## Features

### Summary — AI text summarizer for Mac

Choose a short summary when you only need the point, or a detailed one when the
context matters.

### Translation — AI translator for Mac

Switch the target language without copying the source again. Names, links, code,
dates and structure stay intact.

### The whole workflow — summarize or translate with a double ⌘C

No window switching and no paste box. The result opens beneath the notch, over
the app you are already using. A single ⌘C never triggers anything; press Escape
to dismiss the result instantly.

## Plugins and what's next

- **Plugins — Notion and Obsidian plugins.** Send it where it belongs. Notion
  and Obsidian are the first plugins. More are coming.
- **Coming soon — summaries for pages.** Copy a link the same way — double ⌘C —
  and the notch summarizes the whole page behind it.

## Built for everything you copy on your Mac

- **Developers** — Summarize long issues, PR threads, and error logs without leaving the editor. Translate docs and comments in place.
- **Content and Marketing** — Condense briefs, research, and competitor pages into key points before they get lost in tabs.
- **Sales and Support** — Translate customer messages instantly and reply in their language without switching apps.
- **Founders and Operators** — Skim investor updates, contracts, and long email threads in seconds instead of reading everything twice.
- **Students and Research** — Turn dense papers and articles into clear takeaways you can actually remember.
- **Everyday Use** — Translate anything you copy — recipes, posts, messages, tickets — the moment you copy it.

## Frequently Asked Questions

### What is ContextAI?

ContextAI is a macOS app that summarizes or translates any text you copy. Select text in any app, press ⌘C twice, and the result appears in the notch — no window switching, no paste box.

### Where is my history stored?

Your history is stored locally on your Mac. ContextAI does not use cloud sync, user accounts, or server-side storage.

### Does ContextAI upload my copied text?

Copied text is sent only to the AI provider you connected — ChatGPT, OpenAI, or OpenRouter — to generate the summary or translation. ContextAI has no servers of its own and never stores your content anywhere else.

### Which AI providers are supported?

You can sign in with your ChatGPT account, use an OpenAI API key, or connect OpenRouter to pick from many models. Your provider, your model.

### Can I revisit previous items?

Yes. Every capture is saved to history, and both Summary and Translation stay available as tabs on each item, so you can reopen anything later.

### Will it react to every copy?

No. A single ⌘C never triggers anything. ContextAI only activates on a deliberate double ⌘C, so your normal copy workflow stays untouched.

### Can I dismiss a result quickly?

Yes. Press Escape and the notch closes immediately — even while a response is still streaming, it will not reopen on its own.

### Can I send results to other apps?

Yes. Plugins let you save a result to Notion or Obsidian in one click, and you can copy it to the clipboard anytime.

### Is ContextAI a subscription?

No. ContextAI is free. You bring your own AI provider — a ChatGPT account or an API key — and pay only for what your provider charges.

### How do I install the app?

Download the DMG, drag ContextAI to Applications, and launch it. It needs macOS 15 or later, and the app checks for updates itself and tells you when a new version is ready to install.
