1. Note Taking Approach
Capacities: Capacities uses objects instead of plain folders. Each note is an object you can link to others. This promotes a bottom-up way to organize information, where structure emerges from your writing.
Microsoft OneNote: OneNote uses a familiar notebook metaphor. You build multiple notebooks, then split them into sections and pages. It supports free-form note taking, so you can click anywhere on a page to drop a text box and write.
2. AI Assistant
Capacities: The Capacities AI assistant sits inside your notes. This powerful assistant can draft text, summarize objects, and help you find new ideas. The AI features come with the Pro plan.
Microsoft OneNote: OneNote leans on Copilot for its AI features. The AI assistant can summarize notes and highlight key points. Copilot ties into the wider Microsoft 365 set of tools.
⚠️ Warning: Both AI assistants need a paid plan. Capacities AI needs Pro, and OneNote Copilot needs a Microsoft 365 subscription.
3. Connecting Ideas
Capacities: Contextual backlinking is where Capacities shines. It shows hidden connections between objects, much like a mind map. This helps you build a true second brain and a personal knowledge base.
Microsoft OneNote: OneNote focuses on people, not links. Multiple users can co-author one notebook in real time. Sharing notes with other OneNote users is its way of connecting ideas and work.
4. Powerful Search
Capacities: The powerful search tool helps you find notes across objects, tags, and links. Powerful search finds matches fast, even in a large knowledge base. It keeps your data within easy reach.
Microsoft OneNote: OneNote search features go further with OCR technology. Optical character recognition lets you search text inside images and handwritten notes. Custom tags help you sort and find notes too.
5. Quick Capture & Web Clipper
Capacities: Quick capture lets you jot down ideas fast. A share sheet save content option pulls in web pages and notes from other apps. Daily notes keep a running log of your thoughts.
Microsoft OneNote: The OneNote web clipper saves articles, web pages, and images to your notebooks. This browser extension can grab a full page or just an article. It is one of the better capture tools in this category.
6. Handwriting & Annotation
Capacities: Capacities does not focus on handwriting. It centers on typed, structured content and markdown notes. If you want to handwrite notes by hand, this is not its strength.
Microsoft OneNote: OneNote has strong drawing tools. You can sketch, annotate, and handwrite notes with a stylus. It also enables users to record audio and video right inside a page.
7. Calendar & Daily Notes
Capacities: Capacities has a built-in calendar and daily notes. You open a fresh page each day to capture ideas. This keeps your focus on quick capture and creative thinking.
Microsoft OneNote: OneNote has no native calendar view. Instead, it relies on Microsoft apps like Outlook for dates. You can still create to-do lists and manage tasks inside a page.
8. Voice & Audio Notes
Capacities: Capacities keeps voice features light. It is built around typed objects and links rather than audio. You can still embed media inside your notes.
Microsoft OneNote: OneNote can record audio and transcribe voice into text. This helps with lectures and meetings. It is handy when you want to write less and listen more.
9. Block Linking
Capacities: Block linking lets you reference a single block from anywhere. These links connect ideas at a granular level. It is a key part of how Capacities builds knowledge.
Microsoft OneNote: OneNote links work at the page and section level. You can link to a page, but not to a single block. Its strength is hierarchy, not granular links.
10. Custom Object Types
Capacities: Custom object types let you build your own structure. You can model people, books, projects, and more as objects. This is what makes the app feel like a studio for your mind.
Microsoft OneNote: OneNote does not use object types. You organize information with notebooks, sections, and pages. It is simpler, but less flexible for complex research.
11. Templates & Customization
Capacities: Capacities lets you create templates for objects and notes. Templates speed up repeat tasks and keep your structure clean. Dark mode and customization options round out the experience.
Microsoft OneNote: OneNote ships with custom templates for meeting notes and project plans. It also offers many customization options for fonts, colors, and tags. This makes it easy to match your style.
12. Pricing & Cost
Let’s compare the pricing plans side by side.
| Plan | Capacities | Microsoft OneNote |
|---|---|---|
| Free | $0 (limited objects) | $0 (5GB OneDrive) |
| Entry Paid | $9.99/month (Pro) | Microsoft 365 (contact) |
| Top Tier | $12.49/month (Believer) | Microsoft 365 (1TB storage) |
Capacities: The free version covers basic note taking. The Pro plan at $9.99/month adds AI features and more storage. Believer costs more and mainly supports the developer.
Microsoft OneNote: OneNote is free for most users. You only pay if you want Microsoft 365 premium features and more cloud storage. For many people, the free app is enough.

|---|---|---|
| A free, no-cost app | Microsoft OneNote | Free with no monthly uploads cap |

📝 Your Writing Style
Pick Capacities if you like to link notes and connect ideas. Pick OneNote if you prefer notebooks, pages, and handwritten notes.

Both let you start free. Test each app on a real project for a single month before you commit to a paid plan.
🛟 Support Options
Microsoft support backs OneNote with broad help docs, and the OneNote support pages cover most common questions. Capacities offers detailed documentation and an active community, and the team responds to user feedback.
🔒 Data Privacy and Security
