Turn a plain-language idea into a real, live web app — no code required
Type a short description of your idea and Capacity asks a few questions, then builds the pages, data and logins in minutes with a live preview.
Generated apps can include member accounts, logins, saved data and payments, not just static mockups.
Connect Capacity to Claude or ChatGPT and build from the chat; each message runs on your AI plan rather than Capacity credits.
One click publishes the app to the internet, and you can attach a custom domain name in minutes.
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.
