About Xbrain

X Brain is an AI search and knowledge base for the tweets you have liked on X. The site says the X app stops loading very old likes, so X Brain imports your full data archive instead. You request the archive from X settings, which can take up to 24 hours, upload the ZIP, and every liked tweet becomes searchable by meaning through vector embeddings rather than exact words.

Tweets are automatically classified into 15 categories and more than 65 subcategories, and key takeaways, tools and references are extracted from each. A knowledge stats view shows what you have been learning over time. Results can be exported to an Obsidian vault with frontmatter, tags and index files, or to Markdown, CSV and JSON, and a built-in MCP server lets you ask Claude about your own saved posts. AI processing is included with no API key needed, though you can supply your own key from Anthropic, OpenAI or Gemini. It is a one-time $4.99 payment with no subscription and a 30-day money-back guarantee.
