Offsend — Mask Secrets Before Sending to AI 제작자: Lab13

Get your prompts AI-ready before you hit send — right inside ChatGPT, Claude, Gemini, and other web AI chats.

As you type into a web AI chat, Offsend spots API keys, tokens, private keys, passwords, and personal data (PII) locally, and lets you mask or redact them before a single character leaves your device. Changed your mind? One-click Restore brings the originals back.

Works with ChatGPT, Claude, Gemini, Perplexity, DeepSeek, and Grok. Offsend is not affiliated with OpenAI, Anthropic, Google, or any AI provider.

LOCAL-FIRST BY DESIGN
Your prompts never leave the device for scanning. No cloud account. No server-side scanning. No "trust us." The extension uses the network only for licensing/updates and an optional anonymous "active install" ping — never prompt content, findings, or which sites you use. It's one toggle away from off.

WHY YOU'LL WANT IT
• Catch secrets before AI sees them — emails, phone numbers, IDs, API keys, tokens, private keys, cards, and more, detected when you hit send.
• Mask, don't lose meaning — sensitive values become stable placeholders like {{API_KEY_1}}, so your prompt still reads clearly to the AI.
• Reversible Restore — encrypted, time-limited mappings let you bring originals back when you need them.
• Zero findings, zero friction — nothing sensitive in your text? Offsend stays out of your way completely.
• Honest about coverage — if a site changes its layout, Offsend tells you protection is degraded instead of pretending you're covered.

HOW IT WORKS
1. You write or paste a prompt and press Enter (or click Send).
2. Offsend scans the text locally for sensitive values.
3. Nothing found? It sends untouched.
4. Something found? You choose: Mask, Send anyway, or Cancel — or let auto-mask handle it with a quiet toast.
5. Masked values are saved as encrypted, time-limited mappings so Restore can undo it.

Everything runs in your browser. Sensitive content is never uploaded for scanning.
