I built a free tool that roasts Twitter profiles — now it sells my paid service for me

I run a Twitter growth service. Yes, the industry everyone assumes is a scam. Because most of it is.

That was my biggest problem. Not the product — the trust.

So I stopped trying to convince people and built TweetScan — a free Chrome extension that audits any Twitter profile in seconds. Engagement rate, fake follower %, content breakdown, honest A-F grade.

Completely free. No login. Works on every profile page on X.

Why give it away?

1. Someone scans their profile

2. They see their engagement is trash and their followers are 30% bots

3. Now they want to fix it

4. There's a "Grow with TweetBoost" button right there

Give away the diagnosis. Sell the cure.

The extension runs 100% client-side — zero API cost. The deeper follower audit hits our API but is capped at 1/day free.

Every profile page on X now has our widget. Every competitor check = our brand impression.

Lesson: If you're selling a service nobody trusts, stop writing better copy. Build a free tool that demonstrates your expertise. The doctor doesn't charge you to say you're sick.

Happy to answer questions about the build or the model.
