The  platform

One OS. Any body you can build.

PlayOS is not one fixed product. Voice-first companions that talk, see and play. Baby care that monitors, soothes and learns sleep. We tune the module and the AI to the experience you're selling, then ship it under your brand. Here is exactly how it works, under the hood.

One operating system for everything a child holds. You build the body. PlayOS brings the soul.

Choose  the experience, and the module price follows

Two experience families. Six tiers. One module.

Per-unit pricing at design-partner volumes, in USD (₹ quotes for India programs on the call). The exact number lands on your spec call: it moves with options and order size, not with our mood.

The  parent app

Parents see everything. That's why they keep it.

Every PlayOS product ships with a parent app you put your own brand on. It is how a parent knows the toy is helping, not just talking, and it is the reason they renew, month after month.

Summary & notifications

An actionable summary of the day, and a nudge the moment something matters.

Conversation log

Every conversation, in full. Parents read exactly what their child talked about, anytime.

Filter topics

Parents choose what the toy talks about, and what it never will.

Reinforce cultural values

Ask the toy to weave a family's language, culture and values into play.

Parenting philosophy, in one prompt

Align the companion to how a family parents, in a single line of text.

The  one-prompt difference

Parent it your way, in one line.

A parent types how they want their child guided, and the toy follows. Ask it to make patience the lesson, with the child as the hero of the story. Their values, their culture, their words.

Tell stories where patience wins, and make my child the hero.
From  play to the real world

It turns curiosity into a next step.

A morning spent talking about birds becomes a suggestion to visit the bird sanctuary this weekend. The app surfaces the real-world moment the conversation opened up.

birdsvisit the bird sanctuary

The parent app ships with every PlayOS product, branded as yours.

The  voice path, end to end

A child speaks. The toy answers. Here's the path in between.

01

Wake, or press

The device listens only on a wake word or a button. The rest of the time the mics are off. Better for privacy, better for battery.

02

Capture

The mic array picks up the voice, and on-device voice-activity detection trims the silence before anything travels.

03

Edge or cloud

Light turns can run on the module itself. Richer turns route to the PlayOS cloud. The same firmware decides, per device, per tier.

04

Voice to voice

The Voice SLM goes from voice straight to voice, with no text round-trip in the middle. That is what keeps a reply quick enough that a three-year-old doesn't lose interest.

05

Safety on every turn

On-device filters and cloud guardrails screen what goes in and what comes out, grade the answer to the child's age, and keep it off the open internet.

06

Answer

The toy speaks back in the child's language, remembering what was said a minute, or a week, ago.

Exact latency targets are spec'd to your tier and hardware on the call.

Under  the hood

The full stack. You drop in one module.

Six things stand between a child and a bad answer.

The smaller the brain, the smaller the blast radius. A sub-1B model has far less surface to go wrong than a frontier one, and it never talks to the open web.

The Voice SLM: the voice brain, as an API.

A sub-1B-parameter voice-to-voice model (no text in the middle), built for the latency and edge constraints of real toys, not datacenter assumptions. Partners get access from Q4 2026.

Training data comes only from conversations families separately opt into: anonymised, withdrawable with one tap, never sold. Every consented conversation makes the model smarter.
