What OpenReply is
OpenReply is a browser extension that adds AI-assisted writing to Gmail. It reads an email thread and places a contextual draft in Gmail’s compose box for review and sending. Clicking AI starts a draft, while shift-click can auto-draft; Draft and More controls add detail or change the model. The homepage says OpenReply supports more than 40 AI models and automatically adds new ones. The Starter plan costs nothing and includes credits described as enough for 200+ replies to start, with no card required. After those credits, pay-as-you-go generation costs vary by selected model, with example per-reply prices shown on the homepage. Teams can request custom pricing and features, with a stated response time of 24 hours. The maker says email content is processed in memory and immediately discarded. Thread content is sent through the OpenReply API to AI providers without sharing the user’s identity. Browser-to-server traffic uses TLS 1.3. The extension requests storage, activeTab, scripting, identity, and mail.google.com access, which the maker says is limited to Gmail. Bring-your-own API key support is coming soon.
