About

Datotek AI PSSD

You saved the photo. You remember the document. But where did you put it? Datotek AI PSSD is the companion for compatible Datotek portable SSDs. Connect and authorize your drive to browse your files on iPhone, describe what you are looking for, and get AI help reading and organizing your content. FIND PHOTOS WITH YOUR OWN WORDS Try a description such as "sunset at the beach" or "group photos with people." Look for relevant images without remembering their filenames. Results depend on completed indexing and the information available for each image. ASK YOUR DOCUMENTS Select or find a document, then ask for a summary, key points or information from supported documents and spreadsheets. Related files help you return to the source and check the answer. TURN FILES INTO A STARTING POINT Ask AI to organize selected content into editable presentations and other deliverables. Spend less time starting from a blank page. Review the content, numbers and references before using the result for important work. EXPLORE CREATIVE TOOLS Try AI image editing, multi-image fusion and video generation. These features require supported model services and a billing-enabled Google project; additional charges may apply. CHECK YOUR DRIVE Browse files, view storage capacity and, when a compatible health report is available, check the last recorded measurements. Health information shown on iOS is historical, not a live temperature or health reading. BEFORE YOU START • A compatible Datotek AI PSSD and a suitable iPhone connection are required. The app is not designed for every brand of external drive. • Online AI features require an internet connection, consent to data transfer and your own Google Gemini API key. Downloading the app does not include unlimited free AI usage. • AI requests send the necessary prompts and selected content through Datotek's service to Google Gemini. Your key is stored in this device's Keychain and transmitted over an encrypted connection when needed. • Quotas, model access and charges depend on your Google project and service availability. Initial indexing can take time. Keep your drive connected and follow the app's progress guidance. • AI may misunderstand or miss information. Check important answers against the original files and keep a separate backup of important data. Available in Traditional Chinese, English and Japanese. Support: datotek@datos.com.tw
