Helping children with autism communicate, learn, and grow.
Caju is a gamified companion for children with autism: Augmentative and Alternative Communication (AAC) boards to express needs, visual routines for daily life, tracing practice for letters and numbers, calm picture stories for new moments, and a community for the people who care.
Card required. Nothing is charged until the trial ends.
A safe space for communication and routines
Caju is a support tool for children with autism. It does not diagnose or treat. It gives professionals and families clear, consistent ways to help a child express themselves, learn daily routines, and feel proud of what they did today.
Communicate
Picture-based AAC boards your child can tap to make themselves heard.
Learn routines
Step-by-step visual schedules for mornings, school prep, hygiene, meals.
Practise writing
Trace letters and numbers on the screen, at the child's own pace.
Put things in order
Arrange pictures, numbers and letters in the right order.
Feel prepared
Calm picture stories that help a child get ready for the dentist, a haircut, or bedtime.
Celebrate progress
Stars, badges and warm parent reports. Never punishment.
Connect with others
A warm space where families and professionals share what works and cheer each other on.
AAC boards your child can actually use.
Tap a tile to hear it. Each tap speaks the word out loud. Customise tiles for your home, school, or therapy setting, without losing the simple, kid-safe feel.
Visual routines that turn mornings into wins.
Step-by-step schedules with pictures and warm prompts. The child sees what's next, taps to complete, and earns a reward at the end. Never punished for stopping.
Calm picture stories for everyday moments.
Build a gentle, personalised story to help a child feel ready for things like the dentist, a haircut, or going to sleep. Pictures and soft narration, made in minutes. Every story is yours to review before a child sees it.
A community that gets it.
Swap experiences, ask questions, and celebrate small wins with other families and professionals. Friendly, moderated, and free of clinical jargon, so you never have to figure things out alone.
A dedicated hub for the people who care.
One place to track stars, badges, and routines completed today. Sessions become warm reports parents can read in two minutes: no jargon, no clinical scoring.
Open library
See the whole library before you decide
Hundreds of picture communication boards, visual routines, sequences and picture stories. Looking costs nothing. Using them with a child and printing to PDF come with the plan.
Picture communication boards (AAC)
Boards of picture symbols by theme, so a child can point to what they want to say.
ExploreVisual routines
Everyday tasks split into picture steps, so a child knows what comes next.
ExploreVisual sequences
Pictures, numbers and letters for a child to put in the right order.
ExploreHow it works
From setup to a session your child can actually use, in four short steps.
- 1
Create a profile
Tell us about the child. The therapist usually does this first.
- 2
Build or pick content
Use a template, customise tiles, build a routine. Or start from one of ours.
- 3
The child uses it
A simple, kid-safe interface. No timers, no fail states, big buttons.
- 4
Share the progress
Sessions become warm, jargon-free reports for parents, automatically.
I really hope this project goes far and helps families, especially children.
