The short version

  • Each has a real cost: LibreOffice real-time collaborative editing is far behind Microsoft 365 and Google Workspace, and for teams who co-edit this alone usually decides the question; RemNote the free plan is unlimited on notes and flashcards but meters exactly what a student needs, at three annotated PDFs, five image-occlusion images and one handwritten document, so the trigger to pay arrives in the first week of a term rather than after a year.
  • They diverge on capability: LibreOffice covers Full suite, RemNote covers Notes and cards in one document.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

LibreOffice

  • Real-time collaborative editing is far behind Microsoft 365 and Google Workspace, and for teams who co-edit this alone usually decides the question
  • Mobile support is weak, which is disqualifying for a workforce that reviews documents on phones
  • Complex Microsoft Office documents still lose formatting in transit, so exchange-heavy workflows need testing with real files
  • Central policy management, conditional access and audit tooling are thin against the commercial suites
  • Advanced spreadsheet work is where the gap with Excel is widest, and it affects exactly the users least willing to change

RemNote

  • The free plan is unlimited on notes and flashcards but meters exactly what a student needs, at three annotated PDFs, five image-occlusion images and one handwritten document, so the trigger to pay arrives in the first week of a term rather than after a year.
  • Notes can be exported as text, but the review history and scheduling state cannot be carried into another spaced repetition system, and after a year of study that scheduling state is the real asset rather than the notes.
  • Knowledge bases built over several years slow the application down, and because the method depends on daily reviews, the performance problems arrive exactly when you have the most invested and the least appetite to move.
  • AI features are metered in credits at a hundred a month on the free plan, and the tier that makes them usable costs more than double the standard paid plan, so the AI is effectively a second purchase rather than a feature of the product.
  • It is a small independent vendor serving individual students, with no organisational sales underwriting it, so anyone committing several years of study material is betting on the company's continuity without an institutional customer base as a safety net.

Answered from the vendors’ own pages

LibreOffice: Is LibreOffice really free for business use?

Yes. It is open source with no per-seat licence and no restriction on commercial use. The Document Foundation is funded by donations and sponsors.

RemNote: How is it different from Anki?

Anki is a flashcard system you feed, free and open with an enormous library of shared decks and a long record of stability. RemNote generates the cards from notes you are already writing, which saves the copying step but ties the cards to one vendor.

LibreOffice: Does it have AI features?

No. The 26.8 release states it contains no generative AI, that documents are not transmitted to remote services, and that no component requires network access.

RemNote: Does it work offline?

An offline mode is offered. Sync conflicts across devices are the usual caveat, so test it with your own workflow before depending on it during an exam period.

LibreOffice: Can it open Microsoft Office files?

Yes, and save back to them. Round-tripping complex documents is imperfect between any two suites, so test with your own files before committing to an exchange-heavy workflow.

RemNote: What does the free plan actually restrict?

Not notes or flashcards, which are unlimited, and not the number of devices. It restricts annotated PDFs, image occlusion images, handwritten documents, daily uploads and AI credits.

LibreOffice: Why do governments use it?

Two reasons: no per-seat cost at scale, and OpenDocument is an ISO standard implemented by more than one vendor, which matters for archives that must stay readable after a vendor relationship ends.

RemNote: Can I get my material out?

Notes export in text form. The scheduling state and review history do not transfer, so leaving means keeping your notes and restarting the review cycle from nothing.

LibreOffice: What is the biggest reason not to use it?

Collaborative editing. If several people work on the same document simultaneously, Microsoft 365 and Google Workspace are substantially better and that gap is not closing.
