How it works: Load a transcript → smart scanner auto-detects names, emails, phones, URLs and more → click to confirm or add redactions → optionally run an AI deep scan for comprehensive detection → export as clean text, FBI redacted, or code-named with reversible key file. 100% free for local scanning. AI deep scan available to all logged-in users — free or Pro.

⚠ Always review before sharing. Blackout helps identify sensitive content — it does not guarantee completeness. You are responsible for the final document.
Restore

Only works with the Code Named export — not Clean Text or the black-bar version. Paste your code-named document below (or drop a .txt file onto it), then upload your decoder key to reverse the codenames back to the originals.

🛡 Trust & Safety
Blackout is designed with a security-first architecture. Here's exactly how your data is handled.
Local Processing — Always On

Every transcript you load is processed entirely in your browser using JavaScript. The text never touches a server. All redaction, tokenization, codename generation, and export happens in memory on your device. When you close the tab, the transcript is gone — nothing is stored except your dictionary (in localStorage, which you control).

You can verify this yourself: right-click → View Source. No transcript data ever reaches a server. The only network request that carries your transcript content is the optional AI deep scan — and only when you explicitly click that button. Auth requests (sign-in, session restore) carry only your email address and a Supabase session token — never transcript content.

AI Deep Scan — Optional, Explicit, Transparent

When you click AI Deep Scan, your transcript text is sent to Claude via a secure server-side proxy. This is the only moment transcript data leaves your machine — and only when you click the button.

What Claude sees: Your transcript text, plus a system prompt asking it to identify entities. Nothing else.

What Claude does with it: Anthropic's API has a zero data retention policy for API calls. Your transcript is not stored, not logged, not used for training, and not accessible to any human at Anthropic. It is processed and immediately discarded.

When it's offline: The button is grayed out. No request is attempted. If a request fails (no network, wrong endpoint), the tool catches the error locally and shows you the error. No data is cached or queued for retry.

The Proxy Endpoint

When you click "Deep Scan," your transcript is sent to a secure API endpoint that forwards it to Claude. Your Anthropic API key is stored server-side — it never appears in the browser, in the page source, or in any response. You authenticate with your email, and the server handles the rest.

If you don't have a Pro subscription, the AI scan is simply unavailable. The rest of the tool works identically.

What's Stored Locally

localStorage (browser only, you control):

• Your redaction dictionary (terms + types) — so you don't re-enter names every session
• Your session count — so the free tier limit persists between visits
• A Supabase session token (auto-managed) — so you stay logged in
• Nothing else. No transcripts. No exports. No history.

Clear your browser data to remove everything. Or click "Clear" in the sidebar.

Unlock AI Deep Scan

Claude reads your entire transcript and catches what pattern matching can't — names mentioned in passing, project references buried in conversation, subtle sensitive details a human would flag but a regex never would.
