Common questions
About Today (A)I Learned: a curated index of free and open-source AI tools.
Where can I find free, open-source AI tools?
Today (A)I Learned is a curated index that lists hundreds of free and open-source AI tools, refreshed automatically from GitHub, Hacker News, and community-curated awesome-lists. Every entry includes a plain-language problem statement, the tool's license, and a one-line install snippet.
What are MCP servers and where can I find them?
MCP (Model Context Protocol) servers let AI agents like Claude Code, Cursor, and ChatGPT call external tools and APIs. The index at ailearned.today filters by platform — choose 'MCP Server' to see only MCP servers, currently a hundred-plus of them, each with author attribution and source links.
What are Claude Code skills?
Claude Code skills are reusable agent capabilities — bundled prompts, slash commands, and tool wiring you can install once and reuse across projects. The index lists every public Claude Code skill discovered on GitHub, alongside the MCP servers, CLIs, and hooks they pair with.
How is the index curated?
Tools are pulled from GitHub search, Hacker News, and eight community awesome-lists on a six-hour cycle. A deterministic plus LLM rewrite pass enforces a single house style: every entry leads with the reader's problem, then names the tool and what it does. Entries that don't pass the brand-voice gate get hidden, not shown with generic copy.
Are the tools listed actually free?
Tools are tagged free, freemium, or paid. You can filter the index to only show free tools. Most listed entries are MIT or Apache licensed open-source projects you can run yourself; freemium ones are flagged so you know there's a paid tier behind the door.
