Stabilize every meaningful output
Run Harmonic on model responses, agent plans, tool calls, and workflow steps before they continue.
Universal AI stabilization
Add one layer between AI output and action.
Harmonic evaluates AI outputs before they reach users, tools, workflows, or agents.
It helps your system decide whether to allow, constrain, escalate, or block a continuation before unstable behavior reaches the real world.
Works with OpenAI · Claude · Gemini · LangChain · CrewAI · Custom agents · Any LLM stack
Allow, constrain, escalate, block
Keep integration clean with a bounded operational response your application can enforce immediately.
Grow into deeper governance
For higher-risk systems, expand into Admissibility Core, Execution Gateway, and Veil Runtime.
What builders get
A developer-friendly middleware layer that sits after the model and before the user-visible or execution-bound result.
- Fast API integration
- Public playground
- Usage-based pricing
- Basic logs and artifact references
- No model replacement required
What it prevents
Harmonic is designed to reduce ordinary operational drift accumulation before it becomes customer-facing or action-bound.
- Overconfident risky continuation
- Contradiction normalization
- Unsafe agent action
- Missing escalation
- Consequence-insensitive response behavior
