X Brain vs Fabric
These solve different-sized problems. Fabric is a general workspace for everything you save; X Brain is narrowly built for one thing, your X/Twitter likes. Which fits depends on how much of your saved content is actually tweets.
| X Brain | Fabric | |
|---|---|---|
| Price | $4.99 once | Free tier, paid plans roughly $6 to $16/month depending on tier |
| Scope | Built specifically for X/Twitter likes | General AI workspace: bookmarks, files, PDFs, notes, voice memos, and more. Twitter is one input among many |
| How it gets your tweets | Upload the official X archive, your whole history at once | Browser extension or web clipper, one item at a time as you save it |
| Covers your full historical archive | Yes, including likes X's own UI no longer loads | No, only what you've clipped going forward |
| Search type | Semantic, by meaning, plus AI classification into your own likes' categories | Semantic search across your whole workspace, plus AI chat and drafting |
| Export | CSV, JSON, Markdown, Obsidian vault | No dedicated Obsidian export found at the time of writing |
| Claude / MCP integration | Yes | Has its own AI assistant; no Claude/MCP integration found |
| Where your data lives | Your X Brain account | Fabric's cloud workspace |
| Ongoing subscription | No | Yes, on paid tiers |
Choose X Brain if
- You want your entire Twitter/X likes history imported at once, not just what you save from today.
- Twitter/X is specifically what you’re organizing, not your whole digital life.
- You want Claude able to search your saved posts.
- You’d rather pay once than run an ongoing subscription.
Choose Fabric if
- You want one workspace for everything you save, not just tweets: bookmarks, PDFs, notes, voice memos.
- You’re fine saving items one at a time as you go, rather than a bulk historical import.
- You want AI chat and drafting over your whole saved library, not just search.
Fabric’s pricing and feature set were checked against its own site in September 2026; its published pricing tiers vary across sources, so confirm current numbers on fabric.so before deciding. If something here is out of date, let us know and we’ll fix it.
