FOUNDATION MODEL FOR UNDER-18 USERS

Why expect kids to use AI responsibly,why not build AI which behaves responsibly?

Most AI is built for adults. When children use it, we add filters, limits, and parental controls — but children are not “smaller adults.” They are still developing the reasoning, creativity, and perception of the world that AI can so easily weaken. dew is a child-facing AI that kids (under 18) can turn to — to learn, create, share, discuss, and find guidance — while protecting the very thinking that makes learning meaningful. Grounded in the Socratic method, it guides rather than hands over answers — free, safe by design, and open-source (coming soon).

Talking Through a Worry with Dew (with care)
For child

More than a coach. A partner in thinking. A companion.

Learn by thinking, not copying

Ask anything, any time. dew never rushes to answer. It helps a child build the habit of thinking, not just the habit of prompting.

Share & discuss, freely

A safe space to talk through ideas, curiosities, and worries — dew listens, responds at their level, and keeps the conversation non-judgemental.

Speaks a child's language

Fine-tuned on a curated corpus of age-appropriate material, so its vocabulary and pacing fit the child — not a corporate user — and adapt to grade level automatically.

Kids
Parents
For parents

Safeguarding without surveillance.

Alerts for serious risk

If a child shows signs of suicidal thoughts or violent ideation, parents are alerted immediately.

Private by design

No ads, no data harvesting, no behavioural profiling. We collect only the minimum, and your family's data is stored and processed in India — never sold, and never sent to or used to train any outside AI service.

A regular progress summary (coming soon)

Soon, parents will be able to receive a simple summary — learning progress, interests, and anything worth a conversation — so you can stay involved without watching over their shoulder. No tracking, no profiling.

For educators

AI you can finally allow in class.

Protects academic integrity

It won't generate passive essays or final answers, so assignments measure real understanding again.

Runs on what you already have

dew runs in the browser as a hosted service, so it works on the modest and shared devices schools already have — no downloads, no hardware upgrades.

Open by design (coming soon)

dew's weights, code, and methods will be released open-source under Apache 2.0, so institutions will be able to inspect exactly how it works and, in time, self-host it. Today it runs as a privacy-protective hosted service, with data stored in India.

Teachers
How DEW teaches

The Socratic method.

dew isn't adult AI with parental controls added later — it's developmentally aware by design. At its core is the Socratic method: a cooperative, question-and-answer style of teaching. Instead of providing answers, dew guides children to discover truths on their own — asking probing, open-ended questions that challenge assumptions, reveal contradictions, and build deep, analytical thinking. It knows when to answer, when to ask, when to simplify, when to encourage, and when to direct a child toward a trusted adult.

The kinds of questions it asks

Clarifying

“What exactly do you mean by that?” · “Can you give me an example?”

Probing assumptions

“How did you arrive at that?” · “What if this were the case?”

Exploring evidence

“Why do you believe this evidence is reliable?”

Examining perspectives

“How might someone on the opposing side view this?”

Testing consequences

“If your argument holds true, what logically follows?”

The result

The student becomes the active participant — thinking for themselves and building understanding that lasts.

How we built it ?

Fine-tuned on a curated corpus of age-appropriate material — so its vocabulary and pacing fit the child, not a corporate user.

By the numbers
9B
Parameters — a purpose-built model tuned end-to-end, not a prompt wrapper on someone else's chatbot.
<18
Age below which dew hard-refuses to dump finished answers, guiding Socratically instead.
In code
Safety is enforced in the system around the model — checks it can't be talked out of, even if the model is jailbroken.
Apache 2.0 (coming soon)
Weights, code, and methods to be released open-source on GitHub — inspect, self-host, and build on it.

Training pipeline

01 · Continued Pre-Training (CPT)

Initialises from a clean, open 9B base and fine-tunes on a curated corpus of age-appropriate material — so age-appropriate language is the model's natural output, not a filter bolted on afterward.

02 · Direct Preference Optimization (DPO)

Instils the Socratic, guide-first behaviour through supervised fine-tuning on curated example dialogues — multi-turn guiding inquiries, contextual hints, and conceptual milestones — so guiding before answering is the model's default.

03 · Logits-Level Security

Wraps the model in independent code-enforced safety - input and output moderation, always-on crisis routing, and deterministic answer-checking (maths is verified symbolically) — all enforced outside the model, so a jailbroken or mistaken model still meets limits it cannot override.

Research

DEW: Responsible AI, Built for Children

July 2026

This paper describes DEW, an open-weight AI assistant built for children; the evidence and international standards that shape it; and the architectural principles on which it is built. The foundation weights and training methodology will be released as open source on GitHub (coming soon), under the Apache License 2.0.

Our vision

It will be free forever

A child's mind should never be a business model. We will keep DEW free, forever — never gated behind a paywall, never sold. Our code, datasets, and methods will be released open-source under Apache 2.0 (coming soon), so anyone can inspect, host, and improve it.

This is how we deliver on our purpose of Responsible AI: not as a compliance exercise, but as the engineering philosophy that guides every model we build.

FAQ
What is Dew?+
Dew is a responsible AI for children. It helps with maths, general knowledge, and creative writing, teaching with the Socratic method — guiding with questions rather than simply giving answers — so children build genuine understanding.
Is Dew safe for my child?+
Safety is built into Dew and always on. Dew keeps to learning topics and gently declines the rest, its own guardrails help keep conversations age-appropriate, and it responds with care if a child appears to be in distress — sharing a helpline and notifying you. Dew is not a counsellor or a substitute for professional help or adult supervision.
How do sign-in and consent work?+
A parent or guardian (18+) sets up and controls the account and provides consent for their child. The minimum age to create a child profile is 5. We confirm that the parent controls their email address when the account is created, and consent can be withdrawn at any time.
What data do you collect?+
A parent's email; each child's first name and a grade or age band (we ask about age only to set the learning level — no birthdates); the messages exchanged during learning conversations; and limited technical information needed to run Dew. If a child uploads a photo, it is used only to understand the question and is not stored.
Where is my data stored — and do you use it to train AI or for ads?+
Your family's data is stored and processed in India and is never transferred outside India. It is never sold, never used for advertising, and never sent to or used to train any outside AI service. Dew's tutoring and safety technology is built and owned by Rainwater Labs.
