Custom GPTs and AI Assistants for Business: Uses, Setup and Risks
Short answer
A custom GPT or private AI assistant is an AI chat tool set up with your instructions, documents and tone so staff can get consistent help on specific tasks: drafting proposals, answering product questions, summarising policies or preparing customer replies. They are quick to set up on platforms such as ChatGPT, Claude or Microsoft Copilot, but need clear data rules, up-to-date documents and human review, especially for anything customer-facing.
Key takeaways
- ✓Build assistants for specific, repeated tasks.
- ✓Use approved, current documents.
- ✓Set data rules before uploading anything.
- ✓Keep humans reviewing outputs.
