Time blocking for macOS that plans around your calendar
Drag tasks from your list onto the timeline or apply recurring templates to fill your day with focused blocks.
Events sync both ways with Apple, Google and Outlook calendars so your plan and your real calendar stay aligned.
Work the same plan as a day timeline, a week grid or a month view, and export to PDF or CSV when you need a copy.
Treat lists as projects with an overview, deadline and finish line, and split large tasks into scheduled sessions.
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.
