Free AI tools that do the boring math for you

These free AI tools are the calculators, generators and checkers I built for AIDigitalSpace. Each one answers a single question fast: what your AI apps cost, whether automation pays off, which prompt a model reads best.

🔍 How I build these free AI tools

Prices come from each vendor's own pricing page, and the ROI calculator uses U.S. Bureau of Labor Statistics pay data as its default hourly cost. The logic is rule-based, so the same inputs always give the same answer. Some tool pages include affiliate links, which support the site at no extra cost to you and never change a result (disclosure).

FAQ

Do these free AI tools cost anything?

No. All 10 are free, with no account, no trial and no email gate. The only paid product on this page is the Finance Tracker kit, and it's labeled as one.

Do I need to sign up or share personal data?

No signup is needed. The tools run in your browser, and the few that remember things, like saved prompt briefs, keep them in your own browser.

Which tool should I start with?

If you're not sure what you need, start with the AI Tool Finder. If you already pay for two or more AI apps, the Subscription Cost Calculator usually shows a saving or confirms you're fine as you are.

How do you keep the prices and models current?

I recheck vendor pricing pages and model rules when they change, then update the tool's data. Each tool page shows the date it was last updated.
