Nothing is ever uploaded
Detection and redaction run entirely on your computer, so every page and every word stays with you.
Redact sensitive data offline,before uploading to ChatGPT.
Protect your clients’ privacy whenever you share documents. RedactGuru finds and permanently removes sensitive details from PDFs and scans.
Sharing tenancy agreements and property correspondence requires care with personal information. RedactGuru makes it straightforward to review and redact names, contact details and bank account numbers before sharing a separate copy—all within the desktop app, even offline.

Scanning on your computer…
Your documents stay on your computer
RedactGuru Desktop detects and redacts on your device. Your documents and redaction records are not uploaded to our servers.
Go ahead, turn off Wi‑Fi
Works offlineDisconnect and redact a document. It works exactly the same, because it never needed the internet.
Built on open source
Presidio · MITDetection is built on Presidio, the open-source framework for finding personal data, extended with our own rules and validators.
Nothing uploaded, nothing stored on our servers
Your documents and redaction history stay on your computer—not on our servers.
Real redaction, not black boxes
Many tools just draw a box over the text, and the words underneath can still be selected and copied. RedactGuru flattens each redacted page, so what you remove is actually gone.
Double-checked before you save
After redacting, RedactGuru reads the finished page again to make sure nothing you removed can still be found.
Knows what to look for
Review contact details, identifiers and TFN found in your documents. Add details the detection missed before sharing.

Redact for AI without losing the meaning
Numbered labels like [Name 1] keep who's who, so ChatGPT and other AI tools still give their best analysis. Mask and Black box are there too.

Redact a whole folder, consistently
Open a folder and RedactGuru finds the same details across every document, then replaces them all at once. [Name 1] in the lease is [Name 1] in the amendment too, so contracts and complex case files still make sense together.
