PromptBuilder - AI Prompt Optimizer Pro Plan: Lifetime Subscription

Build, Test & Share Prompts From One Team Library

Prompt Builder turns a rough, plain-English idea into a finished, model-ready AI prompt in seconds, with fill-in fields for the details only you know. Pick one of 10 prompt types and one of 10 target models, from ChatGPT and Claude to Llama and DeepSeek, and you get a prompt written for that model.

 

You don’t need an API key because the AI models are included. Credits are simple: 1 credit covers one generated prompt, one optimization or one Prompt Tester message, and refining a prompt costs just 0.1 credit. Every plan includes every feature, so your plan only sets how many credits you get each month.

 

You can ask a free chatbot to draft a prompt, but you’ll be copying it between tabs and starting over each time. Prompt Builder keeps everything in one workspace. You can rebuild your old prompts with the Optimizer, run any prompt on six AI models before you use it, and set your tone and rules once so every prompt follows them. You also get 900+ ready-made prompts covering marketing, SEO, coding, support and more.

 

When a prompt works, save it to a library your whole team can search. The free Chrome extension inserts it straight into ChatGPT, Claude, Gemini and six other AI sites.
