AI Prompt for Expanding a Blog Draft
Turn a thin draft into a rich article: this AI prompt adds depth, examples, and transitions to your blog draft without changing your voice. Free to use.
The prompt
You are a developmental editor who expands thin drafts into full, engaging articles. Context: I have a draft blog post about [TOPIC] that feels too short and shallow. The target audience is [AUDIENCE] and the desired tone is [TONE]. Here is my draft: [DRAFT] Task: Expand this draft into a complete article of about [WORD_COUNT] words. Keep my ideas, structure, and voice — your job is depth, not replacement. For each thin section, add: a concrete example or mini-story, one actionable tip, and a smooth transition to the next section. Strengthen the introduction with a stronger hook and expand the conclusion with clear takeaways and a call to action. Flag any claim that sounds like it needs a source with [NEEDS SOURCE]. Format: Return the expanded article in Markdown, preserving my original headings where they work and adding new H3s where a section needs splitting. Keep paragraphs to 2-3 sentences. Put a short "What I added" summary at the end listing the new examples and sections. Constraints: Do not change my core opinions or arguments. Do not pad with generic filler — every added sentence must give the reader something useful. Match my existing voice; if my draft is casual, stay casual. Do not invent personal experiences and present them as mine.
Variables to fill in
Replace each [variable] in the prompt with your own details:
[TOPIC] [AUDIENCE] [TONE] [DRAFT] [WORD_COUNT]
Example input
Example: TOPIC = 'freelance pricing', AUDIENCE = 'new freelancers', TONE = 'direct and honest', DRAFT = '<paste your 400-word draft>', WORD_COUNT = '1200'.
How to use this prompt
Paste your draft into the [DRAFT] variable and run the prompt. Review the 'What I added' summary first, then read the full piece to cut anything that doesn't sound like you.
Tips for the best results
- Expand the weakest section first in a follow-up run for even more depth.
- Delete any added example that feels generic — one real story beats three bland ones.
- Keep your original opening line if you love it; tell the AI to preserve it.
Frequently asked questions
Will it keep my writing style?
Yes, when you instruct it to match your voice and provide the draft as the style reference. Always do a final read-through.
What if my draft is only bullet points?
Use the bullet-expansion prompts in this library instead — they are built for turning notes into prose.
