The short version

  • Each has a real cost: Canary Mail pGP encryption only protects a message if the recipient also supports and uses PGP, so most everyday mail to non-technical contacts stays unencrypted regardless.; 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: Canary Mail covers AI Copilot, RemNote covers Notes and cards in one document.
  • 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.

Canary Mail

  • PGP encryption only protects a message if the recipient also supports and uses PGP, so most everyday mail to non-technical contacts stays unencrypted regardless.
  • Team and shared-inbox features are minimal compared with Spark or dedicated tools, so it does not suit a support team out of the box.
  • The lifetime purchase price and terms have shifted over past versions, and buyers should confirm current lifetime pricing directly before assuming it still applies.
  • AI features still require sending thread content to a processing service to generate drafts and summaries, so the privacy story is stronger for encryption than for the AI layer itself.
  • Windows and Android apps have historically received updates later than the macOS and iOS versions.

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

Canary Mail: Does Canary Mail host my email?

No, it is a client over Gmail, Outlook, iCloud or IMAP accounts you already have.

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.

Canary Mail: Is the lifetime licence still available?

Canary has offered a one-time lifetime purchase alongside its subscriptions; check current pricing on their site as terms have changed over time.

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.

Canary Mail: Does PGP encryption work automatically?

Only between users who both have PGP set up; it does not encrypt mail to recipients without it.

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.

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.
