AI reply generator built for the feed
Draft in your voice. Prefer heating posts on X. Stay in control of every send.
Synapt is a Chrome extension AI reply generator for people who grow by joining conversations, not by living in another scheduling dashboard.
The problem
AI replies only help if they sound like a person
Otherwise you’re just accelerating the spam everyone already ignores.
Generic models erase your brand
Without your tone and context, every draft sounds like the same intern.
Speed on the wrong post
Fast replies under cold threads waste the only scarce resource: attention.
Automation temptation
Tools that auto-post “engagement” burn trust. Drafts + human send is the durable path.
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.
