Hubbele: Open-source notetaking app for you and your agents

Hubbele has entered the eternal battlefield of note-taking apps with a big promise: it’s free, open source, and lets both people and AI helpers work from the same notes using simple text files like Markdown and web-ready HTML. Sounds neat! But the comment section was not ready to hand out applause just because another app showed up wearing the words “open source.” The loudest reaction was basically: prove it. One commenter bluntly said the landing page doesn’t explain why anyone should need “yet another notetaking app,” which is the kind of skeptical energy that instantly sets the tone online.

Still, not everyone came to throw tomatoes. One supporter said the split setup for humans and AI agents is actually a smart glimpse of where software may be headed next: people click around in a friendly interface, while bots happily chew on plain text files in the background. Another chimed in with a quieter but cutting take: if AI agents already love basic .md files sitting in project folders, why add another layer at all? And then came the drive-by comparison every new notes app dreads: “so, Obsidian?” Ouch.

There was also some side-quest chaos, with one commenter casually name-dropping tldraw and praising its free-form canvas vibes, basically saying, “Cute app, but I’m already flirting with something else.” In other words: Hubbele launched into a crowd that is curious, picky, and very, very over note-taking apps unless there’s real magic involved.
