ONE WORKSPACE · PROJECTS · AGENTS · SKILLS · CITED DOCUMENTS

Real work, done inside your walls.

A workspace where your teams delegate to specialist AI agents and get back finished, fully cited documents — Projects, Agents, Skills and Drafts in one window, running on infrastructure you control.

Grounded in your sources

Every claim traces back to the exact file and page it came from — no hallucinations, just your documents, read closely.

CITATIONS

Finished documents

Memos, reports and decks assemble into formatted Word, PowerPoint, PDF and Excel — generated inside your environment.

Never leaves your perimeter

On-premise, sovereign EU cloud or air-gapped. No data egress in normal use, and never used to train a model.

ON-PREM · ZERO EGRESS

Your teams are using AI. The question is whether you can see it.

01
Shadow AI is already here.
Confidential documents are pasted into consumer tools every day. Banning AI doesn’t stop it — it just removes your visibility.
02
Public-cloud AI moves your data off-site.
It’s processed on infrastructure you can’t audit, under terms that can change — and much of it touches US-jurisdiction infrastructure.
03
Your data can become someone else’s model.
On many tiers, what you send trains the next version. For privileged or regulated work, that exposure is unacceptable.
04
Unauditable AI is DORA / NIS2 / AI Act exposure.
“We used a public chatbot” is not a defensible answer when the regulator asks where data went and how you’d exit.
Diana’s answer: keep the workspace inside your perimeter, hold the keys, and record everything — so AI adoption is defensible, not dangerous.

Every answer, traced to its origin.

Drop in a project's worth of contracts, filings and notes. Diana reads across all of them at once and links every sentence back to where it came from.
