but as far as I know there is only one implementation, and it's underdocumented. The protocol itself seems well specified, but it doesn't use "standard" primitives https://otr.cypherpunks.ca/Protocol-v3-4.1.1.html
And UIs are usually not great (you have to check a shared secret via a trusted channel).
There are also talks of an OTRv4, shared by XMPP and IRC: https://github.com/ircv3/ircv3-ideas/issues/67 but the protocol is even more complex, I even have a hard time following the introductory sections of its specification.
