Things that read for you
The inbox, the supplier PDFs, the forms, the scans of handwritten job sheets. An AI reads them, pulls out what matters, and either files it where it belongs or puts a one-line summary in front of you. Email gets sorted into "needs you", "needs someone else" and "needs nothing". Supplier delivery dates get lifted out of attachments and into your job system. Invoices get matched to the orders they belong to.
This is usually the first thing that pays off in a business, because it's the first thing that's eating the morning.
