I built TrustLayer — an open-source trust layer for every AI tool you use

I've been using 3+ AI tools daily — Claude, GPT-4, Ollama locally — and I kept running into the same problems:

No way to verify outputs when AI tools disagree with each other
No idea what I'm spending across multiple providers
No unified view of what's running locally vs in the cloud

So I built TrustLayer — an open-source trust layer that sits between you and every AI tool you use.

What it does

Verification Engine — Every AI output gets a 0-100 trust score. Detects overconfident language, hallucination patterns, and unverified claims. Uses your local Ollama to cross-check suspicious claims.

OpenAI-Compatible Proxy — Set one environment variable and all your tools route through TrustLayer:

export OPENAI_BASE_URL=http://localhost:8000/v1

Now Claude Code, Cursor, Aider, and your own scripts all flow through TrustLayer for logging and cost tracking — with zero code changes.

Cost Tracking — See exactly what you're spending per provider, per model, per day. Set budgets. Get alerts.

Smart Routing — Automatically route simple tasks to cheaper models. TrustLayer classifies your prompts and saves you money by not sending "what's 2+2" to GPT-4o when GPT-4o-mini handles it fine.

CLI Tools Detected — Auto-detects Ollama, Claude Code, Gemini CLI, Aider on your machine. Shows them alongside your API providers.

Quick start

pip install trustlayer-ai
trustlayer server

That's it. No account needed. No config files. Ollama gets auto-detected if it's running.
