Obsidian vs RemNote

Obsidian is a free, local-first Markdown knowledge base with a plugin ecosystem thousands strong; RemNote is a note-taking app with spaced-repetition flashcards built into the writing itself. Here’s how they compare on pricing, platforms, linking, search, capture and collaboration — and how to decide between them.

What is Obsidian?

Obsidian stores your notes as plain Markdown files in a folder on your own device — a “vault” you can read with any text editor, back up however you like, and keep forever. On top of those files it layers backlinks, a graph view, a Canvas whiteboard, and Bases (native database views over your notes, added in 2025). The app is completely free, including for commercial use since early 2025.

Its defining feature is the community: roughly two thousand plugins extend it with everything from spaced repetition to Kanban boards to AI integrations. Official add-ons are paid — Sync ($4/month, end-to-end encrypted) keeps vaults identical across devices, and Publish ($8/month) turns notes into a public site. There’s no web app; Obsidian runs as desktop and mobile apps against your local files.

What is RemNote?

RemNote fuses notes and studying: write an outline, mark a line as a question-answer pair, and it becomes a flashcard scheduled by spaced repetition — remembering is a property of your notes, not a separate app. PDF annotation, image occlusion, and an exam scheduler round out a system clearly aimed at students, med students especially, though knowledge workers use it for durable learning too.

The free plan is generous — unlimited notes, flashcards and synced devices — with Pro at $8/month ($96/year) adding unlimited PDFs and tables, and a “Pro with AI” tier at $18/month generating cards, quizzes and summaries from PDFs and recorded lectures. It runs everywhere: web, Windows, macOS, Linux, iOS and Android, with offline support.

Where Obsidian shines

• True data ownership: plain Markdown files on your disk, readable by any app, with no account required and no lock-in.
• The largest plugin ecosystem in the category — if you want a workflow, someone has probably built it.
• Free for personal and commercial use; you only pay for optional Sync or Publish.
• Bases and Canvas add database views and visual thinking without leaving your local vault.
• End-to-end encrypted sync (as a paid add-on) for the privacy-conscious.

Worth knowing: There’s no web app, and multi-device use effectively requires paid Sync or DIY setups. Collaboration is weak — shared vaults exist but there’s no real-time co-editing. Out of the box it’s fairly bare; the power comes from configuring plugins yourself, which is a hobby in its own right. Capturing web content, newsletters or feeds means assembling extensions and plugins rather than anything built in.

Where RemNote shines

• The tightest notes-to-flashcards loop anywhere — cards are created inline as you write, not maintained separately.
• Serious study tooling: PDF annotation, image occlusion, exam scheduling.
• A genuinely usable free plan with unlimited notes and cards.
• AI tier turns PDFs and lectures into flashcards and quizzes automatically.

Worth knowing: The study focus shapes everything; as a pure PKM tool it’s busier and less elegant than dedicated rivals. Collaboration is limited to shared documents and published decks. Cloud-first and proprietary, with no end-to-end encryption.

Which should you choose?

Choose Obsidian if:

• You want your notes as local files you fully control, independent of any company’s servers.
• You enjoy tinkering and want to assemble a personalized system from plugins.
• You work offline often or in environments where cloud tools are off-limits.
• You want a free tool with no note limits.

Choose RemNote if:

• Retention is the goal — you’re studying for exams or deliberately memorizing a field.
• You annotate PDFs and lecture material heavily.
• You want notes and flashcards to be the same document.

A third option: Dexi

If what you actually want is one searchable place for notes, bookmarks, newsletters and RSS — with tags, @mentions and [[wiki links]] that organize themselves as you write, semantic search that finds ideas even when the words don’t match, and an MCP server so Claude and other AI assistants can work with your notes directly — take a look at Dexi. It’s free for up to 1,000 notes, with no app to install.
