ShadowQuill
A local, offline prompt-engineering studio that turns rough ideas into structured prompts using self-hosted Gemma models through Ollama, with no cloud API, account or network access required after setup.
ShadowQuill is a local prompt studio that turns rough ideas into structured prompts, running entirely against Ollama and locally hosted Google Gemma models with no cloud API call, account or network access needed once it is set up. It offers eight tabs for keeping several prompts open at once, seven task types covering intent, engineering, visual, motion, analysis, narrative and persuasion prompts, ten default presets as starting points for common workflows, a Preset Studio for building custom presets with a live preview, and version history for stepping back and forward through a prompt's revisions.
Setup requires Ollama installed locally with at least one Gemma model pulled, after which the app is installed and run with pnpm. Projects, presets and configuration are stored only on the local disk, and the project states that it sends no telemetry.
It is built with Next.js, Electron, React and TypeScript, and is MIT licensed.
