Hey Sumo-lings! 🚀
I'm Nick, founder of Prompt Builder (promptbuilder.cc). Thanks for stopping by. Here's the short story.
We all hit the same wall with AI: you know the model can do more, but getting there means endless back-and-forth. You rewrite the same prompt five times, then redo it for Claude or Gemini because what worked in one falls flat in another. An hour later you've got an okay result, and no way to reproduce it tomorrow.
Prompt Builder kills that loop. It's a full workspace to GENERATE → OPTIMIZE → TEST → SAVE & REUSE, all in one place:
• Prompt Generator: describe your goal (type, voice, or attach up to 10 files), pick a prompt type (Standard, Research, Writing, Code, Agent, Image, Video, Automation…) and a target model, and get a production-ready prompt built for it.
• Prompt Optimizer: paste a prompt you already use. It asks up to 3 quick questions, then rewrites it with clear constraints, acceptance criteria, and an explicit output format (JSON, table, checklist).
• Prompt Tester: run and iterate on your prompt in a chat-first workspace, right inside the app. No switching to ChatGPT to see if it works.
• Instructions: set standing rules once ("Be concise," "Don't sound like AI") and they're woven into every prompt automatically.
• Prompt Library: save with categories, tags, and models; pin your best; search and filter instantly. Start from Community Prompts and make them yours.
It's tuned for 10 model targets (Universal, ChatGPT, Claude, Gemini, Llama, Mistral, DeepSeek, Perplexity, Grok, and Cohere), so the same idea gets shaped correctly for whichever you use. Great for marketers, founders, developers, agencies, researchers, and content creators.
WHY THIS DEAL? Prompt Builder normally runs on a monthly subscription ([$9–$49/mo]). This is a LIFETIME deal: pay once and the prompt workflow you'll use every day is yours for good. Early supporters also help shape what ships next (see my roadmap post 👇).
Push it hard and tell me where it falls short. You're covered by AppSumo's 60-day money-back guarantee, so there's no risk in kicking the tires.
