Leverage ChatGPT Projects to build, refine, and maintain a custom AI writing assistant that reliably reflects your brand’s unique voice—scalable across blogs, emails, social, and more.

Prerequisites

• ChatGPT Pro with Projects enabled
• Up to 20 files (Markdown, TXT, PDF, or images, each < 5 MB)
• Human reviewers for quality control

Step 1: Create Your “Brand Voice AI” Project

1. In ChatGPT, select Projects → New Project, name it Brand Voice AI.
2. Upload exactly these 7 files (leave room for future updates—max 20 total):
   1. Guardrail_ToneRules.md
      • Lists tone guidelines, banned words, style rules.
   2. Guardrail_ProductSpecs.md
      • Official product facts for citation.
   3. Guardrail_LegalGlossary.md
      • Compliance and legal phrasing rules.
   4. Prompt_BlogIntro.md
      • Blog introduction prompt template.
   5. Prompt_EmailTemplate.md
      • Email copy prompt template.
   6. QC_StyleCheck.md
      • Quality‑check prompt.
   7. Dataset_SampleExcerpts.md
      • 5–10 short excerpts (pauses, headlines, sentences) from your best content with metadata annotations in Markdown.

Note: All other content (full assets, CSVs, external links) must live outside Projects. You’ll paste or quote relevant snippets manually when needed.

Step 2: Define & Use Prompt Templates

1. Blog Intro Template (Prompt_BlogIntro.md):

   markdown
   Copy
   # Blog Intro Template
   You are the BrandVoice Assistant.
   Write a 150–200 word blog introduction on [TOPIC].
   • Audience: [Audience descriptor]
   • Tone: [e.g., warm + witty]
   • Do not use banned words from Guardrail_ToneRules.md.
   • Cite any product facts from Guardrail_ProductSpecs.md (append “(Source: ProductSpecs.md)”).
   • Optionally mirror style from these excerpts:
     > [Paste 2–3 short lines from Dataset_SampleExcerpts.md]
   
   

2. Email Copy Template (Prompt_EmailTemplate.md):

   markdown
   Copy
   # Email Copy Template
   You are our EmailVoice Assistant.
   Draft an email with:
   • Subject lines: [2 options]
   • Preheader: [text]
   • Hero headline (≤ 40 chars)
   • Body: 3–5 benefit bullets
   • CTA text: [e.g., “Shop Now – 20% Off”]
   • Tone per Guardrail_ToneRules.md
   • Cite specs from Guardrail_ProductSpecs.md
   • Reference style from excerpts in Dataset_SampleExcerpts.md
   
   

Step 3: Generate Content with Explicit Retrieval

1. Start a chat inside Brand Voice AI.

2. Load your template by filename and supply variables:

   text
   Copy
   Use Prompt_BlogIntro.md.
   Replace [TOPIC] with "3 Ways to Boost Focus".
   Replace [Audience descriptor] with "busy professionals".
