The matrix[1] team is working on an axolotl implementation meant to be used pluggably: https://matrix.org/git/olm/

I searched for axolotl and got some cute pictures but not much information. Why this thing rather than OTR?

OTR has some major shortcomings - in the classic implementation, it doesn't do group chat and it requires both parties to be online at the same time to synchronise the cryptographic ratchet. The best explanation of why Axolotl is better is https://whispersystems.org/blog/advanced-ratcheting - or if you prefer a more comprehensive spec, we've published one at https://matrix.org/docs/spec/olm.html.

Anyone wanting to know more about Olm & Matrix's Axolotl support might be interested to flip to the end of https://matrix.org/~matthew/2015-06-26%20Matrix%20Jardin%20E...

Hi indeed.

Are there any plans for formal standardisation, review or the like? The docs look cool but at this point I'm suspicious of any single-vendor cryptography.

yup, we will get it properly reviewed once complete.
