Superreply - 2026 Pricing, Features, Reviews & Alternatives

Superreply is a Chrome browser extension that embeds AI-powered reply generation directly inside Gmail and Outlook web inboxes. On any email, users click the extension icon to instantly receive three tailored response options, each ready to review, edit, and send. The free plan covers up to 90 AI-powered replies per month; paid plans unlock unlimited replies and advanced tone controls, billed monthly or annually. Team and multi-seat plans are available for organizations managing shared email workflows.

The extension analyzes full email threads to extract key topics, detect sender intent, and determine tone and urgency before generating contextually appropriate replies. Eight tone modes are supported: friendly, professional, formal, informal, inspirational, appreciative, consultative, and requestive. A tone-matching mode automatically aligns the reply tone to the incoming message. Grammar and spelling correction is applied to all generated responses. Email content is not stored on vendor servers; only usage activity data is retained, and data in transit is protected with TLS encryption.

Superreply targets individuals, freelancers, customer care representatives, sales teams, marketing agencies, and business users of all sizes who handle high volumes of email through Gmail or Outlook web via Chrome. It is particularly suited to professionals for whom English is a second language, as well as those managing customer inquiries, complaints, and sales pitches who require consistent, professional communication at scale.
