Can I use it for free?

New accounts are granted free credits — up to 120 with a Google account, depending on your country — enough to try video and image drafts. After that, top up with a subscription or a credit pack.

Does it work on mobile?

Kling AI is browser-based, so it runs from a phone or tablet browser as well. No app install.

Can I use the output commercially?

Within applicable law and each model's usage terms, you keep the rights you hold in your output. See the terms of service for details.

How long does generation take?

It depends on model, resolution and length. Fast models like Kling 3.0 Turbo return quickly; 4K and longer clips take more time. Kling AI shows generation status on screen.

How do I keep Kling AI credit use down?

Resolution, duration and model are what move consumption. Settle the framing on Kling O3 at 720p and short lengths (about 75 credits for 5s), then rebuild only the chosen cut at 1080p or 4K on Kling 3.0. Kling 3.0 Turbo is fast but costs more per run (about 128), so it is not the model to pick for savings. The estimate is always shown before you run.

Where are generated videos saved?

Finished videos can be previewed in the browser and downloaded from there. What you may do with a downloaded video is governed by each model's terms and applicable law.

When something isn't working, where do I start?

Check prompt specificity, then whether a reference image would help, then the model choice. If the subject drifts, add a reference image; if the movement is wrong, consider motion control. Change one thing at a time to isolate the cause.

How to use Kling AI

What trips people up on their first Kling AI session is rarely the generation itself — it is choosing a model and knowing where the credits go. Here is account creation through downloading your first video in five steps, with what to decide at each one and where the cost changes.

Generate a video with Kling AI in five steps

1
Create an account and claim free credits
Create an account with email or a social login and you are granted free credits — up to 120 with a Google account, depending on your country. No payment details are needed at this point; you can try video from prompts or images inside that allowance.
2
Pick the model that fits your goal
Kling 3.0 for finish quality, Kling O3 for cost, Kling 3.0 Turbo for speed, motion control for transferring movement, Kling O3 Image for stills. If you are stuck, choose from what you have: text only, a reference image, or a reference video as well — that alone halves the candidates.
3
Write a prompt or upload a reference image
Describe the scene in the order subject, movement, camera, mood. "A brown tabby stretching by a window at dusk, slow motion" is far steadier than "a cat". Upload a reference image to pin the subject or style; start and end frames can also be specified.
4
Set resolution, length and audio, then check credits
Choose 720p / 1080p / 4K, the clip length, and whether to include audio. All three feed straight into credit consumption, so running the first few attempts at 720p and short lengths buys you more tries. The credit estimate appears just before the generate button.
5
Generate and download
When the generation finishes, preview and download it. Credits are deducted only on success — a job that fails on a system error costs nothing. If the result is off, change one thing in the prompt and rerun; that makes it clear which change did the work.

Prompt habits that make Kling AI results steadier

Be specific

Write subject, action, light and camera concretely: not "a cat" but "a brown tabby stretching by a window at dusk, slow motion". This is not specific to Kling AI — the vaguer the wording, the wider the model's room to interpret, and the more results scatter.

Test cheap first

Confirm framing and movement on Kling O3 at 720p, then finish on Kling 3.0 at 1080p or 4K. Starting at 4K is a cost you can safely defer until the direction is fixed.

Lock it with a reference image

To hold a character or style steady, pass a reference image rather than relying on text. For anything where a changed appearance is a problem — people, products — one reference image is almost always faster than more prompt engineering.

Japanese or English

Prompts can be written in Japanese, though English is sometimes closer to intent. Adding the English term alongside specific motion or style words helps. The Kling AI prompt box accepts either language.

Change one thing at a time

Rewriting the whole prompt when something is off hides which part mattered. Change only the camera, or only the lighting, and you converge in fewer runs.
