Small utilities for the everyday work around AI systems: inspecting API payloads, cleaning up config, checking model output. Everything runs in your browser, and nothing is sent to a server.
Data
Format, validate, and minify JSON in your browser. Paste it, upload a file, or load it from a URL. Errors show the exact line and column.
Open tool →C# / .NET
Paste JSON and get C# model classes or records, ready for System.Text.Json or Newtonsoft.Json. Nested objects, arrays, nullable types, dates, and GUIDs are inferred for you.
Open tool →SQL
Format and beautify SQL queries for SQL Server (T-SQL), PostgreSQL, MySQL, Oracle, and more. Set the indentation, keyword case, and layout, and get the exact line of any syntax error.
Open tool →Images
Preview SVG code live and safely, check its size and viewBox, fix common errors, and export it as PNG, a data URI, a CSS background, or an <img> tag.
Open tool →Text
Compare two texts or code files side by side, with changed words highlighted. Ignore whitespace or case, and export a unified .diff patch that git apply accepts.
Open tool →Images
Create QR codes for links, Wi-Fi logins, email, phone, and SMS. Set error correction and colors, then download a crisp SVG or PNG. Static codes, no tracking, no sign-up.
