    Tettra is an internal knowledge base with smart workflows to help you answer repetitive questions. Tettra helps you document important processes, policies, and procedures in one centralized place. This makes onboarding new teammates much faster and answering questions less repetitive. Most of our time is spent in cloud apps. As software continues to eat the world, the amount of information we create and the number of tools we use continues to rise. With all this information comes downsides. This fragmentation of tools and teams makes it tough to share context and agree on the best decisions, especially cross-functionally. On growing teams, your best employees shouldn't be bogged down by repetitive questions. To move fast, everyone needs access to the same information and principles. Your internal knowledge base will only be successful if everyone contributes to it. Tettra makes it easy for anyone to contribute knowledge by referencing content in other systems.

We can host and build multiple versions of your docs so having a 1.0 version of your docs and a 2.0 version of your docs is as easy as having a separate branch or tag in your version control system.
