A companion, not a screen

A friendly robot-scientistin your kid's pocket.

Doctor Circuit is a small handheld device that lets your kid talk to a kid-safe AI companion — anywhere. Cellular built in. Parents see every conversation and can step in by voice any time.

Built by a parent, for parents. Currently in family beta.

Designed for how kids actually live

A real pocket friend, with real guardrails.

Kid-safe by default

No self-harm, no violence, no adult content. No hidden recording — mic only when they press to talk.

Works without Wi-Fi

Cellular built in. In the car, on walks, at grandma's — Doctor Circuit just works.

You see everything

Live transcripts, wellbeing alerts if a conversation goes somewhere it shouldn't, and voice drop-in any time.

Different personas

Doctor Circuit for curious chats. Doctor Ninja for bravery and movement. New characters without a new device.

How it works

Three minutes to set up. Rest is up to them.

1

Pair the device

Create a parent account, enter the 6-digit code from the device. Done in under a minute.

2

Give it to your kid

Push-to-talk button. They ask questions, tell stories, get silly. Age-tuned voice, friendly refusals.

3

Stay in the loop

Read transcripts, drop in by voice, leave a recorded bedtime story. Alerts if something feels off.

The safety promise

  • · No self-harm, violence, sexual or adult content — refusals are gentle and in-character.
  • · No real addresses, phone numbers, or URLs ever reach the kid.
  • · Mic only records on push-to-talk. No always-on listening.
  • · Every conversation is logged and moderated. You see it all.
  • · Per-kid controls — Sara can do things Zev can't, and vice versa.

Questions you might have

Good questions.

Is my kid's data safe?

Transcripts live on our server (Fly.io, US). Only you can read them. No ads, no third-party resale. Moderation runs against OpenAI's omni-moderation model — flags stored with the transcript so you can review.

What age is this for?

Designed with a 5- and 7-year-old in mind. Personas have min_age hints; content stays age-appropriate. Parents gate every mode.

Does it replace me?

No. It's a companion, not a substitute. Parent voice drop-in is deliberately one button — kids hear you over Doctor Circuit any time.

What if I want my kid to stop using it?

You control when it's active. Unpair it, put it on a shelf, or limit it to bedtime story mode only.

Ready when you are.
