What is Eidos

Eidos is an extensible framework for personal data management.

Most people get confused when they hear “personal data management.” They think: what data do I need to manage? I already have folders, cloud storage, note-taking apps—what more do I need?

But if you think about it, you’ll see the problem.

Your thoughts are scattered across different apps: some in your note-taking app, some in spreadsheets, some in todo lists. When you need to connect these fragments, you realize: you don’t need more apps, you need a framework that can unify all your data.

This is the problem Eidos is trying to solve.

What is Eidos?

Eidos is an extensible framework for personal data management. Notice the three key words here:

Personal: Eidos isn’t designed for teams. No collaboration features, no permission management, no complex enterprise functionality. Why? Because personal needs and enterprise needs are completely different. When you try to satisfy both, you end up with a product that satisfies neither.

Extensible: Most tools try to predict your needs. But humans are complex, and needs change. Eidos doesn’t tell you how to work—it gives you tools to define your own workflow. This extensibility isn’t a feature added later; it’s baked into the architecture from the beginning.

Data Management: Here’s an important distinction. Eidos focuses on data management, not knowledge management. Knowledge management often implies complex categorization systems and predefined workflows. Data management is more fundamental and flexible—it provides containers (documents and tables), and you decide how to use them.

Simply put, Eidos is designed for people who need a personal data management tool that’s both simple and powerful.
