Hey Product Hunt! 👋 I’m Jakib, the maker of Postworth. The influencer marketing space has a massive transparency problem. Creators constantly undersell themselves because they don't know their data-backed worth, and marketers often overpay because they lack a quick "BS detector" for engagement rates. I built Postworth to fix this. It’s a dual-sided social post valuator. You drop in your basic stats, and our algorithm calculates a suggested post rate based on 2026 industry benchmarks. But I wanted to make the data actionable and viral. Postworth generates a premium, shareable "Social Influence Certificate" (designed like a vertical ID card) complete with a snarky AI "Vibe Check" on your engagement. It’s built to be downloaded and attached to media kits or sent straight to brands to justify your pricing. I built this MVP rapidly using Next.js and a "vibe coding" workflow with AI agents. I’d love for you to try it out! Generate your certificate, and let me know below: Did the AI roast your engagement, or did you hit "Legendary" status? I'll be hanging out in the comments all day to answer questions and hear your feedback!
