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 AI cover letter generator?

An AI cover letter generator writes a first draft of a cover letter tailored to a specific job, so you are not starting from a blank page. The SuperPrompts Cover Letter Generator asks for your name, the job title, the company, your key skills and any extra details you want to mention, such as a project, a result or why you want the role. You choose a tone, professional, friendly, confident or enthusiastic, and it writes a structured letter with an opening, evidence of fit and a closing call to action. Edit the draft to add specifics only you know, keep it to one page, and make sure every claim is true. Pair it with the Resume Builder to match your resume to the same job description.
