Changelog

Paste CREATE TABLE SQL and get an interactive diagram of your database schema with tables, column types, and foreign key relationships rendered visually.

Added a copy button that stays visible even on long documents, and improved error highlighting so the offending line is shown in the gutter.

Match count is now shown inline next to the flag toggles. The test input textarea also remembers its last value between sessions.

Fixed an edge case where generating a QR code with certain Unicode characters caused a blank output. All Unicode input is now correctly encoded.

Side-by-side comparison of major LLM models covering context window size, pricing per million tokens, output strengths, and knowledge cutoff dates.

Build structured LLM prompts with system, user, and assistant sections. Copy the result as plain text or as a JSON messages array ready to paste into an API call.

Translate SQL WHERE clauses into MongoDB filter syntax. Supports equality, inequality, IN lists, LIKE patterns, AND or OR logic, and NULL checks.

Generate SQL INSERT statements from a JSON array. Choose between MySQL, PostgreSQL, SQLite, and SQL Server output formats.

Break SQL queries into clearly labelled clauses so joins, filters, grouping, and ordering are easy to inspect and explain to others.

Large objects now diff up to 10x faster thanks to a smarter structural comparison algorithm. Added a toggle to ignore key order.

Added OKLCH and OKLAB output formats. All values are now selectable individually so you can copy just the channel you need.
