To write articles with Jasper AI, log in and select "Your Content," then "+ New from template." Choose the "Blog Post Starter" workflow to create long-form content. Provide context, generate blog post titles, and select one. Craft an intro paragraph, add keywords, and choose an output. Create a post outline using the "Blog Post Outline" template, pick an output, and format headings. Use the "Paragraph Generator" template with descriptions, keywords, and tone for paragraphs. Repeat for each section. The process yields around 500-800 words of AI-generated content, which can be refined or expanded using other templates.
