OpenReply review
A Gmail-focused AI writer with model choice, tone controls, and credit-based pricing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OpenReply is a Chrome extension for Gmail users who want AI assistance while writing email. It generates contextual replies from current Gmail threads, composes new messages, and rewrites existing text. Users can choose among multiple AI models, select tones such as professional, casual, concise, or detailed, and insert generated drafts directly into Gmail. An API is also listed among its platforms, while Gmail is the supported mail client.
Its pricing structure gives buyers several ways to start. The Starter plan includes free starter credits, requires no card, and provides 200+ replies to start. Pay as you go uses credits for each AI reply, with costs varying by selected AI model and optional auto top-up available. The Monthly subscription is optional and adds 15% bonus credits. This approach suits occasional users who want to begin without a card, as well as regular users who prefer a subscription-based credit bonus, but usage depends on the selected model and the number of replies needed.
OpenReply’s main strength is its focused Gmail workflow: it works from the current thread, supports guided prompts and tone controls, and places the result in the compose interface. The service says email content is processed temporarily and not stored. Its narrow platform scope is also the key limitation. Buyers who live in Gmail and value model choice should find the feature set relevant; teams seeking broad mail-client coverage or reusable custom writing instructions should consider a tool with those capabilities instead.
