Artificial intelligence is no longer reserved for tech giants. In 2026, integrating AI features into your website has become accessible to all businesses. Here's a complete guide to get started.

Different Types of AI Integration
1. Chatbots and Virtual Assistants
Modern AI chatbots (like those based on GPT-4 or Claude) can handle 70%+ of customer queries automatically. They offer a fluid and natural experience, far from the basic bots of a few years ago.
Use cases:
2. Personalized Recommendations
AI can analyze your users' behavior to suggest relevant content or products.
Example: An e-commerce site can increase its conversion rate by 15-30% thanks to personalized AI recommendations.
3. Real-Time Data Analysis
Detect trends, anomalies, and opportunities through automatic data analysis. AI can identify patterns invisible to the naked eye.
How to Choose the Right Solution?
Here are the 3 questions to ask yourself:
1. Define your objectives: Customer support? Personalization? Automation?
2. Evaluate your data: Do you have enough data to train a model?
3. Choose between build vs buy: Existing APIs (OpenAI, Claude) vs custom solution.
