Replai

About Replai

Replai is an AI email assistant whose central claim is stylistic rather than functional: it learns what the company calls your Reply Identity — the specific way you phrase things, your greeting and sign-off habits, how formal you are with which correspondents — and drafts replies in that voice rather than in generic assistant English. That is the differentiator it argues in its own comparison pages against Fyxer, Superhuman, SaneBox, Shortwave, Gemini and Copilot. The product is broader than a reply generator. It covers inbox triage and prioritisation, labelling, AI-written full emails from bullet points, scheduling with booking links and calendar sync, and meeting recording with unlimited transcripts and speaker diarization on the paid tier. It connects to Gmail and Outlook natively, and to Yahoo, Fastmail and anything else over IMAP through a custom email setup path, which is unusually open for this category — most AI email tools are Gmail-only. The free email reply generator is genuinely free and, importantly, requires no account and no inbox access at all, so the core capability can be evaluated before granting a tool read access to your mail. Paid pricing is at the low end of the AI-email market; the company leads with "simple, honest pricing" and a $6/month Pro tier billed annually, against competitors that typically sit at $20–30 per seat.
