Local document agent for accurate, cited answers.

Heph

A local document agent for accurate, cited answers from your files.

Heph is built around normal folders. An armory keeps your documents in materials/ and Heph-owned local state in .harness/, so the armory stays portable and inspectable.

What Heph Does

• Answers from local armory materials with verifiable citations.
• Indexes PDFs, Office documents, notes, code, and other supported text sources.
• Opens retrieved evidence and source context from the terminal UI.
• Keeps chats, retrieval indexes, memory, traces, and usage snapshots in local armory state.
• Lets provider and model choices remain configurable instead of hardcoded.
• Exposes a Python SDK for native apps, GUI shells, and automation.

Install

uv tool install heph@latest

You can also install with pip:

pip install heph

Heph requires Python 3.13 or newer.

Update

heph update
heph --version

Quick Start

heph armory init my-notes
cp ~/Downloads/example.pdf ~/.armories/my-notes/materials/
heph my-notes

Inside Heph, ask questions about your materials. When Heph cites evidence, use the Evidence panel or /evidence command to inspect the cited source context.

Trust Model

Heph is local-first beta software. Materials remain in your armory, and memory is scoped to that armory unless you explicitly choose to move or share state. Analytics and crash reporting are opt-in from /settings.

Model providers may receive prompt content when selected for a turn. Review Trust and ownership and Privacy for the full data, cache, prompt, and compute contract.

Development

The public package bundles the Heph CLI, harness, AI runtime, interfaces, and extension contracts into one installable distribution. Repository development still keeps those layers separated under packages/.
