The work

A macOS text editor built for absurdly large files: logs, exports, database dumps. When everything else beachballs, Caxton opens it. Read a ten-gigabyte log end to end, or pivot the same file into a grid and sort it like a spreadsheet.

Text view and grid view

A safety layer in front of your CRM. Preflight checks HubSpot and Salesforce imports before they land, catching duplicates, malformed fields and mismatched properties, and it runs migrations between the two, so records arrive mapped and clean instead of needing to be unpicked afterwards. Built for agencies running many portals at once. Still in development.

Trip Captain reads the coverage documents you already have: your credit card benefits guide, travel insurance policy, cruise or rental protection plan. It shows you, side by side, what each one covers and exactly where the gaps are. Still in development.

A dictionary that answers at your child’s level. Type or say a word, pick an age, and WhyBuddy explains it in language a child that age will actually follow. Everyday questions like what inflation means, homework words like photosynthesis, and the harder conversations about death, divorce or illness, handled with care. Keep a profile for each child, set religious and cultural preferences, scan a word straight off the page with the camera, and save the explanations worth keeping.

WhyBuddy's home screen on iPhone

A toolbox for designers and developers that runs fully offline and asks for nothing. Convert across eleven units, from pixels and points to em, rem and viewport widths, with history, presets and batch conversion. Then keep going: screen and aspect ratio calculators, a typography scale generator, and CSS or SwiftUI you can copy straight out. No account, no ads, and the Pro tools are a one-time unlock rather than a subscription.

Rewriting that reads like a person wrote it. The built-in keyboard works inside any app, so you can fix a line in Mail or Messages without copying anything out. Pick a tone, watch three takes stream in with every changed word highlighted, and check the before and after meter for how machine-generated your text still sounds. Feed it samples of your own writing and the rewrites start coming back in your voice.

A crossword that fights back. Solve every word before the clock runs out. Stall too long and the board shuffles itself, though anything you have already solved stays put. Leave a cursed word sitting and the grid tips into Chaos Mode. A dozen themed puzzles, two clue difficulties, a clock you set between two and a half and five minutes, and power-ups to reveal a letter, freeze the shuffle or buy another thirty seconds. No account, no filler.

Stop drawing black boxes by hand. Auto Redact finds the sensitive stuff for you: card numbers, phone numbers, emails, addresses and ID numbers detected and covered in one tap, faces too with Pro. Unlike a Markup scribble, the redaction is rendered into the image itself, so there is nothing underneath to recover, and every export is scrubbed of GPS and device metadata. Works straight from the share sheet, entirely on your iPhone. No servers, no account, and Pro is a one-time purchase.

The tools

Four hundred and fifty-six small tools, free.

Alongside the apps there is a library of calculators and converters, the sort of thing you need once, quickly, and shouldn’t have to sign up for. No account, no paywall, nothing to install.

The name

The name carries a double meaning: “Highway” represents the journey of building software, while “Enigma” nods to Alan Turing and the code-breaking machine that helped shape modern computing.

Occasional notes

One letter, four times a year.

Release notes, workshop notes, and the occasional essay on making software slowly. Nothing else.

Noted. The first letter arrives with whatever ships next.
