In Lesson 2 you built a single workflow. That's a tool. A connected set of workflows, where AI sits in the middle reading from and writing to all your apps, is a system. This lesson shows you which tools matter most and how to wire AI into three of the highest-leverage ones.
The 10 Integrations That Matter Most
n8n connects to hundreds of apps, but freelancers really only need a handful. These ten cover almost everything worth automating — and what AI adds to each:
| Tool | What You Connect | What AI Does |
|---|---|---|
| Gmail / Outlook | Incoming emails | Classify, summarise, draft replies |
| Google Sheets | Form data, lists | Analyse, enrich, summarise |
| Slack | Messages, alerts | Route, respond, notify |
| Notion | Pages, databases | Organise, tag, summarise |
| Typeform / Tally | Form submissions | Qualify leads, send responses |
| WordPress | Posts, pages | Generate drafts, meta descriptions |
| Airtable | Records | Enrich data, update fields |
| Calendly | Bookings | Send prep briefs, follow-ups |
| Google Docs | Documents | Edit, reformat, summarise |
| Webhooks | Any app with an API | Unlimited custom connections |
The Email Triage Workflow
Your inbox is the highest-volume, lowest-leverage place you spend time. This workflow reads each new email, classifies it, and routes it so you only touch what matters.
- Trigger: Gmail node fires on a new email.
- Process: an AI node reads the subject and body and returns a single label.
- Route: an IF node sends "urgent" emails to a Slack alert and files the rest.
The whole thing hinges on a tight classification prompt that forces a one-word answer:
The Lead Qualification Workflow
Not every form submission deserves your time. This workflow scores each lead so you chase the good ones and auto-respond to the rest.
- Trigger: Typeform/Tally node fires on a new submission.
- Process: an AI node scores the lead 1–10 based on budget, timeline, and fit.
- Route: high scores get a personal notification; low scores get a polite templated reply.
Save Qualified Leads to a Sheet
Add a Google Sheets node at the end that logs every qualified lead with its AI score and timestamp. Over a few months that sheet becomes a goldmine for spotting which lead sources actually convert.
The Content Repurposing Workflow
You already create good content. This workflow squeezes ten times the mileage out of it — turning one blog post into a week of social captions automatically.
- Trigger: WordPress node fires when a post is published.
- Process: an AI node reads the post and writes five platform-ready captions.
- Output: a Notion node saves them into your content calendar, ready to schedule.
You don't need to automate everything at once. Pick the one tool you use most and build one workflow for it this week.
