Sabi: business intelligence for small shops, in the chat they already use Millions of small traders in Nigeria, like booksellers, provision shops and online sellers, run their business from memory and a notebook. They don’t know their real profit, who owes them, which stock is dead, or what to reorder. Accounting apps fail them because they need forms, data entry and good literacy. Sabi works the way they already do. The owner just talks to it on WhatsApp or in the Sabi app, by typing, sending a voice note or a photo, in English, Pidgin, Yoruba, Igbo, Hausa or French. For example: “I sell The Mountain Is You give Tolu, she go pay Friday”. Sabi turns that into proper double-entry books, but nothing is recorded until she taps Confirm. Code checks every entry, so the AI never invents a price, a debt or a profit. From those books, Sabi becomes her business partner: Snapshot: today’s sales, profit, cash, bank, and who owes her. Insights: what is selling, what makes money, what is stuck, and what to order next. Photos: a book cover is matched to her stock, a receipt or notebook page is read into entries, and a price list photo sets up her shop. Marketing: Sabi picks the product worth promoting from her numbers and makes a flyer from her own photo. She can edit it by chat (“plain white background, bigger”), and nothing is posted until she taps Post. Customers: customers chat with her shop on WhatsApp or a web link, and Sabi answers price and stock questions from her real shelf. When she’s needed, for a discount or to confirm a payment, she’s pulled in with one tap, and her reply goes back to the customer. Records for a loan: she gets a business statement and a Sabi score. Built with Meta models: Muse Spark runs the agent and its tool calls, SAM cuts the product out of her photos for flyers, and Muse Image creates flyer backgrounds. Voice notes are transcribed so she never has to type. It runs on the WhatsApp Cloud API, FastAPI and Postgres. Demo: Broadway Books, a real bookshop in Agbowo, Ibadan, with its real booklist and sales. Judges can open it in one tap at https://sabi-us.onrender.com.
