Riffwise

Riffwise is a Chrome extension for the moment you're staring at an empty reply box. On X, Threads, Bluesky and Gmail, you right-click inside the composer and pick Write a reply or Create quote text, and it drafts from the conversation you're answering using your saved tone, length and emoji settings. You edit the draft, then choose Insert or Copy. It never posts or sends on its own. The free plan includes 40 generations a month with no card, Pro is €5.99 a month for 500, and it needs an account and desktop Chrome. Its privacy policy says the text you're replying to and any attached post media go to OpenAI to produce the draft, and that Riffwise doesn't intentionally keep prompts or replies in its own database.
