Bonega turns a prompt or an image into a video of any length, extended take by take without a total cap.
Bonega is built for length: every extension continues the clip before it, so the story sets how long a video runs, not the model.
We built Bonega around a single pipeline that routes each request to the model we currently rate highest for the task, so you never have to pick or compare anything.
One pipeline, re-routed as better AI tools ship. The price per second depends on the resolution you choose, not on the model.
Generate videos of any duration
Standard is 720p, and 2K (2560 x 1440) is available at a higher credit price, with an optional 4x upscale
Bonega AI is a video generation platform that turns a text prompt or an image into video, and extends a clip by chaining successive generations. It was previously called Lengthen, and the two names refer to the same product and the same accounts.
One pipeline, not a menu. We route each request to whichever model we currently rate highest for that job and change the routing as better models ship, so you do not choose or compare models and the price does not change when the routing does.
Choose a plan on the pricing page, then describe the video you want or upload an image to animate. Each generation and each extension consumes plan credits; current prices and credit amounts are on the pricing page.
Bonega is operated by Clashware, a Swiss company based in Lausanne. The same team builds the iOS apps listed on our apps page; about half of them call this backend, and the rest do their work entirely on the device.
The benefit is that you never pick a model and never pay more when we upgrade one. The drawback is the other side of the same decision: you cannot pin a specific model or reproduce an old render exactly once we have moved on from the model that made it.
If you want video out of a prompt without researching which model is best this month, Bonega is built precisely for that and the routing is the product. If you need a named model, a fixed seed, or byte-identical reruns months later for a client deliverable, use a tool that exposes the model directly, because we will keep changing ours when something better ships.
