What Paperfoot works on

  • 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 Aging Research 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.

  • Infrastructure for AI agents

    Software that lets people and AI agents work on the same documents, contracts, invoices, and payments, with a person approving what matters. This is Uniport and Imprest, along with open-source command-line tools for AI agents.

Projects

  • 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.

  • Aging Research 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.

  • Uniport

    One private app for documents, spreadsheets, contracts, invoices, shops, and payments. New documents and spreadsheets are end-to-end encrypted on your device by default, and the key travels in the part of the link after the #, which never reaches Uniport’s servers. Contracts and other PDFs go out for electronic signature, and each signed PDF ends with a signing record. Invoices, shops, and payment links take USDC, USDT, or bank transfer straight to your own wallet or bank; Uniport never holds the money and takes no cut. It is free to start, with no account, and an AI agent can open and edit a file from its link.

  • Imprest

    Financial accounts, payments, and permissions for AI agents. Agents connect through MCP or an API, and each is scoped to an account with read access or a payment-request allowance that expires when you choose. Agents can ask to pay but cannot spend: you check the recipient, amount, and purpose of each request and approve it on your iPhone with Face ID or your passcode, and agents never receive your signing keys. Balances, activity, and statements are in a web portal, accounts hold USD Coin (USDC) on the Base network, and people can pay each other by @handle or pay link. The iPhone app is in beta.

Questions

  • Is Paperfoot an AI company?

    Yes. Paperfoot builds software on AI models and calls its goal superintelligence, or SI: systems that can work through more of the evidence on ageing and health than any one person can, and help people act on it. Its products support researchers, pet owners, and vets; they do not replace them.

  • Where is Paperfoot based?

    Paperfoot AI Pte. Ltd. is registered in Singapore. Its founder works between London and Singapore, and its products are available online.

  • Does Paperfoot publish open-source software?

    Yes. Paperfoot’s GitHub organisation publishes open-source command-line tools for AI agents, mostly written in Rust, such as search-cli, which combines several web search providers, and aiseo, which audits pages for search and AI citation. In October 2026 it had 35 public repositories.
