Aider built a $27.81 bridge between Amazon and YNAB
Matching Amazon orders to YNAB entries by hand was tedious, so the writer vibe-coded a Chrome extension with Aider that reads Amazon orders, matches them to YNAB, and uses Claude's Haiku to clean up the memo line.

What they did
The writer vibe-coded a Chrome extension with Aider that reads order and purchase data from Amazon’s website and matches it against their YNAB budget entries. It updates the YNAB memo line with the item names, running each name through Claude’s Haiku model first to clean up Amazon’s product naming into something reasonable.
How it went
This has been working well for the writer overall; it requires them to visit Amazon on desktop and click the extension to sync, but that’s easy enough and makes their budgeting way easier. It cost $27.81 in API credits to build, before Claude Code or coding subscriptions existed.
Try it yourself with Aider
Build a browser extension that reads my recent orders from [a shopping site], matches each one to the corresponding entry in [my budgeting app], and writes a cleaned-up item description into the memo field using a small model to tidy up the raw product name.
A starting prompt written by Agents in the Wild. Fill in the [brackets], and check what the agent does before it sends, pays for or deletes anything.
A former PwC tax preparer did their own return with Claude, then again in TurboTax. Claude read the forms and statements and caught a missed credit, and the two matched to the dollar after reconciling.
Working abroad, they didn't know the local systems. Gemini flagged a pension account they could cash out when leaving the country, and Claude caught risky clauses in a contract too small for a lawyer.
Why pay to file? They had Claude fill the same forms on TurboTax and TaxAct, compared the numbers on FreeTaxUSA, then filed on the free one and kept the $150 filing fee.
In a meeting about a bug in an app they didn't own, they told Claude to find out if it was user error, notify the user, and tell the developer what to fix. Fifteen minutes later, the developer asked: today or Tuesday?
After $45 in GitHub Actions overage in one month, a solo founder put an idle homelab to work as CI runners, with Claude making it easy to set up. Daily spend dropped from $2-4 a day to under $0.25.
A first homemade synth has 36 hall-effect keys and buttons and 7 rotary encoders. The firmware started by hand, then gentle prodding at Claude got everything needed much faster. Rev 2 of the PCB is nearly done.
