VibeSell
A Chrome extension that, when you click “Engage” on a Reddit post, returns three human, product-personalized reply drafts — you copy, edit and post.

Reddit is flooded with AI-generated comments — obvious slop that no one respects and communities penalize. Yet it's still one of the highest purchase-intent places online. The challenge: help product owners take part genuinely and at scale, without slipping into spam — with a person always deciding before publishing.
The principle is the opposite of slop: the tool suggests, the human decides. Nothing is posted automatically. An “Engage” button on threads generates three short, relevant drafts (1–3 sentences), personalized to the product and to a chosen directness level — you copy, tweak and post.
The intelligence comes from the Anthropic API (Claude). Underneath, a lean architecture: static site, Express backend with a REST API, magic-link login and Stripe payments for the SaaS model — all on Vercel, with continuous deployment and per-plan usage limits.
A Chrome drafting extension inside Reddit, a marketing site and an account area with magic-link login, plan dashboard and a usage meter. SaaS monetization with Stripe (plans and daily limits); the paid plan unlocks auto-discovery, voice match and direct mode.


The proof came from the real world: I used the extension itself to promote my How To Invest project on Reddit. Even with a first MVP, that channel brought over 150 users and around 200 sessions (GA4) — one of the project's biggest traffic sources. That's VibeSell's core argument: genuine participation, with human control, drives real visits without burning the brand. The product is in pre-launch, with the full SaaS stack (extension, auth, payments).
