What Kling AI is
Kling AI is a video generator made by Kuaishou, a Beijing-based technology company that also runs a popular short video platform. You describe a scene in words, and Kling draws it as moving video. It first opened for public testing in June 2024, inside Kuaishou's KuaiYing editing app.
It runs in a web browser on kling.ai, the international site, while klingai.com serves China. The newest model, Kling 4.0, was announced as fully available on kling.ai on 15 October 2026. Use is freemium: Kling's payment policy says non-members keep its brand and logo on what they make, and paid memberships add things such as watermark removal and video extension.
What Kling AI is good for
- Clips from a text prompt: a paper boat in a rain gutter, a product turning on a table. Kling calls this Text to Video.
- A photo that moves: upload a start picture and describe only the motion. Kling calls this Image to Video.
- Longer single shots: Kling's launch video lists native 30-second generation for version 4.0, and a tutorial on version 3.0 covers clips up to 15 seconds.
- A short story across keyframes: give a start, a middle and an end picture. Kling 4.0 takes up to 10 keyframes, its launch video says.
- The same character or product in every shot: Elements in version 3.0, and Omni Reference in 4.0, which takes up to 15 references.
- Talking characters: the tutorials show an AI avatar tool and a lip-sync tool that matches a mouth to speech.
When to use Kling AI, and when to pick another tool
| Your job | Use Kling? | Or try |
|---|---|---|
| A short clip for a social post or an ad | Yes. Members' commercial use is not restricted, in Kling's words | Gemini's video tools, which need a Google AI plan |
| A free first try at AI video | Possible, but non-members keep Kling's brand and logo on the clip | Runway or Adobe Firefly, which list free allowances |
| A clip with sound or speech | Yes. Kling 4.0 lists stereo audio and lip sync | ElevenLabs, if you only need the voice |
| A still picture with words in it | Not the best fit | Ideogram |
| A clip on a politically sensitive topic | Often no. Wikipedia, citing a 2024 TechCrunch report, says Kling refuses such prompts | An open model such as Wan in ComfyUI on your own computer |
| A song or background music | No | Suno |
How to use Kling AI, step by step
These steps are for Kling's website. Menus move when the app updates, so they stick to the parts that stay put: signing in, the two ways to start and the main buttons.
- Open kling.ai yourself by typing it in the address bar, then sign up. Fake Kling sites and ads spread malware in 2025, so skip any link in an ad.
- After you sign in, open the video tool and choose Text to Video to start from words, or Image to Video to start from a picture.
- For Image to Video, upload your start picture. A clear photo or illustration with one main subject gives the clip something firm to move.
- Type your prompt: the subject, what it does, how the camera moves and the light. Keep to one move per clip.
- Choose the model version, the clip length and the shape (wide, square or tall). Kling spends credits on each clip, so check the credit cost near the button before you press it.
- Press Generate and wait for the clip to render.
- Watch the whole clip with the sound on. If one thing is off, change only that part of the prompt and generate again.
- Download the clip. Free use keeps Kling's brand and logo on it, and removing them is a member feature.
After you sign in, open the video tool and choose Text to Video to start from words, or Image to Video to start from a picture.
Type your prompt in the box: the subject, what it does, how the camera moves and the light. Keep to one move per clip.
Choose the model, the clip length and the shape in the row under the prompt.
Check the credit cost on the Generate button, then press it and wait for the clip to render.
AI-made illustrations of Kling's screens, drawn on 6 November 2026 to match these steps. They are not screenshots, so the real app may look different: follow what you see.
The tutorials at the top of this page show these steps on screen. Kling changes its menus now and then, so if a name differs, follow the one you see.
An example to try
Paste this prompt after choosing Text to Video. It names one subject, one camera move, the light and the sound, and no more.
A paper boat drifts down a rain gutter after a storm, seen from just
above the water. The camera follows the boat slowly from behind. Late
afternoon light, puddles reflecting a gray sky, small ripples around the
boat. Sound: rain dripping and a faint splash. No people, no text.- The boat stays in frame from start to end, and the water ripples around it.
- The camera trails the boat from behind at a steady pace.
- The light looks like late afternoon, with a gray sky in the puddles.
- No people and no text appear. If your model makes sound, you hear drips and a faint splash.
- If the boat drifts out of frame, change only the camera line and run it again.
Tips for better results
- Name the camera move in plain words: a slow push in, a pan, a follow shot or a still hold.
- Describe the sound if your model makes it. Kling's launch video lists stereo audio and more accurate lip sync for version 4.0.
- Give each reference picture a job in the prompt: which one is the face, which is the outfit, which is the place.
- Try a short clip before a long one. Shorter clips use fewer credits on most platforms, so a bad prompt costs less.
- Move to Multi-Shot only after a single shot works. The Kling 3.0 tutorial separates Single Shot, Multi-Shot and Custom Multi-Shot.
What to know before you pay
- Free clips keep Kling's brand and logo. Kling's payment policy says non-members must leave them on, and that watermark removal and video extension are for members only.
- Kling's payment policy says members' commercial use is not restricted. Read the policy yourself before a clip goes into an ad.
- Kling spends credits on each clip. Its credits policy sets how they work, so read it before you buy a membership.
- Kling blocks some topics. Wikipedia, citing a 2024 TechCrunch report, says it refuses prompts on sensitive subjects such as politics, protests or criticism of the government.
- API access for enterprise customers and developers was listed as coming soon in Kling's 15 October 2026 post. Check whether it has arrived before you plan an app on it.
- A photo of a real person needs that person's consent.

Frequently asked questions
Is Kling AI free?
Partly. Kling's payment policy says non-members must keep Kling's brand and logo on what they make, which means clips exist without a membership, and members get watermark removal and video extension. The policy pages read for this site state no free allowance, so check the sign-up screen for the current one.
Who makes Kling AI?

Can I use Kling videos in ads?
