An infinite AI canvas that turns scattered ideas into finished plans
Notes, images, videos, links, colours, audio memos with transcription, and freehand drawing all live on one pan-and-zoom board.
The agent reads the whole board, not just the current note, so it can summarise a project, answer questions about it and write structured cards into your layout.
Jump straight into a video brief, app flow, website plan, storyboard, roadmap, moodboard, competitor research or weekly planner.
Embed lightweight interactive elements such as skill meters, status views and to-dos directly inside the canvas.
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.
