Riffwise

Key facts: Riffwise is a desktop Chrome extension (Mac, Windows, Chromebook; mobile Chrome does not run extensions) that writes reply drafts from the conversation you are already in — Draft → Review → Insert. It drafts replies and quotes for X, Threads, Bluesky and Gmail. Voice settings (tone, reply length, emoji use, and your own writing instructions) keep drafts in your voice. It is in beta, with a free plan available. Nothing posts or sends without you — nothing is posted, sent or scheduled automatically.

Plans: Free €0 — 40 successful generations per calendar month, no card required. Pro €5.99/month or €49 billed yearly — 500 generations per month. Paid checkout is via Paddle as merchant of record. One generation is one reply, quote or rewrite draft; failed requests are refunded.

Best for: People who reply a lot on X, Threads, Bluesky or Gmail and want quick drafts in their own voice. Who should skip it: anyone who wants fully automatic posting or scheduling (nothing posts or sends without you), or anyone on mobile Chrome or a browser other than desktop Chrome.
