How to use Grok AI for free to turn images into videos

Grok AI is back and, yes, you can use it for free again. Instead of paying for a premium subscription, you can access the Grok video model through a credits-based platform that lets you turn still images into short AI-generated videos. If you create content, experiment with AI, or just want to bring your images to life, this is a simple way to get started without paying upfront.

How the free Grok AI access works

The trick to using Grok AI for free is a third-party platform that hosts multiple AI models for images and video. When you sign up, you receive a daily allowance of credits (for example, 150 credits per day). Each time you generate a video with a model like Grok, the platform deducts a certain number of credits.

Grok is one of several available video models. Others include options like "Students 2.2" or "V03," each with different credit costs. Grok typically sits in the mid-range: more expensive than some basic models, but cheaper than the most advanced ones. Because credits refresh daily, you can keep using Grok over time without paying, as long as you stay within your daily limit.

Signing up and logging in

To get started, go to the platform’s website and create an account. You can usually sign in with Google, Microsoft, or other common login options. Once you’re logged in, you’ll land on a dashboard where you can create a new project or file.

From there, choose to create a new file or workspace. This opens the main interface where you’ll connect different elements: your video model (Grok), your prompt, your input image, and your export node.

Setting up your Grok video workspace

Inside the workspace, you’ll see a panel with different types of elements and models. Look for the section that contains video models. This is where Grok lives, alongside other options.

If you don’t see Grok immediately, use the search bar to find it by name. Once you see the Grok block or node, drag and drop it into your main canvas. Simply clicking it won’t be enough—you need it placed in the workspace to connect it to other components.

Adding your prompt, image, and export nodes

To actually generate a video, Grok needs three things: a text prompt, an input image, and a way to export the result.

Right-click in the workspace and add a Prompt node. This is where you’ll describe what you want Grok to do with your image—movement, style, mood, and any specific actions. Even a simple prompt can work if you just want to test how Grok animates your image.

Right-click again and add an Input node. This is used to bring in your source image—the picture you want to animate. You can upload an image you created earlier with another AI tool or any other visual you want to turn into a short video.

Finally, add an Export node. This tells the system to render and package the final video so you can download it.

Connecting everything together

Once all the nodes are on the canvas—Grok, Prompt, Input, and Export—you need to link them. If you don’t connect them, nothing will run.

Drag from the Prompt node to the Grok node to connect your text instructions. Then connect your Input node (the image) to Grok as well. After that, connect Grok to the Export node. The flow should look like this: Input + Prompt → Grok → Export.

These connections tell the platform: use this image and this prompt with the Grok model, then send the result to export as a video file.

Choosing duration, resolution, and outputs

Click on the Grok node to open its settings. Here you can control how your video is generated:

Duration: Set how long you want the video to be, for example 10 seconds. Longer videos consume more credits, so if you’re trying to stretch your daily allowance, keep durations short while you experiment.

Resolution: Adjust the output resolution (such as standard or higher quality). In this setup, changing resolution doesn’t affect credit usage, so you can choose the best quality your workflow can handle.

Number of results: Decide how many variations you want Grok to generate at once. If you’re trying to maximize credits, set this to 1 so you only pay for a single output per run.

Running Grok and generating your video

With everything connected and configured, you’re ready to run Grok. You can either select the Grok node and click a “Run selected” option, or use a general “Run” button in the interface, depending on how the platform is laid out.

Once you start the run, the platform will show a progress indicator as Grok processes your prompt and image. This may take a short while, especially for higher resolutions or longer durations. When it finishes, you’ll see a preview of your generated video.

If you’re happy with the result, close the preview and move on to exporting. If not, you can tweak your prompt, duration, or other settings and run it again—just remember each run uses credits.

Exporting and downloading your Grok video

To save your video, click on the Export node or an export button in the interface. The platform will then render the final video file based on the result Grok produced.

During export, you’ll see a rendering progress bar. When it’s finished, the video will automatically download to your device. You can then use it in your projects, post it on social media, or edit it further in your favorite video editor.

Managing and maximizing your free credits

Each account on this platform receives a daily credit allowance (for example, 150 credits). Different models and settings consume different amounts of credits. In the case described, using Grok for a short video costs around 36 credits, while another model like V03 might cost 90 credits for a similar task.

To make your credits last longer:

• Keep video durations short while you experiment.
• Generate only one result at a time instead of multiple variations.
• Use Grok for key shots and cheaper models for less important clips.

If you have multiple email addresses, you can technically create more than one account to get additional daily credits, though you should always respect the platform’s terms of service.

Using other models and tools alongside Grok

The same platform also includes other AI models for both images and video. You can generate your images directly inside the site before animating them with Grok, or you can continue using external image generators and only rely on Grok for the animation step.

If you’re exploring AI tools more broadly, it’s worth looking at other workflows that combine image, video, and design tools. For example, you might pair Grok-style video generation with structured design workflows similar to those in this guide to building real projects with Claude Design, or use it alongside money-making AI tools highlighted in this roundup of AI tools that can actually make you money.

Final thoughts

Grok AI may feel like a premium, paywalled tool, but through a credits-based platform you can still use it for free to turn your images into eye-catching videos. By setting up a simple node-based workflow—prompt, image input, Grok, and export—you can generate short clips in minutes, experiment with different ideas, and make the most of your daily credits without spending a cent.
