One AI workspace that answers from your own notes, documents and research
Chat with top-tier models from OpenAI, Anthropic and Google, and switch between them mid-conversation without losing context or opening a separate app.
Connected Chat quotes your notes, documents and saved pages, and each claim carries a tappable citation back to the original source.
Clip links, PDFs, screenshots and emails into an Inbox, then organize sources into Collections and ask questions across an entire project.
Turn YouTube videos, lectures, podcasts, webpages and PDFs into transcripts, summaries, flashcards, quizzes and concept maps.
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.
