About Kling 4.0
kling4.co is an independent platform for generating video and images with the Kling family of AI models. You give it a text prompt or an image, and it returns a finished clip or picture in the browser. It runs 14 video models and 2 image models behind one account and one shared credit balance, and it shows the credit cost of a request before the request runs. This page is the authoritative record of what the site is, what it supports and what it charges; the model list, the free allowance and the prices below are generated from the site's live configuration rather than typed in, so they cannot fall behind the product.
Who operates kling4.co
kling4.co is operated by an independent team. It is an unofficial third-party service: it is not affiliated with, endorsed by or operated by Kuaishou, the company that develops the Kling models, and it is not the official Kling AI product. Product, billing and privacy questions go to support@kling4.co, which is monitored by a human on business days.

How credits work
The site uses a single credit balance that works across every video and image model — there is no separate video wallet and image wallet. The credit cost of a request is displayed before you run it, so a generation never costs more than the number you saw, and a generation that fails is refunded automatically. Credits bought in a pack do not expire.
The free tier
- 100 credits are granted when you create an account — no card, no subscription. They do not expire.
Plans and prices
Subscriptions grant credits on a recurring basis; credit packs are one-time top-ups that can be bought at any time and stack on top of a plan. Current promotions and checkout are on the pricing page.

Content and usage rules
Generations made on kling4.co may be used commercially, subject to the terms of service, and downloads carry no watermark on any plan. Prompts and outputs pass through automated safety filters and provider-side moderation; content that breaks the acceptable-use rules can be blocked before it runs or removed afterwards. Reports go to support@kling4.co with the subject line "Report". How personal data is handled is documented on the privacy policy page.
Frequently asked questions
What is kling4.co?
kling4.co is an independent platform that runs Kling AI video and image models in the browser. You give it a text prompt or an image, pick a model, and it returns a video or an image. Everything runs server-side; there is nothing to install and no local GPU is involved.
Is kling4.co the official Kling AI site?
No. kling4.co is an independent third-party platform. The Kling models are developed by Kuaishou, and this site is not affiliated with, endorsed by or operated by Kuaishou. What the site provides is access to those models under one account and one credit balance.
Is kling4.co safe to use?
Payments are handled by the payment provider and card details never reach this site. Generations are private to your account. Account and data handling are documented on the privacy policy page, and the acceptable-use rules are in the terms of service.
Do I need a credit card to try it?
No. Creating an account grants a starting credit balance with no card and no subscription, and that balance is enough to run a generation on the entry-tier model. Paying is a separate, later decision.
Are the videos watermarked?
No. Downloads are watermark-free on every plan, including generations paid for with the free signup credits.
What happens if a generation fails?
Credits for a failed generation are returned automatically. The credit cost is also shown before a generation runs, so a request never costs more than the number you saw.
Can I use the output commercially?
Yes, subject to the terms of service. Output is watermark-free on every plan, which is usually the practical blocker elsewhere.
