Extensible offline-first personal data management powered by SQLite
Transform SQLite into a personal pocket database with Notion-like documents, offline-first architecture, AI integration, and powerful extensibility through custom blocks and scripts.

Eidos is an extensible framework that transforms SQLite into a comprehensive personal data management system. Combining the familiarity of Notion-like documents and databases with the power of local-first architecture, Eidos gives you complete control over your information without internet dependency.
Everything runs on your local machine. Your data stays in SQLite format—open, accessible, and blazing fast. Deep LLM integration enables AI-powered translation, summarization, and intelligent interactions directly within your workspace, while maintaining full data sovereignty.
Eidos features a powerful extension system that lets you customize every aspect of your workflow. Build UI blocks for tailored data visualization, write TypeScript/JavaScript/Python scripts for complex data processing, or use AI to generate extensions on the fly. The framework adapts to your needs, whether you're organizing personal notes, managing projects, or building custom knowledge bases.
Available as both desktop and PWA applications, Eidos is currently in active development under AGPL-3.0 license. While functional for exploration, it's not yet recommended for production use.
When teams consider Eidos, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Personal Knowledge Base
Organize notes, documents, and research locally with AI-powered summarization and search, maintaining complete privacy and offline access.
Custom Project Management
Build tailored project tracking systems using custom blocks and scripts, with data stored in accessible SQLite format for integration with other tools.
Offline Research Repository
Collect and analyze research materials without internet dependency, leveraging LLM features for translation and content analysis on local data.
Developer Documentation Hub
Create extensible documentation systems with custom UI components and automated data processing scripts, all running locally for maximum speed.
No. Eidos is offline-first and runs entirely on your local machine. All data is stored locally in SQLite, ensuring you can access and work with your information without internet connectivity.
While Eidos runs offline, AI features require LLM integration which typically connects to external services. The framework is designed to deeply integrate these capabilities while keeping your core data local.
Yes. All data is stored in open SQLite format, giving you direct access to your information through any SQLite-compatible tool or library.
Not yet. Eidos is under active development and the maintainers do not recommend it for production use at this time. It's suitable for exploration and testing.
Eidos supports TypeScript, JavaScript, and Python for writing scripts. You can also build custom UI blocks and use AI to generate extension code.
