How to Evaluate AI Tools#

Before adopting any AI tool, ask:

2. What's the time ROI? Hours saved vs cost
3. Does it integrate? Standalone tools create friction
4. Is the output quality good enough? Test before committing

Final Thoughts#

AI tools are not about replacing human creativity and judgment—they're about amplifying it. The best founders use AI to move faster, test more ideas, and focus on what matters: understanding customers and building something they love.

The question isn't whether to use AI tools. The question is which ones to use and how to use them effectively.

Start with the essentials, measure results, and expand from there.
