Mac AI assistant

AI text actions on selected text, in any Mac app

Highlight a sentence, paragraph, or message, press a shortcut, and Syneli translates, cleans up, or rewrites the selection in place.

We probably can't ship today because the last build still has issues and I need one more day

Rewritten in place

We need one more day before shipping. The latest build still has a few issues, and I want the release to feel solid.

Select. Shortcut. Done.

Syneli is not only for new dictation. It also helps with text that is already written, so you can fix, translate, or restyle it without leaving the app you are using.

Translate selected text on Mac

Select text in Slack, Mail, Notes, a browser, or an editor, then replace it with a translation using your shortcut.

Rewrite selected text in a style

Turn rough wording into professional, concise, friendly, or clear writing while keeping your current workflow.

Clean up rough text

Remove filler words, restarts, and messy phrasing from dictated or typed text before you send it.

Built for the places you already write

Syneli works around the active text field instead of asking you to paste text into a separate writing app.

For work messages

Clean up a Slack update, make an email more confident, or translate a short reply without rebuilding the message elsewhere.

For notes, docs, and editors

Use the same selected-text action in notes, documents, browser fields, and developer tools where extension-based writing tools may not fit.

Selected text and dictation belong together

Speak when you are starting from a blank field. Select text when the words already exist. Syneli gives both workflows the same shortcut-first feel.

FAQ

How is this different from normal dictation?

Dictation creates new text. Selected-text actions transform text that already exists, such as a draft, message, or paragraph.

Can Syneli translate highlighted text?

Yes. Select the text, choose your translation shortcut, and Syneli replaces the selection with the translation.

Can I use writing styles on selected text?

Yes. Selected text can be rewritten into useful styles such as professional, concise, friendly, or clear.

Does local dictation still work?

Yes. Syneli keeps local voice-to-text as a core workflow and adds selected-text actions for text that is already written.
