If your goal is to generate structured specs from ideas/code/designs, Userdoc is the clear pick with its agentic code-to-docs and image-to-specs. If your priority is keeping AI coding assistants hallucination-free with always-fresh docs for exact library versions, Context7 wins. They solve different problems so choose based on whether you need to author requirements or consume correct docs.
