Chat SDK for n8n

An n8n community node that wraps Vercel's Chat SDK: one workflow answers mentions on eleven chat platforms — Slack, Mattermost, Microsoft Teams, Telegram, Discord, Notion, WhatsApp, Twilio, Messenger, Instagram and Linear — through one shared thread and message model.

Three nodes: Chat Trigger (webhook or socket), Chat (post, react, edit, ephemeral) and Wait (resumes the workflow on a button or select click). Per-platform capability gaps are measured from each adapter's installed code, so unsupported operations are hidden instead of failing at runtime.

Self-hosted n8n only — n8n Cloud accepts verified community nodes, and verification forbids the runtime dependencies the Chat SDK needs.
