Hi, I'm Tomas Morales
I'm building the future of education with Arbor Learning — an AI-powered PreU that turns a diagnostic into a personalized mastery path. 10+ years shipping products, now focused on helping students succeed.
About Me
Education in Chile is broken for too many students. Traditional PreUs deliver the same content to everyone, ignoring each student's unique gaps. I saw this problem firsthand — and after 10 years shipping 50+ products as an engineer and CTO, I decided to fix it. Arbor Learning is a digital PreU powered by AI that diagnoses where each student stands and builds a personalized mastery path. With 10k+ validated questions and 200+ lessons per subject, we're making PAES preparation truly adaptive.
What I Believe
“Great teams build fast because they trust deeply.”
“Impact, clarity, and the craft of building matter most.”
“Work should feel like flow, not friction.”
When I'm not building Arbor, I'm surfing, cycling, or splitboarding in the Andes.
How Arbor Works
A smarter path to PAES mastery — personalized, adaptive, and AI-powered.
Diagnostic
Students take a diagnostic test that maps their strengths and gaps across every skill in the subject.
Personalized Path
Arbor builds a custom learning path based on each student's unique weaknesses using a granular skill tree.
Adaptive Practice
Micro-lessons (10–20 min) with worked examples and immediate practice, adjusting difficulty in real time.
Mastery
Spaced repetition and interleaving ensure long-term retention. Students advance only when they truly understand.

AI Won't Steal Our Jobs — It'll Give Us Our Time Back
AI is already taking repetitive work off our hands. But something different comes with it—AI makes people incredibly productive. What if we finally reach a point where work stops consuming our whole life?

Ship Faster by Knowing When NOT to Use AI
The fastest way to real impact with AI isn't a clever prompt — it's knowing where AI excels, where it fails, and where to go deterministic. Use strong exemplars, a stable spec, and ruthless validation.

The Truth About AI Engineers (From an ex-CTO)
AI hasn't made learning easier for engineers—they just face different lessons now. The best engineers today use AI as a force multiplier, not a crutch.
