What Paperfoot builds

• Longevity research

  Superintelligence that helps researchers read, weigh, and compare the science of ageing across species, with a focus on dogs and humans. This includes models that bring genomic, proteomic, and clinical data together, and AgingResearch.News, which follows new papers as they are published.

• Companion animal health

  Health records, lab result tracking, and everyday guidance for dogs, cats, and other pets, kept in one place and shared with the vet who treats them. This is Petus AI, which also runs a canine research programme on the biology of ageing.

Products

• Paperfoot

  Superintelligence for computer science research. It reads every new computer science paper on arXiv, judges each on its own work, never on fame, and writes up the ones worth reading in plain words the day they are posted.

• Petus AI

  A pet health platform for dogs, cats, and other companion animals. Owners keep one health record built from lab reports, clinical notes, and everyday observations, follow comparable results over time, set reminders for vaccinations, worming, and medication, and ask questions answered from their pet’s saved history and published veterinary guidance. A free account includes the record and sharing it with your own vet; Plus adds up to five family members. Clinics can run appointments, patient records, notes, and billing in one workspace. Petus helps owners prepare for the vet; it does not replace one.

• AgingResearch.News

  A news service that reads new papers and preprints on ageing and longevity, judges each one on its evidence, never on fame, and turns a selection into short, plain-language stories that name the kind of study and cite their source. Readers can search the record, ask questions, follow topics, and get a feed fitted to their own research. On 11 October 2026 its public status page counted 355,340 papers read from 9,409 journals and preprint servers, 24,117 of them about ageing, and 967 stories published.
