To use Lumo's file analysis feature, you must first log in to your Proton account (either free or paid) and then click on the File Upload icon in the chat screen to choose between locally stored files or files imported from the Proton Drive cloud. After uploading, enter commands such as "Summarize this contract" or "Translate to French". Note that free users support smaller files (exact size is not specified, but should be smaller than the Plus plan), while Lumo Plus users can upload larger files. Supported file types are mainly common document formats, such as PDF, Word, etc., but the specific format restrictions need to refer to the official instructions. This feature is particularly suitable for professionals who need to quickly process documents such as contracts and reports.
