Volafile combines file-sharing and chat, while adding a bit of privacy too.
Create a room and send its link to anyone you want to participate in it. Any file will stay online for 48 hours, after which it is automatically deleted.
It also has file-sharing between all of you, but it also adds Google Docs, Sheets, and Presentations so you can collaborate with your files so you can brainstorm while still having a chat.
If you like how Webroom functions, feel free to register for an account.
This gives you a few additional features like session history and a meeting scheduler.
Cyph encrypts all your video and voice calls, along with your chats.
Even the documents you share, be it photos or videos, are encrypted, so they are safe from data leaks.
It’s an end-to-end encrypted chat service that works on the browser, and even lets you share files.
