n8n AI Article Automation: Gemini + Wikipedia + Gmail

Generate a ~500-word SEO article automatically—research with Wikipedia, write with Gemini, log to Google Sheets, and deliver via Gmail

This n8n workflow turns an article request into a finished, SEO-edited post. It collects your topic, audience, and SEO keyword via an n8n form, uses Google Gemini with Wikipedia research, then drafts and optimizes the article (~500 words). Finally, it logs results to Google Sheets and emails the completed article through Gmail.

What this workflow does

• Receives the request through an n8n form that captures: recipient email, topic, audience, and the SEO keyword.
• Researches with Gemini + Wikipedia using a Gemini agent configured with the Wikipedia tool to produce structured notes (including key points, numbers, and misconceptions).
• Drafts the article with Gemini in the target audience’s style, using only the research notes to produce a ~500-word article.
• SEO-edit and optimize the draft with Gemini by naturally incorporating the provided keyword and generating an SEO title and meta description.
• Extracts structured outputs (article body, title, meta description, and requester email) from the editor output.
• Logs to Google Sheets by appending the article details to a chosen spreadsheet/tab (e.g., an “Articles” tab).
• Sends via Gmail the completed article to the requester’s email.

Use cases

• Automation engineers who need an end-to-end “article request → delivery” pipeline in n8n.
• SaaS operators collecting marketing topics from users and automatically emailing finished SEO drafts.
• Teams managing recurring content production without manual research, writing, and spreadsheet tracking.

Technical details

• Google Gemini (PaLM) API via n8nn8n-nodes-langchainagent with the Wikipedia tool for research.
