What Poli is
Poli is a grammar correction and translation assistant offered as a browser extension and macOS desktop app. It explains each grammar correction by identifying the rule and why the original wording was wrong. Translation covers more than 20 languages and includes explanations of phrasing choices and idiomatic nuances. A history of previous corrections and translations helps users review recurring weak spots. The Chrome extension works on sites including Gmail, Slack, Google Docs, and LinkedIn. Configurable shortcuts trigger correction and translation; the listed shortcuts are ⌥⇧C and ⌥⇧T. Poli says it is powered by Anthropic’s Claude. It also says text is encrypted during transmission, processed by AI, immediately deleted, and never stored as content. The free plan includes 10 corrections, 10 translations, four languages, and seven-day history. Paid subscriptions renew monthly or annually through Apple in-app purchases and can be cancelled in Apple account settings.
