FantasyLab · one person, one bench

Small tools that show their work.

FantasyLab is a one-person studio. Six tools so far: a game maker, a statistics engine, and four plain tools for parking, owner pay, job pricing and listing copy. Most of them run on your own machine, and every page says what its tool can't do yet.

Six tools. Each one built for one moment.

They don't share a look, because a parking app and a pricing sheet shouldn't feel the same. They share a rule: show the work, and write down the limits.

  • Foxfire Chase, a game Fantasy Studio built from one sentence: a fox racing through a snowy night forest collecting glowing orbs.
    Windows · free for personal use

    For people with game or video ideas and no engine skills. Type one sentence and get a playable 3D game or a rendered film, made on your own PC.

    Fantasy StudioGitHub
  • Aurora's cartoon polar bear in its blue star hat, holding up a finding card.
    Windows, macOS, Linux · free, Apache-2.0

    For analysts, engineers and AI builders. Drop in a dataset and get findings from real statistical methods, each one cited. When a method can't run, it says why.

    AuroraGitHub
  • iPhone · free, no ads, no account

    For nights out and trips downtown. It finds free parking near where you're going and shows, in dollars, whether the walk beats a garage or a rideshare.

    SpotlessApp Store
  • iPhone + web · free tier, Pro $14.99/mo

    For owners without a finance department. It works out what you can safely pay yourself against 13 weeks of cash, and every number opens to its receipt.

    CounselApp Store
  • The Price This Job tab: three tasks and a trip charge, totaling $352.50 with the minimum met.
    Google Sheets / Excel · $39 once

    For solo handymen and small remodelers. It prices any job from your own costs, so the number you text is one you worked out.

    True Rate
  • The ListingLint checker marking a listing draft: risky phrases underlined by severity, with the facts that don't match struck through.
    In your browser · free checker, Pro $29 once

    For agents with an AI-written listing. Paste it and see every Fair Housing red flag and unconfirmed claim, with the reason and the source. Not legal advice.

    ListingLint

If it can't show its work, it shouldn't make the claim.

Most AI tools hand you a confident answer and hide how they got it. Everything on this bench works the other way round.

There's no venture money behind it, no ads in it, and nobody's data for sale. It's one workstation, built in public.

  1. 1

    Local where it can be.

    Aurora runs offline after its first launch. Counsel and Spotless do their math on the phone. ListingLint never uploads the listing.

  2. 2

    Open where it should be.

    Aurora is Apache-2.0. Fantasy Studio is source-available under BSL 1.1. You can read the code and run it yourself.

  3. 3

    Compute first, then talk.

    Real methods make the numbers. Where a language model is in the loop at all, it only rewords what was already computed.

  4. 4

    Write the limits down.

    Windows only. iPhone only. An estimate, not a quote. Not legal advice. Every page says what its tool can't do yet.

Built in public.
