PII-safe analytics
For: Teams whose analysts paste real data into chat windows and tools
The fastest way to get LLM help on a query is to paste real rows and identifiers into a chat window. That content crosses a boundary to a provider you do not control. l0l1 scans for PII first.
The problem
Prompts and query text carry SSNs, emails, phone numbers, and card numbers. Forwarded to an external model or stored in a log, that data leaves your control.
How l0l1 helps
l0l1 runs Microsoft Presidio plus regex over prompts and query text and anonymizes detected literals before anything is stored or forwarded to a provider. Detection is best-effort — not a legal guarantee — but it moves the default toward safety.
In this workflow
- 1
A prompt or query enters l0l1 at the user-to-tool boundary.
- 2
Presidio and regex rules detect PII literals.
- 3
Detected literals are anonymized before storage or forwarding.
- 4
PII columns can be annotated in returned results.
