Years of likes, sorted one swipe at a time
Your likes pile up into thousands of posts you never see again. X Brain turns them into cards with the key takeaway on top. Keep what still matters, save what to act on, and hide the noise.
Try it: swipe the card, tap the buttons, or use the arrow keys.
Put stable prompt content before the cache breakpoint to cut LLM costs.
Prompt caching cut our model bill by 70%. Stable system prompt and tool definitions first, cache breakpoint after them, anything that changes per request after that. Most teams get the order backwards.
Three moves, three lists
Swipe right: Keep
Still worth having. Kept posts stay in search and get their own list.
Swipe up: Act on it
A tool to try, a post to write, an idea to follow up. They collect in one list, ready when you are.
Swipe left: Noise
Jokes, old news, things you liked by accident. Noise drops out of your search results, so the rest gets easier to find.
Start with your oldest likes to rediscover what you saved years ago, take one category at a time, or shuffle. Sorting works alongside searching your likes by meaning: the more noise you file away, the sharper your search results get.
Questions
Does sorting unlike the posts on X?
No. Sorting only changes your X Brain library. Your likes on X stay exactly as they are, and X Brain never posts, unlikes or changes anything on your account.
What happens to posts I mark as noise?
They are hidden from your search results, and the dashboard tells you how many were hidden, with a link to show them. They stay in your library, so you can move any of them back from the Noise list at any time.
Which order do the cards come in?
Three choices: oldest first, to rediscover things you liked years ago; the posts the classifier was least sure about first; or shuffled. You can also sort one category at a time.
Can I undo a swipe?
Yes. Undo brings back the last card, and every list lets you move a post to another list or back into the deck.
Do I lose my sorting if I upload a newer archive?
No. Your choices are saved against each post's X ID, so they carry over when you replace your archive with a newer one. Delete All Data in Settings removes them.
Does it work on a phone?
Yes, it is built for phones first: swipe with your thumb. On a computer you can drag, click the buttons, or use the arrow keys.
How do I get my likes into X Brain?
Request your data archive in X's settings. X usually takes about 24 hours to prepare it, sometimes up to 72. Upload the ZIP to X Brain, and after the one-time $4.99 payment your likes are classified, tagged and ready to sort.
Sort your own likes
$4.99 once, no subscription. Search, classification, takeaways, export and Sort included.
