AI Image Generator:
Choose Models, Tune Settings, Edit Results

Secret Chat includes a built-in AI image generator that turns a written description into a picture — right inside the same private chat workspace you use for everything else. You do not need a separate app or account: pick the Image Generator, describe what you want, and the image appears in your conversation. What makes it flexible is that you are not tied to a single image model, every model brings its own settings, and any picture you create can be reworked with a single button.

For the wider product context — multiple models and local browser storage — see our main private AI chat page.

One tool, several image models

Different image models have different styles and strengths, so the Image Generator lets you choose the one that fits the job. You select a model from the Settings, and your choice is remembered for next time. The models available are:

• Grok Imagine 2.0 — xAI's newest image model and the default: bold, creative visuals, and the fastest way to get several variants of one idea at once.
• Nano Banana 2 — a fast, reliable everyday choice.
• Nano Banana Pro — a higher-end version for more detailed results.
• GPT Image 2 — OpenAI's image model, strong at following detailed instructions and text in images.
• Qwen Image 2 Pro — a flexible model with extra style controls.
• Seedream — another option with fine-grained style controls.

Because each model is a little different, it is worth trying the same idea on more than one to see which look you prefer. Results vary by model and by how you word your description.

Different models, different settings

At a glance, here are the settings each group of models offers:

When you open the Settings, you will see a Model selector at the top and, below it, the options that apply to the model you picked. The settings change to match the model — simpler models show fewer options, while the more advanced ones offer more control. The possible settings are:

• Model — which image model to use. Changing it updates the rest of the settings to match.
• Variants — how many different images to create from the same description at once, so you can pick your favourite. Some models allow a handful, others more.
• Aspect Ratio — the shape of the image, such as square, portrait, or landscape. Choose it to fit where the picture will be used.
• Resolution — how much detail the picture is rendered with: 1K, 2K or 4K, depending on the model. Most models start on 1K, the size they produce by default — the quickest and the cheapest in credits. Nano Banana Pro is the exception and starts on 2K, because on that model the larger size costs no extra credits, so opening it any smaller would simply give you less for the same price. Stepping up to 2K or 4K gives you a larger, more detailed picture, takes longer to generate, and costs more credits, so it is worth reserving for images you actually intend to print or use large. Not every model offers every step: Grok Imagine 2.0 goes up to 2K, and the Qwen and Seedream models have no resolution setting at all — they each render at their own fixed size, which for Seedream is already a large one.
• Image Style — a preset look (offered by some models) that nudges the overall style of the result.
• Negative Prompt — a short note of what you do not want in the image, for example “clouds, rain, snow.” Available on the models that support it.

For example, the Nano Banana models keep things simple with an aspect ratio and a resolution, while models like Qwen Image 2 Pro and Seedream trade the resolution choice for variants, a style preset, and a negative prompt. You do not have to learn all of this up front — sensible defaults are already set (including the resolution, which starts at whatever each model gives you the most for, so nothing costs more until you ask it to), and a Reset option puts everything back if you experiment.

Edit any image with one button

Every image you generate comes with two buttons beneath it: a Download button to save it to your device, and an Edit button (the pencil icon) to change it.

The Edit button is what makes refining a picture easy. Instead of starting over, you click the pencil and the image is placed back into your message box as a starting point. You then simply describe the change you want — “make the sky sunset orange,” “add a small boat,” “remove the text in the corner” — and generate again. The model uses your existing picture as the basis and applies your edit, so you can keep adjusting an image step by step until it looks right.

This image-to-image editing works with the models that support it, and it is the quickest way to fine-tune a result without re-describing the whole scene from scratch.

Tips for better images

• Be specific. Mention the subject, setting, mood, lighting, and style you have in mind — the more detail, the closer the result.
• Use variants. Generating a few at once gives you options to choose from in a single step.
• Set the aspect ratio first so the composition fits where you will use the image.
• Draft small, finish large. Finding the right description takes several attempts, and there is no point paying for extra detail while you are still experimenting. Once a result is close, raise the resolution and generate it again. (On Nano Banana Pro there is nothing to save by drafting below 2K — that step is free there.)
• Add a negative prompt (on models that support it) to keep out things you do not want.
• Refine with Edit. Get close, then use the Edit button to nudge the details rather than starting again.

Private by design

The Image Generator works the same private way as the rest of Secret Chat: it is an anonymizer. Your requests reach the image model with no name, account, or IP attached — the email you register with is used only for account access and payment, never to associate your images with you — and the pictures you create are kept in your browser's local storage on your own device, not a cloud gallery on our servers. The honest limit is the same too: this hides who is asking, not what the prompt says, so your description still reaches the chosen model provider to create the picture — keep personal or confidential details out of it. For more on how this works, see our private AI models page.

One more thing worth knowing when you refine a picture over several messages. Most image models can only be handed a single self-contained description — never a conversation — so a small helper model at OpenAI first rewrites your chat into that one description; without it, a follow-up like “make it blue” would mean nothing to a model that never sees what came before. (The Nano Banana models read the conversation directly and skip this step, as does the very first picture in a chat.) That helper call travels exactly like every other request — anonymously, under our own credentials, never linked to you — and every model that took part in a message, helper included, is listed in that message's Session Privacy Report.
