A Text Toolbox That Lives on Your Phone

Stop juggling browser tabs and websites for things you do every day. TextLab puts all the common text tools in one fast, beautiful app.

Arrange Mode

Reorder lines, paragraphs, or sentences by dragging - or split on a custom delimiter. Sort, reverse, dedupe, shuffle, and trim, with formatting kept intact.

Case Conversion

Upper, lower, title, sentence, snake_case, kebab-case, camelCase, PascalCase, and constant case in one tap.

Undo & Redo

Full multi-step undo and redo across every change - typing, transformations, and rearrangements. Command-Z on Mac, buttons on iPhone and iPad.

JSON Formatter

Pretty-print, minify, validate, and explore JSON with collapsible nodes and syntax highlighting.

Markdown Preview

Live Markdown preview with GitHub-flavored extensions, code blocks, and tables.

Text Cleaner

Remove extra whitespace, blank lines, smart quotes, soft hyphens, zero-width characters, and BOMs.

Encoders & Decoders

Base64, URL, HTML entities, hex, binary, JWT decode, and slug-safe encoding.

Regex Tester

Live regex highlighting with named groups, replace mode, and a built-in cheat sheet.

Side-by-side and unified diff for any two text snippets.

AI Text Actions
