Seadanse

Seadanse is a browser-based generative media studio that centers on the Seedance 2.5 video model. You can start from a written prompt, a set of reference photos, an existing clip, or a piece of music, and the platform renders a scene of up to about 30 seconds where picture and audio are generated together rather than assembled in post. An AI Video Agent layer sits on top of the raw model: describe a video in one or two sentences, let the built-in rewrite tool sharpen the prompt, and the agent returns a finished spot suitable for brand promotion or advertising.

Beyond straight generation, Seadanse leans heavily on templates. Its library collects trending social-video formats — pet dances, prank clips, music-video dance scenes, meme recreations — each with preset camera work, sound and duration, so you only supply a photo or two. Image generation is handled by separate models such as GPT Image 2.5, Nano Banana 2, Seedream 5 Lite and Grok Imagine Image, with utilities like a background remover and sprite-sheet generator for game and asset work. Model choice spans Seedance 2.5 and 2.0, Hailuo 3, Kling O3 and Veo 3.1, so you can trade quality against cost per render.

Seadanse is an independent site and is not affiliated with ByteDance or the official Seedance team; it is one of several third-party front-ends that expose these models. Access is credit-based with 40 free starter credits on sign-up, and pricing includes per-video template purchases, credit packs and subscription tiers. Because specific rates and available models change frequently, check the pricing page for current numbers before committing budget.
