Our verdict
Kling AI suits video makers who want to try fast-moving models and need text-to-video or image-to-video with many controls. The trade-offs are credit costs that add up, unclear commercial-use terms and very low Trustpilot scores on billing and support.
Best for: Creators who need short clips from text or images and want a current-generation model such as Kling 4.0
Skip it if: Anyone who needs commercial rights spelled out per plan in the published terms
Pros
- Kling 4.0 pairs video with synchronized audio; the app listing mentions output up to 4K
- Web, iPhone and Android apps and an API, plus Canvas and agent tools
- Strong app ratings: 4.7/5 on the App Store (about 34K) and 4.5/5 on Google Play (about 634K)
Cons
- Trustpilot scores it 1.2/5 from 441 reviews, 91% one-star, mostly about renewals, cancellation and support
- Trustpilot reviewers say failed generations still consume credits

Problems it solves
Experience & key features
Kling AI is an AI video and image generator developed by Kuaishou. Per Wikipedia, the first version launched in June 2024 as a public test inside the KuaiYing video editing app. The homepage now presents Creative Studio, Canvas (an agent-assisted workspace), an API platform and the Kling 4.0 model.
Per Wikipedia, Kling 4.0 launched globally in October 2026, adding native 30-second video, 4K 10-bit HDR, stereo audio and expanded keyframe editing. The App Store listing mentions clips up to 15 seconds at 1080p or 4K, extension to 3 minutes and native 4K images.
Pricing and credits
The US App Store lists Standard at $10, Pro at $37 and Premier at $92 per month, plus one-off credit packs from $5 to $100. Per a third-party summary by eesel AI, the plans carry 660, 3,000 and 8,000 credits a month, annual billing saves about 34%, and subscription credits do not roll over. On the API side, the official pricing page sells prepaid packages, for example $500 for 3,250 units valid for 180 days; Kling 4.0 costs 1.0 unit per second at 720p and 1.5 at 1080p with no input video.
Terms and reception
The terms of use bar commercial use of output without Kling AI's written permission and require Kling AI labeling, while per-plan rules sit in separate documents this review could not check. Trustpilot scores it 1.2/5, with complaints about auto-renewal, cancellation and credits deducted for failed runs, though the profile is unclaimed and may not be representative. Wikipedia also notes censorship of sensitive political topics.

Versus alternatives
Kling AI competes directly with Runway, Hailuo AI, Luma Dream Machine, Sora and Google Flow. Before choosing, compare cost per second of video, commercial rights and how each service treats credits on failed generations. To try it cheaply, the App Store lists a one-week Standard membership ($1.19–$1.49) for judging quality before a longer commitment.

Cancellation & refunds
The official terms of use (updated April 21, 2026) say only that if Kling AI discontinues its services it will refund prepaid, unused services. Subscription refund rules sit in a separate Terms of Paid Service and Credits Policy, separate documents this review could not check.
Privacy
The privacy policy (updated April 21, 2026) says Kling collects account details, uploaded user content, payment information and usage data, and that content may be scanned for safety review. Data is stored on servers in Singapore. The minimum age is 13 in most regions; in Vietnam users must be 16 or have parental permission. The terms of use let Kling AI use inputs and outputs to train or develop its AI models; you can revoke the authorization by email, but the terms do not say what revocation covers. The terms also restrict commercial use of output without Kling AI's written permission.

Why this score
Standard is $10, but credits do not roll over and users report that failed runs still cost credits. Much plan detail is only available from a third party.
Why this score
The homepage touts stable motion and an immersive audio-visual experience in Kling 4.0 (vendor claims). Trustpilot reviewers complain of inconsistent characters and ignored prompts.
