About ToolPie

ToolPie is a growing collection of fast, free developer tools — formatters, converters, encoders and generators — that run entirely in your browser, with AI built in where it actually helps.

We built ToolPie around one idea: a tool should do its job quickly, respect your data, and get out of the way. There are no sign-ups, no upload steps and no clutter. When you paste data into a ToolPie tool, that data is processed locally on your device and is never sent to a server — the AI features (JSON repair, JSON-to-code generation, natural-language cron) are optional and run only when you choose them.

AI where it counts, plus an API for agents

ToolPie brings AI to the tasks where it earns its place: repairing broken JSON, generating typed code (TypeScript, Java, Python, Go, Rust, C++, C#) from any JSON, and turning plain English into cron expressions — each verified by the deterministic engine so you stay in control. Beyond the web UI, tools are also exposed as a public API and an MCP server, so AI assistants and automation can call the same reliable utilities.
