THE EXTRA WORK BEFORE THE WORK

Less manual redaction.
More time for the draft.

The email is ready to paste. So are the client's name, email address and case reference. Removing those details by hand adds another task before AI can help with the first one.

Hushbridge gives you a version to review with detected details already replaced. Keep the request, check what remains, then send it to AI.

Start with one piece of text. See exactly what changes before you decide whether to use it.

FROM PROMPT TO REPLY

Get the original
details back.

Placeholders help keep the request readable. Your local swap table restores the original values in supported replies, so you can work with names and details again.

Scan on your device

Hushbridge looks for names, contact details, identifiers and secrets in the text.

02

Review before sharing

Check the protected version for missed details and identifying context before you send it to AI.

SDK & LOCAL PROXY

Build protection
into your AI app.

Run detection in your own process. Review protected text before the model call, then restore values with the local swap table.

The developer overview is available now. Expanded documentation pages are in preparation.

Local protectionTypeScript
import { protect, restore } from 'tightlip';

const safe = protect(prompt, { profile: 'legal' });

// Review safe.text before your model call.
// Keep safe.vault in your local process.

const original = restore(safe.text, safe.vault);

Local round-trip example. Add your own model integration to work with AI replies.

BEFORE YOU TRY IT

Your questions,
answered.

What does Hushbridge actually do?

It scans text on your device, replaces detected names, contact details and other sensitive values with placeholders, and keeps a local table for restoring them. You review the result before using it with AI.

Do I need to change AI tools?

The browser extension supports ChatGPT, Claude, Gemini, Copilot and Perplexity. It currently requires manual installation. You can try the detection engine here before installing anything.

Will my prompt still make sense?

The instructions and surrounding text remain. Consistent placeholders help preserve the relationship between people and details. Compare the original and protected versions in the demo above.

Does the free check send my text to an AI model?

No. Detection and restoration run in this browser. The check does not call an AI model, generate an answer or use paid credits.

Does it remove every sensitive detail?

No detector catches everything. Review the output for missed details and identifying context. The extension does not scan attachments, and an AI website may read text while you type. For sensitive text, check it here before pasting it into an AI website.

What happens after the free check?

You can review installation steps, choose a paid workflow or use the SDK in your own app. Paid use is metered in credits at USD 0.05 each, with prepaid top-ups starting at USD 100. See pricing for the rules for each workflow.
