GPT Forge

Build a complete custom GPT from one description

Open ChatGPT Builder

Turn one idea into a ready-to-publish GPT

Describe the GPT you want. Forge writes the prompt, your AI tool fills in every field, and everything lands in a clean layout that matches ChatGPT's builder, with a copy button on each box.

Step one

Describe your GPT

In plain words, tell Forge what you want the GPT to do, who it is for, and what it should produce. A few sentences is enough. Rough wording is fine.

Your GPT is ready to assemble

Open ChatGPT's builder, then copy each box below into the matching field.

Do this or your GPT will not work

In ChatGPT's builder, scroll below Knowledge to the Capabilities checkboxes and tick the ones listed for your GPT further down this page.

  1. If your GPT makes images and DALL-E Image Generation is left unticked, it will reply that it cannot create images.
  2. Tick every capability shown in the Capabilities box below, and leave the rest unticked.
  3. Save, then open a fresh chat and try one of the conversation starters.
