ChatbotsGoogle's multimodal assistant, strong on long supplier documents and visual inputs.
Gemini is Google's flagship assistant, wired into Search, Workspace and Android. It reads long PDFs, spreadsheets and product photos in one prompt, which suits export teams who juggle spec sheets, customs paperwork and buyer threads at once.
