ChatGPT vs. Custom AI Assistant: Which Do You Need?

ChatGPT is amazing. But it's not always the right tool.

When ChatGPT Is Enough

Personal Productivity

Writing, brainstorming, research, coding help.

Generic Tasks

Tasks that don't require specialized knowledge.

One-Off Questions

When you need an answer, not a system.

Internal Use

Team members using AI as a tool.

When You Need Custom AI

Customer-Facing

ChatGPT doesn't know your products, policies, or brand.

Specialized Knowledge

Your expertise, methods, and content.

Consistent Branding

Custom personality, voice, and boundaries.

Monetization

ChatGPT can't earn revenue for you.

Data Privacy

Your content stays yours, not in OpenAI's training.
