Compares-Text
Every capability of Compares-Text in one place — 12 comparison tools plus AI analysis, all free.
Line-by-line diff with word-level and character-level highlighting. Runs entirely in your browser — your text never leaves your device.
Pixel-level visual diff for PNG, JPG and WebP. Ideal for UI testing, design review and spotting subtle changes.
Extracts full text — including tables, headers and footers — with OCR fallback for scanned PDFs. Pretty-prints JSON for readable diffs.
Separate header and data comparison. Detects changed cells, added/removed rows and column header changes across sheets.
Compares entire directory trees. Finds added, removed and modified files, with per-file diffs on demand.
Git-style diff for 12+ languages (Java, Python, JS, TypeScript, PHP, C#, C++, SQL, Go, Ruby, Rust, Shell) with ignore-comments and ignore-whitespace options.
Compares SQL schemas across MySQL, PostgreSQL, SQL Server and Oracle. Highlights added/removed tables, column, index and foreign-key changes.
Diffs two REST or GraphQL responses — body, headers, status codes and response times side by side.
Compares application, server and nginx logs. Surfaces new errors, new warnings and resolved issues with pattern detection.
Diffs two live URLs — HTML, CSS, SEO tags and metadata. Perfect for migrations, staging-vs-production checks and audits.
Optional AI summary of tone shifts, semantic changes and spelling issues — going beyond simple line diffs.
Step through every change with ↑ ↓ controls in text, document, code, schema, API, log, website, Excel and ZIP comparisons.
Instantly tells you when two inputs are identical with a clear banner — no hunting for differences that aren't there.
