Hi Product Hunt! 👋 I'm Guney, the maker behind Promptheon. I built Promptheon out of a personal frustration that I’m sure many of you share: the absolute chaos of managing AI workflows. Every day, I found myself crafting complex, high-value prompts, only to lose them in endless ChatGPT or Claude chat logs. When working with teams, sharing these prompts meant copying and pasting into messy Slack threads or clunky Notion docs. On top of that, we were constantly hitting usage caps on $20/mo consumer subscriptions. I wanted a clean, developer-centric environment. So, I built the platform I wished existed. Here is what makes Promptheon different: The Vault: Save, organize, and version-control your best prompts. No more lost context. Zero API Markups (BYOK): Bring your own OpenAI, Anthropic, or Gemini keys. You pay the provider directly. We don't upcharge you a single cent. Live Canvas & Chained Labs: Don't just store prompts—run, test, and chain them directly inside our dashboard. Team Workspaces & Prompt DNA: Share your top-performing prompts and pre-assigned variables across your entire team with full role-based access control (RBAC). Promptheon actually started as a simple B2C prompt library. But as we tested it, the process completely evolved. After talking to founders and tech leads, it became clear that the real bottleneck was collaboration. We rebuilt the entire architecture into a multiplayer B2B SaaS because teams desperately needed a single source of truth for their AI operations. I'm incredibly excited to finally share this with the PH community. To celebrate the launch, we are offering a 20% discount on all Annual Plans. I’ll be hanging out in the comments all day. I’d love to hear your brutal, unfiltered feedback on the UI, the BYOK model, or anything else! Let's ship better prompts. 🚀
