I am the creator of u/JudoTechniquesBot which is a reddit bot that runs on the r/bjj subreddit. The bot scans comments made on the r/bjj for judo techniques named in Japanese and comments and provides the translated English name and other potential names (wrestling, bjj specific, etc) for the techniques. In addition to the english translations, it also provides links to youtube videos that demonstrate the technique.

The code for the bot can be found on github. You should also checkout out the stats.
