Audio and podcasting decision
Hypnothera.ai
A capable developer can reproduce the core personalized script+TTS flow and credited subscription for an individual user in about a week; advanced features like multi-seat practice workspaces, voice cloning, polished mobile apps, and commercial licensing are the main differentiators to the hosted product.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Hypnothera.ai alternatives, with the arithmetic →
What a replacement has to do
- User answers prompts → generate personalized script (LLM) → render to audio (TTS) → allow edit/preview → deliver session (stream/download).
What it still won’t have
- Polished mobile apps (iOS/Android) and app-store distribution
- Branded practice workspace, team seats, and built-in analytics/dashboard
- Voice-cloning (multiple voice clones) as shipped
- Priority support and polished UX flows (journeys, playlists, streak tracking)
- Commercial licensing and attribution controls as packaged
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a single-tenant web service in Node.js/Express + React (Vite) with Postgres, deploy to a single AWS ECS/Fargate service and S3 for audio storage; core features: (1) user signup/login, credit balance and Stripe subscription for monthly credits (200 credits by default), (2) prompt-driven script generation endpoint that calls an LLM API and saves editable script text, (3) TTS pipeline that converts scripts to MP3 via a commercial TTS API and stores output in S3 with streaming URLs, (4) web UI for creating/editing scripts, choosing voice, previewing and playing/downloading audio, (5) admin UI to view usage and credit consumption. Out of scope: native mobile apps, multi-tenant practice workspace, voice cloning training. Include input validation, error handling, CI tests for core flows (script generation, TTS rendering, payments), and deployment scripts (infrastructure as code) plus basic automated backups and logging.
