Later plans the grid. Synapt works the feed.
Only an alternative if engagement, not visual scheduling, is the bottleneck.
Later is excellent for planning Instagram and visual content. Synapt is a Chrome extension for spotting heating posts on X and drafting replies that sound like you.
The problem
A beautiful calendar doesn’t find the reply
If your growth loop is public conversation, you need signal in the feed, not another drag-and-drop grid.
Visual planning ≠ thread timing
Scheduling your own posts doesn’t show which other posts are accelerating right now.
Wrong surface
Later is at home in visual planners. Synapt lives under the posts you’re already reading in Chrome.
Voice still missing
You still need drafts that match how you write, then a human edit before send.
Honest take
Different jobs. Be honest about which one you need.
Laterand Synapt aren't drop-in replacements. Pick the tool that matches the work you actually do.

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.
