AI in EI — Full Reference home: five developmental domains
Field Guide · Motor 9–12 mo
The reality

You know this feeling.

You're sitting cross-legged in a family's living room. A toddler is climbing on you. The parent is watching. And you're trying to remember whether pincer grasp should be emerging at 9 months or 12, and what the red flags are for this age range.

You didn't go into Early Intervention to second-guess yourself. You went in to help kids and families.

AI in EI puts the clinical knowledge you need in your pocket — organized the way your brain actually works during a session.
What's inside

Good to know

What AI in EI is — and isn't.

The “AI” in AI in EI is the product name, not artificial intelligence. There's no chatbot, no auto-diagnosis, no machine learning making clinical decisions. It's a structured clinical reference tool — built by a clinician, for clinicians.

AI in EI is not…

  • An AI chatbot or diagnostic tool
  • A parent-facing milestone tracker
  • A replacement for clinical judgment or supervision
  • A documentation or billing system
  • A medical device

AI in EI is…

  • A structured clinical field guide for home visits
  • Peer-reviewed milestones, red flags, and activities by domain and age
  • State compliance checklists — Massachusetts verified, more states coming
  • Parent coaching scripts you can use on the spot
  • A tool that works the way your brain works during a session

No child data. No patient data. No tracking.

AI in EI collects no child data, no session notes, no patient information, and no personal health data. There are no accounts and no logins. The app works entirely on your device. Nothing leaves your phone. This website uses privacy-first, cookieless analytics to count page visits — no personal data is collected.

Two modes

One app, two shapes of attention.

Same domain. Same age. Different depth.

MOT, OTR/L · Early Intervention OT · Massachusetts · Since 2018

I'm an OT working in Early Intervention in Massachusetts. I built AI in EI because I was tired of fighting my laptop in living rooms — scrolling through dense reference materials while a parent watched and a toddler pulled at my screen.

I wanted a tool that works the way my brain works during a session: what am I seeing, what does it mean, what do I do about it, and what do I tell the parent. That's what the Field Guide does.

And I wanted a reference I could trust — built on actual state operational standards, not someone's best guess at what compliance requires. That's what the checklists do.

This isn't a generic milestone app for parents. It's a clinical tool built for the specific reality of EI work — built in Massachusetts, right for clinicians everywhere.

Founding Clinician Group

Help shape what comes next.

AI in EI is built by a clinician, and it gets better with clinician feedback. If you're working in EI — whether you're an OT, PT, SLP, developmental specialist, service coordinator, or supervisor — I want to hear what works, what's missing, and what would make this more useful in the field.

Join the Founding Clinician group and help shape what comes next.

No commitment. No spam. Just a clinician asking other clinicians what they need.

For agencies & supervisors

Give every clinician on your team a consistent field guide.

If you're running an EI program, you already know: onboarding takes months, compliance expectations keep shifting, and your clinicians are making dozens of fast clinical calls in the field every day.

AI in EI gives every clinician on your team a portable reference — milestones, red flags, compliance checklists, parent coaching language, and structured activities — organized by domain and age, built on verified state standards.

It’s not a replacement for supervision. It’s a field guide that makes supervision conversations more productive.
