PromptBuilder takes a rough idea in plain English and turns it into a finished prompt for the model you choose, such as ChatGPT, Claude, Gemini, Llama, Mistral or DeepSeek. You pick one of 10 prompt types, fill in the details only you know, and copy the result. The AI models are included, so no API key is needed.
It also rebuilds old prompts with an optimizer, lets you test a prompt on six models before you use it, and keeps saved prompts in a searchable library your team can share. A free Chrome extension inserts saved prompts into ChatGPT, Claude, Gemini and other AI sites.
This is the Starter plan: lifetime access with 1,000 credits a month. One credit covers a generated prompt, an optimization or a tester message; refining a prompt costs 0.1 credit. Every plan has every feature, only the monthly credits differ. Licenses do not stack, and the deal is open to new and existing users. Unredeemed licenses can be returned for store credit within 30 days.
