Sika
Built at Meta Global AI Developer Hackathon · Oct 26, 2026 · Remote

Sika is an investing assistant for the Ghana Stock Exchange that lives in WhatsApp, the app Ghanaians already use every day. Investing on the GSE today means a broker's form, a statement PDF and a lot of guesswork. The market is also thin: on the day I built this, GCB had buyers at GHS 39.00 and sellers at GHS 45.86, and most apps just show the last trade. Sika makes investing a conversation: - Gets to know you. Five quick questions build an investor profile. Like an adviser, Sika takes the lower of your willingness and your capacity for risk. - Builds a plan with you. Your goal, monthly amount and limits, set with a few taps. - Suggests trades that fit your plan. Each suggestion is priced from IC Securities' live order book, with every charge shown to the pesewa and a plain explanation. You can tap, type or send a voice note. - Leaves the decision to you. Sika never buys or sells. The AI can only suggest, and fixed code checks every suggestion against your plan before you see it: per-order and monthly limits, max in one stock, never-buy list, never sell at a loss, and that someone is actually on the other side. You place the order with your own broker and tap I bought it. Sika then keeps your holdings, profit after charges, monthly budget and price alerts up to date. Investors can also ask how the market is doing, get a deep dive on one stock, and compare stocks side by side. Comparisons cover the price, spread and real liquidity: how often it trades, and whether your amount fills at the best price. They also cover sector, size, dividend yield, P/E, latest results and recent news, plus how each stock fits the plan. Portfolio insights show sector mix, dividends over the last 12 months, and holdings that rarely trade. They get news with links to the sources, and can follow a stock: Sika messages them when there's important news on it. It sends at most one story at a time and never the same story twice. Voice notes work on the web page too, just like WhatsApp. Sika answers the way you ask. Write or speak in English, Pidgin, Twi, Fante, Ga, Ewe, Hausa or Dagbani and it answers in that language, with nothing to set up first. A first question gets answered before Sika offers to build a plan. A voice note gets a voice note back, plus the text with the exact numbers. Translation never changes an amount or a ticker: a line that would come out different is sent in English instead. Sika stays on topic. It only talks about investing on the GSE. Off-topic requests (other markets, homework, poems) and attempts to change its rules get a fixed reply written in code, so the model never answers them. Every suggestion is visible on a private activity page: the AI's reasoning, the order book, each plan check, and what you did.
