The short version

  • Each has a real cost: 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.; Spark Mail several sync features route mail metadata and, for some features, credentials through Readdle servers, which is a materially different trust model from a local-only IMAP client.
  • They diverge on capability: RemNote covers Notes and cards in one document, Spark Mail covers Smart Inbox.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

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.

Spark Mail

  • Several sync features route mail metadata and, for some features, credentials through Readdle servers, which is a materially different trust model from a local-only IMAP client.
  • It is a client over accounts you still pay for elsewhere, so the total cost is Spark plus whatever Gmail, Outlook or Fastmail plan you already hold.
  • The free tier lacks AI Copilot and summaries, so the features it is best known for sit behind the paid plan.
  • Team features are basic next to dedicated shared-inbox tools like Front or Help Scout, so a support team scaling past a few agents will likely outgrow it.
  • Windows and Android versions have historically lagged the macOS and iOS apps in feature parity.

Answered from the vendors’ own pages

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.

Spark Mail: Does Spark host my email?

No. It is a client that connects to Gmail, Outlook, iCloud or any IMAP account; you still need a mail host.

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.

Spark Mail: Does Spark store my email credentials on its servers?

For some features, including cross-device snooze and send-later sync, yes. It is part of how those features stay consistent across devices.

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.

Spark Mail: Is there a one-time purchase option?

No, Spark is subscription only for individuals and teams; the base client is free but AI and unlimited scheduling need Premium.

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.
