# Welcome to Alethia AI

> The simplest way to test whether a Large Language Model is safe — and prove it.

## What is Alethia AI?

Alethia AI helps you answer one important question:

> **"Does this AI model respond safely when people try to misuse it?"**

You bring an LLM (like GPT-4o, Claude, Gemini, or your own custom model). Alethia sends it a library of carefully designed prompts that try to push it toward unsafe answers. Then a panel of independent AI judges grades each response. Finally, you get clear results, dashboards, and audit-ready reports.

If your organization has to comply with the **EU AI Act**, Alethia also gives you the full risk management workflow you need — classification, risk register, mitigations, and exportable compliance reports.

## Who is Alethia for?

Alethia is built for teams who need to **trust the AI they ship** — and prove that trust to regulators, customers, and leadership.

## What can I do with Alethia?

* **Test any LLM** — OpenAI, Anthropic, Google, Mistral, DeepSeek, or your own custom endpoint.
* **Use 137 ready-made prompts** across 18 safety categories — or upload your own.
* **Get verdicts you can trust** — three independent AI judges grade every response.
* **Override anything** — humans always have the final say (and it's all logged).
* **Schedule recurring tests** — catch regressions automatically.
* **Compare models side by side** — "Is GPT-4o safer than Claude for our use case?"
* **Manage EU AI Act risks** — classification, register, assessments, mitigations, and reports.
