## About Humans to Know

Humans to Know is a web directory of reusable AI agent skills. A skill packages instructions, sometimes with scripts, references or templates, for a repeatable task such as reviewing code, planning research or writing a product brief. You can browse published skills, read their instructions and follow links to the original source.

Each skill is listed with the people and teams who publish it, and their profiles show how many skills they have shared. The site ranks humans by published skill count, which is a catalog measure rather than a measure of quality. Makers can publish a skill by sharing their instructions and source.

Rights stay with the original authors, and each source license sets how a skill can be used. Agents can read public skill pages through llms.txt or connect through MCP. Finding a skill does not install or run it, so users should test it on a small task first.

## About Notelify

Notelify is an AI study workspace that turns study material into notes, flashcards, quizzes and mind maps. You can paste a YouTube link, upload a PDF, slides or a textbook chapter, or add audio, and the workspace produces a summary with structured notes and study assets in about a minute. Each output is built from your own source rather than a generic template, and timestamps link back to the video for YouTube lectures.

The workspace also includes an AI tutor that answers questions grounded in the sources you uploaded, a transcription feature that converts lectures and podcasts into searchable text, and PDF export with a reusable notes library. Higher plans add audio, video, image and PowerPoint uploads, advanced study tools and an exam prep pack.

Notelify is aimed at students revising lectures, textbooks and slides for exams, and at researchers and professionals who need the main points from papers, reports or recorded talks without rewatching or rereading everything.
