Blog Post Writer from Outline

Why this prompt works

The constraints score is 35 on this prompt, which sounds bad but is actually intentional: it gives the model lots of room to interpret the outline as substantive prose rather than a templated expansion. The eight requirement set carries the work instead. Most useful is the explicit list of banned phrases ('In today's world', 'It's important to note', 'In conclusion', 'At the end of the day'), which removes about 30% of the model's default blog vocabulary in one line. The 'short paragraphs (2-4 sentences max)' rule and the 'as if explaining to a smart colleague' tone fix the two ways generated blog posts most commonly fail: long blocks of text and a register that's either too breezy or too formal.

When to reach for it

• You've outlined a blog post and need to expand it into prose without losing the structure you spent thinking on.
• You're managing a content calendar and need to turn briefs into drafts at speed without dropping quality.
• You're a non-native English writer producing in English and want a draft to edit rather than write from scratch.
• You're A/B testing two intros for the same post and need both written in a comparable voice.

How to customise it

The audience field is what determines whether the post reads as authoritative or basic. 'Marketing managers at B2B SaaS companies' produces output that assumes shared vocabulary; 'people new to marketing' explains things the first audience would find patronising. Set the goal field deliberately ('inform' produces explanatory prose; 'persuade' adds calls to specific actions; 'entertain' allows looser structure). The word count input matters more than people expect: 800 and 2,000 produce structurally different posts, not just longer ones, so set it based on what the keyword actually warrants.

What good output looks like

A formatted post with H2 and H3 subheadings matching the outline. Paragraphs are short, often 2 or 3 sentences. Real-world examples are woven into each section rather than bunched at the end. Bold key takeaways appear inline. The intro hooks with a stat, claim, or scenario; the conclusion ties back to the opening question. The banned phrases are absent. Length comes in within ~10% of the target word count.
