# Docex

> Agent-first vision and OCR infrastructure for evidence-backed image and PDF runs.

# Docex

> **Agent-first vision and OCR infrastructure.** Route any image or PDF through evidence capture, provider fallback, structured output, and cost visibility.

Docex accepts a file (image or PDF) plus a user prompt, classifies the task, selects an execution strategy, runs it through one or more AI providers, and returns structured JSON with confidence scores and usage-based billing.

  <Card title="Provider abstraction" icon="route">
    Automatic routing across OpenRouter, Mistral OCR, and mock providers with fallback if a provider fails.
