Free tools, built by people who use them
Aizen Tools Hub started as a simple idea: business software shouldn't cost a fortune before you've even validated your idea.
We build and curate free calculators, AI generators, and developer utilities for entrepreneurs, freelancers, and small teams — alongside hand-picked products that make running a business easier.
Every tool is free to use, with no account required for most of them. When we do recommend a product, it's because our editorial team has actually vetted it — not because it pays the most commission.
Practical, not gimmicky
Every tool solves a real, everyday problem for founders and professionals.
Built for entrepreneurs
From first-time founders to growing teams — free tools that scale with you.
Always improving
New tools and AI generators ship regularly based on what our users ask for.
Transparent recommendations
Affiliate picks are clearly labeled and only ever hand-selected, never pay-to-play.
