Tiny Little Office
The link as the document is one of those ideas that feels obvious the second you read it, and that's usually a good sign. Most office suites are built around files, folders, and the fiction that we all organize our work the same way. In practice, a huge share of what teams actually share is a URL, and the context around it lives in a chat thread that scrolls away forever. Tiny Little Office puts the discussion on the link itself, which means the reasoning behind a decision stays attached to the thing it's about.
I'd want to know how it handles the messy parts, like what happens when a link rots or the underlying page changes. That's where a tool like this either becomes a durable record or just another tab people lose. There's also a question of whether it stays a tiny office on purpose, or quietly grows into the heavyweight thing it's trying to escape.
Still, I like the direction. The best productivity tools lately have been the ones that subtract, and a suite that treats a link as a first-class object is subtracting a lot of overhead. If it keeps the scope small and the discussion tight, it could carve out a real place for itself.
