Blackout scans any text document — transcripts, reports, research notes, HR files — for names, organizations, projects, and sensitive data. Redact or code-name everything in seconds, then export a clean version you can safely share, file, or feed into AI tools.

Paste any sensitive document. Blackout flags every risk. Choose how to handle each one — then export exactly what you need.
ORG-1 to ORG-2.
RESPONDENT [00:00:19]
PERSON-A brought me in for PROJECT-1. There was a SENSITIVE-1 that PERSON-B didn't want disclosed.
CODE Readable but anonymousPaste any text — transcripts from Otter, Zoom, or Granola; reports, research notes, HR documents, legal memos. If you can copy it, Blackout can process it.
An instant pattern scan catches names, orgs, and keywords. Upgrade to AI Deep Scan to catch subtler references — things mentioned in passing that rules-based scanning misses.
Click any highlighted term to black it out, assign a code name, or mark it safe. Review by category — handle all people at once, or go one by one.
Export as plain text, Markdown, Word doc, or PDF. If you used code names, download the decoder key separately and store it away from the document.
Every export format is designed for a real workflow — from quick file attachments to formatted client deliverables.
Clean, portable. Works everywhere. Great for archiving or pasting into other tools.
Speaker labels formatted as headings. Paste straight into Notion, Obsidian, or GitHub.
Formatted for sharing with clients or filing in document management systems.
Print-ready, professional. Ideal for legal review, compliance filing, or formal delivery.
A JSON file mapping every code name back to the real term. Store it securely, separately from the sanitized document.
Sanitize client interview transcripts and internal reports before filing in shared drives or presenting findings to other teams.
Anonymize participant transcripts and research notes to meet IRB requirements and protect respondent identity in publications.
Redact privileged information and sensitive figures from transcripts and memos before sharing across matters or teams.
Protect source identity in working documents while keeping the full context accessible for your own review.
Anonymize interview transcripts and investigation notes for sharing with stakeholders who don't need to know who said what.
Share user research transcripts and session notes with stakeholders without exposing participant names or identifying details.
The tool you use to protect private documents shouldn't itself be a privacy risk.
All pattern-matching and redaction runs locally in JavaScript. Your text is never transmitted to our servers for this step — when you close the tab, it's gone.
The optional AI scan sends your text to Blackout's secure backend, which calls Claude AI on your behalf. Your content is processed and returned — never logged or stored.
When you use code names, the decoder key is a file you download and control. Blackout never holds it. The sanitized document is meaningless without it.
An account stores only your email and subscription status. No document content, no scan history, no activity logs — ever.
Start free. Upgrade when you need .docx, .pdf, and the decoder key.
3 complete exports. Full redaction, code-naming, AI scan. No credit card needed.
Unlimited exports, Word, PDF, and the decoder key. Cancel anytime.
No. For pattern-based redaction, everything runs in your browser — nothing is transmitted anywhere. For the AI scan, your text is sent to Blackout's secure backend to process the AI request, but it is never stored, logged, or retained. When you close the tab, it's gone.
The AI scan sends your text to Blackout's secure server, which passes it to Claude AI for analysis. Claude identifies names, organizations, projects, and sensitive items that pattern-matching rules miss — things mentioned in passing, indirect references, or context-dependent details. The result comes back to your browser. Nothing is stored.
Instead of blacking out a term, you can replace it with a neutral label like PERSON-A or ORG-1. This keeps the document readable while hiding the real identity. When you export, you can download a JSON decoder key that maps each code name back to the real term. Store that key separately from the document — ideally in a password manager or encrypted folder.
Not for the free tier. You can paste, scan, redact, and export .txt and .md files without creating an account. An account is required for Pro features (.docx, .pdf, decoder key download) and to track your AI scan usage.
Anything you can paste as text. Transcripts from Otter, Zoom, Granola, or Rev; reports and memos from Word or Google Docs; research notes; HR documents; legal correspondence. If you can copy the text, Blackout can process it.
Blackout uses passwordless magic link login. Enter your email, get a link, click it. No password to remember or to leak.
Yes. Cancel anytime from the Account panel inside the app. You keep Pro access until the end of the billing period.
Blackout takes five minutes to learn and protects every name, number, and detail you're not ready to share — every time you use it.
