Marvin — Reddit Marketing & Reply Assistant

Your next customers are already talking. Marvin helps you join the conversation — in your own voice, on your own terms. Marvin is a social engagement agent for early-stage founders who do their own marketing. The Marvin web app (gomarvin.run) watches Reddit for conversations that match your product and emails you a shortlist worth replying to. This extension is the drafting half: when you open one of those threads (or any Reddit post you'd like to reply to), Marvin reads the full discussion on the page and helps you write a reply that actually fits it. HOW IT WORKS 1. Sign in once on gomarvin.run — the extension picks up your session automatically. 2. Open a Reddit thread, either from your Marvin digest or on your own. 3. Marvin reads the thread and proposes a few angles for engaging — answer the question, share your experience, offer a resource. 4. Pick an angle and a draft appears in a copy-ready box. Refine it through chat: "shorter", "less salesy", "end with a question". 5. Copy the reply (or insert it into the reply box) and post it yourself. Your drafts and sent replies sync to your Marvin history, so over time Marvin learns how you actually write — the gap between what it drafted and what you sent is the tuning signal. WHAT MARVIN WILL NOT DO Marvin never posts on your behalf. There is no code path that submits anything on your behalf — the most it does is proposing a reply, and you always hit send yourself. WHAT YOU NEED A Marvin account at gomarvin.run. Discovery (finding the conversations) happens in the web app; this extension is where drafting happens. X and LinkedIn support are coming soon.
