Sauna lives inside LINE: it reads the threads that need you, summarizes what you missed, and posts back once you approve — so LINE becomes a place work gets done, not just discussed.
Sauna + LINE
Connect LINE to Sauna and your team's conversations become a place work gets done. Sauna reads the threads that need you, summarizes what you missed, drafts replies in your voice, and turns a conversation into a ticket or a task — the LINE integration that acts, not just notifies.
Get engaged in interactive conversations with LINE users.

“Draft a reply to this LINE thread in my voice and post it once I say go.”
Connect
Connect it with an API key from the library, or ask Sauna in chat and paste the key into the form it opens. Add more than one account if you need to.
LINE is one of thousands of apps in Sauna's library. Anything not in the library, you add yourself with an API key or an MCP server — right from chat.
In context
Once LINE is connected, Sauna reads and acts on it from plain language — across the web app, Slack, email, iMessage, and Superhuman — and waits for your approval before it writes anything.
