Before sending
Open a chat. Drop or paste files on your computer, or select Gallery/Files from the attachment button on your phone. Preview video, images, PDF and audio; documents show their name, size and internal viewer. Add a caption, add/remove items, then Send.
Follow progress
Compression and upload progress includes Cancel. Originals stay on your device. On desktop, confirmation stays inside the conversation and the sidebar remains usable.
Share from another app
Android: Share → KOCHAT, then choose a chat. iOS: documents and videos exposed as files use Open/Copy to KOCHAT; availability depends on the source app. You may also choose media from KOCHAT Gallery. Confirmation always appears before sending.
After sending
Play video/audio in the chat and open PDF/documents in the internal viewer. Save formats that require a separate compatible app. Server size, type and safety checks still apply.
