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.

Generate reading passages and questions on any topic in seconds, or choose from thousands of standards-aligned fiction and nonfiction texts written by real authors.
One dashboard shows growth, mastery, and gaps across every student, class, school, and district, reporting in Lexile, grade, and ELA standard terms.
Passages, quizzes, graphic organizers, and worksheets are available to print for small groups, substitute days, and screen-free lessons.
