Email Polisher for Gmail

Email Polisher for Gmail takes a deliberately narrow approach to AI writing help. Instead of a full composing suite, it adds a single "Polish" button to the Gmail compose window. When you click it, the text of your draft is sent to the developer's GPT API, which analyses it and returns suggestions covering grammar, sentence style, and word choice. You review the proposed edits and decide whether to accept or reject them, keeping final control over what actually gets sent.

The extension is aimed at people who write a lot of email and want a fast quality gate rather than a rewrite. Its Chrome Web Store description frames it as useful both for professionals trying to sharpen their written communication and for anyone who simply wants clearer, more concise, error-free messages without hiring an editor. The installation footprint is tiny — around 340 KB — and the interface stays inside Gmail, so there is no separate editor to learn or tab to switch to.

The listing shows version 1.0.1, last updated in March 2023, with a 5.0 rating from a small handful of reviews and roughly 560 users. The developer declares that personally identifiable information and personal communications are handled, but states that data is not sold to third parties, not used for purposes unrelated to the extension's core functionality, and not used to determine creditworthiness or for lending. Because the store page does not publish plan details, users who need exact pricing information should check the developer's support site before installing.
