How to Build Your AI Agent MVP (Minimum Viable Product)
Before launching a full-featured AI agent, you need to create a simple working version known as an MVP (Minimum Viable Product). This lets you test your idea, get feedback, and improve quickly without spending too much time or money upfront.
What Should Your MVP Include?
Here’s what every good MVP for an AI agent should have:
-
Smart Conversation Flow
Your agent should be able to understand basic user input and reply in a helpful, human-like way. Start with simple scripts or prompts and improve them over time. -
Niche-Focused Knowledge Base
Load your agent with facts, data, or content specifically related to your chosen industry. For example, a real estate AI agent might need property laws and pricing trends. -
Relevant, Useful Responses
Don’t try to make your agent answer everything. Just make sure it answers what your niche users actually need. -
User-Friendly Interface
Whether it’s a chatbot on a website or a simple app, keep it clean and easy to use — no complex logins or menus needed. -
Basic Analytics
You’ll want to track how people use your AI agent — what questions they ask, where it gets stuck, and how long they stay. This will help you improve fast.
