OpenHuman

by TinyHumans.ai

An open-source personal AI assistant built in Rust/Tauri that learns your context from day one — your AI assistant already knows who you are when you need it.

Features

  • 118+ Third-Party Integrations — One-click OAuth connections to Gmail, GitHub, Slack, Notion, Stripe, Google Calendar, Google Drive, Linear, Jira, and more
  • Autonomous Data Polling — Fetches new emails, calendar events, code commits, and document edits every 20 minutes without manual configuration
  • Memory Tree Architecture — Hierarchical summarization pipeline that chunks data (~3,000 tokens), scores relevance, and builds deterministic memory structures
  • Obsidian Compatibility — Memory data stored as both SQLite and markdown files compatible with Obsidian for note-taking workflows
  • Built-in Tools — Web search, web fetch, filesystem access, Git workflows, code search (grep-like), speech-to-text, text-to-speech, token compression
  • Cross-Platform Desktop — Built on Tauri (Rust) instead of Electron for smaller, faster, more secure applications
  • Local AI Support — Optional local model integration for on-device processing
  • Open Source — GNU GPL3 license, community-driven development

Superpowers

OpenHuman inverts the typical AI assistant playbook: instead of learning about you gradually, it reads your personal data first. The three-stage pipeline (connection → fetch → memory) automatically ingests context from your connected services, builds a hierarchical memory structure, and makes that context available to your assistant whenever you interact with it.

Who this is for:

  • Developers wanting a privacy-first, open-source personal AI assistant
  • Users who want their AI to understand their work context without manual setup
  • Teams that prefer local-first architecture with optional cloud integration
  • People interested in combining AI assistants with personal knowledge management (PKM)

What you gain:

  • Personal AI assistants with immediate contextual awareness of your email, calendar, code, documents, and projects
  • Privacy-preserving architecture (data stays on your machine)
  • Extensible framework for building custom assistant behaviors
  • Integration with your existing knowledge management system (Obsidian)

Status & Community

Currently in early alpha with active development. The project is trending on GitHub and has an active Discord community. Built in Rust with Tauri for production-quality performance.
