Show HN: Kotobase: Slack translation for EN/JP teams

Sharing a simple plug-in that auto-translates messages between English & Japanese in Slack. We developed it to solve our own problem: getting a diverse multilingual (English & Japanese speaking) team on the same page. It’s dramatically improved our alignment and team cohesion. If you happen to have the same problem, give it a whirl. We (Fujitsu Launchpad) cover up to 1M tokens/month for free; after that, just use your own OpenAI API key.
