Bit.ai

Bit.ai is a team knowledge platform – documents, wikis and workspaces – with AI writing and document building inside the editor rather than bolted alongside it. Version 3.0 is the current release.

The distinction it draws is between documents and knowledge. A folder of files is storage; a wiki with connected search is something a new joiner can actually navigate. Bit.ai organises around workspaces, wikis and cross-linked docs, which is the structure that determines whether written knowledge gets found six months later or quietly rots.

It sits in a category with very well-funded competitors, so evaluate it on the specifics of how your team actually works rather than the feature list, which looks similar across all of them. The usual knowledge-base caveat applies and no tool fixes it: the platform makes documentation easy to write and cannot make anyone keep it current.
