For company departments

## Answers from documents — for support, sales, legal, HR, finance, marketing and management

Each use case covers one department’s questions to its documents, real screens of the knowledge space and what the AI agent does not do. No code is needed; your IT specialist connects the documents once.

The first step changes nothing in your documents or your code

## Start with a question about your documents or your project

Create a knowledge space and ask about a policy, a contract or a report — or connect a repository and ask how your code is built: the AI agent reads and answers in minutes, changing nothing. A starting balance is provided to try it out.
