Fill in your character’s traits once. Get a reusable character-lock sentence to paste at the top of every shot prompt — same face, outfit and personality across the whole video.
🔒 Everything runs on your device — your video, images and ideas never leave it. The model downloads once, then works offline.
Your ideas and prompts never leave your device. No uploads, no logs, no one watching. True for every single generation.
The model runs on YOUR hardware, so there's no server bill for anyone. No API keys, no quotas, no paywalls — generate 100 prompts a day.
After the one-time download, the model lives in your browser cache. Turn off Wi-Fi and it still generates — airplane mode, no problem.
No account, no email, no analytics on your prompts. The model has no idea who you are — and neither does anyone else.
Hand your ideas to a cloud tool and they live on a server you can't see. A local model keeps every choice — and every word — with you.

Copy the card and paste it at the top of every shot prompt. For even stronger consistency, generate a reference image from the card and upload it in Kling or Dreamina’s reference-image feature — then keep repeating the card in every shot.
The 8 short drama templates come with ready-made characters like Lin Feng or Su Wan. The generator builds a card for YOUR character — any name, appearance and genre — in the same lock format.
Completely free, no sign-up. The AI model runs 100% in your browser via WebGPU — your character settings never leave your device.
