Frequently Asked Questions about AI Tools

What is the best AI tool for founders?

For most founders, Claude or ChatGPT covers 80% of use cases โ€” writing, strategy, and coding assistance. Cursor is the top pick if you're writing code daily.

Are AI tools worth it for small startups?

Absolutely. AI tools let a team of 1-2 people operate like a team of 10. The time savings on writing, research, and coding alone justify the cost.

What's the best free AI tool?

ChatGPT (free tier), Claude (free tier), and Perplexity (free tier) are all excellent starting points with no cost.

How do I choose between Claude and ChatGPT?

Claude tends to be better for long documents, nuanced analysis, and writing that sounds human. ChatGPT has more plugins and integrations. Try both โ€” both have free tiers.
