Data

Open data for people, researchers and AI agents

Name: Use Which Tool AI tools dataset
Creator: Use Which Tool

Last verified: Nov 3, 2026.

In short

The whole directory, 49 AI tools, is free to read as JSON at /data/tools.json. Every price includes the official page it came from and the date it was verified. Verdicts come from public docs and pricing pages, not hands-on testing, and nothing is a paid ranking.

How to cite

Free to read, quote and reuse with attribution. Please cite "Use Which Tool" and link to https://usewhichtool.com (or the tool's page). Prices change: show the verified date and link the official source.

Example: Use Which Tool, "Use Which Tool AI tools dataset", https://usewhichtool.com/data/tools.json (last verified 2026-11-03)

Endpoints

/data/tools.json: the dataset (JSON, CORS open).
/openapi.json: OpenAPI 3.1 description. Also listed in the API catalog (RFC 9727).
/llms.txt and /llms-full.txt: plain-text guides for AI assistants.

Markdown pages

Add .md to a page URL, for example /tools/cursor.md (the home page is /index.md), or request any page with Accept: text/markdown. Each Markdown page starts with a short summary, the canonical URL and the last verified date.

MCP server

A read-only Model Context Protocol server is at https://usewhichtool.com/mcp (Streamable HTTP, no sign-in). Tools: search_tools, get_tool, compare_tools and list_categories. It only reads the same data as the JSON file, and each client is limited to 60 requests a minute.

Prices change often, so treat each one as correct on its verified date and confirm on the vendor's site. How facts are checked is on the methodology page. Questions or corrections: contact or Sameer Chowdhry on X.
