  • They diverge on capability: Canary Mail covers AI Copilot, LibreOffice covers Full suite.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.
