Free Online Text Tools for Writers, Students and Developers

Text manipulation is a daily task for writers, students, content creators and developers alike. Whether you need to count words before submitting an assignment, check whether an article is readable for your target audience, compare two versions of a document or convert text to a URL-safe slug, there's a tool for each of these tasks — and they're all free.

Here are 12 free online text tools on Nutilz, organized by use case.

Writing & Analysis

Word Counter — Counts words, characters (with and without spaces), sentences, paragraphs and estimated reading time. Updates live as you type. Useful for essays, blog posts, social media copy and SEO meta descriptions with character limits.

Readability Checker — Scores text using the Flesch Reading Ease, Flesch-Kincaid Grade Level and Gunning Fog Index. A Flesch score above 60 is considered readable for a general audience. Paste an article draft to see whether it matches your target reading level.

Word Frequency Counter — Analyzes text and ranks every word by how often it appears. Supports stop word filtering to remove common words (the, a, in) and reveal the content words that define your text's topic. Useful for SEO keyword density checks and understanding writing patterns.

Formatting & Conversion

Text Case Converter — Converts text between UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case and kebab-case with one click.

Slug Generator — Converts a heading or title to a URL-safe slug (e.g. "My Blog Post Title" → "my-blog-post-title"). Also converts to snake_case, camelCase and PascalCase.

Text Cleaner — Removes extra whitespace, line breaks, HTML tags and special characters from pasted text. Useful for cleaning up text copied from PDFs, Word documents or web pages.

Text Sorter — Sorts lines alphabetically (A→Z or Z→A), by length, or randomly. Also removes duplicate lines and empty lines.

Comparison & Finding

Diff Checker — Compares two pieces of text and highlights exactly what changed — additions in green, deletions in red. Useful for comparing document revisions, code snippets and configuration files.

Find & Replace — Find text and replace it with something else, with support for regex patterns, case sensitivity and whole-word matching. Useful for batch editing without opening a code editor.

Placeholder & Reference

Lorem Ipsum Generator — Generates placeholder Latin text by paragraphs, sentences or words. Used in design mockups, UI prototypes and layout testing when real content isn't ready yet.

Markdown Preview — Write Markdown on the left and see the rendered HTML output on the right in real time. Supports headings, bold, italic, code blocks, tables and links.

Morse Code Translator — Translates text to Morse code (dots and dashes) and back, with optional audio playback so you can actually hear the encoded message.
