How to Create a Cover Letter Generator GPT

Updated on:
May 12, 2026
By:
Madhav Bhandari
Use this interactive demo to learn how to build a custom cover letter generator GPT in ChatGPT.

Quick summary

This tutorial shows you how to create a custom GPT in ChatGPT that generates cover letters by configuring a name, description, instructions, conversation starters, and knowledge files — then publishing it with your preferred access settings.


Steps

  1. On ChatGPT's main interface, navigate to the left-side panel and click 'Explore GPTs'.
  2. Tap 'Create' at the top-right corner to get started.
  3. Switch to the 'Configure' tab.
  4. Click the 'Add' icon to upload a display photo representing your cover letter generator GPT.
  5. Enter a unique GPT Name and Description into their respective input fields.
  6. Write detailed guidelines describing the purpose, behavior, and capabilities of your GPT in the 'Instructions' input field.
  7. Add prompt examples to guide users by typing them into the 'Conversation Starters' input field.
  8. Click 'Upload Files' under the Knowledge section to add reference documents for your GPT.
  9. In the Capabilities section, tick the checkboxes for the GPT functions you want to enable, and optionally configure Actions for third-party integrations.
  10. In the Preview Area, type a test prompt and click 'Submit' to try out your cover letter generator GPT.
  11. When satisfied, tap the 'Create' button at the top-right corner to finalize your custom GPT.
  12. Select your preferred access configuration and tap 'Save'.
  13. Your cover letter generator GPT is now created and published.

📌 Why this matters

Building a custom cover letter generator GPT in ChatGPT lets job seekers and career coaches automate the creation of tailored, professional cover letters at scale. By configuring a dedicated GPT with specific instructions, conversation starters, and reference knowledge, users can deliver consistent, high-quality output without starting from scratch each time. This approach saves significant time during job applications and ensures every cover letter is personalized to the role and candidate. Custom GPTs also support third-party integrations via Actions, making it easy to embed AI-powered cover letter generation into existing HR or career tools.
