The killer feature here is an auto assembling todo list, punchlist, project management.

Discussing what needs to be done next, and having it automatically sort it into what subtask it is, if it applies or is blocking to multiple other tasks. Recording specifications, measurements, dimensions. Being able to ask other people facts and have them correctly documented into the right task.

Company Brain / Knowledgebase is imho more rear facing, whereas todo is future facing.
