The Bottom Line

You don't need a budget to start using AI. Every tool on this list has a free tier that genuinely works for small businesses.

The key is to start small: pick one tool, use it for a week, and measure how much time it saves. Then add the next one. Most small businesses find that 3-4 of these tools together eliminate hours of repetitive work per week.
