Every kid has things they want. These tools help them say so.

Free software for children who communicate in different ways: built by a dad, shaped around his daughter, and shared with your family. It runs on your own device, and it's free to use.

Our story

Every kid should get to choose what they wear.

Our daughter Ellie is six. She has Rett syndrome, which makes communicating verbally challenging for her. Through our communication work together, we discovered she was really interested in fashion. Like any young kid, she wants to pick out what she wears.

So we designed exactly that. Every morning her wardrobe shows up on screen, checked against the weather, and she chooses.

She started picking her own outfits every day.

It was one small win, and it gave her a reason to engage with her eye-gaze device: something she actually cared about. That's what all learning is, really: finding the things you care about and building from there.

Since then we've kept building: more ways to choose, make, write, and say.

The tools

Works out of the box. Take only what you want.

Each tool installs on its own and runs entirely on your computer, by eye gaze and by touch. They ship exactly as Ellie uses them every day.

Make it yours

Your kid's obsession is different. That's the point.

These tools weren't personalized after the fact. They grew up around one particular kid. Yours might not care about dresses. Maybe it's dinosaurs, or elevators, or a very specific cartoon dog.

This is the part we're most excited about: with today's AI coding assistants, you don't have to be a programmer to reshape these tools around your child.

1 · Use them as-is

Totally legitimate. Install, answer two questions, done. Many families won't need anything more.

2 · Swap in your kid's world

Your photos, your words, your books. Every tool is built to carry your family's content.

3 · Shape the software itself

Point Claude Code, Codex, or any AI agent at our repositories (they are written to be read by one) and describe the change in plain English. Then test it with your kid; they're the only reviewer who counts. See the builders track.

Local-first, honestly

Your child's world stays home.

Who's behind this

Days: medicines. Nights: software.

I run a biotech company working on treatments for Rett syndrome. In my former life I built software, so I couldn't help but try to use the technology we have today to give my daughter more ways to communicate, more ways to share what she wants, and more ways to learn. The tools are there.

After a while, people around us thought these could help other kids too. So I'm making them available, free.

We'd love your ideas, your pull requests, and someday your own tools in this collection.

If you'd like to help

Two ways, both optional.

Support the work

The software is free, forever. We're working on setting up a nonprofit; in the meantime, any money given here goes to fund Rett research, one way or another. Plain talk: until the nonprofit exists, contributions aren't tax-deductible.

For investors

Uncommon Therapeutics is a for-profit biotech developing treatments for Rett syndrome. Accredited investors interested in learning more may get in touch.
