Five things I build.
Privacy-first software for people who want to keep their own record. Three are shipping, two are still in the workshop.
iPhone
Tractor & Silo
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 calendar, your code, 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.
After a render
Marquee
Turns folders of photos into one video you will actually sit and watch.
- Folders in, an MP4 out. No command line, no install steps, no account.
- 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.
Day in review
Lens
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. Nothing to install, no cloud call, no API key.
- The archive stays on the machine unless you say otherwise.
- Send it to Tractor & Silo when you want your desk time in the same journal as the rest of your life.
Also in the workshop
Built and running, not yet handed out.
Real software I use every week. Neither has a download yet, and neither pretends to.
Photo Describer
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.

One question a week to your family. Their answers pile up into something worth keeping.

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.
Tractor & Silo is the platform Quantified Selfers have always wanted. For 15+ years, a generation of us has been deliberately capturing — biometric bands, GPS trackers, check-ins, screen recordings, health data, journals, photographs — believing the data was worth keeping. No platform ever existed that could pull it all together. This is that platform, in active development.
Everything in the ecosystem exists to produce a journal entry worth keeping and handing down. We organize life data around the 5Ws — Who, What, When, Where, and Why — because that’s how humans naturally remember.
The spine is a three-verb arc: Capture · Enrich · Synthesize. Capture happens on the hardware in your pocket and on your desk — and the capture surface is still expanding. Enrichment is the context only you can add. Synthesis is the gift you’re buying for future-you — the inevitability that capture earns. We’re building toward it, and some of the work can already run on the Apple Silicon you already own .
The Legacy Test: “Will my children find this meaningful in 30 years?” — this guides every feature decision.
How the Harvest Works
Your life is the farm. Each app and service works a different field — your iPhone captures where you go, your Mac records what you’re working on, RescueTime measures your productivity, GitHub logs your code, Limitless and Omi transcribe your conversations.
The tractor goes out to every field and brings the harvest home. Each source adds its own detail — where you went, what you built, who you talked to. The silo is where it’s stored, preserved, and enriched — per-provider daily summaries, the people you were with, and the context only you can add. The cross-source synthesis layer — the one that lets you ask the substrate what it knows — is what we’re building toward next.
That’s the idea behind the name. The tractor harvests your data from every source. The silo stores and preserves it. Your journal is what you’re left with — something worth keeping and handing down.
Tractor & Silo
Where the harvest is stored
Capture happens on the hardware you already own. Tractor & Silo for iPhone harvests your timeline on-device; Lens for Mac captures and summarizes locally on Apple Silicon. Connect them to your Tractor & Silo journal when you’re ready for the silo to enrich the full picture — and to be ready for the cross-source synthesis we’re building toward.
Philosophy
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 & 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 & 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 silo is where the harvest becomes a story. Per-provider daily summaries, participant tracking, contextual enrichment — and the cross-source synthesis layer we’re building toward, the gift you’re buying for future-you. Capture is what we do today. Enrich is the habit we invite you into. Synthesis is the inevitability that capture earns.
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.
