Master any codebase, instantly.
Deck optimizes for reading comprehension and knowledge acquisition in a world of code abundance. Reduce mentorship debt and build deep mental models while AI handles the velocity.






Combat Cognitive Overload and Mentorship Saturation.
Shift from velocity to comprehension with an Intelligent Tutoring System embedded in your workflow. Build mental models while AI generates solutions.
Active Knowledge Tracking
Build a probabilistic model of what you know using Bayesian Knowledge Tracing. Visualize coverage with a Knowledge Heatmap.






User-State-Aware RAG
Personalized explanations that bridge the gap between code and your specific knowledge state, targeting the Zone of Proximal Development.






GraphRAG Structural Context
Understand downstream implications and system patterns with local-first dependency analysis. Never be blind to architectural impact.






Accelerating the next generation of builders.
Deck is the trusted cognitive partner for teams shifting from simple code generation to deep system comprehension.
Scaling the zone of proximal development for every engineer on the team.
Focused on high-growth engineering organizations.
Reducing the $200k economic burden of high-velocity onboarding.
Investment in developer experience and productivity.
Eliminating the 'Bus Factor' risk with team-wide knowledge mapping.
Protecting critical system knowledge and architecture.
Ever since we started using Deck, our junior engineers have stopped just prompting solutions and started actually building mental models. The ramp-up time has dropped by 20%.
