Web AI video generator: text, image & audio to video
What is Kling 4.0 AI?
Kling 4.0 AI is an AI video generator.
Kling 4.0 AI (kling4pro.com) is a web-based AI video generator that turns text prompts, still images and audio into short, high-quality video clips directly in the browser, with nothing to install. It is an independent third-party service and is not the official Kuaishou or Kling product. The core workflows are text-to-video, image-to-video (up to nine reference images, first and last frame control), and audio-driven lip sync. Clips run up to about 30 seconds in 16:9, 9:16 or 1:1, with 4K watermark-free MP4 export. The workspace also includes video editing, a prompt agent, and other models (Kling 2.x/3.0, Veo 3.1, Seedance, Hailuo). New accounts get free credits; paid plans start at $16/month.

I wrote a SQL query that literally put together this list based on the data that my product had. I posted a link to this sheet in this post and when a member of the group opened this sheet they would be met with this list — but then what they also saw was the link to my website where all of the data was actually coming from. I had over 1,500 people visit the website just from posting this spreadsheet.
A free spreadsheet with embedded link drove 1,500 site visits from one post
Instead of pitching his product directly, Anish generated genuine value for a Facebook group by querying his own database and sharing the results as a free spreadsheet. The product link was visible inside the sheet, turning a helpful post into a high-converting acquisition channel.
The numbers you see first when you read through Apple's documentation are 10% and 17% that basically replace the 15 and 30% typical Apple cut. However Apple now charges 3% — that means you end up at 13% and 20% if you're using IAP.
New 17%/10% commission balloons to 20%/13% once you add Apple's 3% payment fee
The headline 17%/10% rates only apply if you bring your own payment processor. Stay on Apple's billing and you pay 3% on top, landing at 20%/13% — far less attractive than the marketing suggests. The cut is closer to a few points of relief than half-off.
There's a play for whatever you're stuck on.
