The Free Claude Tool That Writes Your Own Personal Wikipedia
An open-source build of Andrej Karpathy's LLM Wiki idea: drop in your PDFs, notes and docs, and Claude writes a cross-linked wiki with citations back to your files, then keeps it updated every night
Most of what you save, you never find again: PDFs in Downloads, notes in five apps, articles you meant to reread. Andrej Karpathy, an OpenAI co-founder, proposed a fix: let an AI read everything and write you a personal wiki it maintains itself, instead of searching from scratch every time you ask. This free, open-source tool builds exactly that on top of Claude.
Here's what it does, how to set it up, and the catch.
What it does for you
- Reads your files: PDFs, Markdown and text notes, Word, PowerPoint, Excel, web pages and images.
- Writes a page for every topic, cross-linked like Wikipedia, so related ideas from different files end up side by side.
- Cites everything: each page carries footnote citations back to the exact source file.
- Shows the shape of what you know in a graph view of how your pages connect.
- Keeps itself tidy: a lint pass flags broken links, orphan pages and stale pages.
- Updates on its own: a nightly Claude routine folds in new files while you sleep.
- Clips as you read: a Chrome extension saves web pages and PDFs with your highlights, and Claude sees those too.
