Is Obsidian really free?

Yes. Obsidian's core app is completely free for personal use with no limits on notes, storage, or features. You only pay for optional add-ons: Sync ($4-5/month for cross-device syncing) and Publish ($8-10/month for publishing notes as a website). Commercial use requires a $50/user/year license.

Is Notion cheaper than Obsidian?

No. Obsidian is free for personal use while Notion costs $10/user/month (Plus plan). However, Notion includes real-time collaboration, web access, and team features that Obsidian lacks. For solo users, Obsidian is free. For teams, Notion's collaboration features justify the cost.

Is Roam Research worth $15/month?

Roam Research is worth it only if you heavily use its unique bi-directional linking and block-level references. For most users, Obsidian (free) offers similar linking features with better performance and a larger plugin ecosystem. Roam's $15/month ($8.25/mo annual) is hard to justify when Obsidian does 90% of it for free.

Can Obsidian replace Notion for teams?

Not really. Obsidian is a local-first personal knowledge tool. It has no real-time collaboration, no shared workspaces, no web access, and no team permissions. Notion is built for teams with shared databases, real-time editing, and team wikis. They serve different purposes despite some feature overlap.

What is the best free note-taking app in 2026?

Obsidian is the best free note-taking app for power users who want local storage, markdown files, and extensive customization. Notion Free is better for teams that need collaboration. Apple Notes is best for simple personal use in the Apple ecosystem. Google Keep is best for quick notes across devices.

Pricing Plans at a Glance (2026)

Tier	Notion	Obsidian	Roam Research
Free	Yes (unlimited pages, 10 guests)	Yes (full app, unlimited notes)	No (31-day trial only)
Personal/Standard	$10/user/mo (Plus)	$0 (free for personal use)	$15/mo monthly / $8.25/mo annual
Sync/Collaboration	Included in all plans	$4-5/mo (Sync add-on)	Included

Enterprise	Custom pricing	N/A	$500 for 5 years (Believer)
Publish (website)	N/A (use Notion sites)	$8-10/mo (Publish add-on)	N/A

Obsidian's hidden cost: While Obsidian is free, you need the Sync add-on ($4-5/month) to use it across multiple devices. Without Sync, your notes stay on one device. For a team of 10, the commercial license ($50/user/year) plus Sync adds up to ~$100/user/year. Still cheaper than Notion, but not completely free for teams.

Who Should Use What?

Solo Knowledge Worker: Obsidian (Free)

Obsidian is the clear winner for personal knowledge management. It is free, stores data locally as markdown files you own forever, has 1,000+ plugins, and the bi-directional linking is excellent. The learning curve is worth it if you plan to build a large personal knowledge base. Add Sync ($5/mo) if you need cross-device access.

Startup Team (5-25 people): Notion ($10/user/mo)

Notion is the best team knowledge tool. Real-time collaboration, shared databases, team wikis, and project management in one tool. The $10/user/month price includes everything a team needs. Obsidian has no team features, and Roam's collaboration is basic. For teams, Notion is worth every dollar.

Academic Researcher: Roam Research ($8.25/mo) or Obsidian (Free)

Roam's block-level references are genuinely unique for academic work where you need to reference specific paragraphs across hundreds of papers. But Obsidian's free Dataview plugin offers similar capabilities. Try Obsidian first (free). Only pay for Roam if you specifically need block references that Obsidian cannot replicate.

Privacy-Conscious User: Obsidian (Free)

Obsidian stores everything locally as plain markdown files. No cloud, no servers, no data mining. If privacy matters, Obsidian is the only choice here. Notion and Roam both store your data on their servers.

The Hidden Costs Nobody Mentions

Notion's Collaboration Tax

Notion charges per user. A 25-person team pays $3,000/year on the Plus plan. But not everyone needs full access. Consider: do your 25 people all need to edit, or do 15 of them just need to read? Notion's guest feature (free, limited) can reduce costs for view-only users.

Obsidian's Sync Requirement

Obsidian is free, but if you use multiple devices (laptop + phone), you need Sync at $5/month. That is $60/year. Notion includes sync in all plans. Roam is cloud-based and always synced. Factor this into your comparison if cross-device access matters.

Roam's Uncertain Future

Roam Research is a small company with a niche product. The $500 Believer plan (5 years) is a bet that Roam will exist in 5 years. Obsidian and Notion have larger communities and more stable funding. Consider this risk when committing to Roam for your entire knowledge base.
