One context layer. Any model. Your servers.
Every employee gets a personal AI assistant that knows their company.
Documents in SharePoint, notes in heads, processes in wikis. No employee has the full picture.

European companies depend on US cloud providers. GDPR compliance is questionable.
Each employee's individual context: writing style, preferences, meeting notes, personal workflows. AI that adapts to you.
The organization's collective knowledge: processes, documentation, internal language, institutional memory. The foundation everything builds on.
The intelligence layer is replaceable. The context stays. Switch models anytime without losing what makes your AI valuable.
Claude today, Mistral tomorrow, open-source next week. The intelligence is replaceable, the context stays.
Your data on your servers. No US cloud. GDPR-native. AI Act ready.
Each team member gets a personal brain connected to company knowledge. Productive from day one.
