Buffer for the calendar. Synapt for the reply.
An alternative when growth comes from conversations, not only scheduled posts.
Buffer makes publishing consistent. Synapt sits in your Chrome feed to show what’s heating up on X and draft replies that still sound like you.
The problem
A full queue doesn’t mean you’re in the right threads
If Buffer already covers publishing, the remaining gap is usually finding posts still worth a reply.
Publish ≠ engage
Scheduling your own content doesn’t surface other people’s posts while they’re still accelerating.
Late to the conversation
By the time you notice a thread, the good reply slots are gone.
Generic AI helpers
Most reply tools sound like the same intern. Synapt starts from your tone and Knowledge Base. You still edit.
Honest take
Different jobs. Be honest about which one you need.
Bufferand 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.
