What Poli is
Poli is a grammar correction and translation assistant available as a browser extension and a macOS desktop app. It explains grammar corrections by describing the rule and why the original wording was wrong. For translation, it covers more than 20 languages and explains phrasing choices and idiomatic nuances. A history of past corrections and translations, including their explanations, helps users review recurring weak spots.
The Chrome extension works on websites including Gmail, Slack, Google Docs and LinkedIn. Configurable keyboard shortcuts trigger correction and translation; the listed shortcuts are ⌥⇧C and ⌥⇧T. Poli says its AI is powered by Anthropic's Claude. It says text is sent encrypted for AI processing, immediately deleted afterward and never stored as content.
Poli offers a free plan with 10 corrections, 10 translations, four languages and a seven-day history. Its listed Starter plan provides 50 corrections and 50 translations per day, all languages and a 30-day history. Pro includes 500 daily corrections and translations, all languages, unlimited history, custom shortcuts, and custom tone and style. Paid subscriptions renew monthly or annually according to the selected plan, and Apple manages payment through Mac App Store in-app purchases. Poli is made by Poli, headquartered in Lyon, France.
