The Problem
Organizations with large-volume document processing needs face a gap between cloud tool limitations (upload caps, rate limits, privacy concerns) and manual processing feasibility. Healthcare research organizations may have hundreds of thousands of clinical notes. Law firms receiving large productions need batch processing. Cloud upload of these volumes raises both practical (bandwidth, time) and regulatory (data residency, BAA) concerns.
Key Data Points
- Feb 2026 SDNY ruling: AI-processed documents lose attorney-client privilege if not anonymized before processing
- 73% of law firms use AI tools without systematic PII protection (Bloomberg Law 2025)
- reversible encryption enables discovery production while maintaining privilege
Real-World Use Case
A clinical research organization is building a de-identified dataset from 50,000 patient consultation notes. The hospital's IRB requires that processing occur on-site. anonym.legal's Desktop App processes the notes in 10 batches of 5,000, running overnight. The next morning, 50,000 de-identified files and a processing metadata log are ready for transfer to the research team.
How anonym.company Addresses This
Desktop App batch processing supports 1-5,000 files per batch depending on plan. Parallel execution (1-5 concurrent files) for throughput. Mixed format support in a single batch. ZIP packaging for processed files. CSV/JSON export with processing metadata. Progress tracking and error handling.
