Submit is a collaborative visual canvas for creating AI agent workflows. Drag and drop 20+ nodes onto a graph: LLM agents, routers, HTTP calls, web search, deep research, MCP servers, image/video/audio/3D generation, transcription (with PII masking), email, tables, HTML and presentations. Every graph runs on a durable engine with retries, on-demand, on a schedule or triggered by webhook. Add a human-in-the-loop approval gate, collaborate in real time, and publish your flows to the gallery.
