An n8n agent finds happy-hour deals daily and saves its builder 58 hours a week
In plain words
Five daily n8n workflows search the web for happy-hour specials and publish them to the database behind the site.
What happened: 58 hours saved in a week, for about $36 a month in running costs (their own figures).
These numbers come from the builder and haven't been checked independently.

How to do it yourself
Our suggested steps. The company didn't publish theirs.
- 1
List the sources you check by hand each day.
- 2
Build an n8n flow that searches or scrapes them on a schedule.
- 3
Add an AI step that pulls out clean fields with the prompt below.
- 4
Save to your database and spot-check 20 rows.
- 5
Run daily; merge flows once stable.
The instructions to give the AI
Paste this into ChatGPT (the free plan is fine), swap the [brackets] for your details, and test it on a few real examples.
This is one part of the setup. It won't connect to your phone, inbox or other apps on its own; the steps above cover that.
Agent instructions (prompt)
From this web page text about [venue], extract happy-hour details as JSON: days, start time, end time, drink deals, food deals. If something isn't stated, leave it empty. Don't guess.
[Highlighted] = replace with your own details before you run it.
What you should get back: {"days":"Mon-Fri","start":"16:00","end":"18:00","drinks":"$5 pints","food":"half-price wings"}
