.
  • The already trained provisions need improving - we find a lot of them need retraining on our documents to be helpful. Too many false positives still.
  • Being able to ignore some provisions from the review - particularly where Kira is bad about identifying them.
  • Being able to share some of the outputs with clients (especially on the comparisons side). The heatmaps are great but being unable to share them make them less useful to internal teams.
  • The integration with HighQ needs some work to make it more useful for the kinds of client interactions needed.
  • The Pricing Model needs to be much more flexible and reflect the different ways that the tool is being used at organisations.
  • Client service, account management and communication need improvement.
I recommend internally only. Externally the pricing model makes it less attractive to a lot of my colleagues. And there are alternatives that should be investigated (and comparing). The Canadian advantage was lost once the algorithms stopped being trained on Canadian agreements (UK and US are not the same).

Kira is used in various departments in our organization. For the first few years, the primary use of Kira was for M&A Due Diligence. For the past couple of years, we've been exploring more uses, for example, contract analysis, contract management, and deal studies. The recent "shelter in place" world that we live in has expanded our user's acceptance of Kira.
  • Our lawyers love using Kira in straight-forward due diligence projects.
  • Recently, more specialists have become interested in using due diligence for their reviews.
  • Kira handles the project management very well.
  • Working with data rooms (importing updates to the data room) is our users #1 complaint.
  • Reporting: It's pretty basic, better graphical interpretation of the results would be helpful.
  • Identification of similar documents: I know they're working on it but it would be a good feature to have.
Kira is well suited to handle standard M&A due diligence and contract analysis. We're just beginning to explore it to do deal studies and contract management but feel there's a lot of potential to use it for those. We're also exploring ways to use it to enhance our knowledge sharing libraries.
