Already using myBillBook?

KAI's built-in migration wizard imports your historical data directly from myBillBook — no re-entering months of invoices and records by hand.

Truly offline, not just an "offline mode"

KAI has no server dependency at all — it isn't a cached fallback for when the internet drops, it's the actual architecture.

Your data never leaves your device

No cloud database holds your invoices or customer records, unless you choose to back up to your own Google Drive.

Own the source code

Enterprise and white-label clients can own KAI's full source code — not something typically available from billing apps in this category.

AI that respects your privacy

Bring your own AI key — KAI never routes your business data through a Muladhara server to power AI features.
