Who it's for
Solo builder or 2-person team targeting African language learners (English, French, Yoruba, Hausa) and diaspora communities willing to pay in USD for structured speaking practice
How to build it
1. Pick one high-demand language pair (e.g. English for Yoruba speakers, French for West African professionals). Interview 20+ potential users on their pain points with traditional tutoring—cost, scheduling, shame, access.
2. Build a basic web app with a voice input UI (use Web Audio API or Recorder.js), integrate a speech-to-text API (Google Cloud Speech or Deepgram), and wire it to OpenAI/Claude for conversational responses and corrections. Start with pre-scripted dialogues (ordering food, job interviews, casual chat).
3. Launch a closed beta (50–100 users) on Discord, Reddit language communities, and LinkedIn. Charge $5–10/month (intentionally low). Collect video testimonials and usage data.
4. Build a feedback loop: track which dialogues drive retention, which prompts learners get stuck on, and what correction style (harsh vs. encouraging) converts to paid. Iterate the curriculum wee

Your edge as a builder from anywhere
Nigerian builder understands Africa's language learning pain—poor internet, no access to native speakers, tutors cost ₦3k–10k/hour. You can price 50–70% below Western tutors, use local payment rails (Paystack, Flutterwave), and serve diaspora at scale in USD. Speed to market and willingness to iterate on non-English languages (Yoruba, Igbo, Twi) that Western AI tutors ignore is your moat.
