The tool that tells me no

I built a swing trading scanner for the ASX. It watches the market, runs backtested patterns against the ASX 300 and a curated watchlist, and sends me one email at 7pm each weekday. If something meets the criteria, I get a signal with entry, stop loss, and target. If nothing meets the criteria, I get a short email that says so.

Most days, it says no.

One button, five destinations

I’ve been thinking about this one for years. I’d written about voice transcription on my German blog more than once, always circling the same frustration: I think faster than I type, I often think in German but need to write in English, and by the time I’ve opened an app and found the right place to put a thought, the thought has changed shape or disappeared entirely.

The tool I wanted was simple to describe and surprisingly difficult to build well. Press one button on my iPhone. Talk. Done. The system figures out the rest.

The invoice that writes itself

This one doesn’t use AI at all. It doesn’t need to.

I tag my calendar entries with client codes like @KK or @AA-consulting. At the end of the month, the tool reads my calendar, calculates the hours, generates a PDF invoice with the correct rates and exchange conversions, and files it. If a client pays in euros, it pulls the RBA exchange rate so the ATO gets what it needs when tax time comes.

The receipts can wait

Every quarter I used to lose an entire afternoon to the same ritual. Dig through emails, download PDFs, open bank statements, match invoices to transactions, sort business from personal, convert USD and EUR to AUD, file everything into folders my tax person understands. It’s the kind of work that makes you question your life choices.

I run a small operation. Invoices arrive by email in three currencies. Receipts come as PDFs, photos of paper, forwarded attachments. Some are from Anthropic in US dollars, some from German clients in euros, some from the local office supply shop in AUD. Each one needs to be read, categorised, and filed in a way that survives an ATO audit.
