I gave an AI a physics problem 30 times and ran every answer. Four wrote out a complete, correct-looking setup and never ran the calculation. No error. No output. Reading code tells you if it's convincing. Running it tells you if it's right. alanhalley.com/writing/convi…

Walk Score exists. Bike Score exists. Nothing scores whether a trike can get around — trikes fail where bikes don't: no curb climbing, grade kills you, wind is a routing constraint not weather. Mapped my own routes in Ilhéus into OSM to test it. POC: trikescore.com

Two months ago I posted that Brief Work (briefwork.io) had one paid transaction. Still true, plus a few more since — real briefs, real money, no theater. I'm still the one building it, not running it. briefwork.io

I'm 75 today! I'm still building software, as I have since 1969. AI is much better than punch cards, I have to say.

New prototype: an AI-first decision tool. Describe a decision in plain English — it builds the expected-value analysis, picks the best option, and recalculates live if you edit a number. Live: decisions.alanhalley.com 45-sec demo below ⬇️

Built a marketplace for structured project briefs. Working, one paid transaction. I want to keep building the product. Looking for someone to run it. briefwork.io — DM or [email protected]

A friend asked: "Who is buying all these new apartments in Ilhéus? Locals can't afford them." My guess: Paulistanos. São Paulo has no beaches. Ilhéus is a two-hour flight. I built a prototype to help them find one. beachburbs.com

I added email notifications to an MVP this week. Should've taken an afternoon. Took three days across six AI systems that didn't know each other existed. I was the only integration point. New essay: alanhalley.com/writing/the-g…

Fifteen days after launching my marketplace, I used it to buy a go-to-market plan for my marketplace. Real money. Real proposal. Loop closed. alanhalley.com/writing/real-…

Built a marketplace for short-burst expert work. One brief. One screening question. No cover letter theater. Clients pay $50 to post — quality filter, not a paywall. Experts apply free. briefwork.io

Most of the people I used to argue with are dead or unreachable. This is not a complaint. It is a logistical problem with a partial solution. alanhalley.com/writing/nao-s…

Built a working AI decision tool in one weekend. Describe any choice in plain language → AI builds a decision tree → expected value analysis → optimal answer highlighted. Claude + Stripe. Free + $9/mo Pro. Try it: decisions.alanhalley.com I do this for clients. $500–$5K

I downloaded Obsidian and stared at an empty structure for maybe 5 seconds. That was the beginning of figuring out how to actually work with AI tools. New essay: alanhalley.com/writing/easin…

Built a personal wiki this morning using Claude Code + Obsidian. One terminal session. It read my files, found a forgotten tax bill, a security hole, and two people missing from my contacts. Andrej Karpathy posted the pattern yesterday. I tried it today. It works. @karpathy

Your morning routine: open Gmail. Switch to Calendar. Remember a task. Open another tab. Glance puts all three on one page. Two minutes and you're done. glance.alanhalley.com

Built a Google dashboard concept: Gmail + Calendar + YouTube + Tasks + Drive + News — one page, one login. Why six tabs when you don't need them? Waitlist: google.alanhalley.com

How many tabs do you open every morning just to catch up? Built Glance to fix that. Email + calendar + social + YouTube + Substack + news. One page. Your layout. AI filters the noise. → glance.alanhalley.com

Built a communication triage dashboard concept this morning. AI scores every notification: Urgent / Respond / FYI / Noise. Discord + Gmail + GitHub + Linear. Put it on a wall monitor. Glance up. Stop checking. → signal.alanhalley.com
