OpenHuman
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.
See https://developer.openhuman.ai/
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.
