CREATOR MODE
The fastest loop from idea to applet.
Generate, deploy, test, screenshot-verify, patch, and rollback — all from your desktop. The builder loop is your superpower.
THE LOOP
The build-deploy-verify loop
Prompt or write a spec
Describe what you need in natural language, or write a JSON spec directly. The builder generates everything.
Deploy to your phone
One command sends the applet to your phone. No app store, no review, no wait.
Screenshot verification
The builder automatically captures screenshots and verifies the layout matches intent.
Run automated tests
Test flows execute against the running applet. Assertions on state, UI, and behavior.
Patch or rollback
Fix issues and redeploy instantly. If something breaks, rollback to any previous version.
Evidence bundle
Every deployment generates a bundle: spec, screenshots, test results, capability manifest.
FLEXIBLE
Your machine. Your builder.
The builder runs on your desktop — Claude Desktop, your own server, or any MCP-compatible client. Local-first means your data stays on your hardware, and you control compute costs.
Local-first privacy
Specs, assets, and data never leave your machine unless you choose to share them.
Zero latency
No round-trip to the cloud. Build and deploy as fast as your machine allows.
Pluggable backends
Start with Claude Desktop. Swap in any MCP client later — or build your own.
TRUST
Every deployment tells a story.
When you deploy an applet, Spec4AI Studio generates an evidence bundle:
- The complete spec (JSON)
- Screenshot captures of every screen
- Test results with pass/fail
- Capability manifest (declared permissions)
- Builder signature (who built it, when)
Evidence bundles are what make applets trustable. Runners can inspect exactly what an applet does before installing.
WORKFLOW
Fork, build, share.
See an applet you like? Fork it into your workspace. Modify the spec, add features, re-test, and publish your version — or keep it private.
Publish to channels
Share your applets through channels. Subscribers get updates automatically.
