Private beta — built in public

Stop posting into the void.
Grow by replying.

Under 5k followers, your posts barely get seen — replies are how accounts actually grow. ReplySonar hears the conversations about to blow up, drafts the reply in your voice, and shows you which replies earned you followers.

How it works

The radar hears it first

We watch your niche and detect posts whose engagement is accelerating — while they're still fresh enough that an early reply gets seen.

Reply in your voice

Three drafts written in your voice, trained on your own best tweets. Not generic AI replies — replies that sound like you.

See which replies earn followers

Every reply is measured. ReplySonar shows you which conversations — and which kinds of replies — actually bring followers in.

The receipt nobody else can show you

Growth advice is full of vibes. ReplySonar gives you receipts: follower attribution for every reply you post.
