Frequently Asked Questions
Are these AI tools free to use?
Yes. Every tool in this hub is free. Visitors can run a limited number of operations per day without an account, and signing in raises that daily allowance.
Do I need design or editing experience?
No. Each tool asks for a prompt, an upload or a URL, and does the work itself. You describe or supply what you want and adjust the result, rather than operating a timeline or a layer panel.
Can I use the results commercially?
You can use the media you generate or edit in your own projects. Usage rules differ by platform and by country, so check the terms of wherever you plan to publish before you rely on a result commercially.
Are my uploaded files kept private?
Uploads are used only to run the operation you asked for. Avoid uploading material you are not permitted to process, and keep your own copy of anything important.
Which AI tool should I start with?
If you need an image that does not exist yet, start with the AI Image Generator. If you already have a picture that is too small, low quality or has the wrong background, start with the AI Image Upscaler or the AI Background Remover instead.
