#10 Prompting Technique

Fill-in-the-Blank Prompts

Provide structure, let AI complete the missing pieces.

Overview

What It Is

Fill-in-the-blank prompts provide AI with a template where most content is fixed and AI only generates specific missing elements. You control the structure and framework, while AI completes the gaps based on your guidance.

Fill-in-the-blank prompts maximize control while minimizing effort: you get consistent formatting across outputs because the template stays fixed, but each completion is customized based on the specific context you provide.

The Mechanics

Why It Works

By providing most of the content structure, you focus AI's generation on specific gaps rather than asking it to create entire responses from scratch. The fixed template serves as strong context for what type of content should fill each blank.

Fill-in-the-blank format also makes outputs immediately usable without editing. Since the structure is already correct, you can directly use AI's completions in documents, communications, or workflows without reformatting.

Pro Tips

  • Use clear placeholder markers: [Brackets] or __underscores__ make blanks obvious to AI and reduce the chance it fills in the wrong sections.
  • Include length guidance: Specify '1-2 sentences' or '3-5 items' for each blank so AI knows how much to generate.
  • Provide example completions: Show AI what good blanks look like with a short example — it calibrates style and depth better than describing it.
  • Save successful templates: Build a library of proven templates for repeated use. A good template is an asset worth keeping.
  • Iterate on templates: Refine based on what AI consistently gets wrong. One or two refinement cycles usually locks in a reusable version.
