Learn for real.
AI runs the session by asking questions, and measures what you actually absorbed.

ChatGPT gives answers. Leazons asks questions.
Same doubt, two paths. One ends in five seconds; the other shows up on the test.
Ordinary chatbot
Photosynthesis is the process by which plants convert sunlight, water and carbon dioxide into glucose and oxygen, inside chloroplasts, using chlorophyll...
You read it. Tomorrow it's gone.
Leazons
What do you think the plant needs to produce energy?
You answered. That's what sticks.
Built for the whole study loop
Student, parent, tutor — each with their own dashboard and the right information.
For the student
High-school to early-college students and exam-prep adults. Study with the material you already have; the AI asks questions instead of giving answers and measures what you actually absorb.
For the parent
Separate dashboard with the child's real progress, automatic alerts when they stop studying before an exam, and a weekly email — without ever reading the conversations.
"Hasn't studied for 3 days and has an exam Friday." "Low score despite time invested." "Improved 40% this week." Email in the parent's language.
For the tutor or specialist
Always freePsychologists, learning specialists and tutors follow the student, upload materials and see the learning profile. Always free.
In 3 simple steps
Send your material
PDF, text, a photo of your notes, or a YouTube link. Whatever you already have — you don’t need proprietary platform content.
Multi-format and multilingual
PDF, image, YouTube video with automatic transcript and text. Interface and reports in PT, EN and ES.
The AI runs the session
Progressive questions using 5 evidence-backed teaching techniques. It never gives direct answers — it guides you to discover them yourself.
5 techniques research supports
Segmented reading
Content split into blocks with immediate checks before you move on.
Feynman method
“Explain it like I’m 10.” Surfaces what you truly understand vs what you memorised.
Active recall
Without peeking at the material — pull it from memory. Just like a real exam.
Elaborative interrogation
Not just “what” — ask “why” and “how”. Builds deeper, longer-lasting connections.
Adaptive Pomodoro
Short sessions with breaks. Spots distraction and suggests rest at the right time.
All together, guided by AI
The AI picks which technique to use at each moment, adapting to your pace and how you respond.
Where the evidence comes from
Content split into learner-paced segments beats continuous presentation — 10 out of 10 experiments, median effect size 0.79.
Mayer, segmenting principle · Multimedia Learning
On tests taken days later, retrieving from memory retained substantially more than rereading the material.
Roediger & Karpicke · Psychological Science, 2006
Meta-analysis of 839 assessments across 317 experiments: spaced review beats massed practice.
Cepeda et al. · Psychological Bulletin, 2006
Self-explanation and elaborative interrogation were rated moderate utility in the review of 10 study techniques — below practice testing and distributed practice, both rated high.
Dunlosky et al. · Psychological Science in the Public Interest, 2013
Pomodoro is time management, not a lab finding: we use it to apply the spacing above, not as a technique with evidence of its own.
See what you absorbed
A real absorption score from your answers, a map of topics mastered and gaps, and reviews scheduled automatically.
Knowledge map
Every topic colour-coded by level: solid, fragile, gap, not studied. You see what needs attention without having to look for it.
Spaced repetition
Solid concepts come back at longer intervals; fragile and gap topics come back sooner. The reminder names the topic that needs review.
Pre-exam mode
Register the date and materials of an exam. The AI prioritises weak topics, schedules a D-1 session and generates a mock exam with answers.
Learning profile
Discover when you perform best, which format you absorb most (PDF, video, image, text) and how your absorption is trending in the last fortnight.

From people using it
“I never knew whether my son had studied enough for the test. With Leazons I can see how much of the content he actually absorbed, and that helps me a lot.”
Founder of Leazons and parent of an 11th-grade student
“I noticed an improvement in how much of the content my son absorbs after he started using Leazons. And I thought it was fantastic that the score Leazons generated came out very close to his actual test result.”
Parent of an 11th-grade student
Frequently asked questions
How is this different from ChatGPT?
Very. The goal isn't to explain — it's to test whether you actually know, guiding you to find the answers yourself. In practice: you don't leave a session with a summary, you leave with a score of what you absorbed and a map of what's still missing.
Does it work for any subject?
Yes. Send your material — PDF, text, image, or YouTube — and the AI adapts. Biology, history, maths, law, exam prep. Anything.
How do parents follow their child?
The Family plan includes a separate parent dashboard with sessions studied, absorption score, topics mastered and gaps — without access to the child’s conversation content.
What happens after the free month?
You can continue on Student for € 12/month or Family for € 19/month. If you do nothing, the account stays active but without access to new sessions. We will never charge without your consent.
Is my child’s data safe?
Yes. Data is stored on servers in the European Union and handled under Brazil's LGPD (Law 13.709/2018), never sold to third parties. Parents only see the progress summary — not the chats. Full details in the Privacy Policy.
