What is Thinkfree Office?

Thinkfree Office is an on-premise and private cloud office suite that enables organizations to create, edit, share, and collaborate on documents while maintaining control over data. Designed for enterprises, SaaS providers, cloud service providers, and software vendors, the platform combines online document editing, real-time collaboration, and flexible deployment options.

Thinkfree AI Office extends these capabilities by integrating AI-enabled document workflows directly into the editing experience. Organizations can deploy a secure private AI environment using Public, Private, or Self-hosted Large Language Models (LLMs), facilitating AI-assisted productivity without exposing sensitive information to external services.

Unlike cloud-only productivity platforms, Thinkfree supports on-premise deployment, private cloud deployment, and API-based integration, catering to organizations that require data sovereignty, regulatory compliance, and full ownership of infrastructure.
