New version of Mycroft Sweeper 1.4.3 – higher precision in detecting personal data

The Mycroft Sweeper 1.4.3 update significantly improves the accuracy of detecting personal data – including names, addresses, and document numbers. Fewer false positives, greater precision, and enhanced stability.


We’ve released Mycroft Sweeper 1.4.3, the desktop application for local document anonymization compliant with GDPR. This update focuses on improving the accuracy of personal data detection and enhancing the overall stability of the application. The upgraded AI algorithms now distinguish personal data from ordinary text more effectively, resulting in greater precision and fewer false positives during anonymization.

What’s new in version 1.4.3

Improved recognition of names, surnames, and addresses Thanks to enhanced language models, Mycroft Sweeper detects personal data more accurately – regardless of grammatical form or context.

Better validation of document identifiers (DocumentIdPl, TaxIdPl) Updated validation rules and additional safeguards reduce false detections and improve overall reliability of the analysis.

More stable scanner performance Optimized scanning logic and refined settings deliver more consistent and predictable results.
