About AI Data Inspector

AI Data Inspector is a collection of free, privacy-first developer tools for working with data and AI.

Every tool runs entirely in your browser. No uploads, no servers, no tracking. Your data never leaves your device.

We built this because existing tools often require uploading sensitive data to unknown servers. With AI Data Inspector, you can format JSON, test regex patterns, analyze CSV data, and compare AI prompts — all locally.

Why "AI Data Inspector"?

As AI tools become mainstream, developers need better utilities for working with AI outputs — comparing prompts, inspecting JSON responses, analyzing data. We're building the tools we wished existed.

Open Source

Our tools are built with open-source technologies: Astro, React, and Tailwind CSS. We believe in transparency.
