Atelier Prompt Studio 2.0 beta: a free single-file offline prompt builder for images and video
SuperCasualGamerDad · reddit · 2026-09-28
Atelier Prompt Studio 2.0 beta is a visual prompt-building tool shipped as a single HTML file — fully local, offline, no AI calls, no account or API key. You craft prompts there, then paste them into your own image or video workflow. Open source on GitHub.
What's new in 2.0:
- Dual Create / Edit modes: build image prompts from scratch or describe changes to an existing image
- Compose characters, outfits, backgrounds, lighting, styles, camera choices and finishing effects; separate pose and movement libraries including multi-character assignments and video motion descriptions
- Pick individual pieces of presets; visual color pickers for eyes, hair, makeup and more
- Visibility-aware conflict detection: if gloves hide your chosen nail details, it resolves just that conflict instead of dropping the whole outfit; also flags crops that hide selected details
- Custom presets, saved looks, import/export; optional content kit expanded via an external AI tool
The author is not a programmer and built it entirely with AI-assisted coding. Beta feedback welcome.
