Free vs Plus




Free (this page)
  • source breakdown by percentage
  • biggest available lever
  • text export and print
  • all citations and cautions


Plus (optional, one-time)
  • calendar (.ics) shopping reminders
  • unlimited share images
  • share card without the 'Made with CortexLit' footer


Checkout isn't live yet, so Plus is unlocked here with a local code. The check runs in your browser and can be bypassed; it is a placeholder for a real payment link.






Free tier: 1 share image per result.






Commercial disclosure: optional paid Plus tier; all evidence, cautions and the main result are free. No affiliate links, no sponsors.
