Grok Thyself (grokthyself.com) is a tool developed by Jan_Wilmake and launched on April 7, 2026. It synchronises a user's X (Twitter) posts, bookmarks, and likes into a private GitHub repository of the user's choice, creating a structured, AI-queryable personal knowledge base from social media activity.
The tool was inspired by Andrej Karpathy's viral thread on LLM knowledge bases (April 5, 2026), in which Karpathy advocated for using LLMs to build and maintain personal knowledge bases. Jan had been building personal knowledge infrastructure since 2024, and Karpathy's post provided the catalyst to productise the X-data sync component.
Jan's initial question to his audience: "who wants a continuous sync of all their tweets+bookmarks+likes into a private github repo to augment their knowledge base?" — received strong interest.
Within 24 hours of launch, Grok Thyself achieved:
| Metric | Count |
|---|---|
| Likes on launch tweet | 185 |
| Bookmarks | 290 |
| Sign-ups | 40 |
| Paid subscribers | 3 |
Jan described the launch as "a success" and immediately pivoted to the next product in the pipeline: Self-Driving_Repos.
An unexpected development: someone in the web3 community created a memecoin for Grok Thyself through a decentralised crowdfunding mechanism, motivated by a desire to support solo developers. Jan had no involvement in or awareness of this until notified by a user.
Grok Thyself is the data ingestion layer for Jan's broader personal knowledge base architecture:
