What it does

You keep your sensitive personal information safe by having this agent automatically detect PII in your chat inputs and route them through secure local sanitization or compliant cloud models. It ensures full audit trails so you can meet GDPR and HIPAA standards without sacrificing performance on clean data.

How it works

When it runs: Triggered by an event · Manual · on demand
How hands-off: Assists you, you do the final step
Setup: An afternoon · about an afternoon
Works with: Code, AI Agent, Ollama Chat Model, Simple Memory, OpenRouter Chat Model

Tools that fit

Services

Code : Logic and pattern detection

Simple Memory : State management

LLM

AI Agent : Context-aware classification

Ollama Chat Model : Local LLM processing

OpenRouter Chat Model : Cloud LLM routing

Watch out for

Regex patterns can produce false positives on benign text so you must implement a secondary LLM verification step to reduce noise.
Local Ollama models may lack the nuance of cloud models for complex PII detection so benchmark them against your specific data set first.
Audit logs might inadvertently store raw PII if not carefully scrubbed before persistence so add a sanitization filter to the logging pipeline.
Latency spikes can occur when switching between local and cloud endpoints so implement circuit breakers to prevent cascading failures.

Want this running in your business?

This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.

Who it's for

Built for developers who want the busywork around code automated, not the code itself.

Ops-IT teams triaging their own internal requests get the same pattern, different queue.

Frequently asked questions

Who is this for?

developers and engineers and ops and IT teams, or anyone doing legal & compliance work who wants this handled automatically rather than manually.

How long does it take to set up?

An afternoon: plan for about an afternoon to get it running end to end.
