Where each one falls short

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

Google Lens

  • Product identification results are commercially influenced, since Lens surfaces shopping listings that connect to Google's ads and shopping business rather than purely neutral matches.
  • Accuracy on plant, animal and object identification varies significantly and is not reliable enough for anything safety-critical such as identifying a poisonous plant or mushroom.
  • It requires camera or photo library access, and photographed content passes through Google's recognition systems, which is a consideration for sensitive documents.
  • It is bundled into other Google products rather than a discrete standalone app on iOS, so discoverability and access differ by platform.
  • Translation quality is inconsistent for handwriting, stylised fonts and less common languages compared with clearly printed text in major languages.

Karabiner-Elements

  • It requires granting significant system-level permissions, including input monitoring, which some security-conscious users are reluctant to allow.
  • Writing custom complex modification rules by hand means editing JSON, which is a real barrier for a non-technical user without the community rule library.
  • It only remaps keyboard input, so a user who also wants gesture or window management customisation needs a second tool such as BetterTouchTool or Rectangle.
  • Being an unpaid open source project, support depends on GitHub issues and community forums rather than a vendor support desk with guaranteed response times.
  • It is Mac only, so it does nothing for remapping needs on a Windows or Linux machine in the same household.
