Fiuto

Fiuto is a user research tool that runs the full research loop. It drafts a study around a product and its audience from a URL or a description, runs it with AI testers first and then with real people recruited from Prolific's panel of 300,000+ participants or the team's own users, and turns the results into findings, a readout, and a shareable deck.

Eighteen research methods, including five-second tests, first-click tests, card sorts, tree tests, preference tests, surveys, and live-site tasks, are available on every plan, including the free tier. Studies can be created and read back from the web app or over an MCP server, letting coding agents such as Claude Code, Cursor, Codex, Lovable, v0, Replit, and Bolt draft and launch a study without leaving the editor.

Results export as CSV or JSON through a per-study API token. Pricing is per account with unlimited viewers and unlimited editors on paid plans; there are no per-seat charges. The product is built and maintained by a UX researcher with over a decade of experience running studies for other companies before building this one.
