Volume
Grow into a lower rate — automatically
Discounts apply on their own as monthly usage climbs — like cloud infrastructure. No renegotiation.
Telephony is pass-through at provider cost. Margin is on inference we run — never on carrier minutes.
À la carte
Four primitives. Compose your own.
A fintech IVR or health hotline doesn't need the tutor — use African-accent STT or Nigerian voice on their own.
transcribeAfrican-accent speech-to-text
Nigerian English, Pidgin, names, money, numerals — accurate on noisy 2G phone audio.
speakNigerian text-to-speech
Warm, local voices in English, Yoruba, Hausa, Igbo & Pidgin.
tutorCurriculum LLM turn
Adaptive, safety-first tutoring turns grounded in literacy & numeracy.
identifyPer-child identity on a shared phone
Recognise and remember individual learners across calls on one household number.
One call. The whole pipeline.
Send audio in, get audio back — tuned for Nigerian voices and noisy 2G lines.

}'Cheaper — and the only one built for Africa
Vapi and ElevenLabs are excellent for American English. None of them understand a child speaking Pidgin on a 2G line.

Questions, answered
What exactly am I paying for?
The inference we run — speech-to-text, the language model, and text-to-speech. Telephony minutes are passed through at cost as a separate line item. We never mark them up.
How does a minute get counted?
You're billed per minute of active conversation through the pipeline, rounded to the second. The first 1,000 minutes every month are free.
Do volume discounts need a contract?
No. Lower rates apply automatically as usage crosses each threshold. Enterprise commits (from $0.015/min) are the only ones that need a conversation.
Can I use just transcription or just the voice?
Yes. Each primitive is available on its own — fintech IVR and health hotlines don't need to pay for the tutoring layer.
Why are you cheaper than Vapi and ElevenLabs?
We own the hard part — African-accent models — and refuse to make margin on telco minutes. Same pipeline that teaches kids on a phone call.
Not a developer?
Sabi for Organizations
Governments and NGOs: fund a cohort, kids learn by phone call. We handle telephony, curriculum, AI, and impact measurement.
