SanitiseAI processes sensitive text in a focused workflow designed to minimise retention risk. Content is sanitised during request handling and returned as safe-to-share structured output.
One focused action, with clear boundaries around processing and storage.
01 / Processing
Sent securely to our API
The text you choose is sent over HTTPS when you click Sanitise, use the selected-text action, or enable automatic sanitisation for a supported form submission.
Text may include personal details or credentials. Processing happens on the server, not on your device.
02 / Storage
Preferences, not prompt history
The extension stores its automatic-mode preference in browser storage. It does not keep a prompt history or include analytics or advertising scripts.
The info control shows detected categories and counts so you can understand what changed.
Core technology
Practical sanitisation controls
Multi-layered masking
Pattern heuristics and entity-based detection work together to reduce sensitive value leakage.
Consistent tokenization
Format-preserving substitution
Entity-aware detection
Entity detection improves identification in unstructured notes, contracts, and support transcripts.
Context heuristics
Alias consistency checks
Consistency checks
Post-processing checks reduce duplicate placeholders and obvious formatting leaks in anonymised output.
Placeholder cleanup
Conservative fallbacks
Secure Data Lifecycle
From ingestion to cleanup, privacy controls are applied across the full request lifecycle.
Data ingestion
Input arrives through encrypted transport and is handled in active request memory.
In-memory masking
Detection and anonymisation run in transient request scope without saving the raw document.
Secure output
Structured placeholders are returned so content remains useful while sensitive data stays protected.
Instant destruction
Temporary buffers are released after request completion as part of the normal processing lifecycle.
Data-handling controls
SanitiseAI supports safer handling of sensitive text through practical controls, documented behaviour, and reviewable operational safeguards.
