Protect names and private details before using text with AI. Detection, replacement, and restoration happen locally on your iPhone. PromptShield helps you remove unnecessary identifying information before pasting work or personal text into an AI assistant, email, form, or message. Paste or share text, review suggested replacements, and copy a safer version using consistent aliases such as [Person 1] and [Email 1]. Free features: • Detect email addresses, phone numbers, links, dates, and long numbers. • Review every replacement before it is applied. • Exclude false positives and copy anonymized text. • Import text using the iOS Share Extension. PromptShield Pro is a one-time purchase that adds people, organization, and place detection, custom confidential terms, editable aliases, and local restoration of aliases in AI replies. Your text stays on your device. PromptShield has no account, advertising, analytics, or tracking SDK. Automatic detection can miss private information. Always review the result before sharing it. PromptShield does not guarantee anonymity or certify regulatory compliance.
