How they differ in practice
Both apps store Markdown, support wiki links and show backlinks. The difference is in what each one asks of you.
Bear asks almost nothing. You open it and write. Markdown renders as you type, a #tag anywhere in a note files it in the sidebar, and #tag/subtag nests it. There are no folders, no settings you need to change, and no plugins. It runs on Mac, iPhone and iPad, and Bear Web lets you reach your synced notes in a browser. The notes live in a database inside the app and export to Markdown when you ask.
Obsidian asks you to decide. Where the vault lives, how to sync it, whether to use folders or tags or both, which plugins to install. In return it runs on every desktop and mobile system, keeps every note as a file you can open with anything, and can become a task manager, a graph explorer or a research database. The files are yours whether or not Obsidian exists in ten years.
Who should pick Bear
- Every device you write on is a Mac, iPhone or iPad.
- You want to write on day one, not configure.
- You like tags more than folders.
- You want individual notes locked with a password.
Who should pick Obsidian
- You use Windows, Linux or Android, or might later.
- You want notes as plain files under your own backups.
- You want a graph of your notes and database-style queries.
- You enjoy tuning your tools, or need a plugin for a specific workflow.
The question most comparisons skip: "Bear is Apple-only"
Most comparisons say Bear only runs on Apple devices and stop there. That is true for native apps, but Bear Web runs in any major browser and opens your synced notes after an iCloud sign-in. So a Windows computer at work is no longer a hard stop for Bear, as long as your notes are synced with Bear Pro and a browser tab is acceptable.
Android still is a hard stop. There is no Bear app for Android, and a phone browser is a poor place to keep daily notes. If your phone is Android, the comparison is over and Obsidian wins.
Moving between them
Bear to Obsidian is straightforward: export all notes as Markdown or TextBundle, which the free version can do, and open the folder as a vault. Obsidian to Bear is also documented by Bear. In both directions, test a handful of notes with images, nested tags and links before moving the rest.
When neither is the right answer
If you want Markdown notes, an AI that answers from them with citations, and access from a browser or an iPhone without managing files or plugins, neither app is built for all of that. Bear has no AI. Obsidian's AI depends on which plugins you install.
Scribelet is one option in that category. Notes are Markdown with #tags, [[wikilinks]] and backlinks, they are encrypted at rest with per-desk keys, and the AI chat answers from your notes on the free plan. It has no per-note password lock and no Android app yet, so if you are Eli or Omar from the examples above, Bear or Obsidian remains the right call. The Markdown note-taking apps guide compares more of the field.
The third option: Markdown notes on the web and iPhone, with AI that cites them
Import your Obsidian vault into Scribelet or start fresh, write in Markdown with tags and wikilinks, and ask the AI chat what your notes say, with citations. Export everything as Markdown whenever you like.
