Slightly off-topic, but I’ve been searching for a long time for something like this, but for text chat: go to a website; create a room; share a code/link with others; people join and chat; then at some point in the future the room simply disappears (you can save a log if you want). Ideally anonymous with the best possible cryptographic implementation.

Has anyone stumbled upon something similar? I hate having to register and login to every chat platform, especially bloated ones like Discord and Slack. The closest one to what I want is gitter but it requires a GitHub signin.
