listai.tools: AI tools filed by what they make
listai.tools is a free directory of AI tools, sorted by what each tool actually makes rather than by who it is marketed to. Six verticals cover writing, image, video, audio, coding and AI agents, and 82 categories go one level deeper. Every submission is reviewed by hand and keeps a permanent page. Listings are ranked by upvotes, and the whole catalogue can be read by AI agents over MCP without an API key. Pricing: freemium.
