Riffwise is a Chrome extension that reads the post, message or email in front of you and drafts a reply you can edit before anything goes out. It is built and run by one person, Igor Sarkulov, from Nicosia in Cyprus, and it is aimed at people who know what they want to say but stall on the first line.
Unlike tools that post on your behalf, Riffwise stops at a draft. According to the Riffwise website, it never posts or sends anything by itself; you review the text, then insert or copy it.
Why a solo maker built a reply drafter
Sarkulov told 100xFounder by email that he built Riffwise for his own use first. He regularly writes replies to Ukrainian fundraisers and to people in his social feed, and he says the hardest part was the opening sentence: without it, the reply often never got written. What he wanted, in his words, was “a starting point, not an autopilot.”
Once the tool was useful to him, he made it public. He says he builds and operates it alone as an independent maker, and the website lists the operator as Igor Sarkulov, trading as Sarkulov, a sole proprietorship registered in Cyprus.
How the extension works
The extension sits in a side panel in desktop Chrome. You open a conversation, Riffwise reads the visible post and relevant context, and it returns a short suggested reply with two buttons: insert it into the composer, or copy it. The website lists X, Threads, Bluesky, Gmail and other web messaging as supported places. It runs on desktop Chrome on Mac, Windows and Chromebook; mobile Chrome does not run extensions.
There are personal voice settings, so drafts can follow the way you usually write. Sarkulov says making drafts hold the writer’s own voice more closely is one of the things he is working on now.
What happens to your text
For a tool that reads your inbox and feed, this is the question that matters most. According to the founder and the Riffwise privacy policy (last updated 8 October 2026), the text you work on goes over HTTPS to Riffwise’s backend and then to OpenAI, which generates the draft. The company says prompts and generated replies are not intentionally stored in its database. The extension keeps the active request and result temporarily in Chrome’s session storage, while account, subscription and monthly usage records sit in Supabase. Paid checkout runs through Paddle, which acts as merchant of record, so Riffwise does not receive card details.
Pricing and languages
The website lists two plans. Free costs nothing, needs no card and allows 40 successful generations per calendar month. Pro allows 500 generations a month for €5.99 monthly or €49 billed yearly. The site also describes the extension as being in beta.
In a follow-up email on 9 November 2026, Sarkulov said version 1.5.30 was then live on the Chrome Web Store with interface settings in English, Latin American Spanish and Brazilian Portuguese. Spanish and Portuguese pages on the website are still being prepared.
Who uses it, and what comes next
Sarkulov was candid that the user base is small and that it is too early to name a main audience. The people who have told him how they use it are mostly replying on X and handling email. He has no dated roadmap to share; his current focus, he says, is stability and better voice matching.
