Build AI-Powered n8n Workflow Automation

I want to stitch together a fully automated workflow in n8n that is assisted by an AI agent. The core objective is hands-free workflow automation spanning Google Workspace, Salesforce and Slack so I can quit the repetitive busywork and focus on higher-value tasks.

Here is the scope I have in mind
• Email management – an n8n flow should watch Gmail, classify inbound messages with an AI classifier (OpenAI, LangChain, or your preferred library), file or label them, surface high-priority threads in Slack and, when relevant, create or update Salesforce records.
• Data synchronisation – contacts, deals and support tickets must stay in sync between Salesforce and Google Sheets / Drive with conflict resolution rules.
• Task management – when certain triggers fire (e.g. a deal moves stage, an email arrives from a VIP, or a Slack message is starred) the automation should open the appropriate task in Salesforce and send a confirmation or reminder in Slack.

Key expectations
• Everything is orchestrated in n8n and delivered as reusable .json workflows.
• The AI component runs server-side, makes decisions, and feeds its output back into the flows.
• Clear, step-by-step deployment notes so I can reproduce the setup on my own VPS.
• All work must be demo-ready: I type a test message or change a record and see the chain react across all three platforms without manual touch-points.

Acceptance criteria
1. A sample Gmail, Slack message or Salesforce update triggers the chain within 5 seconds.
2. No data loss or duplication during sync runs.
3. Setup passes my walkthrough on a fresh n8n instance.

If you have already wired n8n with Google, Salesforce or Slack, and enjoy building smart agents, this will be a quick win for both of us.
