## Questions about Sevli

### What can I make with Sevli?

You can generate images from text and edit reference photos on Sevli at sevli.app. Product images, portraits, posters, illustrations and creative effects are supported. The current public product is for images.

### Which image models can I use on Sevli?

Sevli offers 10 image-model options across GPT Image, Nano Banana, Seedream and Qwen. Each model page has examples, prompts and supported settings.

### Do I need an account?

Public pages and examples can be read without signing in. Generation, editing, purchases and account history require sign-in. Email/password registration currently requires email verification.

### Can I try Sevli for free?

When enabled, eligible Google-linked accounts can claim 100 welcome credits, valid for 7 days. Eligible Google-linked accounts can claim 10 daily credits once per UTC day. Daily credits expire at the next UTC midnight. Email/password registration alone, including verified email accounts, does not qualify for these promotional credits.

### How many images do my credits cover?

For example, a GPT Image 2 1K image without references uses 9 credits. Other models and editing tools have different quotes. The pricing page estimates usage for the task you choose.

### Will my image have a Sevli watermark?

Accounts without a completed qualifying payment get a visible Sevli watermark. A qualifying paid subscription or credit-pack payment removes the visible Sevli watermark from generated images. Provider provenance marks may remain.

### What happens if generation fails?

Failed generation returns the affected credits under their original validity rules. This is separate from a cash refund. Billing disputes and refund requests are reviewed individually under the published refund policy.

### How do I get support or report content?

Email support@sevli.app or submit a support ticket while signed in. Include the relevant order or image link when needed, without unnecessary sensitive information.
