Hey Product Hunt! 👋
I'm Guillaume, solo developer from France, and I built SignalWhisperBot because I was drowning in voice messages during meetings.
The problem:
My contacts send long Signal voice messages. I prefer reading to listening, but there was no transcription solution that worked within Signal.
The journey:
Started summer 2024, built the first version in 2 months as a side project alongside my freelance work.
Had 2 paying users in January, then one cancelled. I almost quit in March.
Then May happened. Multiple paying users. Consistent revenue. Validation.
Today:
Customers in 10+ countries, thousands of transcriptions monthly.
How it works:
→ Forward any Signal voice message to the bot
→ Get instant text transcription
→ Free tier available (10 messages or 10 minutes/month)
Key features:
→ 95-98% accuracy (Whisper V3 AI)
→ Immediate audio deletion (< 2 seconds)
→ Email routing - send transcriptions to colleagues
