Native AI actions for macOS
Summarize or translate selected text in Safari, Slack, Mail, Preview, Xcode—anywhere ⌘C works. No paste box. No context switch.
Works wherever Copy works
One gesture · two daily actions
Summary and Translation are always available on every captured item. Set a default, then switch whenever the job changes.
Short or detailed. In the source language or one of twelve output languages. Add your own instructions when the default is not enough.
Ship the onboarding refresh Friday. Keep the current provider flow. Move plugin polish to the next release.
ContextAI detects the source language, preserves Markdown and structure, and translates to the language you actually use.

Made for everyday use
The gesture stays simple. Everything behind it—from content detection to persistent history—is built for work you repeat every day.
ContextAI understands the whole clipboard payload and keeps useful source metadata for the AI.
Sign in with ChatGPT or bring an OpenAI, OpenRouter, Gemini, or Claude API key.
Original source, application, content type, provider metadata, Summary and Translation survive restarts. Results render as selectable Markdown and copy in one click.
A compact indicator stays under the notch. The full result opens only when it has something to show.
Copy Markdown or publish from the result through focused Notion and Obsidian plugins.
Choose Summary or Translation as the default, tune the double-copy interval, and record a global shortcut. Both actions always remain available.
No Accessibility or Input Monitoring permission. Credentials live in macOS Keychain and history stays in local Application Support.
Native onboarding, a Finder “Summarize with ContextAI” Service, menu-bar access, trackpad back navigation, and a floating mode for displays without a notch.
How it works
No new capture workflow to memorize. ContextAI reacts to a normal Copy gesture and stays compact until the result is ready.
Highlight text—or copy a supported file or image—in the app you are using.
Press ⌘C twice within your configured interval. ContextAI starts the default action.
Read, copy, switch action, revisit History, or publish to a configured plugin.
