Chairwise
Built at Meta Global AI Developer Hackathon · Oct 26, 2026 · Remote
I'm a barber and a Penn State engineering student. Most barbers I know work for themselves. We rent a chair, buy our own supplies, and pay our own taxes, including 15.3% self-employment tax on top of income tax. The problem is simple. We hold clippers all day, not receipts. A $40 set of guards here, a supply run there, and the receipt ends up in a pocket or the washing machine. At tax time, the accountant asks what we spent, and we guess. Every $100 we forget costs at least $14 in tax. Chairwise fixes that by letting barbers log expenses the way they'd send a text. Between clients, you tap the mic and say something like "Bought clippers for $89 at Sally Beauty with my card, and drove 12 miles." Chairwise turns that one sentence into two tax records: the clippers and the business miles, each on the right Schedule C line. If you drove to buy something, you just tick "Drove there for this?" and the miles are saved with it, at the 2026 IRS rate of 72.5 cents a mile. Got a receipt? Snap a photo and Chairwise keeps the business items and leaves the snacks out. Lost it? Upload your bank statement and it sorts every charge into business, maybe, and personal. It even leaves gas out on purpose, because the mileage rate already covers it. At tax time, one tap gives your accountant a Schedule C summary, a spreadsheet, and every receipt photo. No shoebox, no guessing. I care a lot about privacy. Your records stay on your phone. There's no bank login and no account, and statements are read and then thrown away. If there's no signal, it still works. Chairwise doesn't file your taxes. It just makes honest record-keeping fast. Estimates, not tax advice.

Everything here was built during the event, starting Oct 27, 2026, and the commit history shows each step. It's built on the Meta Model API, Netlify, and Google Fonts, with no third-party code libraries. Marcus in the video is a fictional character.
