The problem
Audience growth dies in a dead thread
Great replies on cold posts don’t compound. Timing and voice both matter.
You can’t feel velocity by eye
A post with lots of likes can already be cooling. View-per-minute style signal helps you prioritize.
AI that sounds like AI
Your audience follows you for a specific voice. Template replies erode that.
Engagement is unpaid labor
If the workflow isn't fast, you'll skip it, and growth stalls.
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.
