Sovereign by design. Verifiable at every step.
You decide where your AI runs — and your confidential data never leaves your company.
We're looking for pilot partners. Apply55-second overview: a private daily assistant, spreadsheet formulas written by cloud AI, and recurring reports that run in-house and wait for your sign-off.
Keep confidential files fully offline on your servers, or switch on cloud AI per task when you choose.
Let leading cloud AI build the workflow once. Run recurring invoice checks and sales analyses repeatably in real code and local models.
Real spreadsheet formulas instead of guessed numbers, full document change history, and human sign-off before anything is sent.
The sales export arrives by email. Zokai Station drafts the narrative and the slide deck, then waits for your approval.
See it at 16:00 →Policy violations and likely duplicates are flagged with real spreadsheet formulas you can check yourself.
See it at 11:00 →Review contract archives and prepare checklists inside your perimeter, with a record of every change.
See it at 18:00 →Everyone is building the proactive assistant. Ours runs where you decide, and at the end of the day you can see and verify everything it did.
Before you open your inbox: the client inquiries that matter, today's scheduling conflicts, overdue milestones. Ask it to block prep time for your afternoon meetings, say "Book them", and it's done.
Your choice of modelWatch the assistant synthesize executive priorities and book time blocks directly into the calendar on a single confirmation.
"Find all unapproved expenses over €500 and show me the formulas." The assistant writes real formulas into the spreadsheet. You check the total yourself: €7,494.40.
Figures from formulas, not from the modelThe assistant audits spreadsheet data: generating formulas, policy disallowance checks, and audit aggregates directly in the sheet.
The report arrives by email. The assistant analyses it, writes the board narrative and builds the slide deck, then stops and waits for your approval. Nothing goes out without you.
Waits for your approvalWorkflow execution: data analysis, structured narrative, your sign-off, and presentation generation.
Open any document and see its history: every change, when it happened, and where it came from. Go back to any earlier version. Workflow runs and approvals are recorded the same way.
Recorded on your infrastructureThe assistant restructures a client proposal; the document history shows every change and where it came from.
Zokai = zōka (増加, Japanese for growth) + AI. Every document, workflow and approval adds context, so your assistant gets more useful the longer you work with it.
Watch the whole day: 6 recordings →Client files and deal data stay inside your perimeter. Review contract archives, prepare compliance checklists and run routine due-diligence checks, with a record of every change.
Turn recurring client deliverables into workflows. Calculations run in code rather than on paid AI tokens, and the AI steps can run on local models.
Built to help you meet GDPR, DORA and NIS2 requirements: you choose the hosting jurisdiction, confidential data can stay fully offline, and every change is recorded.
AI proposes. You decide. Every time.
Your own hardware, your data centre, the provider you trust, or dedicated servers we operate for you in Germany.
Fully local models for confidential work, cloud models when you choose them. Switch at any time. In fully offline mode, nothing leaves your servers.
The assistant only gets the tools you allow. High-stakes steps like sending, booking or approving wait for a person.
Documents, spreadsheets, notebooks and workflows are stored in open, standard formats. They're readable without Zokai Station, so you can leave whenever you want.
# Flag likely duplicate invoices
for a, b in pairs(invoices):
same_amount = a.amount == b.amount
similar_vendor = similarity(a.vendor, b.vendor) > 0.9
if same_amount and similar_vendor:
flag(b, reason=f"matches row {a.row}")Under the hood, Zokai Station writes real code to do the work: formulas, scripts, workflow steps. You never have to read it. You see plain steps, test them on last month's data, and approve. The code stays there for anyone who wants to check it.
"Skip invoices under €100." "Ask me before anything goes to the board." The assistant updates the workflow, checks it, and runs the test again.
There's no feature wall. When the spreadsheet or a workflow lacks something, the assistant writes it as a script you can inspect, and keep.
Test runs replay a real past event. Reading is real; sending and writing are blocked.
Every change, run and approval goes into a record that you can verify yourself.
You don't have to move your whole office. Start with one sensitive, recurring process, the one you'd never paste into a public chatbot. Run it in Zokai Station on your own data for four weeks. Keep everything else as it is.
