This tool gives general information based on the research summarised in Interruptions: The Real Cost and the Cheapest Defences. It is not a medical device, does not diagnose, and does not replace advice from your clinician.

Free vs Plus




Free (this page)
  • formatted re-entry note
  • printable card
  • text export and print
  • all citations and cautions


Plus (optional, one-time)
  • calendar (.ics) return 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.







What this is based on


Every output names at least one verified PubMed source. Identifiers were verified on 2026-10-11 in an earlier batch and carried over into this build; they were not re-queried here, and no retraction database was checked. Verification was at abstract level.

Limits: This formats a note; it does not measure attention or prove a benefit. The attention residue effect is modest and comes from laboratory studies.
