Prompt Studio
Local AI workspace
Ship safer prompts with a local, testable AI workspace.
Prompt Studio keeps every prompt, test, and model integration on your machine. Design flows, run evaluations, and push clean prompts with zero data exhaust.

Why now
Prompt work deserves the same rigor as code.
Teams keep experimenting in web chat UIs without auditability or privacy controls. Prompt Studio brings local-first guardrails so you can move fast and keep data safe.
Prompts live in the cloud
Sensitive context leaks into hosted tools and chat logs.
No repeatable tests
Results shift between runs without baselines or evals.
Scattered assets
Prompts, notes, and scripts end up across repos and docs.
What Prompt Studio does
A private control room for prompt design, testing, and shipping.
Keep your prompt lifecycle in one local tool. Capture context, version prompts, and run automated checks before anything leaves your machine.
Local-only workspace
Work entirely on-device with controllable model endpoints and zero third-party storage.
Prompt pipelines
Compose prompts, contexts, and guards as repeatable flows you can re-run or schedule.
Versioned artifacts
Commit prompts, tests, and datasets together so every release has an audit trail.
Evaluation baked in
Ship only when acceptance checks and red-team suites stay green.
Capabilities
Everything you need to keep prompts reliable.
From individual prompt sketching to production rollouts, Prompt Studio keeps the loop tight and private.
Secure by default
Runs fully local with explicit network toggles for any outbound model calls.
Versioned prompts
Git-friendly project structure keeps prompts, tests, and datasets together.
Evaluation suites
Red-team and regression checks with pass/fail gates before deploy.
Metrics that matter
Track drift, latency, and acceptance scores across prompt variants.
Smart scaffolds
Starter templates for agents, chat, and retrieval flows to move faster.
Offline friendly
No cloud login required. Works even when you are disconnected.
In the product
Keep your prompts and tests in one clean workspace.

Evaluation results that gate releases
Run suites on-demand or in CI. Prompt Studio highlights regressions before they ship.
Privacy first
Your prompts never leave your machine.
Prompt Studio ships as a locally installed app. Telemetry is off by default. When you opt in, only anonymous performance metrics are sent—no prompts, datasets, or identifiers ever leave the device.
Data ownership
You keep the keys
- No cloud sync unless you explicitly connect your own storage.
- Model credentials and datasets stay encrypted locally.
- Observability panels only show what you choose to log.
When enabled, only anonymous performance data is sent: app version, OS, GPU/CPU presence, and crash dumps with sensitive strings stripped.
FAQ
Answers to common questions.
Still curious? Reach out and we will share the security note, deployment guide, or roadmap details you need.
Is Prompt Studio cloud dependent?
No. Everything runs locally by default. You can connect external endpoints you control, but nothing leaves your device without you enabling it.
Which models does it support?
Anything with an OpenAI-compatible API, plus local models via your own runtimes. Bring your keys or point to self-hosted gateways.
How do evaluations work?
Create suites of test prompts and acceptance criteria, then run them against prompt versions. Results gate releases and can be run in CI.
Can multiple people collaborate?
Yes. Projects are file-based and Git-friendly, so teams can branch, review, and merge prompt changes like code.
Is telemetry required?
Telemetry is off by default. If you opt in, only anonymous performance metrics are shared—never raw prompts or datasets.
Does it include a CLI?
A bundled CLI mirrors the app. Run evaluations headlessly, export reports, and enforce pass/fail checks inside pipelines.
Which platforms are supported?
macOS and Windows are first-class today, with Linux builds in early preview.
