About Repl1

Repl1 is a Chrome extension and web app that drafts email replies inside Gmail. When you open an email, a Repl1 button appears in the interface. One click produces a draft that matches the tone of the conversation and the language of the thread, which you can edit or send as is, with no copy-paste into another tool and no prompt to write.

Pro features let you tell Repl1 what to include, avoid or emphasize, such as dates, budgets or promises you cannot make, and refine a draft as shorter, warmer or more direct. The site says it reads only the email you are answering, and only when you click, with no background scanning or stored data. The free plan includes 20 replies per month, and the extension can be tried without an account.
