About Scene Assembly
Scene Assembly is a studio for generating and editing images and for creating video — built around choosing the engine that fits the work, not locking you to one vendor. Use Google Gemini when you need grounded, multi-reference editing; Veo, Kling, or Seedance when the job is video. No monthly subscription: connect the provider keys you already use and pay as you go. The studio is the interface on top.
There is no Scene Assembly subscription and no credit to buy. You paste a provider key — Gemini, fal.ai, Kie.ai, Runware, Atlas Cloud, CometAPI, PiAPI or a Cloudflare token — and generations bill to that provider account at its own rates.
As a guest, credentials live in this browser’s local storage and are sent only with your own generations. Sign in with the optional account and saved connections are encrypted instead, so background jobs can keep running after you close the tab.
Pollinations runs FLUX text-to-image with no credentials at all, and Cloudflare Workers AI has a free daily tier. Both are enough to try every part of the interface before you connect anything paid.
Every engine below is selectable per generation, so the same prompt and the same reference images can be re-run somewhere else without leaving the page.

Six image modes, three ways into video, and a timeline to cut the results together:
A clip can start from a prompt, from a still you just generated, or from a first and last frame you hand it. Finished clips land in a rail you can drag onto the timeline, trim, reorder, and export as a single file — without uploading anything to us.
