Robin Singhvi
Founder, Gramms
I built Gramms as a solo founder. It's an iOS app for AI-narrated personalized bedtime stories told in a parent or grandparent's actual voice (cloned from a 30-second recording), for children ages 3–10. Everything you read on this blog about voice cloning, read-along design, COPPA-compliant kids' apps, and bedtime routines comes from building and shipping the product.
What I focus on
- AI bedtime stories — prompt design, age-banding, narrative craft
- Voice cloning for kids — Cartesia Sonic, audio capture UX, parental consent
- Early literacy — read-along design, dwell time, story length
- Native iOS — Expo + React Native, background audio, lock-screen queue
- COPPA-compliant product design — what data we collect, what we don't
Talk to me
I do 30-minute calls with parents weighing options. No sales pitch — just a chat about your evenings and whether Gramms (or one of the others) is the right fit.
