About Hypnova

Who makes it

Hypnova is made by Zentient AI, LLC, a software company based in California, US. It was founded in 2024 by Kevin Crabbe, who is also its founder. The app went live on the US App Store in June 2025 and has shipped continuously since. Android is not released yet; there is a waitlist.

What Hypnova is not

Two unrelated things share this name. Hypnova in Zürich, at hypnova.ch, is a hypnotherapy practice run by clinicians in Switzerland. Hypnova is also the name of a pop duo from Brooklyn. Neither is connected to this app in any way, and Zentient AI, LLC has no relationship with either. If you are looking for the Swiss clinic or the band, this is the wrong site.

The 300+ free sessions

The pre-made library holds 300+ hypnotherapy sessions across 12 categories, including sleep, stress and anxiety, focus, habits, relationships, chronic pain, weight, confidence and fears. All of it is free, with no subscription and no cap on replays. This is not a trial tier: the library is free permanently, and a new account also receives 60 credits for creating sessions of its own.

The AI session

The other half of the app writes a session for you. You describe what you want to work on in a short chat, choose a length between 10 and 25 minutes, a narrator voice and an ambient soundscape, and Hypnova writes a script for that specific situation and narrates it. Creating audio spends credits, charged per minute at a rate that depends on the voice; replaying a session you already own never costs anything. Pro is $12.99 a month for 240 credits, with up to 120 rolling over, or $99.99 a year for 2880 credits granted upfront. The 7-day trial includes 80 credits.

How sessions are written and narrated

Every session, pre-made or personalized, follows the structure used in hypnotherapy practice: an induction, a deepening phase, a suggestion phase built around your goal, and an emergence. The pre-made library is written in-house from the clinical technique literature rather than by a practitioner on staff, and draws on guided imagery, verbal suggestion, progressive relaxation, breathing pacing and cognitive reframing. Personalized sessions are written by a model constrained to the same structure. Narration is synthetic, using studio-quality text-to-speech voices, mixed over an ambient bed you choose.

Safety

Hypnova is a personal wellness app. It is not a medical device, not therapy, and not a substitute for professional medical advice, diagnosis or treatment. It does not diagnose conditions and it does not replace care from a qualified provider. Do not listen to a session while driving or doing anything else that needs your attention. If you have a history of psychosis, dissociative disorders or epilepsy, or you are in crisis, speak to a healthcare professional before using hypnotherapy of any kind. The app shows this disclaimer before your first session.
