Obsidian vs Notion 2026: Free Note-Taking Showdown
The two tools dominate note-taking in 2026 for opposite reasons. Obsidian is free, local-first and Markdown-native; Notion is a polished, cloud-collaborative workspace at $10/month. Here is an honest side-by-side, who wins what, and which to pick for your use case.
TL;DR
Choose Obsidian if
You want free, private, offline-first notes you own forever — especially for personal knowledge management, research or student use.
Choose Notion if
You need real-time collaboration, native databases, a team wiki or a zero-setup workspace — and you are happy to pay $10/month for it.

Tally: Obsidian 7 · Notion 5 · Tie 1. The tally is a rough guide — the use-case breakdown below matters more than the count.

FAQs
Is Obsidian really free?
Yes for personal use. The desktop and mobile apps are free forever with no feature limits on the core product. The two paid add-ons are Obsidian Sync ($4/month) for end-to-end-encrypted multi-device sync, and Obsidian Publish ($8/month) for hosting a public site from your vault. Neither is required — you can self-host sync via Git, iCloud or Syncthing for nothing.
Can Notion replace Obsidian for personal notes?
It can, but you give up three things Obsidian owners care about: your data lives in Notion's cloud rather than on your machine, the offline experience is weak, and export back to plain Markdown is imperfect. If those do not matter to you, Notion's polish and databases are genuinely better. If they do, Obsidian wins.
Which is better for a second brain / Zettelkasten?
Obsidian, clearly. The combination of local Markdown files, bidirectional links, backlinks panel, graph view and a deep plugin ecosystem is purpose-built for linked-note thinking. Notion supports links and databases but its block model and cloud-first design fight the Zettelkasten workflow.
How much do you save by choosing Obsidian over Notion?
For a solo user on Notion Plus ($10/month), switching to Obsidian saves $120/year directly, plus you skip the Notion AI add-on ($8-10/month) by bringing your own API key via a plugin. For a team of 10 on Notion Business ($18/seat/month), that is $2,160/year — but Notion's collaboration is worth paying for if your team actually uses it.
Can I move from Notion to Obsidian (or back)?
Notion to Obsidian: export each workspace to Markdown/CSV, then open the folder as a vault. Some formatting and database structure is lost in the conversion. Obsidian to Notion: import Markdown via Notion's importer; links convert imperfectly. Neither direction is one-click clean, but Markdown export from Obsidian is far more reliable because the source is already plain text.
Which has better AI features in 2026?
Notion AI is more polished out of the box — search, summarisation, writing and database autofill are built in, priced as an add-on (~$8-10/month per seat). Obsidian's AI is plugin-based: you bring your own API key (OpenAI, Anthropic, local models) and choose plugins like Smart Connections or Copilot. Notion wins on convenience; Obsidian wins on cost and model choice.
