The teaching layer that explains every line your AI coding agent writes
Every line your agent writes is explained as it happens, covering what the code does, why it was written that way and the intended goal, in the same window.
A VS Code extension brings the teaching layer to Cursor, Copilot, Claude Code, Codex CLI, Cline, Kilo Code, Windsurf, Antigravity and more without changing your agent.
Plan, Fast, Deep and Recursive modes let you propose before writing, iterate quickly, reason deeply, or let the recursive agent plan multi-step work.
49+ prerequisite-locked topics, projects, graded checkpoints and boss exams inside the IDE, with a hint economy earned by completing topics.
High-efficiency open-weight and hosted reasoning AI powered by DeepSeek-V4 and R1 at ultra-low token costs.
Leverages a sparse Mixture-of-Experts architecture (49B active parameters out of 1.6T on V4-Pro) to process up to 1 million tokens with minimal latency and memory overhead.
Pioneered by DeepSeek-R1 and integrated into V3.2 and V4 thinking modes, exposing step-by-step self-verification for complex math, logic, and code debugging.
Drops input token costs to $0.003/1M on Flash and $0.022/1M on V4-Pro for cache hits, with 50% lower rates during off-peak UTC hours.
Provides free access at chat.deepseek.com and on iOS/Android with document uploads, reasoning mode, and web search without paywalling core models.
Provides stronger multi-modal reasoning and agentic tools, but lacks DeepSeek's ultra-low-cost API pricing.
