Frequently Asked Questions

What's the difference between custom AI and ChatGPT?

ChatGPT is a general-purpose conversational AI designed for broad, generic use. Custom AI is purpose-built for your business: it knows your clients, follows your compliance rules, integrates with your systems, and handles your specific workflows. Think of ChatGPT as a Swiss Army knife and custom AI as a precision surgical tool.

Can ChatGPT replace a custom AI solution?

For basic tasks like drafting emails or brainstorming, ChatGPT works fine. But it can't access your CRM, follow your firm's compliance protocols, process documents through your approval workflows, or maintain persistent knowledge about your clients. Custom AI does all of this natively.

Is custom AI more expensive than ChatGPT?

ChatGPT costs $20-25/month per user for the Plus plan. Custom AI starts at $25,000+ to build but has no per-seat fees at scale. For a 50-person firm paying $25/user/month, that's $15,000/year, and you still can't integrate it with your systems. Custom AI typically delivers 3-10x ROI within the first year.

How long does it take to build custom AI?

A focused custom AI solution (like an AI sales agent, client portal, or document processor) takes 8-16 weeks from kickoff to production. A proof of concept can be delivered in 2-4 weeks to validate the approach before full investment.

Can I use ChatGPT while building custom AI?

Absolutely. Many firms start with ChatGPT for general productivity gains while building custom AI for their core competitive workflows. The key is knowing which problems need generic tools and which need purpose-built solutions.
