Our approach

What we care about when building tools

Fast and focused

Each tool does one job well. Pages load quickly, controls are simple and the result is ready to copy.

Explained, not just executed

We write guides for the ideas behind each tool, so you can check results and avoid common mistakes.

Respect for your data

Inputs are used only to produce your result. Google-connected tools request read-only access and nothing more.

Frequently asked questions

Are the tools really free?

Yes. Almost every tool is free and works without an account. The Google Play and AdSense revenue tools are free during their beta period and require Google sign-in because they read your own reports.

What happens to the data I enter?

Your input is used only to generate the result you asked for. We do not keep a member database of tool inputs. See the privacy policy for details on cookies and Google sign-in.

Can I request a new tool?

Please do. Send a short description of the task you want to solve through the contact page. Requests that many people need are built first.

Who writes the guides?

The AIBIZAP team writes every guide while building and testing the tools. If you spot an error or something unclear, let us know and we will update the article.
