Dimkey finds and masks sensitive data — names, IDs, financials, organizations — right on your device. No uploads. No cloud.
Four steps. No account needed.
Drag in a contract, report, or any document.
Names, IDs, phone numbers, companies — all highlighted. Adjust with one click.
Get a redacted copy in the original format. Same layout, no sensitive data.
Need the original data back? Restore from your local mapping — only you can.
Three engines work in layers — regex, NER model, and your custom dictionary.
Names, SSN, passport numbers, addresses, phone numbers, email addresses
Company names, tax IDs, institutional addresses, contract and case numbers
Bank accounts, credit card numbers, salary figures, transaction amounts
Add your own sensitive terms with the built-in dictionary. You control what gets redacted.
Every redaction creates a local mapping file — an encrypted key that lets you reverse the process and recover the original data. The mapping never leaves your machine. No cloud. No key server. Only you can restore.
Redact client names, case details, and privileged information before sending contracts to AI for review or summarization.
Mask account numbers, salary data, and company financials before AI analysis of reports or invoices.
Strip client-specific details from deliverables, research data, and strategy documents before external AI processing.
Free to use. No account required.
