EverGen AI is an AI video generator for short-form video, turning a prompt or a product photo into a vertical Short, a video ad, or a UGC-style clip with sound. You describe the hook, the action, and the camera move, or upload a product photo as the first frame, then pick from 14 video models including Seedance 2.5, Veo 3.1, Kling v3, Sora 2, Wan 3.0, and MiniMax H3, with aspect ratios from 9:16 to 16:9, durations up to 30 seconds in a single take, and resolutions up to 4K. Models with native audio generate dialogue, sound effects, and room tone in one pass, so a UGC-style ad reads like a creator talking to camera. Reference-to-video mode keeps the same character across clips by assigning each reference image a job: face, outfit, or place. You can write a prompt and pick a model before creating an account, and the exact credit cost shows on the generate button before anything runs. Plans start at $14.90 a month for 1,000 credits, one-time credit packs are also available, failed generations refund automatically, and downloads carry a watermark until the first purchase. It suits creators and marketers who want testable short video ads the same day they brief them.
