Title:"28 days ago I had an idea. Today I have beta testers. Here's what happened.

28 days ago I posted on Reddit
asking freelancers one question.

"What frustrates you most about
AI email tools?"

I expected complaints about speed.

34 people responded.
Every single one said the same thing:

"It doesn't sound like me."

One comment I couldn't stop thinking about:
"I spend more time fixing the AI reply
than writing it myself.
What's even the point?"

That became Replyf.

Gmail Chrome extension that learns
your personal writing tone from
your own sent emails.
One click inside Gmail.
Sounds like you wrote it.
Not like AI.

What I built in 28 days:
→ Full Chrome extension
→ Tone learning from your emails
→ AI reply generation
→ Payment integration
→ Website live

What surprised me:
→ Gmail DOM is brutal (SPA navigation)
→ Making AI sound human is hard
→ Finding first users is harder than building
→ But the right message gets responses

Launching publicly Soon.
Beta access available now.

If you handle client emails daily
and are tired of robotic AI replies —
I'd love your honest feedback.

What has been your experience with
finding first users before launch?
