Node-based visual AI studio for images, video, 3D and audio
Connect models, samplers, conditioning, LoRAs and output nodes on an infinite canvas where every step is visible and adjustable.
One interface for image generation, video, 3D assets and audio or music workflows, with support for leading open and partner models.
Run ComfyUI locally on your own GPU, or open the same workflows in the cloud when you don't have the hardware.
Deploy any workflow as a production API so your own app or agent can generate outputs on demand.
AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
