The feed wastes your time
You open X to engage. An hour later you have scrolled past the posts that mattered.
Cold posts eat the scroll
Most of what you see is already cooled off. Reply anyway and you are talking into an empty room.
Good replies arrive late
By the time you craft something worth posting, the thread has moved on without you.
AI drafts sound like AI
Generic assistants erase your voice. Editing them takes as long as writing from scratch.
How it works
From install to first reply in minutes. No complex setup.
Install the extension
Add Synapt to Chrome in two clicks. Explore the feed overlay before you commit.
Spot heating posts
Open X and see velocity on posts in real time. Filter toward Fired Posts when you want signal, not noise.
Fill your Knowledge Base
Add expertise, interests, and writing style so drafts sound like you — not a generic AI voice.
Draft, edit, ship
Generate a reply under the post, tighten the line, and post while the thread is still moving.
