You don’t go to AI. AI comes to you.
Selection AI lives in your menu bar. Select text in any app and it offers the right action: rewrite what you're writing, or explain, research and search what you're reading.
Interactive demo
This is a scripted demo. In the app, answers are written live for your selection.
Everyday uses
The same two steps everywhere: select the text, pick an action.
Your language policy, one click away
Many teams write under rules: a style guide, a brand voice, or an inclusive-language policy that asks for gender-neutral wording in job posts, announcements and customer emails.
Write those rules once as a writing mode. It appears in the Rewrite menu in every app, and anyone on the team can apply it to a draft.
- Inclusive language
- Plain language
- Person-first language
- Your brand voice
Inclusive language
- Address groups as “everyone” or “team”, not “guys”.
- Use gender-neutral titles: “chair”, “salesperson”, “staffing”.
- Use “they” when you don’t know someone’s gender.
Before
Hey guys, each manager should send his staffing plan to the chairman by Friday.
After
Hi everyone, each manager should send their staffing plan to the chair by Friday.
The right action for the text you pick
Selection AI checks whether the selected text is editable. Writing gets rewrite tools. Reading gets tools for understanding.
When you're writing
Rewrite
Improve, fix grammar, make it shorter or longer, professional, casual or simpler. Press ⌘↩ and the new version replaces your selection in place.

When you're reading
Explain, Translate, Research, Search
Explain breaks down jargon in plain language. Translate puts it in your language. Search gives a quick answer from the web. Research reads several pages and writes a short brief. Web answers list their sources.
Ask AI
Ask your own question about the selection, then keep going with follow-ups.
Copy and paste
Copy the selection or the answer, or paste an answer over editable text.
Works across apps
Browsers, editors, mail, notes, chat and Terminal.
Chats and history
Open the Selection AI window for longer chats, and to find past rewrites, research and answers.

Questions
What does it cost?
Selection AI is free for 50 actions a month of Rewrite, Explain, Search and Ask AI. Pro makes those unlimited, under our Fair Use Policy, and adds Research, up to 100 runs a month.
Why does it ask for permission on first launch?
macOS requires your permission before an app can read the text you select in other apps and replace it. You can turn it off at any time in System Settings.
Does it work in every app?
It works in most apps, including browsers and Electron apps. A few apps don't share their selected text with macOS, and the action bar won't appear there.
Is it on the Mac App Store?
No. Apps on the App Store can't read text in other apps. Selection AI is signed with an Apple Developer ID and notarized by Apple, so macOS opens it without warnings.
Can I turn off the automatic pop-up?
Yes. Switch off "Show Actions on Selection" in the menu bar and use "Show Actions for Current Selection" when you want it.
