## Best for

People who keep notes as plain Markdown files and want agents to read and write them alongside them.

## Why it deserves attention

Hubble stays close to the file system: notes are ordinary Markdown, HTML files can become custom views of your notes, and edits made by an agent show up as soon as the file changes. It organizes everything around a folder-based library with tags and quick capture, and runs on macOS, Windows, and Linux. It is MIT-licensed, free, and currently at version 0.3 with about 1,500 GitHub stars, so expect a young app with rough edges rather than a full Notion-style database product.
