Seven things
I build.

Software for people who want to keep their own record. Four are shipping, three are still in the workshop.

Fig. 1 The scales of one record, from a second to a life, ruled as a slide rule is. Each product sits on the scales it works at. Tractor and Silo’s month is the one scale it does not write yet.

Tractor and Silo

Web and iPhone, live

Every app that tracked your day, gathered into one journal you own, and can add to.

  • Your phone records where you went. Your Mac, your code and your wearables fill in the rest.
  • A daily summary per source, a timeline, the people you were with, the places you stopped.
  • You add the part no sensor catches: what it meant.
  • Export everything, any time. Nothing is sold and nothing is mined.

My own record, sixteen years of it.

Fig. 3 Sixteen years of my life in Tractor and Silo, from 28 May 2010 to 20 September 2026: 34,452 experiences on 5,055 days. The app draws a year as a row, a column a week and a dot for every few experiences. Each row is scaled to its own fullest week, and the number at its end is how many experiences one dot holds.

Lens

macOS, public beta

Your Mac remembers what you worked on, then writes the day up for you, without sending anything anywhere.

  • Sits quietly in the menu bar capturing screens, apps and audio while you work.
  • Writes your daily summary with a model built into the app. On a Mac with 16 GB or more, there is nothing to install, no cloud call and no API key.
  • The archive stays on the machine unless you say otherwise.
  • On the roadmap: sending your desk time to Tractor and Silo, into the same journal as the rest of your life.

Answers to Answers

Web and iPhone, live

One question a week to your whole family. Everyone answers privately, and the answers are revealed together.

  • Nobody sees anybody’s answer while the question is open. When it closes, every voice arrives at once.
  • Answer with text, a photo, or your own recorded voice.
  • A relative who has joined the circle but will not install an app answers by replying to the question email. Their words land in the digest with everyone else’s.
  • Answered questions go into your circle’s archive, grouped by year, where only your circle can read them.

Marquee

macOS, shipping v1.0.0

Turns folders of photos into one video you will actually sit and watch.

  • Folders in, an MP4 out. No command line, nothing else to install, no account.
  • Almost every photo pans and zooms, with its date and the place it was taken burned in automatically.
  • A picture frame chokes on six thousand loose images. One looping video plays them all day.
  • Runs entirely on your Mac. It makes no network calls, even to name the places.

In the workshop

Built and running, not yet handed out.

Real software I use every week. Nothing here has a download yet, and nothing here pretends to.

Tractor and Silo Ledger

macOS

A Mac app that stays open beside your work, for the part of the record no sensor can write: what it meant. Capture has its apps and synthesis has the web journal. Ledger exists so the record gets written about.

In TestFlight

Transcriber

macOS

Transcribes audio and video on the Mac itself, a whole folder at a time. Right now it is working through my family’s home movies: forty-one years of footage, 1983 to 2026, about five terabytes.

In daily use

Photo Describer

CLI and macOS, open source soon

Reads a photo archive and lets you search it by what you remember, “opening gifts in the living room”, instead of by filename or date.

Going open source
Why they fit together

Capture, enrich, synthesize.

Everything above exists to produce one thing: a record worth handing down. Capture happens on hardware you already own. Enrichment is the context only you can add. Synthesis is the gift you are buying for future-you.

Data ownership is a right, not a feature.

Your life data should live on your terms: exportable, portable, yours forever. We don’t sell data, we don’t mine it, we don’t lock it in.

Capture happens on your hardware.

Tractor and Silo for iPhone captures your timeline on-device. Lens for Mac captures and summarizes locally on Apple Silicon. Lens is Mac-local by default. Tractor and Silo for iPhone is hybrid by design: capture is local, your enriched journal lives in the silo your account owns, and you can export your data at any time.

The Legacy Test.

“Will my children find this meaningful in 30 years?” This guides every feature decision.

Built by one person, for real people.

No venture capital, no growth-at-all-costs pressure. Just thoughtful software that earns its place in your daily life.
