AI image generator for text prompts
The Problembo AI image generator turns a text prompt into a photograph, illustration, concept, or other visual. You choose the model, aspect ratio, resolution when available, and number of variants. The form shows the exact price before you start, so you can compare settings before paying for a run.
How to generate an image with AI
- Sign in and describe the image: the subject, setting, style, light, and composition.
- Choose a model. Use the examples in the model picker to compare its typical results.
- Select the available aspect ratio, resolution, and number of variants. Add a negative prompt or reference images only if those fields appear for the selected model.
- Check the quoted price, start the run, and download the result. Each new run is charged separately.

Some models require age confirmation before the first run. The catalog can change; the form is the source of truth for currently available models and controls.
For a specifically drawn look, use the AI anime generator. To change an existing picture rather than create a new one, use the AI photo editor.
How to write a useful prompt
Put the important information first. A practical structure is:
[subject], [setting and action], [type or style], [lighting and color], [camera and composition]
Examples:
A studio photograph of a ceramic coffee cup on a walnut table, soft window light,
warm neutral colors, close-up, shallow depth of field
An editorial illustration of a night train crossing a snowy valley, deep blue palette,
warm light in the windows, wide horizontal composition
A product concept for a compact orange camping lantern, isolated on a pale gray background,
three-quarter view, clean studio lighting
Keep the prompt internally consistent. Do not ask for a close-up and a wide shot at the same time.
If the model supports a negative prompt, list visible things you do not want, such as
text, watermark, extra fingers. Negative prompts do not guarantee that every defect will
disappear.
Reference images and consistent results
When a model supports references, the upload field appears in the form. Use a clear source image and explain what it controls: the character, pose, palette, or composition. For a series, repeat the same distinctive traits, clothing, colors, framing, and lighting in every prompt. A reference guides the model but does not copy every detail exactly.
Files, formats, and limits
- A prompt must contain 2 to 5000 characters.
- A run can return 1 to 12 images; the selected model sets the actual range.
- Available aspect ratios are 1:1, 3:4, 4:3, 9:16, and 16:9.
- Selected models expose 1K, 2K, or 4K resolution controls. Others use their own fixed output size.
- Models with reference support accept up to 4 JPG, JPEG, PNG, WebP, AVIF, HEIC, or HEIF files, up to 15 MB each.
- For each uploaded image, width plus height must be between 256 and 18,000 pixels.
Uploaded files and results are stored for 3 days. If the paid balance is at least $1 when a file is stored, it is kept for 30 days. Download anything you want to keep.
Pay for results, not a subscription
There is no subscription: each run has its own price, shown before launch. Free use requires an account and enough daily bonus balance. The bonus balance can be restored up to $0.60 once per UTC day and works only with supported models. Recent paying users receive it automatically; others claim it on the Daily bonus page. See pricing and bonus terms.
FAQ
Can I use the AI image generator for free? Yes, after signing in, within the available daily bonus and with models marked as accepting bonus funds. There is no unlimited free mode.
Can I see the price without signing in? Yes. Choose a model and settings to get a quote. An account is required to start generation.
Why do some settings disappear when I switch models? Reference images, negative prompts, resolutions, styles, and variant counts are model-specific. The form displays only supported controls.
Can I use an image commercially? Commercial use is allowed when that generation was paid from the paid balance, subject to third-party rights and the service terms.
How long are results available? Usually 3 days, or 30 days when the paid balance was at least $1 at storage time.
