Make your agentsfollow rules
AI agents ignore your rules. Your pricing logic, your refund policies, your escalation triggers, your compliance requirements. Open Bias catches and fixes violations before they reach your users.
Everything between your
agent and a bad decision.
Policy Enforcement
Define business rules in plain English. Pricing limits, compliance requirements, data handling policies — enforced automatically across every AI interaction. No rule gets ignored, no matter how many you add.
Real-Time Protection
Violations are caught and corrected before they reach customers. Block unauthorized discounts, prevent data leaks, enforce approval workflows — all in real time, not after the fact.
Full Audit Trail
Every AI decision is logged with rule-by-rule pass/fail results. Meet compliance requirements with complete traceability. Know exactly what your agents said, why, and which policies applied.
Zero Integration Overhead
Drop-in proxy that works with any LLM provider. No code changes, no vendor lock-in, no latency impact. Your team ships AI features while Open Bias handles the guardrails.
How we think about enforcement.
Most guardrails bolt on after something breaks. Open Bias is built around the full failure lifecycle — from detection to intervention.
WITHOUT GUARDRAILS
vAI agents don't follow instructions reliably. They hallucinate, skip steps, and drift from policy — especially across long conversations and edge cases.
MONITORING GAP
vYour agents are running hundreds of sessions simultaneously. Some follow policy. Some don't. Without enforcement, you find out from a customer complaint — not a dashboard.
PROXY
vIt sits between your app and the LLM provider. In between, every call is evaluated, logged, and — if needed — corrected. Zero changes to your agent code.
ENGINE
vNot every rule needs the same level of scrutiny. Hard limits like discount caps get instant, deterministic checks. Nuanced policies like tone of voice get AI-powered judgment. You pick the right tool for each rule — and only pay for what you need.
INTERVENE
vDetection without action is just monitoring. When a violation is caught, Open Bias automatically corrects the agent — blocking harmful responses, steering the conversation back on policy, or fixing the output before it reaches your customer.
How it works
Deviation detection
Watch an agent drift from policy compliance in real time — and see the guardrails kick in.
Performance you
can measure.
Works with everything
you already use.
Connects to every major LLM provider, agent framework, and observability tool.
Ship policies,
not workarounds.
Define rules in RULES.md. Point your client at the proxy. Open Bias enforces policy on every request — zero config, zero latency.
Zero config startup
Starter RULES.md and default evaluator out of the box.
Zero latency
Async eval by default. Critical violations blocked sync.
Provider agnostic
Anthropic, OpenAI, Google, Mistral, and more.
Multiple engines
Judge LLM, NeMo, FSM — pick per concern.
