Open Source

We build a lot in the open. Most of our open-source work clusters around three themes: giving AI agents reliable infrastructure, connecting AI assistants to real systems, and private, local voice assistants built on Open Voice OS (OVOS) and Neon AI.

Everything below lives on our GitHub.

AI agent infrastructure #

Engram — an event-sourced memory system for AI agents. There’s no LLM in the write path, which provides fast, reliable episode storage with semantic search. An agent can remember across sessions without a model hallucinating its own history. Documentation.

Connecting AI to real systems #

These are small, dependency-light Python client libraries — each one published to PyPI and shipped three ways from a single codebase: a plain Python/CLI client, a Model Context Protocol (MCP) server, and a bundled Claude skill. Write the integration once, use it from a script, from any MCP client, or directly from Claude.

• kiwix-mcp — turns a Kiwix library into a private, local, searchable knowledge store your AI assistant can read: Wikipedia, Stack Exchange, medical and technical references, and more, all served from your own machine and fully available even when the internet isn’t. Ships as a client library, MCP server, Claude skill, and OVOS integration from one package. pip install kiwix-mcp.
• ha-http-client — a zero-dependency client for the Home Assistant REST API, with a ha-client CLI and a bundled Claude Code skill so Claude and other LLMs can control your smart home directly. pip install ha-http-client.
• music-assistant-client — a lightweight client for the Music Assistant API, with a bundled Claude skill for voice- and chat-driven media control. pip install ma-http-client.

Voice assistant tooling (OVOS / Neon) #

We maintain a family of plugins and skills for OVOS and Neon AI — the open-source, self-hosted voice assistant stack. These run on hardware you own, with no cloud dependency.

Text-to-speech plugins #

• Kokoro TTS — the 82M-parameter multilingual Kokoro model, wired up for OVOS.
• Pocket TTS — Kyutai’s lightweight, CPU-only TTS (~6× real-time on Apple Silicon, no GPU), with voice cloning.

Dialog transformers #

• Ollama dialog transformer — routes assistant responses through a local Ollama model so your voice assistant answers in its own voice, fully offline.
• Kid-friendly dialog transformer — the same idea, tuned to keep responses appropriate for children.

Skills #

• Home Assistant — control your smart home by voice through OVOS or Neon.
• Music Assistant — voice control for Music Assistant media playback.
• …and more on GitHub.
