In West Africa, most businesses never adopted accounting software. The corner shop, the market stall, the wholesaler, the tailor, the online seller on WhatsApp or Facebook Marketplace: they all keep their books in a paper notebook and run their business on WhatsApp. Debts get forgotten, stock runs out, and the day ends without a total.

Kayé is a business assistant that lives entirely inside WhatsApp. Nothing to install, nothing to learn. Merchants talk to it the way they talk at the counter: a voice note, a photo, a short message. Kayé keeps the whole business: sales and credit, mobile money payments, stock, expenses, supplier debts and due dates, team members, daily summaries and polite reminders. It photographs-to-ledger a handwritten sales book, and sends receipts, settlements and statements as images the merchant forwards to the customer, in their business's name.

The model proposes, the merchant validates, the code writes. Muse Spark 1.3 turns each message into typed tool calls and reads handwriting; Muse Voice Transcribe 1.0 handles French voice notes; SAM 3.1 counts stock on a shelf photo; Muse Image 1.0 draws a logo for businesses that have none. The code resolves names, recomputes every amount, and writes nothing before the merchant taps "Yes". One long voice note with several operations becomes one recap and one button.
