Slack Translation Bot
The Slack translation bot that takes up minimal space.
Translations appear inside the original message — no reply messages, no clutter. Your messages are never stored.
Battle-tested in production for years across teams of dozens — trusted daily for real work.
Features
Minimal Space
Other translation bots send reply messages that clutter your channel. Translation Bot embeds translations directly inside the original message — minimal footprint, clean conversation flow.
Your Messages Are Never Stored
Message text is processed in memory and immediately discarded. We do not log, cache, or store your messages — ever. All communication is encrypted with TLS.
Auto Language Detection
Any non-English message is automatically detected and translated to English. No commands needed — just write naturally in your language.
65+ Languages via Emoji
React with a flag emoji to translate any message into that language. Covers East Asia, Southeast Asia, South Asia, Middle East, Europe, Africa, and more.
Custom Context per Channel
@mention the bot with your team's proper nouns and terminology — context is saved per channel and included in every translation.
Translation Skip
Prefix your message with !nt to skip auto-translation. Useful for code snippets or intentionally non-English text.
