THE SHORT ANSWER
What it actually is
Vidu AI is a generative video service that turns text prompts, still images, and reference material into short motion clips. It belongs to the same broad category as other AI video generators: you describe a scene, the system predicts visual frames, and you refine the output through additional attempts.
That makes Vidu AI legitimate as a real creative technology, not a magic shortcut or a guaranteed substitute for an editor. The platform can be useful for storyboards, social concepts, mood pieces, product ideas, and visual experiments. It is less dependable when a project requires exact typography, long uninterrupted action, precise identity matching, or frame-perfect brand control.
