Where each one falls short

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

OmniFocus 3

  • Apple platforms only apart from the web client: macOS 14, iOS or iPadOS 17, watchOS 10 or visionOS 2 and newer are required, with no Windows or Android app
  • Web access is not included with a perpetual licence and costs an extra $4.99 per month or $49.99 per year
  • The Pro perpetual licence costs $149.99 against $74.99 for Standard
  • Future major upgrades are a paid discount rather than free for perpetual licence holders
  • The $99.99 per year subscription is the only option that bundles Pro plus web access

Perplexity

  • Context window has been stealthily reduced despite prior claims of 1-million-token capacity
  • Citations sometimes point to irrelevant or overly general articles that do not support the stated claims
  • Weak performance on complex multi-step reasoning and deep logic compared to dedicated reasoning LLMs
  • Web crawler ignores robots.txt directives and scrapes content from sites that explicitly opted out
  • Pro subscription quotas and feature access quietly reduced without user notification
