Typefully for writing. Synapt for the reply.
An alternative when growth comes from conversations, not only composed posts.
Typefully shines as a clean editor and scheduler across networks. Synapt sits in Chrome to help you spot heating posts on X and draft replies that still sound like you.
The problem
A great editor doesn’t pick the thread for you
Publishing your own work and joining other people’s conversations are different jobs.
Compose vs engage
Scheduling threads doesn’t surface other posts while they’re still accelerating.
Late to the conversation
By the time you leave the editor and open the feed, the best reply slots may be gone.
Voice under pressure
You need drafts in the feed, fast, without sounding like a template.
Honest take
Different jobs. Be honest about which one you need.
Typefullyand 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.
