Kurahi by KODA SōKEN · self-hosted enterprise agent platform
Agents that work for you. Decisions that stay yours.
Kurahi connects to the systems you approve, prepares the routine work your teams do every day (invoice cases, reply drafts, approval packages, design documents for legacy code) and brings every decision to the right person. You set how far each routine may go on its own. Japanese-first, in English too.
- Runs inside your network
- Autonomy from L0 to L3, set by you
- Signed evidence for every run

In the product
Prepared by agents. Checked by policy. Decided by people.
Real screens from the Kurahi console, shown with sample data. An invoice asks to change the supplier's bank account: the agent prepares the case, a policy check stops it, and only a person can decide.
- 01
Prepared
Work arrives as cases in each department's queue, with the source attached and the status visible to everyone involved.
- 02
Checked
Every case passes the company's policy checks. A bank-change request fails as suspected fraud and blocks approval, with the policy version on record.
- 03
Decided
Only a signed-in person records the decision. Required approvals and separation of duties apply, and every step leaves signed evidence.
Choose how much to hand over
Autonomy is set per routine, never assumed. A routine earns a higher level from its own record, a person accepts it, and a serious error lowers it again.
Inside your boundary
Kurahi is a service you run, not a service you send data to. People sign in with your identity provider, the agents read your systems where they are, and evidence stays on your servers.
Built for your security review
The controls your information security team will ask about are part of the product, not an add-on.

Find by challenge
Start from the problem. Each one links to what Kurahi does about it.
- Internal approval requests stall on paper and in email
- Checking invoices and expense claims takes too long
- Competitive quotes and purchase orders take hours
- Shared inboxes and request mail pile up
- Keeping overtime within the legal limits (the 2024 problem)
- Legacy systems have become a black box
- Security reviews and audits ask how AI is controlled
- Ransomware and malware on shares and attachments

Frequently asked questions
Security
Where does our data live?
In your network. Kurahi is installed and operated on your own servers; work items, documents, evidence and the audit log are stored there. Connectors and model providers are off until an administrator turns them on, so data reaches a cloud service only through the ones you configure.
What leaves an audit trail?
Every autopilot run writes a signed evidence bundle: a hash-chained event log and a signed manifest recording what was read, what the model proposed, each decision and the approval it ran under. Approvals, flag clearances and configuration changes are in the audit log. Evidence can be verified offline.
Product
Which AI models does Kurahi use?
The ones you choose. Agent sessions work with hosted, self-hosted and local models, including models that run inside your network and IBM watsonx.ai. Autopilot reasons through a model backend with no tools. Changing provider is configuration, not code.
How is autonomy limited?
Each routine has an autonomy level set by your administrator, from L0 observe to L3 act externally. L3 only works under a standing approval a person made, limited to named recipients, a template, a daily maximum and an expiry. Payments, contracts, decisions about people, bank-detail changes and anything flagged always go to a person.
Getting started
What is free?
The self-hosted platform: the editions, the work queue with approval routes, the connectors, Word, Excel and PowerPoint documents, SSO, SCIM and roles, attachment scanning and autopilot at L0 and L1. Security is included in every plan. Digital staff at L2 and L3 and the enterprise features are by written agreement.
Do you support Japanese?
