Auto tag blog posts

★ 6.0 · n8n · medium · 12 nodes

Auto tag blog posts is an n8n automation template that automatically assigns tags to blog posts using large language models. Reach for it when a backlog of untagged articles is piling up, when a content team publishes faster than editors can categorize, or when you want tag assignment to happen the moment a post hits the CMS. Trigger: webhook — the workflow fires as soon as post data arrives, calls OpenAI or Anthropic to generate relevant tags, logs the result to Google Sheets, and sends a Slack notification. Direction: enriching existing content with metadata, not generating or publishing it (for auto-posting images to Pinterest, look for dedicated Pinterest workflow templates). Exact node count is unavailable from the source; stack — n8n with OpenAI, Anthropic, Google Sheets, and Slack integrations, webhook trigger. Works well for editorial teams and content operations that track publications in spreadsheets; not suitable for tagging non-text assets or pipelines that must avoid external AI APIs.
