Quick Verdict: Notion AI ($20/user/month, Business plan) wins for teams needing integrated AI and databases. Obsidian ($0 core app) dominates solo users who reject subscriptions. Evernote ($129.99/year, Personal plan) suits power searchers. OneNote is free with Microsoft 365; Roam Research ($15/month, Pro) targets networked thinkers.
- Notion AI: best for collaborative teams with database workflows
- Obsidian: best for privacy-first, plugin-driven personal vaults
- Evernote: best for OCR and cross-device sync
- Skip if: you need real-time collaboration without subscriptions, or offline-first with zero cost
- Honest limitation: Notion AI and Evernote have unpublished usage caps; heavy users report throttling after extended AI sessions
The Pricing Shift That Killed Notion AI as an Add-On
Notion changed the game in May 2025. The $10/month AI add-on disappeared. Now, full AI access (AI Agents, Ask Notion) requires the Business plan at $20/user/month. For a 6-person team, that’s $1,440/year—but unlimited AI queries, version history, and private teamspaces come with it. Free and Plus tiers get a limited AI trial only. This pricing move eliminated the “cheap AI upgrade” path and forced teams to choose: pay $20 for full AI or stay on Plus at $10/user/month and go without.
Obsidian Remains Free—And That’s the Point

Obsidian’s core desktop app costs $0 forever. No AI baked in, no subscriptions forced. The appeal is absolute: local-first storage, end-to-end encryption on your own machine, and 1,400+ community plugins. Sync Plus ($8/month annual or $10/month monthly) is optional, adding multi-device synchronization and 10 GB expandable storage. A 10-person team using only the free app pays nothing; the same team on Notion Plus pays $1,200/year. If you need AI inside Obsidian, you integrate third-party tools (ChatGPT API, Claude) yourself—no vendor lock-in.
Evernote’s 2026 Price Jump Signals Trouble
Evernote hiked Personal plan pricing to $129.99/year (up from $59.99). The Professional plan now sits at with 20 GB monthly uploads and AI Edit access. The free plan is crippled: 50 notes, one notebook, 250 MB monthly upload, one device only. For solo users deeply embedded in Evernote’s ecosystem, the search and web clipper justify the cost. For new users, the wall is steep. Evernote’s strength is handwritten note OCR and proven syncing across devices—but the price-to-feature ratio has shifted against it.
Microsoft OneNote: The Sleeper in Your Subscription
OneNote is free on its own but included in Microsoft 365 subscriptions. If you already pay for Microsoft 365 Personal ($99/year with 1 TB storage) or Home ($100/year, up to 6 users, 1 TB per person), OneNote costs you nothing incremental. It integrates tightly with Word, Excel, and Teams. New Copilot Chat features are rolling out as part of Microsoft 365 pricing increases beginning July 2026, with Microsoft 365 E3 rising from $36 to $39/user/month for enterprise. For existing Microsoft customers, it’s the path of least friction. For everyone else, there’s no standalone reason to choose it over Notion or Obsidian.
Roam Research’s $15/Month Bet on Bidirectional Linking
Roam Research charges $15/month (Pro plan) or $165/year, with a Believer tier at $500 for a 5-year commitment. The core feature is bidirectional linking—every note links to every other note automatically, surfacing unexpected connections. It’s powerful for researchers, writers, and knowledge workers who think in networks. But there’s no free tier, and the product has a steep learning curve. For casual note-takers, the cost and complexity are prohibitive. For knowledge workers, it justifies itself.
Feature Comparison: The Hidden Trade-Offs
| Tool | Price (Monthly) | AI Included | Offline Access | Collaboration |
|---|---|---|---|---|
| Notion AI (Business) | $20/user | Yes (unlimited with caps) | No | Real-time, unlimited |
| Obsidian | $0 (Sync: $8/mo) | No (DIY integrations) | Yes (local-first) | Manual sync only |
| Evernote (Personal) | $10.83/mo ($129.99/yr) | No (AI Edit in Pro only) | Yes (with Sync) | Sharing only |
| OneNote (with M365) | $8.25/mo ($99/yr) | Copilot (via M365) | Yes | Real-time, Teams native |
| Roam Research (Pro) | $15/mo | No | Yes (read-only) | Manual invite |
When Notion AI Throttles and No One Tells You
Notion’s Business plan includes “unlimited” AI, but the fine print says: “Your access to AI features can be temporarily reduced depending on your usage.” No exact limits published. Heavy users report hitting caps after 50+ AI requests in short bursts. This is the hidden cost of Notion AI—not the dollars, but the unpredictable pauses. If you’re building an automation that calls Notion AI repeatedly, you’ll hit the ceiling faster than the marketing suggests.
The Real Winner for Most Teams: OneNote + Free AI
If you’re already paying for Microsoft 365 ($99/year Personal, $100/year Home), OneNote costs you nothing. The integration with Word and Teams is seamless. Copilot features are arriving this year as part of standard Microsoft pricing. You lose advanced databases (Notion) and community plugins (Obsidian), but you also lose additional monthly fees. For teams in the Microsoft ecosystem, this is the low-friction choice.
Obsidian for the Paranoid, Notion for the Collaborative
Pick Obsidian if you demand local storage, encryption, and plugin control. Pick Notion if your team needs shared databases and AI writing assistance and you accept the $20/user/month cost. Don’t pick Evernote unless you’re already locked in to its search and OCR; the pricing no longer justifies switching in. Roam Research is niche—powerful for knowledge workers, unusable for general note-taking.
FAQ
Does Notion AI work offline? No. Notion requires internet for all AI features and core functionality. Obsidian with plugins is the offline-first alternative.
Is Obsidian Sync encrypted? Yes. End-to-end encryption by default. Notion’s data is encrypted in transit and at rest but stored on Notion’s servers.
Can I use Evernote for free in 2026? Yes, but heavily restricted: 50 notes, one notebook, 250 MB/month upload, one device. Functional for casual archiving, not for active note-taking.
Does Microsoft OneNote have AI summarization built in? Not yet in the core app. Copilot Chat is rolling out as part of Microsoft 365 starting July 2026 with pricing increases. OneNote users in Microsoft 365 will get access, but it’s not a standalone feature today.
What’s the cheapest way to get AI note-taking? Microsoft 365 Personal ($99/year) includes OneNote + Copilot Chat. Notion Business at $20/user/month requires a team. Obsidian free + ChatGPT Plus ($20/month) is $240/year solo.
For your team or workflow, evaluate whether you need real-time collaboration (Notion), privacy and control (Obsidian), or seamless Microsoft integration (OneNote). The best choice depends on what you’re willing to pay and where your data lives. Check the best AI tools to discover other productivity options that might complement your note-taking stack.
