Cartoon and sketch

Cartoonization, pencil-sketch generation, and three preset anime styles. The preset names are not repeated on the website.

Name the job, then open that tool

A vertical reframe is smart crop. A pencil look is sketch. A new light on a face is relight. They do not share one slider.

Frequently Asked Questions

Is my footage uploaded to the cloud?

No. The AI processing runs on your own GPU and your media files are not uploaded — there is no queue and no per-minute cloud fee. The network is used only for sign-in and license checks (needed to export on a paid plan) and for updates.

Can I try it before buying?

Yes. Download KwaFlux and render 1-, 3-, and 5-second effect previews across all AI modules without creating an account. You only sign in and pick a paid plan when you want to export or convert, and there is a $199.99 Perpetual License if you prefer to skip subscriptions.

How many devices can I use?

Each license can be used on up to 2 devices. Sign in on a new device to activate it; if you are already at the limit, the least recently used device may be signed out automatically. You can also revoke devices from your dashboard at any time.

What are the pricing options?

The Perpetual License is $199.99 one-time. Subscriptions are also available at $29.99/month, $49.99/quarter, and $79.99/year. All plans include the full local desktop feature set.
