What is aiknow?
aiknow is an AI tool directory that lets you find software by describing what you want to do in plain language instead of scrolling rankings or comparing specs. It catalogs more than 4,800 AI websites and projects and updates the listing daily, and it organizes them into ten-plus categories such as Agent & Automation, AI Creation, AI Office, and AI Coding. The search is conversational — you type a need and it surfaces matching tools — and results can be narrowed with practical filters including free, open source, API available, self-deployable, and MCP support, which makes it useful for developers screening tools on real integration criteria. Alongside search it maintains curated "popular" and trending lists and hand-picked recommendations across assistants, models, agents, and open-source projects. The whole service is free with no registration required, which lowers the barrier to quick discovery. For readers on BestAIFor comparing directories, the distinguishing points are the natural-language query model and the developer-grade filters (self-deployable, MCP support) rather than breadth alone. The main trade-off is that aiknow leans toward Chinese-language content and includes a "domestic" filter, so coverage is weighted toward that market.
