Notion, as any other thin-AI product out there, is now in Anthropic/OpenAI/Google's crosshairs. Unless one has a moat the size of SharePoint or Google Docs or OneDrive, it's just a feature away.
It works, but models seem to have these insane long traces to do the most basic things. I had to create a couple of skills so they know how to properly use the thing without breaking, so they don't always try to pass the wrong parameters to it.
It also doesn't let us change a couple of things (like icons). Or, if it does, not even Opus 4.6 can figure out how to do it.
