eeumsae runs your business automations without you standing up a server or a cron job.
Call an API on a schedule or a webhook, pull out just the fields you need, summarize them with AI,
and send the result to Slack — turn it on once and it keeps running.
A single automation in eeumsae is called a workflow.
A workflow is one picture: nodes connected by edges.
[⏰ Every day 9 AM] → [⚡ Fetch orders API] → [⟐ Keep only what matters] → [✦ AI summary] → [💬 Post to Slack]
start (trigger) external call data transform AI call send message
Every workflow starts from exactly one ENTRYPOINT node. There are two ways to start it — a webhook (when someone calls it) or a schedule (at a fixed time).
Everything in between is a CALL node. You decide what it does by choosing an integration.
To pass values between nodes you write expressions like ${nodes.previousNode.response.body.field}.
There are three ways to build one. Pick whichever you like — you can mix them freely.

Labels are written exactly as they appear on screen.
The app is available in English and Korean. It follows your browser language and you can switch it
on screen. This guide describes the English interface — if you use it in Korean, switch this guide
with the 🌐 button at the top.
The example YAML is written so that it works when pasted as-is. You do still have to replace values like channel IDs and API keys with your own.
Features may change during the beta. If the docs and the screen disagree, tell us at contact@eeumsae.com.
