How Cognaa works.
Cognaa is not a chatbot with an education prompt. It's a teaching system — a learner graph, a memory layer, an agentic orchestrator, and a skills engine — all designed to adapt to one specific child.
Learner Graph
A temporal knowledge graph of every concept your child has touched — what's mastered, what's shaky, what's next. Updates continuously as they work.
2,000+ KCs · Bayesian · prerequisite-awareMemory Layer
Episodic + semantic memory remembers how your child learns — favored analogies, past mistakes, style that clicks. Every session gets more personal.
Graphiti · Cerebe memory servicesAgentic Orchestrator
A ReAct-style reasoning agent with 43+ specialist tools and 8+ expert agents — picks the right approach for the exact moment your child needs help.
LangGraph · 8 agents · 43 toolsMeta-Learning Coach
ZPD-scaffolded prompts land just beyond what your child can do alone. FSRS spaced repetition makes skills stick, not evaporate.
ZPD (Vygotsky) · FSRSMulti-Modal Input
Typed questions, voice, photos of handwritten work — all first class. Vision model reads messy 4th-grade handwriting and finds the exact step that went sideways.
Vision · voice · HEICSkill Builder
Create your own AI skill in plain English — "SAT drill", "Spanish conversation partner", "Great Books Socratic coach". Cognaa writes the manifest, picks the tools, tests it for you.
No-code · conversationalWhat happens when your child asks a question.
From the moment your child taps "help," Cognaa runs a multi-step perception → reasoning → response loop — in under a second of perceived latency, with every step traced and auditable.
Perceive
Parse text, image, or voice input. Retrieve relevant history from the memory layer. Read current mastery state from the learner graph.
Reason
Agentic orchestrator picks the right specialist (writing, math, curriculum, Socratic…) and the right ZPD scaffolding level for this exact moment.
Respond & Update
Streams a scaffolded, personalized response. Logs the interaction. Updates BKT mastery. Schedules spaced review via FSRS for lasting retention.
What students see. What adults see.
A workspace that meets them where they are.
Instant, kind explanations in their preferred style. Interactive canvas for worksheets & assessments. Smart starters that suggest the right next thing to practice. Grade-aware tool palette — always appropriate, never overwhelming.
Dashboards that mean something.
Daily digest: one insight, one action. Mastery trends by concept and unit. Misconception alerts the moment they appear. Chat with Cognaa about your child's learning — it knows them inside out.
How Cognaa fits your family or school.
What grades is Cognaa for?
Cognaa serves K–12 learners. Our deepest mastery coverage is currently K–8 Math, with ELA, Science, and Writing expanding across Common Core, TEKS, state-specific, and CBSE frameworks.
Is my child's data private?
Yes. Parent-controlled accounts, age-appropriate safeguards, minimal collection. Export or delete anytime. Your child's conversations are never used to train general-purpose AI models.
Does Cognaa replace a curriculum?
It's flexible. Run Cognaa as a complete adaptive curriculum, or as a tutor alongside what you're already using. Either way, it adapts to your child and keeps you in the loop with personalized explanations, practice, and clear progress signals.
Can I build my own AI skills?
Yes — the Skill Builder lets any parent or educator describe a learning objective and Cognaa generates a ready-to-use skill (with the right tools, prompts, and KC mappings). No prompt engineering required.
