Overview

OpenHuman by TinyHumans is an open-source agentic desktop assistant for macOS that aims to know everything about you while keeping your data private. It builds a local-first memory tree — compressed Markdown stored in SQLite as an Obsidian-style wiki — that can hold up to a billion tokens of context, and auto-fetches from your connected tools every 20 minutes so it gains your context in minutes, not weeks. A local LLM handles low-level work like summarizing and tooling to keep private data off the cloud, while intelligent model routing picks reasoning, fast, or vision models through a single subscription that covers 30+ providers. Connect Gmail, Notion, GitHub, Slack, Calendar, and 100+ more integrations with one-click OAuth, and use native tools for web search, file system access, git, voice, and code. A desktop mascot speaks, reacts, and can even join video meetings.

Pricing: Free, open source | Subscription for managed models

Architecture: Apple Silicon, Intel
