How to use BlogGen Studio (user guide): First, add your Gemini, Groq, or OpenRouter API key in the Settings tab (keys are stored only in your browser). Then, in the Generate tab, add one or more blog post rows. For each post, enter a Topic/Title (required), choose a writing style, add personal notes, expert quotes, YouTube URLs, or upload images. If you have a circuit schematic or PCB photo, click the "Circuit / PCB Analyser" panel, upload the image, and the AI will analyse the circuit. For troubleshooting content, click "Auto-Find Problems" to search the web for real-world issues and solutions related to your topic or circuit — the AI will fill problem/solution/discussion entries automatically. You can also manually add problems. When ready, click "Generate All" for all rows or the individual Generate button per row. The post streams live as HTML or Markdown, includes SEO meta comments (with a strict 150-character description limit), and shows a preview. Export your posts as JSON or copy the HTML to paste into Blogger. That's it — perfect for engineering, electronics, and tutorial blogs.
