Slatecraft

AI video

Slatecraft is an independent AI video generation website based on the Vidu Q4 Preview model, primarily offering two methods: Image to Video and Reference to Video. Users can upload an image as the first frame, or up to 12 reference images along with up to 3 MP3 audio clips to build multi-character scenes and dialogue. Generated videos are 3–16 seconds long, with output up to 4K, and come with synchronized dialogue and sound effects. Videos are billed by the second, with credits purchased through a $2.99 one-time trial pack or subscription plans starting at $9.90 per month; the button displays the exact cost before rendering, and failed generations automatically refund credits. Slatecraft is not affiliated with Vidu or ShengShu Technology, and the official statement says it does not support text-to-video, nor does it have timeline editing features.

Sleep Calculator

Other AI tools

Sleep Calculator is an online sleep time calculation tool based on the 90-minute sleep cycle that helps users calculate recommended times to fall asleep or wake up according to a desired wake-up time or bedtime. The website provides a simple interface: enter the time you want to wake up or the time you want to go to sleep, and the calculator will give multiple time suggestions based on complete sleep cycles (each cycle is about 90 minutes). Users can choose the time that suits their own schedule to reduce the grogginess caused by being awakened during deep sleep. The material also mentions that a sleep cycle includes light sleep, deep sleep, and REM sleep; a complete cycle helps avoid discomfort when waking up; REM sleep is crucial for memory and emotional regulation; and each night should include 5–6 complete cycles. The page also includes user reviews and frequently asked questions, but it does not explain additional features, pricing models, or specific algorithm details.
