FAQ

Questions about MōIcons.

Do I need an API key?

No API key is required for the ChatGPT connection. Use your ChatGPT account through a compatible desktop app. Alternatively, choose API key in the setup dialog or generation settings, select OpenAI, OpenRouter, or Google Gemini, and paste the key for that service. You can change or remove the saved key later.

What if ChatGPT is installed but cannot be found?

Choose Browse… in the ChatGPT connection screen and select the app in the macOS file picker. MōIcons checks the connection before saving the location. Use Change… to select another app or Check again after installing or moving it.

Can I choose the model and quality?

With an API key, settings show compatible image models available from your service. Refresh the model list to check availability. OpenAI offers Low, Medium, High, and Auto; OpenRouter options depend on the model. Google Gemini uses its default generation settings. Choices are saved separately for each provider. ChatGPT manages model and quality for its connection.

Can I use a Google Gemini API key?

Yes. Create a key in Google AI Studio, choose API key in MōIcons, select Google Gemini, and paste the key. Image generation requires paid Gemini API billing; a Gemini subscription alone does not cover API usage.

Can I use the exported icon in both an app and a DMG?

Yes. The exported .icns can be used for your macOS app bundle and your DMG volume. Configure the icon in your app or DMG build tools. MōIcons also saves a companion .iconset folder with all ten standard PNG representations.

Is it free?

MōIcons is free and open source. ChatGPT generation uses your account’s allowance and available credits. OpenAI, OpenRouter, or Google bills API generation separately. MōIcons adds no subscription.

How long does generation take? Can I stop it?

Timing depends on the service, model, and quality. Some requests take several minutes. You can stop generation and keep your previous variants. Requests already processed by the service may still count toward usage or charges.

Does it need internet? What stays on my Mac?

Generation requires internet and sends your prompt and reference image to the selected service. History, preview, and export work locally. Packaged builds can send launch and error diagnostics to Sentry when telemetry is configured.
