Credentials you'll need

Each integration node will prompt for credentials when you import. We strip credential IDs before publishing — you'll add your own.

How this works

Transform lengthy PDFs into engaging blog posts effortlessly, saving hours of manual rewriting for content creators and researchers. This workflow suits bloggers, marketers, and educators who need to repurpose documents into polished articles without losing key details. It begins with uploading a PDF via a simple form trigger, then leverages AI to extract and refine the text before publishing directly to Ghost, ensuring your content reaches your audience seamlessly.

Use this workflow when you have a single PDF ready for quick conversion to a blog post, especially for time-sensitive topics like reports or whitepapers. Avoid it for highly technical PDFs requiring custom formatting or when integrating with multiple platforms beyond Ghost. Common variations include swapping Ghost for WordPress or adding image extraction for richer posts.

About this workflow

📄🛠️PDF2Blog. Uses stickyNote, formTrigger, extractFromFile, ghost. Event-driven trigger; 12 nodes.
