ComfyUI-Copilot

ComfyUI-Copilot is an AI assistant built into ComfyUI from Alibaba International Digital Commerce. It supports building workflows, answering ComfyUI questions, optimising parameters and iterating. Version 2.0, announced in August 2025, is described as moving from a helper tool to a development partner that can complete workflow tasks itself, covering generation, debugging, rewriting and parameter tuning, and being aware of your local ComfyUI environment.

The README lists core features: generating a first workflow from a text description (three workflows from a library plus one AI-generated), one-click debugging that analyses errors, fixes parameter and connection problems and prompts you to download missing models, rewriting a workflow from a description, a GenLab tab for batch parameter tuning with visual comparison, node recommendations, a node query system and model recommendations for base models and LoRAs. It gives practical cautions: models released after May 2025 (such as Wan 2.2) may confuse the LLM, rewrites carry a lot of context so you should clear context often, and parameter tuning needs a workflow that already runs.
