Ayo is a free phone line that children can call. A warm voice answers straight away, any time. It listens without judging, never rushes, and never asks “why”.
When a child shares that someone is hurting them, Ayo makes sure it isn’t lost: their words go to a trained person whose job is to keep children safe. Ayo works on any phone, with no app, no internet, and no smartphone needed.
Ayo is the “little sister” of Sabi, E4E’s AI voice tutor that teaches Nigerian children maths and reading over ordinary phone calls. Ayo uses the same phone technology, pointed at listening instead of teaching. Ayo is honest with children that it’s an AI.
Four steps, one phone call.
A child calls
On any phone, even a basic one. A warm, calm voice answers.
Ayo listens
Like a kind older sister. Short sentences, never rushing, never blaming. A child can talk about anything; they don’t have to be in crisis.
Ayo understands
In the background, Ayo recognises when something may be wrong, even when a child says it indirectly — “I don’t like going home”, “sometimes I don’t get dinner”.
A human follows up
Anything concerning goes to a trained person to review. In an emergency, Ayo tells the child the local emergency number.
Built for the child who has no one else to tell.
Answers instantly, 24/7
No queue, no hold music. A warm voice picks up straight away, day or night.
Works on any phone
An ordinary voice call: no smartphone, app, or data. This matters where most children don’t have smartphones.
Listens like a person, not a form
Trauma-informed: believes the child, never asks “why” or for graphic details, lets the child set the pace, and is honest that it’s an AI.
Hears what isn’t said outright
Recognises many kinds of harm, not just physical — emotional abuse, neglect, threats, bullying, and “I’m scared but I don’t know how to say it”.
Knows where to send help
Asks gently where the child is. If it’s safe, it can send a one-tap link so the child’s phone shares its location.
Gets it to a human
Concerns become review items for a trained reviewer, with the child’s own words as evidence and a clear reason why.
AI listens. Humans decide.
Trust is the whole product. These are the rules Ayo is built on.
A person decides, not the AI
Ayo’s AI only understands the conversation. Separate fixed rules, plus a trained human reviewer, decide what happens. The AI can’t close a case or decide a child is fine.
Nothing slips through
If Ayo isn’t sure, it sends the conversation to a human rather than ignoring it. “Not sure” never means “nothing happened”.
The child’s words, not guesses
Every concern shown to a reviewer quotes what the child actually said.
Honest with children
Ayo never promises total secrecy. It tells children what they share goes to someone whose job is to keep them safe — and never to the person hurting them.
Minimal data
Names, phone numbers and emails are removed from transcripts before they’re saved. Location stays in the secure case-review system, with the trained reviewer, not in alert messages.
Never promises rescue
Ayo won’t say “help is on the way” unless that’s true. In danger it gives the child the real local emergency number.
Most children who are hurt never tell anyone.
Many are hurt by someone at home, so speaking up isn’t safe. Helplines are overstretched. Many children have no smartphone, no data, and no trusted adult. A child should only need a phone call.

Child Helpline International, 2024Children are usually hurt by someone they know — of child sexual assault victims reported to US police, 93% knew the perpetrator. That is why speaking out at home is dangerous, and why a line a child can reach on their own matters. US BJS, via RAINN
Built by people who grew up where it matters.
Education for Equality (E4E) is a US 501(c)(3) nonprofit, registered with Nigeria’s CAC. Founder Naomi Ivie (Wesleyan University, Economics & CS) grew up in Lagos.
Sabi, E4E’s AI voice tutor, already teaches foundational maths and literacy to Nigerian children over ordinary phone calls. Ayo runs on the same proven telephony stack: phone line → audio bridge → real-time voice model.

Talk to Ayo Now
Ayo is answering calls on a demo line at HackPrinceton this weekend — find the E4E table to hear it live. A public number for children launches once our safeguarding rules have been reviewed by child-protection professionals.
Where Ayo is today
Ayo is a working prototype built at HackPrinceton (Nov 13–15, 2026). It is not yet a live service for children. Live phone calls, in-call location sharing, concern review, and human case review work today; escalation rules are a demo policy that needs review by child-protection professionals before real use.
