Work context for
your AI

Yes! Stubble is fully open source under the Apache 2.0 license. We believe privacy-focused software should be transparent and auditable. You can explore the code, contribute improvements, or self-host on your own infrastructure. Check it out at github.com/stubbleapp/Stubble.

Screenshots are captured and stored locally on your Mac—they're never uploaded. OCR runs on-device using Apple's Vision framework. For AI features like task summarization and chat, sanitized text summaries (with secrets stripped) are sent to our AI backend. Your raw screenshots never leave your device.

Stubble uses on-device OCR to extract text from screenshots, then sends sanitized summaries to Gemini for AI processing. Sensitive data like passwords, API keys, and tokens are automatically stripped before anything leaves your Mac. The AI helps organize your day into tasks and projects, and powers the chat features.

Stubble tracks any app you use on macOS. It reads window titles and app names to understand what you're working on. For browsers, it can see the page title of your active tab. You can exclude specific apps or websites from tracking in settings.

Yes! Export your time data as CSV to import into any time tracking or invoicing tool. We also support MCP (Model Context Protocol), so AI coding agents like Claude Code can access your work context directly.

No. Stubble is optimized for Apple Silicon and uses minimal resources. It takes screenshots at smart intervals (not constantly) and processes them efficiently. Most users don't notice any performance impact.
