As answered by people managing XBrain.live and cppq.
XBrain.live's answer
Early-stage - not yet at a scale to name individual customers
XBrain.live's answer
People who use X/Twitter likes as a personal read-later or knowledge-capture system - the PKM and Zettelkasten/Obsidian crowd, founders and indie hackers who save build-in-public advice, and anyone with a large liked-tweets archive who's given up trying to find anything in it again.
XBrain.live's answer
X Brain is likes-first, not bookmarks-first - X's API doesn't expose bookmarks to third parties, so most competitors build fragile browser extensions around bookmarks while your years of liked tweets sit permanently inaccessible past X's ~3,200-item archive limit. X Brain works from your official X data archive instead: upload once, and every liked tweet gets embedded, classified into 15 categories and 65+ subcategories, and enriched with an AI-extracted key takeaway. It's a one-time $4.99 payment, not a subscription, your own AI provider key is optional, and it exports natively to Obsidian and connects to Claude via MCP so you can search your likes mid-conversation.
XBrain.live's answer
Most rivals (Dewey, Tweetsmash, ContextBolt) are subscription-priced and bookmark-first, relying on live browser extensions that break when X changes its UI. X Brain is a one-time $4.99 payment, focuses on likes (an archive format competitors can't easily reach), and is the only one with both native Obsidian export and a Claude MCP integration for searching your archive from inside an AI conversation.
XBrain.live's answer
The founder had liked over 4,000 tweets across several years and kept hitting the same wall: X's search doesn't work on your own likes, so anything saved was effectively gone. Rebuilding notes on topics already researched once became the breaking point, which led to building a semantic search and classification pipeline over the official X data archive export.
XBrain.live's answer
Next.js 16 (App Router, React 19) on Vercel, Supabase (PostgreSQL + pgvector) for storage and vector search, Stripe for payment, Resend for email, and OpenAI, Anthropic, or Gemini for embeddings and classification depending on the key in use.
