You can upload all your documents and work/share them individually. Then linking between becomes easier because they are not just Word files sitting on disc.

For SaaS:

- freemium plan for 1 user - paid plans based upon number of users

On-premise:

- download and install core product - enterprise features like AD auth, redacting, workflows are paid for

We plan to put the core product source code onto Github so anyone can have their on hosted "wiki".

Hope this makes sense.
