What is SuperPrompts?

SuperPrompts is an AI prompt optimization tool that rewrites your rough input into model-specific, structured instructions. Paste any prompt, choose your target AI (ChatGPT, Gemini, Claude, Grok, and more), and get a precision-engineered version in seconds.

How much does SuperPrompts cost?

SuperPrompts is free — you get 20 AI-optimized prompts per day with no credit card required. You can earn additional bonus credits through the referral and review program.

What AI models does SuperPrompts support?

SuperPrompts supports ChatGPT (GPT-4), Google Gemini, Anthropic Claude, Grok (xAI), Kimi, and Lovable — each with model-specific optimization, not generic rewrites.

Does SuperPrompts have a Chrome Extension?

Yes. The Chrome Extension works directly inside ChatGPT, Claude, Gemini, and other AI interfaces so you can optimize prompts without leaving the page. Install it from the Install Extension page.

What makes SuperPrompts different from writing prompts myself?

Our Structured Blueprinting Engine adds role framing, output format constraints, context tuning, and model-specific language patterns automatically. The result is fewer follow-up messages and higher-quality AI output on the first try.

Does SuperPrompts work for coding and technical prompts?

Absolutely. SuperPrompts is popular with developers for SQL queries, code review requests, debugging prompts, and generating clean JSON structured data. The tool adds proper technical context and output constraints automatically.

Is my data secure with SuperPrompts?

Yes. Prompts are processed through trusted AI providers (OpenAI, Google, Anthropic) under strict data protection standards. SuperPrompts is built and operated by Backuplan LLC. Contact: support@backuplan.in.

What is an image converter?

An image converter changes a picture from one file format to another, for example JPG to PNG or PNG to WebP, so it works where you need it. JPG is best for photos and small files, PNG keeps sharp edges and transparent backgrounds, and WebP gives smaller files for websites. The SuperPrompts Image Converter outputs JPG, PNG and WebP and accepts any image your browser can open. It runs entirely in your browser using the canvas API, which means your images are never uploaded and there is no waiting for a server. You can convert several images at once, choose a quality level, or set a target file size in KB, and crop each image with a simple drag-to-crop box before downloading. It is free, with no watermark.
