Eko · Use case
Fix grammar in any app on your Mac
Grammar checkers like Grammarly live in a browser extension or a handful of supported apps — leaving you unguarded the moment you switch to Mail, Notes, a native app, or the terminal. Eko fixes grammar system-wide: select any text anywhere on your Mac, press a shortcut, and Eko rewrites it in place, cleaned up and correctly punctuated. One shortcut, every app, no extension to install per site.
Get Eko for Mac — $39How Eko helps
Fix grammar in place, anywhere
Select a sentence or paragraph and press ⌥C. Eko corrects grammar, punctuation and phrasing and replaces the selection right there — no browser plugin needed.
Works where Grammarly doesn’t
Native Mac apps, PDFs, the terminal, Slack, Notes, Pages — anywhere you can select text, ⌥C works. Grammarly’s extension only covers the browser and a short app list.
Clean up dictated text too
Dictate a rough draft with ⌥D, then press ⌥C to tidy it up — dictation and correction share the same flow, so speaking roughly is fine.
Keep your writing private
Run Eko fully on-device with a local model so drafts and messages never leave your Mac, or bring your own API key if you prefer a cloud model.

FAQ
How do I fix grammar with Eko?
Select any text in any app and press ⌥C. Eko rewrites it with corrected grammar and punctuation and replaces the selection in place.
Is Eko a Grammarly alternative?
Yes — Eko corrects grammar system-wide instead of through a browser extension, so it works in native Mac apps, PDFs, and the terminal, not just supported websites.
Does grammar correction need the internet?
No, not necessarily. Eko can run fully on-device with a local model, so correction works offline and your text stays on your Mac — or you can use your own API key.
Can Eko fix grammar in dictated text?
Yes. Dictate with ⌥D, then select the result and press ⌥C to clean up grammar and phrasing — the two shortcuts are designed to be used together.
What does Eko cost?
Eko is $39 once, no subscription — grammar correction is included alongside dictation, translation, ask-AI, screen vision, and app-launching.
