Conseal. Use AI on any document. Privately.

01 · Anonymize

Names out. Tokens in. Mapping stays local.

Conseal swaps every PII item for a semantic token like Person_1.
The mapping is saved locally, ready to restore any document that uses the same tokens.

The problem

You want AI. Compliance says no.

Manual redaction

Hours spent manually blacking out names, addresses, and account numbers. Document by document. Line by line.

Skipping AI

Enterprise tools

How it works

Three steps. Zero data leaves your machine.

Step 01

Drop your file

Open a PDF, Word doc, or text file. Conseal scans it locally.

Step 02

Pick a mode

Anonymize swaps PII for placeholders. Restore reverses the swap from the mapping. Redact blacks PII out permanently.

Step 03

Send the clean file anywhere

Paste into ChatGPT, Claude, Gemini, or any AI. Originals stay local in Saved Tokens.
