AI Prompt Management and Document Anonymization—100 % Locally On-Device. SafePrompt protects private data when you work with generative AI. Built for professionals in law, education, medicine, and for anyone who values privacy, it scrubs personally identifiable information from text and lets you store reusable prompts, all without sending raw content off your iPhone or iPad. Key Features: - Automatic Anonymization – Names, IDs, emails, and other information are replaced with clear placeholders. - Prompt Library – Save, tag, and reuse your favourite AI prompts for consistent results. - Local-Only Processing – Text never leaves your device; no external cloud or human review. - Flexible Import – Open Microsoft Word™ (.docx), PDF, and plain-text files, or paste text directly. - Share Your Way – Copy the cleaned text to the clipboard or use the iOS/iPadOS share sheet to hand it off to ChatGPT™, Claude™, Grok™, or any other AI client. (All product names are trademarks of their respective owners; SafePrompt is not affiliated with these services.) SafePrompt helps you use AI confidently when privacy is non-negotiable. Automatic processing isn’t fool-proof: you can add or remove items from the anonymization, and you should always review the output carefully before sharing it.
