Optional AI services
The editor's optional AI features connect, at your choice and with your own account, to third-party services such as Google Gemini, OpenAI, Anthropic, OpenRouter, Groq and Mistral, or to models running locally via LM Studio, Ollama or Draw Things. These are independent services with their own terms; all trademarks belong to their owners, and JUMI is not affiliated with or endorsed by any of them. No AI service is contacted unless you configure one.
File formats
Import: you can add images in PNG, JPG/JPEG, SVG, WebP and GIF. Transparency in PNG/WebP/SVG is preserved while editing.
Export: your ads can be saved as:
- HTML5 Banner: a self-contained ZIP package (index.html + assets) accepted by Google Ad Manager, DoubleClick, and most modern ad servers.
- Animated GIF: universal display-network format.
- MP4 video (H.264): for social feeds.
- Animated WebP: smaller, 24-bit colour, for the web.
- Static PNG and Static JPG: single-frame images.
Projects are saved as a portable .jumi.json file. Fonts can also be drawn from those installed on your own computer via the browser’s Local Font Access API. HTML5 exports embed fonts via the Google Fonts API at runtime.
