Show HN: Zomni – An AI sleep coach that personalizes CBT-I for everyday use

Hi HN,

We built Zomni because we were tired of sleep trackers that show data but don’t help you actually sleep better.

Zomni is a personal sleep coach powered by AI and rooted in CBT-I, the most effective treatment for insomnia. It doesn't just record your sleep; it gives you a daily plan and dynamic recommendations tailored to your real habits, rhythm, and mindset.

The problem: Most sleep apps show you charts like “6h 42min” or “sleep efficiency: 78%,” but leave you wondering: now what? They often make sleep worse by encouraging unrealistic goals and reinforcing bad patterns (like over-napping or obsessing about 8 hours).

What we built:

A fully conversational AI sleep coach (built on OpenAI)

Hyper-personalized advice based on your last 3 nights of sleep

A CBT-I–based sleep plan that updates automatically

No wearables, no stress — just real habit change.

We’d love feedback — from tech, behavior, or personal perspectives.

Thanks for reading, Zomni Team
