Engage on X while the thread is still moving
See view velocity. Filter Fired Posts. Draft replies that sound like you.
Synapt is a Chrome extension for X: spot posts that are heating up, skip the cold scroll, and ship a reply you actually wrote the last pass on.
The problem
Most X engagement advice ignores timing
A clever reply on a dead post is still a dead reply.
Cold posts look busy
Likes accumulate after the peak. Without velocity, you waste time under threads that already cooled.
Late arrivals don’t compound
The first thoughtful replies get the visibility. Showing up an hour late is usually noise.
AI that sounds like spam
Your account is a reputation. Drafts need your voice and a human edit every time.
How it works
From install to first reply
Minutes, not a migration. No content calendar to rebuild. Just the feed you already live in.
Install the Chrome extension
Add Synapt from the Chrome Web Store. Sign in, paste your API key once. It lives under the posts you already read.
Spot what's still heating up
On X, see view velocity on posts in real time. Filter toward Fired Posts when you want signal, not another cold scroll.
Add a short Knowledge Base
Who you are, what you build, how you sound. Optional, but it keeps drafts from reading like generic AI.
Draft, edit, ship
Generate under the post, tighten the line, post while the thread is still moving. You stay in control of every send.
