Comparison
The short version
OneNote is a freeform digital notebook: infinite canvas, sections, ink, and deep Microsoft 365 integration. Great for handwriting, meeting notes alongside Outlook, and anything that wants flexible page layout. If you live in the Microsoft ecosystem at work, it is the path of least resistance.
Mindly is not a whiteboard. It's a structured second brain with AI organization and a built-in mind map. One shortcut for capture, cards instead of pages, and connections that emerge automatically across everything you save.
Students who annotate slides in OneNote often pair it with Mindly as a "thinking layer" for synthesis and idea review. The two play different roles: OneNote for the lecture, Mindly for the week of revision that comes after.
The clearest decision point is whether your day is Microsoft-shaped. If meetings live in Outlook, files in SharePoint, and chat in Teams, OneNote slots in with zero friction. If your day is Mac-shaped, with Apple-native apps and a preference for local libraries, Mindly is the more natural fit.
Cost is also worth naming. OneNote is free with a Microsoft account; tighter integrations come with a Microsoft 365 subscription. Mindly is a paid Pro tier on top of a free base. Different bets on what value to bundle, so pick the one whose bundle matches the work you already do.
Microsoft OneNote at a glance: OneNote excels when you want handwriting, meeting notes beside Outlook, and a flexible page layout inside the Microsoft ecosystem. Strong on iPad with the Pencil, and the only major notebook still pushing freeform canvas as the first-class layout.
The context
OneNote has real strengths, and a fair comparison should start with them. It is free with a Microsoft account, its freeform canvas takes ink, images, and text anywhere on the page, and inside a Microsoft workplace it connects to Outlook, Teams, and SharePoint with no friction at all. For meeting notes that live next to the calendar invite, very little beats it.
The friction shows up over time, and on the Mac. A freeform canvas is wonderful to write on and hard to search later: content floats in containers across pages, sections, and notebooks until finding a specific thing means remembering where you put it. And OneNote for Mac has long trailed its Windows sibling in features and polish, which stings when the Mac is your main machine.
Mindly is the Mac-shaped answer to both problems. It is native to macOS, so nothing about it is a port, and it trades the freeform canvas for structured items that organize themselves. One shortcut captures notes, links, files, PDFs, screenshots, and voice, AI tags and summarizes each save, and semantic search finds things by meaning rather than by remembered location.

Beyond the table
OneNote's canvas is its identity: type anywhere, drop an image next to a sketch, let a page grow in every direction. That freedom is great during a meeting and expensive afterward, because a canvas has no inherent structure for a tool, or a future you, to work with. Notebooks multiply, sections nest, and the whereabouts of any given thought becomes an act of memory. Mindly stores discrete items instead: each note, link, PDF, or voice memo is its own object with AI-applied tags, a summary, and links to related items, so the library stays navigable at any size.
Capturing into OneNote on a Mac means going to OneNote: open the app, find the notebook, find the section, pick or create a page, then paste. Each step is small, and together they are why so many stray thoughts never make it in. Mindly's capture is one keystroke from any app. Press ⌘M, drop in the text, link, file, screenshot, or a voice note, and return to what you were doing. The item is tagged, summarized, and connected before you would have finished choosing a section.
OneNote's search is better than its reputation: it reads text in images and does well with handwriting, a real strength for ink-heavy notebooks. But it is keyword search over freeform pages, so it finds words rather than meaning, and results drop you onto a sprawling canvas where the match may be anywhere. Mindly indexes everything semantically. Voice memos are transcribed, screenshots and PDFs are read with OCR, and a plain-language query like "notes from the kitchen renovation quotes" pulls the right items across formats, each one a self-contained card rather than a spot on a canvas.
OneNote is at its best on Windows, and Microsoft's priorities have generally followed its enterprise base there. The Mac app is serviceable but has long been the thinner sibling, with features arriving later or not at all. If you live on a Mac, you are effectively using a guest. Mindly runs only on macOS 14 and later, which is a limitation and a focus at once: the shortcut, the windows, the notifications, and the performance are all built for the machine you actually use, not adapted for it.
OneNote notebooks live in OneDrive or SharePoint under a Microsoft account, and for work notebooks, under your organization's policies too. Leave the company or lose the tenant, and notebooks can go with it; the custody is real but conditional. Mindly keeps your library in a folder on your Mac, works without any account, and exports to standard formats when you want your data elsewhere. AI runs over encrypted channels and your content is not retained after the request. For personal knowledge you expect to keep for a decade, unconditional custody is the safer default.

Making the move
OneNote is the awkward one to leave, and it is fair to say so: there is no clean bulk export to a portable format. Sections can be exported as files in some versions, and PDF export or copy-paste covers the rest. Treat that constraint as a filter, and move only what you would miss.
Common questions
It depends on what you use OneNote for. For handwriting on an iPad, GoodNotes or Notability are closer fits. For shared team notebooks, staying inside Microsoft is usually right. If OneNote is your personal everything-bucket and the Mac app's limits are the problem, Mindly is a native macOS second brain that captures the same range of material and organizes it automatically instead of leaving it on a canvas.
Awkwardly, and it is fair to know that going in. Depending on the version, you can export pages or sections to PDF, or export section files that mostly only OneNote can read; there is no clean bulk export to a portable format. For a move, the practical path is PDF export or copy-paste for the pages that matter, and leaving the rest archived in place.
It works, but OneNote on Mac has long been the thinner version of the Windows app, with features arriving later or not at all. That is a reasonable trade if your workplace runs on Microsoft 365 and the notebook is shared. For personal notes on a machine you chose because it is a Mac, a native tool tends to fit better, which is the gap Mindly is built for.
For capturing and finding them afterwards, yes: press ⌘M, type or dictate, and the note is tagged, summarized, and searchable by meaning, with voice memos transcribed. What Mindly does not do is OneNote's Outlook integration, so the invite and the note will not be linked objects. If notes belong to your employer's Microsoft tenant, keeping work notes in OneNote and personal knowledge in Mindly is a clean split.
No. Mindly is macOS only, requiring macOS 14 or later, with no Windows, iPad, or web version. If you rely on inking on an iPad or a shared notebook opened from a Windows desktop, OneNote keeps that advantage. Mindly's bet is the opposite one: go deep on a single platform so capture, search, and notifications feel native on the Mac.
No. Mindly is not built around ink, and OneNote with a stylus remains genuinely good at it. What Mindly does instead is read what you bring it: screenshots and PDFs go through OCR, voice memos are transcribed, and everything becomes searchable text. If your handwritten pages end up as images or PDFs, Mindly can index them, but writing by hand is not the workflow it is designed for.
If this comparison resonates, try Mindly on your Mac. One shortcut for mixed saves, a library that lives on your device, and AI that organizes everything automatically.
