An AI reading app for kids, without a chatbot
In Peabody, AI writes and checks stories; your child never chats with it. What the AI does, what plain code does instead, and why that split is safer for kids.
Peabody (peabody.kids) is an AI reading app for kids in which the child never talks to the AI. An AI model writes short stories from the child's ideas, at their reading level, and AI screens check those stories for safety. Everything else, from measuring reading level and tracking words to math and Peabody's own friendly lines, is plain code. There's no chat, no messaging and no microphone. It's free through the end of 2026.
A lot of parents are wary of "AI for kids," and they're right to ask questions. This post lays out exactly where AI is used in Peabody and where it isn't.
Why no chatbot?
A chatbot is the most obvious way to put AI in front of a child, and the hardest to make safe. An open conversation can go anywhere. It's hard to screen in advance, it can feel like a friend in ways that aren't healthy, and it invites a child to type personal things.
So Peabody doesn't have one. The idea box is one-shot: the child's ideas go in, a story comes out, and that's the end of the exchange. Peabody the mascot, a bubble dog in round glasses and a red bow tie, talks in short lines, but they're written ahead of time and picked by code. He can't be asked a question, and he can't answer one.
Where Peabody uses AI
| Job | Done by |
|---|---|
| Writing a story from a child's ideas | AI (Claude Haiku, from Anthropic) |
| Screening a child's ideas before writing | Code, then an AI classifier, with a stronger model's second opinion before turning an idea away |
| Screening every finished story | Code checks, then an AI screen, with a stronger model's second opinion when it isn't a clear pass |
| Comprehension questions for a story | Written with the story by the AI, then checked |
| An occasional quality review of a family's stories | A stronger AI model, read only by that family's grown-ups |
Every AI call is budgeted and counted against the child it was for, so Peabody stays affordable enough to be free.
Where Peabody uses plain code instead
| Job | Done by |
|---|---|
| Measuring a story's reading level | Code: published readability formulas, sentence length and word lists |
| Tracking which words are sticking | Code: cold warm-ups, three right days in a row |
| Choosing which words come back, and when | Code: a spaced schedule, missed words first |
| Peabody's lines, praise and jokes | Templates written ahead of time |
| Math problems and marking | Code, from a seed: no AI at all |
| Idea bubbles on the make page | A hand-written list of more than 670 ideas |
| Reading aloud | Your browser's built-in speech |
Using code wherever it can do the job is cheaper, more predictable, and easier to check. A formula gives the same answer every time; a model might not.
What "AI reading" means for your child, day to day
A typical visit looks like this:
- Open the library or make a story. The library has Peabody's own stories from Pre-K to 8th grade. Making a story takes a few taps.
- A quick word warm-up, cold, before the story (skippable).
- Read the story. Tap a new word to hear it. In the evening, an optional bedtime mode goes warm and dim.
- A short word check and four to six questions (also skippable).
- Read it to someone, in big type, if they made it.
- Stop. The session ends with a clear finish, not an endless feed.
The AI is behind step 1. Everything else is designed to be simple, predictable and the same for every child.
Peabody never listens
Some reading apps use the microphone to hear a child read and score their fluency. Peabody doesn't. There's no microphone and no recording, ever. That means it can't measure how fluently your child reads, and we say so plainly. It also means there's no recording of your child's voice anywhere. The best listener for a child reading aloud is a person in the room. See why your child reading aloud to you matters.
Is AI good for kids' reading?
It depends on the job. AI is very good at one thing reading practice has always needed: lots of fresh, interesting text at exactly the right level. A child who loves dragons can have a dragon story at a 2nd-grade level tonight, with the words they're working on inside it.
What AI isn't good at is being a teacher, a friend or a judge of a child. Peabody doesn't ask it to be any of those. It writes, it gets checked, and the rest is up to your child, you, and some carefully plain code.
Nothing about Peabody itself has been studied in a trial yet. What it's built on, like spreading practice over several days, comes from memory research, and we're careful to describe it that way. See a little every evening beats a Saturday cram.

Questions parents ask
Does my child talk to an AI on Peabody?
No. Children never chat with an AI or with anyone. They give ideas for a story once, and the AI writes it. Peabody the mascot's lines are written ahead of time.
Which AI model does Peabody use?
Stories are written by Claude Haiku, a model from Anthropic. Safety screens use Haiku with a stronger Claude model as a second opinion.
Does Peabody listen to my child read?
No. Peabody has no microphone and records nothing. It can't measure fluency; a grown-up listening can.
What does the AI know about my child?
Only what it needs to write a story: the ideas, the reading level, the practice words, the mood and the scariness ceiling. For a child without an account, that includes no name.
