The short version

  • Each has a real cost: Signal signal must be installed on a phone before the desktop app can be used, so there is no phone-free desktop-only account; Tana the free plan hosts only 5 meetings a month with AI transcripts and summaries
  • They diverge on capability: Signal covers End-to-end encryption, Tana covers Outliner interface.
