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.
Enterprise developer platform and API for deploying GPT-6 Astra, Sol, Luna, and realtime multimodal agents.
Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.
Provides direct API access to Google's Gemini models with generous free prototyping tiers, but lacks OpenAI's ecosystem breadth.
