Chat with your X bookmarks
Brainy is the chatbot inside Bookmarx, built so you can chat with your X (Twitter) bookmarks instead of scrolling through them. Ask a question in your own words and Brainy answers from the posts you've saved, then shows you which saves the answer came from.
Saving is the easy part
You save a thread because you'll need it later. Later arrives, and that thread is buried under two hundred newer saves, with no way back in except scrolling and squinting at thumbnails until something looks familiar.
Keyword search doesn't rescue you either, because memory doesn't store keywords. You remember that someone made a sharp argument about pricing, not the exact words they used to make it. That gap between how you remember ideas and how search matches text is where most bookmarks go to die.
How it works
- Connect your X account once. From the day you connect, every save you make syncs into Bookmarx automatically. There's no extension to install and no change to how you bookmark.
- Let the groundwork happen. Each save gets an AI summary and key takeaways plus tags the moment it arrives, and same topic saves group themselves into collections. That enriched material is what Brainy reads.
- Ask Brainy. Open the chat anywhere in Bookmarx, ask in plain language, and get an answer grounded in your saves, with the source posts cited so you can click through to the originals.
What a chat actually looks like
You: I've saved a bunch of threads about pricing lately. What did they say about usage based pricing versus flat tiers?
Brainy: Three of your saves cover this directly. A thread you saved from a SaaS founder argues usage based pricing only works once customers can predict their bill, and recommends a spend cap for the first year. Another save makes the opposite case: flat tiers close deals faster because procurement teams push back on variable line items. A third, from a pricing consultant, splits the difference with a platform fee plus a metered usage layer. All three are cited under this answer if you want the full arguments.
That's the shape of it. A synthesized answer, disagreements between your saves surfaced rather than averaged away, and citations back to the posts so the original thinking is one tap away.
What it doesn't do
Brainy won't answer from the open web, and it can't speak for anything you saved before connecting Bookmarx. It knows every save you've made from the day you connected, and when your saves don't cover a topic, it tells you so. I consider that a feature: an honest "you haven't saved anything on this" beats a confident guess.
Where it fits
Brainy sits on top of everything else Bookmarx builds for you. Summaries give it clean material to reason over, auto collections give it structure, and the digest resurfaces the saves you haven't thought to ask about yet. The rest of the lineup is on the features hub.
Frequently asked questions
What is Brainy?
Brainy is the chatbot built into Bookmarx. You ask questions in plain language and it answers from the posts you've saved on X, citing the specific saves each answer draws on.
Does Brainy answer from the whole internet?
No. Brainy is grounded in your saves. If you haven't saved anything on a topic, it says so instead of guessing, which is the point: you're querying your own curation, not the open web.
Which bookmarks can Brainy see?
Every save you make from the day you connect your X account. Bookmarx syncs new saves automatically, summarizes and tags them, and that enriched material is what Brainy searches.
Do I need a browser extension for this?
No. Bookmarx connects to your X account directly, with nothing to install in your browser. You keep bookmarking on X the way you always have.
