n8n AI & LLM Workflows

Fully Automated AI Blog Publishing Pipeline to WordPress

The content calendar has forty topics sitting in a spreadsheet, and every single one of them needs the same tedious sequence before it becomes a published post: open a doc, write a draft, format the headings, write a meta description, log into WordPress, paste everything in, fix the formatting that broke during paste, and finally hit save. Multiply that by forty, and it's easy to see why half the calendar never actually gets written. This guide builds an automation that handles the repetitive middle part of that process. Add a topic to a content calendar, and a fully formatted article — complete with a meta description — shows up in WordPress as a draft, ready for a human to review, edit, and hit publish. No writing from a blank page, no manual formatting, no copy-paste errors. This guide's specific technical focus covers two things that catch people off guard the...

Automate Meeting Summaries With n8n (Whisper + GPT)

A one-hour meeting ends, and three people walked away with three different memories of who agreed to do what. Nobody wrote it down in real time, the recording sits unwatched in a shared drive, and by the following week, half the action items have quietly evaporated. This guide builds an automation that turns a meeting recording into a clean, organized page in Notion — a written summary and a clear list of action items — without anyone needing to relisten to the recording or type a single note. The moment a recording gets uploaded to a Google Drive folder, this workflow transcribes it, extracts what actually needs to happen next, and files it away automatically. This is also a slightly more advanced build than a single-API workflow, since it chains two separate AI services together — one that turns speech into text, and a second one that reads that text...

Automate PDF Invoice Data Extraction With n8n

An invoice lands in the accounts inbox as a PDF attachment. Someone opens it, squints at the total, retypes the vendor name, the amount, and the date into a spreadsheet by hand, and moves on to the next one. Multiply that by every supplier, every month, and it's easy to lose an entire afternoon to typing numbers that were already sitting there in the email the whole time. This guide builds an automation that removes that step entirely. The moment an email with a PDF invoice arrives, n8n reads the file, pulls out the vendor name, amount, and date using an AI model, and drops that information straight into a Google Sheet — no retyping required. This guide also has a specific technical focus worth understanding properly: how n8n handles file attachments, and why they need to be converted to a text format called Base64 before an API can read...

Automate Support Ticket Triage With Gemini + n8n

A billing complaint sits in the general support inbox for six hours because nobody noticed it between forty other emails about password resets. By the time someone finally reads it, the customer has already emailed twice more, and the tone in that third email is a lot less patient than the first. This is the exact problem this workflow solves. Every new support email gets read by Google's Gemini API the moment it arrives, sorted into Billing, Tech Support, or Sales, checked for how upset or urgent it sounds, and dropped straight onto the correct team's board — before a human ever opens their inbox. This guide builds that automation in n8n, step by step, written for someone who has never touched n8n or an AI API before. It also covers the one part that trips up most people building this kind of workflow: getting Gemini to return clean, predictable...
