Things I've Built

I was coding well before AI, but the AI coding tools really shifted things — they lowered the bar enough to build custom apps where I'd previously settle for whatever was on the shelf, or to prototype something without weighing it against a whole lost weekend. Here's a collection of some of the things I've made recently.

Can you use them too? Probably not — while not strictly vibe-coded, they're highly customized to my needs and I don't want to spread security or reliability risks.

Grocer

My own shopping list app. Mobile-optimized, tolerant of the grocery store's milk-fridge cellular dead zone, very quick data entry, and recommendations based on our consumption patterns (we buy a lot of milk, eggs, and buns for school sandwiches).

RSS reader

The best-in-category reader, for me, after ~25 years of Google Reader, Inoreader, NewsBlur, Feedly, The Old Reader and others. No ads, no paid team features. An LLM classifier tags every article I read so I get quantified-self stats on my media diet. Runs for about ~$1.5/mo.

Chef

Takes a recipe URL and uses an LLM to translate it to Hebrew, convert to metric, strip the mom's-kitchen stories / ads / SEO filler, and restructure it with inline quantities the way I like. Food tastes better now. It even generates food images with Nano-banana for laughs.

Kipi

My own claw-like LLM harness, built from scratch because OpenClaw is a security dumpster fire and I wanted to understand the tradeoffs. Helps organize and remind, though I still don't trust it with sensitive stuff (messaging, email, calendar) until I figure out sandboxing. The big functionality leap came from giving it Tavily and Playwright to research and act.

City Builder

There aren't any good English-learning apps for kids — they're all the same slow, bloated $12/mo subscription. My kids' English is mostly from Minecraft (great vocabulary for natural resources and mythical creatures, less so everything else), so I built a SimCity-style game to stretch their language into new domains.

Todoisn't

A from-scratch take on the subset of Todoist I actually use. A genuinely hard one: tight iOS integration, notification logic, audit trail, and countless tiny UX details are challenging to get right. There's a lot left to do here before I'd migrate such a core part of my workflow. My already high respect for the Todoist team only grew.

Chords

I've messed with virtual modular synths since Native Instruments' Generator in 1996; the natural evolution is just yelling instructions at Claude Code ("add a knob that staggers notes 0–200ms", "add a kick-and-hats drum track", "add a low-pass filter knob"). A jam-session machine in ~100k tokens.
