Gmail → OpenAI → Slack

Each new Gmail message is summarized by OpenAI and the summary is posted to Slack.

지메일에 새 메일이 오면 OpenAI가 요약해서 슬랙에 올려요.

Steps

  1. When when a new email arrives in gmail — Gmail node
  2. Then summarize it with openai — OpenAI node
  3. Then send the summary to slack — Slack node

Fields to fill (4)

The file has every node wired up. These are the blanks only you can fill (your form, your sheet, your words).

NodeWhat to do
OpenAIfill modelId (Model)
Slackcheck select = 'channel' (first option; pick yours)
Slackfill channelId (The Slack channel to send to) — only if select = channel
Slackfill text (The message text to post) — the AI step's output: run that node once in n8n and pick its output field

Accounts to connect (3)

In n8n, pick or add a credential on each node — one of the types below.
