One named purpose
Policy Q&A, proposal review, coaching, research or another role people can recognize instantly.
Custom GPTs
Package one role into a clear assistant
Combine instructions, knowledge, starters and capabilities so people can open a purpose-built version of ChatGPT and know exactly what it is for.
No-codeKnowledgeCapabilities
Use a GPT when the assistant itself should be reusable
Same reference material
The assistant needs the same instructions and files every time someone opens it.
Selected capabilities
Add web search, images, data analysis, apps or custom actions where they support the workflow.
Put the right thing in the right place
Instructions
Rules, tone, workflow, definitions, response structure and what the GPT should do.
Knowledge
Handbooks, policies, documentation and source material the GPT should reference.
Test before sharing
Use realistic prompts in Preview. Long or conflicting instructions reduce consistency, and knowledge files do not replace clear behavioral guidance.
Understand how a GPT behaves when people use it
A custom GPT is a separate configured assistant, not a continuation of every preference and conversation from normal ChatGPT.
Each conversation starts fresh
GPT conversations do not use your saved memory, global Custom Instructions or earlier GPT conversations. Information that must persist should be included in the configuration or supplied again.
Builders do not see individual chats
The person who created a GPT cannot inspect each private conversation people have with it. However, external Apps or APIs may receive relevant information when the GPT uses them.
Capabilities need a purpose
Adding more tools does not fix unclear instructions. Start with a well-defined role and workflow, then enable only the capabilities that the assistant genuinely needs.
