How this list is made

Every week we ask the same 12 questions, 2 times each, of ChatGPT and Claude (both searching the web live) and Gemini (answering from what it knows; Google's terms don't let tools like ours analyse its web-search answers). The questions are worded the way readers really ask. We read which books each answer recommends, count each book once however it is spelled, leave out any book or author the question itself named, and rank by the share of answers that name it. A list is published only when every assistant answered.

This week: 72 answers (48 live, 24 from memory). Question set uk-1, run 5 October 2026.

  1. “What are the best cosy crime novels ever written? I want something proper comforting with a good puzzle.”
  2. “I've never really read cosy crime before, where should I start? Any easy first books to dip into?”
  3. “What are the best new cosy crime books that have come out in the last year or so? Fancy something fresh.”
  4. “Are there any underrated or lesser-known cosy crime novels worth reading? I've done all the big names already.”
  5. “Need a birthday present for my nan who loves a nice cup of tea and a cosy mystery, what cosy crime book would you get her?”
  6. “Looking for a cosy crime book to read on a rainy weekend with a blanket and a brew, any suggestions?”
  7. “Can you recommend cosy crime set in a village bakery or tea shop? Bonus if there's a bit of humour.”
  8. “I absolutely loved The Thursday Murder Club, what other books are like it?”
  9. “I've read everything by Agatha Christie and loved it, who should I read next?”
  10. “Which cosy crime novel would be a good pick for our book club that will get everyone talking? We're a mixed group of friends in our 40s and 50s.”
  11. “What are the best cosy crime novels by British authors? Proper English village vibes please.”
  12. “Is there a cosy crime series that's worth starting? I like getting stuck into a long series with characters I can get attached to.”

A list shows what the assistants said that week. It is not a ranking of quality or of sales, and nobody pays to be on it.
