What you are reading

  • Excerpts — at most 400 characters — of AI engine responses to standardised buyer prompts. Never full answers.
  • Index measurements only. Customer scans are never archived here, at any granularity.
  • Highlighted names are the products the extractor recorded in that answer. A mention is not an endorsement, and this page ranks nothing — the ranking does that, with sample sizes.
  • Engines whose terms do not permit republishing generated text appear with their excerpt withheld, never hidden.
