Free calculators and unbiased AI tool reviews for bootstrapped founders, marketers, and indie hackers.
I'm Felix Zhu, the founder of Niche AI Tool. I built this site because I was tired of AI tool review blogs that all say the same thing — "ChatGPT is great for writing, Claude is great for coding" — without any real data or testing.
Niche AI Tool takes a different approach. Instead of writing opinions, I build free calculators that solve real problems, and I back up every review with aggregated user data from G2, Capterra, and Trustpilot.
All tools run 100% in your browser. No sign-up, no data collection, no tracking of your business metrics.

15+ free tools including SaaS Revenue, ROAS, CAC, Churn, LTV:CAC, Conversion Rate, and more. All run locally in your browser.
Every review aggregates thousands of real user ratings from G2, Capterra, and Trustpilot. No paid placements, no sponsored rankings.
Side-by-side comparisons of the tools you're actually deciding between — pricing, features, strengths, weaknesses, and who should buy what.
