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 Repair PDF?

Repairing a PDF rebuilds the internal structure of a file that is damaged, for example after an interrupted download, a failed save, or a faulty export from another program. A PDF contains a cross-reference table that tells readers where every page and object lives; when that table or some objects are broken, viewers refuse to open the file or show blank pages. SuperPrompts' free Repair PDF tool parses the file tolerantly, recovers every object it can read, and writes a fresh, valid PDF with a new cross-reference table. Pages that are recoverable keep their original text and images. Repair cannot recreate data that is completely missing, but it fixes the most common structural faults in seconds.

Frequently asked questions

Why won't my PDF open?

Most often the file was cut off during download or saved incorrectly, which breaks its internal index. Repair PDF rebuilds that index.

Can every PDF be repaired?

Not always. If parts of the file are completely missing, those pages can't be recovered, but the rest usually can.

Is Repair PDF free?

Yes, it is free to use.

Will repair change my content?

No. It only rebuilds the file structure; recovered pages keep their original content.
