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 Redact PDF?

Redacting a PDF permanently removes sensitive information, such as account numbers, addresses, names or signatures, before you share a document. Simply drawing a black rectangle over text in a PDF editor does not redact it: the original text usually remains underneath and can be copied or searched. SuperPrompts' free Redact PDF tool lets you drag boxes over anything you want hidden, then burns the black boxes into flattened page images, so the hidden content is truly gone and cannot be selected, copied or recovered. Because the output pages are flattened, the rest of the text is also no longer selectable, which is the safest trade-off for documents leaving your hands. Redaction runs in your browser.

Frequently asked questions

Is drawing a black box the same as redacting?

No. In most editors the text stays underneath the box. Redact PDF flattens the page so the hidden content is gone.

Can redacted text be recovered?

No. The pages are flattened, so the original text no longer exists in the file.

Why is the rest of my text not selectable?

Pages are flattened to guarantee nothing hidden remains. Keep the original if you need editable text.

Is my PDF uploaded?

No. Redaction runs in your browser.
