Why people switch from Grok Imagine to Yerk.app
Some people want a different way to pay. Others want an app made only for pictures and video, or help turning an idea into a prompt that works. Yerk.app is built for all three.
Credits, not a weekly pool
Buy credit packs when you need them. There is no subscription, paid credits do not reset monthly, and the app shows the cost before you create.
One app for pictures and video
and share one account and one credit balance, so the frame and the clip stay together. Edit Any Video changes an existing video up to 30 seconds from a written instruction.

How to move a Grok Imagine workflow to Yerk.app
The easiest switch is not to copy a brand name or chase a one-for-one model label. Copy the creative job: make a good starting frame, describe the motion, check the cost, and iterate.
- Open Yerk.app in a browser. Sign in to create a Yerk account. Yerk.app is free to start, and eligible new accounts can get free starting credits.
- Build the still in . Type the idea, or upload an image, and describe the finished picture you want. makes pictures up to 4K.
- Turn the still into a clip in . Use image-to-video when the starting composition matters, or describe a scene directly for text-to-video. 's public tray currently includes Yerk, Professional (Seedance 2.0, Seedance 2.5, Horse, or Edit Any Video), and VIP. Ask Yerk AI if you are unsure which one fits.
- Make intent explicit. When High Fidelity is available, use it when you want help keeping the prompt's structure and intent. For motion, name who or what moves, the order of actions, camera direction, and the ending state.
- Check the run before you spend. Confirm the model, length, aspect ratio, sound and the credit cost shown before you create. A quick draft is a good first pass.

A founder note: why I built Yerk.app
I built Yerk after spending thousands of dollars in credits testing image and video services, prompts, and handoffs. I was making original videos for YouTube, and the frustrating part was not that a service had boundaries. It was losing time to a workflow that did not make the result or the next step clear.
So I built the visual app I wanted: creates the frame, carries it into motion, the model choices stay visible, and credits are used when you create instead of being tied to a monthly seat. The prompt-fidelity approach matters to me because creators should be able to tell what they asked for, what the tool changed, and what they are paying to try.
