Show HN: Mystwright – AI generates dynamic murder mysteries you can solve

I built Mystwright, an AI-powered "murder" mystery game engine.

(Other mystery types are possible too! But I'm still working on making those feel right.)

Instead of pre-written cases, Mystwright procedurally generates a world, a crime, and a cast of suspects — each with unique motives, relationships, and secrets. You investigate in any order: interview suspects, search for clues, follow leads. The story adapts as you play.

Core mechanics:

- Procedural mystery generation (no two games are the same)

- Seeded mystery worlds

- Procedural dialogue generation

- Distinct character personalities

- Consistent timelines and evidence trails

- Generative voice dialogue

- Location exploration experiments are underway

I'd love feedback on:

- Does the mystery feel engaging/coherent?

- Ideas for mechanics that would make solving more satisfying

- Is it too easy, too hard, or just right?

- Etc!

*Also there are some worlds I have made public (under the community tab) which I consider some decent examples. Feel free to try those so you don't have to wait for a world to generate!*

Would love your thoughts!

P.S. Re: pricing - You can use the service for free to a point. Right now you can make 1 world, send up to 30 messages to characters, and can only use the default model which is not the fastest but is well rounded.
