Grais is a desktop browser extension that reads the conversation open in your browser and drafts a reply in your voice. You review and edit the draft before sending by default. New contacts start in review.
It is built around six messaging jobs: answering a message you have been staring at for days, clearing a pile of unread DMs, handling LinkedIn and sales replies that would otherwise go cold, writing in a language that is not your first (including the casual register), working out what a message appears to be asking for from the visible thread, and keeping one person straight across dating apps after the match.
It helps with existing conversations. It does not run outbound campaigns, send connection requests, or act as a CRM. The public page also notes it covers five messaging platforms, and the iPhone app is still on TestFlight.
A short guide to who Grais is built for lists one page for each job.
