The OneNote vs Bear comparison pits a free cross-platform canvas notebook against a beautiful Apple-only Markdown app. They solve overlapping but distinct jobs. This guide tests both and tells you which fits which user.

How We Tested

Tested over 3 weeks on macOS Sonoma, iPad Pro, iPhone 15. OneNote with Microsoft 365 Personal. Bear Pro subscription. Workloads: 30-day daily journal, 100-note research vault, lecture notebook, blog drafts.

Disclosure: we make Atlas, one of the products discussed in this post. We aim to keep evaluations honest and document our scoring criteria openly.

1. Platform Reach

OneNote runs on macOS, Windows, iPad, iPhone, Android, and web per the Microsoft 365 OneNote pricing page in May 2026. Bear is limited to Mac, iPad, and iPhone per the Bear pricing page, with no Windows, Android, or web app.

OneNote is the cross-platform choice. Bear is only viable when every serious writing device is inside the Apple ecosystem. For other Microsoft-ecosystem options, see OneNote alternatives.

2. Pricing

OneNote is free with any Microsoft account per the Microsoft 365 OneNote pricing page in May 2026. Bear has a free single-device tier, while Bear Pro costs $2.99/month or $29.99/year.

OneNote wins on free-tier breadth because the core app remains cross-platform without requiring a notes-app subscription. Bear Pro is still inexpensive if you want a polished Apple-only writing app.

3. Writing Experience

Bear has the better prose surface: Markdown typography, distraction-free editing, semantic rendering, and polished themes. OneNote is an infinite canvas for mixed media. It is excellent for lecture notes that combine text, ink, images, and audio, but it is less refined for pure prose.

Bear wins for prose-first writers. Mueller & Oppenheimer 2014 reported that note-takers who reorganize material into their own structure outperform verbatim transcribers, and a clean Markdown surface invites that reorganization.

4. Handwriting and Canvas

OneNote is much stronger for handwriting. It supports iPad and Surface ink, audio sync to ink, and an infinite canvas per the Microsoft 365 OneNote pricing page in May 2026. Bear is text-first and has limited handwriting support.

OneNote wins for ink-takers. For Apple-only ink workflows, see the Apple Notes alternatives round-up.

5. Organization

OneNote organizes notes as notebooks, sections, and pages. Bear uses a flat note list with hashtag-based organization such as #research/papers.

OneNote suits structured users, while Bear suits flat-list users. Karpicke & Roediger 2008 showed retrieval practice beats passive review, so the right structure is the one you will return to consistently.

6. Sync

OneNote uses Microsoft 365 cloud-first sync and works across all supported platforms. Bear uses Apple-only iCloud sync, and Bear Pro is required for multi-device use.

OneNote wins on cross-platform sync. Bear is fine inside Apple, but it stops being practical as soon as Windows or Android enters the workflow.

7. AI

OneNote can use Microsoft 365 Copilot at $30/month for Q&A across M365 content. Microsoft Work Trend Index 2024 reported that knowledge workers spend large blocks of the day searching and summarizing, which is the load Copilot targets.

Bear has no first-party AI. That gives OneNote the only native AI option in this comparison, but the option is expensive. For an AI-native synthesis layer, see smart notes app.

What Daily Use Looks Like

The two apps target different desks. In OneNote, a lecture starts with a fresh page in the right notebook section, the iPad picks up Pencil ink with audio recording, and the result syncs to Windows and macOS by the time you open your laptop, per the Microsoft 365 OneNote pricing page (May 2026). The cost is visual noise: the infinite canvas was built for mixed media, not for prose.

In Bear, a writing session starts with a clean Markdown buffer, hashtags carry the structure (#research/papers instead of folders), and the typography stays out of the way per Bear pricing page (May 2026). The cost is platform: no Windows, no Android, no web. Pro is $2.99/month or $29.99/year, which is reasonable for a writing-first user but pointless for anyone outside Apple.

The honest split: OneNote wins for cross-platform mixed media. Bear wins for Apple-only Markdown writers. Apple-ecosystem readers comparing Bear against the bundled default should also see Bear vs Apple Notes. There is no overlap worth fighting over. A small but useful detail per Bear pricing page (May 2026): the free tier is single-device only, so the $29.99/year unlock is essentially the cost of multi-device sync. Per Microsoft 365 OneNote pricing (May 2026), OneNote keeps the same feature set whether you pay for Microsoft 365 or stay on the free OneDrive quota, the only difference is storage (5GB free, 1TB with M365 Personal at $9.99/month).

When to Pick OneNote

You use multiple operating systems (Mac, Windows, Android). You want free notes with infinite canvas and handwriting. You live in Microsoft 365. You take mixed-media lecture notes with audio.

When to Pick Bear

You're all-in on Apple. You write long-form Markdown prose. You want beautiful typography and a distraction-free writing surface. You like hashtag-based organization. You're willing to pay $29.99/year for polish.

When to Pick Atlas

Neither does AI synthesis with source citations well. Atlas turns notes, PDFs, and research into a navigable mind map and answers cross-source questions with citations. $20/month Pro. Try Atlas.

Comparison Table

Three-Year Cost in Real Numbers

Sticker price masks the real lifetime cost. Both apps look cheap, but one is cheaper. Computed at three years from each vendor's published pricing, verified May 2026:

OneNote stays free even at scale because Microsoft amortizes the cost across the broader Microsoft 365 ecosystem. Bear is genuinely cheap at $30/year per seat but has no team-tier discount. The expensive math is OneNote-plus-Copilot: at $30/month for AI on top of $9.99/month for M365 Personal, you cross $1,440 over three years for an AI feature that Atlas at $20/month delivers for $720 total.

Privacy and Data Handling

The published privacy postures (verified May 2026):

Both tools handle encryption at rest, but Bear inherits Apple's Advanced Data Protection when you enable it on your Apple ID. OneNote's encryption is per-section with a password, which protects single notebooks but not the whole library. For healthcare, legal, or NDA-bound work where end-to-end encryption is required, Bear with ADP enabled is meaningfully stronger. For Microsoft 365-mandated environments, OneNote's compliance suite is the fit, including SOC 2, ISO 27001, and HIPAA BAA on Enterprise.

Migration In and Out

A note app is a multi-year commitment because moving notes is non-trivial. Realistic migration costs:

Microsoft offers an Evernote-to-OneNote importer for Windows. Mac users usually need a Windows VM or community Python script. Bear-to-OneNote migration requires exporting Bear notes as Markdown, then pasting them into OneNote pages because there is no native importer. A 1,000-note migration from Bear takes 4-8 hours of cleanup.

Exporting from OneNote is the hard part. OneNote stores notes in a proprietary binary format that does not export cleanly. The community tool OneNoteExporter converts to Markdown, but loses handwriting, embedded videos, and section-level passwords. Plan a full week to migrate a 5-year OneNote library out.

Bear is easier in both directions. It supports native imports from Apple Notes, Evernote ENEX, Markdown, and HTML. A 2,000-note Apple Notes library imports in 30-60 minutes with most formatting preserved. Bear also exports any selection or all notes as Markdown, PDF, HTML, or RTF, and the export is clean because notes are stored as Markdown internally.

The pattern is simple: Bear is easy to leave, and OneNote is hard. Factor this into the choice if you suspect you might switch tools in 2-3 years.

Real-World Workflows Compared

The two tools fit different work rhythms.

A typical OneNote week starts with Monday standup notes in the Work notebook, Meetings section, and today's page. Tuesday's lecture goes into the School notebook and CS101 section, with iPad Pencil annotations on the embedded slide PDF. Wednesday's brainstorm uses the infinite canvas to sketch a flowchart and add typed notes around it. Friday's review pulls notes across all three notebooks via search. Total interactions usually land around 30-50 per week, with 30-60 minutes of active note-keeping.

A typical Bear week starts with a daily note tagged #daily/2026-05-08. Tuesday adds a meeting note tagged #meeting/standup and linked from the daily note via wikilinks. Wednesday writes a 1,500-word draft tagged #blog/draft in the distraction-free editor. Friday reviews the week by searching #daily and pulling highlights into a weekly review note. Total interactions usually land around 20-30 per week, with 60-90 minutes of writing-focused work.

The split is practical. OneNote rewards capture in mixed media, while Bear rewards prose-first writing. A user who lives in OneNote and tries Bear ends up missing the canvas. A user who lives in Bear and tries OneNote ends up missing the typography. Pick by the rhythm that matches your week.

Mobile and Tablet Reality

Both tools have polished mobile apps, but the strengths differ.

OneNote on iPad is best-in-class for Apple Pencil handwriting. The audio-sync-to-ink feature recovers spoken context for any handwritten note by tapping it, and the infinite canvas works as well on iPad as on desktop. App size is about 380MB.

OneNote on iPhone has a quick-capture widget, OCR on photos, and voice memos. It is slightly slower than dedicated note apps, with an app size around 220MB. OneNote on Android is feature-complete and remains the only major Microsoft notes app with a polished Android experience, at about 210MB.

Bear on iPad has beautiful Markdown rendering with the same typography as the Mac app. Apple Pencil is supported but not the focus, and app size is about 95MB. Bear on iPhone is one of the fastest Markdown writing apps on iOS by capture speed, with cold launch to writing in under 2 seconds and an app size around 75MB.

The takeaway: OneNote is the only app that lets you ink, type, record, and clip across Mac, Windows, iOS, and Android with feature parity. Bear is the writer's app on Apple-only and is unbeatable inside that ecosystem.

Search Quality on a 5,000-Note Library

We tested both apps on a synthetic 5,000-note library mixed across plain text, handwritten ink (OneNote only), images with embedded text, and Markdown documents (Bear only). Results from May 2026:

The search split is clear. OneNote wins on multi-format search across notebooks plus handwriting OCR. Bear wins on tag-driven retrieval and document-style backlinking. Both are sufficient for typical knowledge-worker volumes. The divergence appears at 5,000+ notes when OneNote's notebook-plus-section scaffolding becomes navigation overhead, while Bear's flat-plus-hashtag model stays fast.

Plugin and Extension Ecosystems

Microsoft has slowed third-party OneNote add-in development since the 2018 transition to the modern OneNote app. The current Add-Ins gallery has roughly 50 actively maintained extensions, including Onetastic for Mac and Windows automation, Office Lens for mobile scanning, Class Notebook for educators, and Staff Notebook for managers. Most users add no extensions and rely on built-in features.

Bear has no formal plugin store. Its extensibility comes through macOS Shortcuts and x-callback-url. The Bear x-callback URL scheme lets community tools such as Drafts, Alfred, Raycast, and Hookmark round-trip notes with Bear, which covers most automation use cases. Bear 2 added a public API for tag and note manipulation, opening the door to community workflow automation, though the ecosystem remains thin compared with Obsidian.

For users wanting deep automation, neither tool matches Obsidian's plugin marketplace. OneNote's add-in story has stalled, while Bear's is intentionally narrow and Apple-native.

Community and Long-Term Viability

Two software bets carry different risk profiles. OneNote is a Microsoft product backed by a $3T-market-cap company, so the risk is feature stagnation rather than shutdown. Bear is built by Shiny Frog, a small Italian studio with about a dozen employees. The risk is the inverse: slow but consistent shipping with low organizational risk because the team is stable, but acquisition or pivot is always possible for an indie studio.

OneNote has shipped one major architecture change, the 2016 modern app, and incremental updates since. Bear shipped Bear 2 in 2023 after a multi-year wait, adding wiki-style links, math notation, and an updated rendering engine. Both apps are maintained, but neither is shipping aggressive new capabilities. The major axis of differentiation, mixed-media canvas versus Markdown typography, has not changed in 5 years and likely will not.

For a 5-10 year notes commitment, both are safe choices on the viability axis. The migration cost (Bear easy out, OneNote hard out) matters more for long-term planning than vendor risk does, because Bear's clean Markdown export means you can always leave, while OneNote's proprietary format means a future migration will be expensive regardless of whether Microsoft is still shipping it.

Final Take

Choose OneNote for free cross-platform canvas notes with handwriting. Choose Bear for Apple-only Markdown prose writing with strong typography. The decision is binary: cross-platform or Apple-only. For AI-grounded synthesis across notes plus PDFs, Atlas beats both.
