I build software for construction commissioning and QA/QC teams. I work at LotusWorks, and most of the projects here started as a spreadsheet or PDF problem at work: equipment lists, inspection logs, drawing sets and timesheets that someone was reconciling by hand every week.
I also run Visualize Build LLC, where I make Nightglass, a PDF and document editor for Mac, Windows and Linux that runs on your own computer. I built it for the files I deal with every day. It stays fast on huge construction drawing sets, edits the actual text in a PDF, does measurements and quantity takeoffs, compares revisions and redacts for good. There's an optional private AI assistant, no account to sign up for, and your documents stay on your machine.
