The short version

  • Each has a real cost: Brain.fm monthly plan at $14.99/month significantly more expensive per unit than annual plan ($8.33/month equivalent); Microsoft OneNote notes live in a proprietary notebook format on OneDrive or SharePoint and the only exports are a OneNote file, a PDF or a Word document, produced section by section, so a large notebook is effectively unmovable to any other tool.
  • They diverge on capability: Brain.fm covers Neuroscience-designed music, Microsoft OneNote covers Free-form page canvas.
  • Prices and features above were last checked on 30 August 2026.

Microsoft OneNote

  • Handwritten notes on a pen tablet that you still need to find months later by searching for a word you wrote.not Brain.fm
  • Lecture or meeting notes where a recording needs to line up with what you were typing at the time.not Brain.fm
  • A team already inside Microsoft 365 that needs a shared notebook without buying anything or seeking approval.not Brain.fm
  • Collecting mixed material such as screenshots, clippings and sketches on one page, where a document editor would force a linear structure.not Brain.fm

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Brain.fm

  • Monthly plan at $14.99/month significantly more expensive per unit than annual plan ($8.33/month equivalent)
  • ADHD mode available only with active subscription; no trial access to specialised features
  • No offline mode documented; requires internet connectivity for audio delivery
  • Content library composition not published (proprietary vs. licensed music distinction unclear)

Microsoft OneNote

  • Notes live in a proprietary notebook format on OneDrive or SharePoint and the only exports are a OneNote file, a PDF or a Word document, produced section by section, so a large notebook is effectively unmovable to any other tool.
  • Personal notebooks consume OneDrive quota, which is 5 GB on a free Microsoft account, so a notebook full of scans, images and recordings quietly exhausts the whole account including the space Outlook needs for mail.
  • Sync happens at section level and conflicts are resolved by placing both versions on the page, so simultaneous edits to a large or media-heavy section produce duplicated content that somebody has to merge by hand.
  • Search behaves differently across clients, so what the Windows desktop app finds inside handwriting, images and attachments is not necessarily what the browser or mobile version finds, and the same query gives different answers on different devices.
  • There is no relational structure, no database and no properties, so anything that needs a table of records with fields has to be maintained by hand or moved elsewhere, and OneNote's own tables cannot be queried or filtered.

Section by section as a OneNote file, a PDF or a Word document. A OneNote package preserves a whole notebook but only for another copy of OneNote. Third-party converters exist and the page layout usually does not survive them.

Microsoft OneNote: Which version should I install?

Microsoft consolidated onto a single OneNote application on Windows after retiring the Store version, so install the one distributed with Microsoft 365 rather than looking for an alternative.
