NullifyHow to use
Redact a PDF in five steps.
Everything happens in your browser — your documents are never uploaded to a server. Here's the full flow, from upload to a safely redacted export.
Step 1
Upload your PDF(s)
Open the editor and drop in one or many PDFs (up to 100MB and 200 pages each). Scanned or photographed documents work too — on-device OCR reads them during AI redaction. Nothing is uploaded automatically.
Step 2
Choose Manual (free) or AI-assisted
A prompt asks how you want to work. Manual redaction is free forever — draw boxes over anything sensitive, then move, resize (drag the corner handles) or delete them until you're happy. AI-assisted mode finds sensitive information for you.
Step 3
If AI: pay once, press Go
Payment opens in a popup so your document stays loaded. Once confirmed you get a purchase code — save it, it restores your purchase if you close your browser. Press Go and Claude scans your pages in staged chunks, flagging account numbers, IDs, transactions and more. Pick a preset like Proof of Address (keeps your name and address visible) or Transactions only. Not happy with the result? One re-run is included.
Step 4
Review every suggestion
AI suggestions appear as amber boxes — click one to accept it, or dismiss it with ×. Scroll to the end of the document to unlock Accept All. You always have the final say; nothing is redacted without your review.
Step 5
Export — permanently redacted
Redactions are burned into the page pixels, not layered on top, so they can't be undone or copied out. You also get a branded PDF audit report of what was detected, accepted and dismissed. Batches download as a single ZIP.
$2.99 covers 50 pages — combined across all your PDFs
The page count is pooled over your whole batch, not per file. Upload 50 one-page bank statements in a single batch and redact them all with AI for one $2.99 payment. Beyond 50 combined pages it's just +$1 for every extra 25 pages.
- · 50 PDFs × 1 page = 50 pages = $2.99
- · 3 PDFs × 25 pages = 75 pages = $3.99
- · 1 re-run included with every payment — change presets and try again
- · No subscription, no account. Manual redaction stays free, unlimited.
Closed your browser after paying?
Use the purchase code shown at checkout — enter it under "Already paid?" in the editor to restore your unused runs. It's also remembered automatically in the same browser.
What leaves your device?
Manual mode: nothing, ever. AI mode: only extracted text — never your file — is sent over an encrypted connection. We store nothing, and your text is never used to train AI models.
