Some features I think are pretty cool:

- We can render pixel perfect PNGs and PDFs (native vectorized PDFs)

- You can pass an xlsx, inputs, and output cells, and get a JSON API from any excel workbook

- You can pipe a postgres query into an xlsx file, and then run excel formulas over it

- You can pretty easily setup a `git diff` helper for xlsx files that shows you the changes you care about

- We have a built-in terminal, auto-launchers for Claude and Codex (with some fancy hooks that inject context when you send messages) and a pretty good MCP. After you install Nobie you're agents can do pretty much anything in an xlsx. We also provide a lot of tools that give agents high-signal information about the workbook, so they can quickly get up to speed and do good work

- You can programmatically edit workbooks in pleasant ways, and the workbook will update properly, AND recalc incrementally, AND the numbers will tie with Excel (if they don't definitely let us know, but we've put a huge amount of work into making sure they do)

- There's a bunch of examples on the CLI page on the website, but a lot of previously impossible/very hard things are now pretty trivial with our CLI, and I think this'll be really useful for for a lot of devs (the CLI will be getting better throughout this week, I have a lot more stuff I want to do with this)

- Happy to talk technical details. Everything is from scratch, and our render and calc engines have been a massive amount of work.
