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.

How does this plagiarism checker work?

The SuperPrompts Plagiarism Checker compares your text with sources you provide and highlights passages that are too similar, so you can rewrite or cite them before you submit. It is designed for checking a draft against the articles, notes or earlier work you actually used: paste the source text, or compare against documents saved in your SuperPrompts library. It does not crawl the web or a database of published papers, so it will not find matches in sources you have not given it. That makes it useful for checking your own paraphrasing, comparing two versions of a document, or making sure you have not copied too closely from your research notes. If a passage is flagged, rewrite it in your own words with the Paraphrasing Tool and add a citation.
