Quick Start

Prerequisites

• Go 1.24+
• Node.js 22+
• Task
• A Mistral API key

Setup

cp srv/.env.example srv/.env    # then set MISTRAL_API_KEY
task setup                      # install dependencies
task dev                        # start API + web app

The web app runs at http://localhost:3000 and the API at http://localhost:2137.

Run task help for the full list of available commands (build, lint, test, codegen, etc.).

Limitations

• PDF-only ingestion (no other file types yet).
• Single-user MVP — no authentication.
• Local filesystem storage, no encryption at rest.
• Evidence ranges are section/page-level, not text spans.
