The AI learning companion that actually knows your child.
Cognaa pairs adaptive mastery tracking with an agentic tutor that remembers how your child thinks — so every explanation clicks, every quiz fits, and every parent finally sees real progress.
One-size-fits-all doesn't fit anyone.
Most "AI tutors" are thin wrappers over a chatbot. They don't know where your child got stuck yesterday, don't track real mastery, and can't tell the difference between a careless slip and a misconception that needs fixing.
Adaptive mastery, not percentages
Every answer updates a Bayesian model of what your child truly understands. No cramming, no false "100%" — just honest, temporal mastery on 2,000+ concepts.
BKT · temporal decay · prereq-awareA memory that remembers
Cognaa's temporal knowledge graph holds your child's learning history — preferred analogies, stuck points, style of explanation that clicks. Every session builds on the last.
Graphiti · episodic + semanticScaffolded like a great teacher
4-level Zone of Proximal Development scaffolding. The AI meets your child just past what they can do alone — prompts, not answers. That's where real learning lives.
ZPD · Vygotsky-alignedMulti-modal by default
Your child snaps a photo of their handwritten work. Cognaa reads it, finds the exact step they went wrong, and explains — in the way they learn.
Vision · handwriting · HEICNever-repeat quiz engine
Memory-augmented generation guarantees less than 15% similarity between consecutive quizzes. Goodbye, same-questions-different-day.
Anti-repetition · PNAS 2025-backedBuild your own AI skill
No prompt engineering. Describe what you want — "SAT Math drill", "Spanish conversation partner", "Great Books Socratic coach" — and Cognaa builds it, tuned to your learner.
Skill Builder · no-codeNot a chatbot. A teaching system.
Under the hood, Cognaa orchestrates a team of specialist agents against a living model of your child's mind. Here's what happens in every session.
A tutor that sees the whole learner
Your child types, speaks, or photographs their work. Cognaa parses it all — using vision for handwritten math, semantic search over their history, and real-time mastery state from the learner graph.
- Multi-modal input
Text, voice, photos of handwritten work — all first-class. - Memory retrieval
Pulls relevant history: past mistakes, favorite analogies, what clicked last time. - Mastery state
Knows exactly which prerequisites are solid — and which are shaky.

Agentic reasoning, not autocomplete
A ReAct-style agent picks the right specialist tool for the moment — from writing assessment to curriculum mapping to quiz generation. Every step is traced, auditable, and adaptive.
- 8+ expert agents
Learning coach, writing assessor, curriculum mapper, Socratic tutor, and more. - 43+ specialist tools
Gated by age, grade, and plan — always the right tool for the learner. - Full transparency
See what the AI did, step by step. No black box.
Explanation tuned to one specific learner
The prompt compiler assembles a response from your child's style, grade, mastery, and session history. Scaffolded one level past what they can do alone — never just handing over the answer.
- Personalized prompts
26+ educator-validated prompt templates, versioned and A/B tested. - Standards-aware
CCSS, TEKS, CBSE, state-specific — pick what matters to your family or school. - Spaced review, built in
FSRS schedules the next touch-point so skills stick — not cram & forget.
Current focus: fractions w/ unlike denominators. Prerequisite mastery on equivalent fractions = 0.92. Stuck last session on common denominator (BKT p(know)=0.41).
ZPD level: L3 — hint + scaffolded guide. Use fraction bars or color tiles; avoid symbolic-only notation. Recall past analogy: "pizza slices" resonated Tuesday.
Tone: encouraging, playful, under 60s.
Teach the way your family actually believes.
Most AI tutors come with a hidden ontology — a set of unstated assumptions about what's real, what matters, and whose story to tell. Cognaa is the first AI education platform that lets you choose — at an ontological level, not a surface one. Catholic classical, Christian classical, Hispanic heritage, Indian heritage, or neutral secular. Set one for your family. Set another for each child.
None
Secular Default
secular
Standard academic approach. Rigorous, neutral, evidence-based — the default if you don't want worldview framing at all.
Catholic Classical Education
faithThomistic classical education rooted in Catholic intellectual tradition. Faith and reason as "two wings" — Fides et Ratio.
- Sacramental worldview & natural law
- Church Fathers, Aquinas, Pope Francis
- Theistic evolution per Humani Generis
Classical Christian Education
faithTrivium-based — Grammar (K-4), Logic (5-8), Rhetoric (9-12). Biblical worldview as the integrating thread across subjects.
- "All truth is God's truth"
- Dorothy Sayers & Susan Wise Bauer
- Charlotte Mason narration pedagogy
Hispanic Heritage Education
culturalFamily-centered, bilingual/bicultural. Rooted in familismo, respeto, and being bien educado — academically excellent and morally grounded.
- Pre-Columbian heritage & mestizaje
- Natural Spanish–English bridge
- Pan-Hispanic contributions to civilization
Indian Heritage Education
culturalHolistic education rooted in Bharatiya Jnana Parampara. Vedic wisdom, gurukula pedagogy, and Indian contributions to world civilization — integrated with modern curriculum.
- Dharma · artha · kama · moksha
- Vasudhaiva Kutumbakam — "the world is one family"
- Aligned with India's NEP 2020

The things parents ask us most.
What ages is Cognaa for?
Cognaa is designed for K–12 learners, with the deepest mastery coverage currently in K–8 Math. New subjects (ELA, Science, Writing) are rolling out through the CBSE framework packs and Common Core / state standards.
Does it replace our curriculum?
It doesn't have to. Use Cognaa as a full adaptive curriculum, as a supplemental tutor alongside what you're already doing, or as an after-school skills booster. Parents and educators choose the standards frameworks that matter (CCSS, TEKS, CBSE, state-specific).
How is this different from ChatGPT?
ChatGPT has no idea who your child is. Cognaa does. We maintain a temporal knowledge graph of each learner, a Bayesian mastery model over 2,000+ concepts, and an agentic orchestration layer with 43+ specialist tools. Every response is personalized to the one child in front of it.
Is my child's data private?
Yes. Children's accounts are parent-governed with age-appropriate safeguards, minimal data collection, and the ability to export or delete at any time. We never sell data and never train on children's conversations.
Can I trial it before paying?
Absolutely. Start free at app.cognaa.ai — no credit card, set up in minutes, explore the full product with your child.
