Paste your original text, enter the find and replace strings, then press Confirm — everything runs locally and privately. It features live preview: matches are highlighted with the theme color while searching; when replacing, removed text is struck through in red and inserted text is shown in blue, so changes are clear at a glance. Advanced options include ignore case (on by default), match whole words only, and regular expressions (opt-in), covering copy editing, coding, data cleaning and content tidying. The result panel shows the processed text with its character count, ready to copy in one click or download as an image with the brand footer. Every confirm is saved to local history (up to 10 entries) with per-entry copy, per-entry delete and clear-all for easy review. Clean and beautiful UI with light/dark themes and 12 languages — a handy little helper for everyday text work.Text Compare & Diff ToolText Compare & Diff is an intuitive tool that quickly finds the differences between two pieces of text. Paste the original text on the left and the revised text on the right; the tool aligns the lines one by one and computes the longest common subsequence to mark every change precisely: removed content on the left is highlighted in red, added content on the right in blue, and unchanged lines stay as they are. The two panes sit side by side, each taking half the width, with line numbers and character counts always visible, so even long documents are easy to scan for changes. Ideal for code review, copy editing, contract comparison, log analysis and translation checking. Either pane can be copied with one click, and the whole comparison can be downloaded as an image with the site logo for archiving and sharing. Clean and beautiful UI with light/dark themes and 12 languages, fully local and private — a handy little helper for document collaboration and version comparison.Text Repeat ToolText Repeat is a simple and practical text batch generator that helps you output a piece of text repeatedly as many times as you want. Type any content, set the repeat count (5 by default; the tool remembers the count you used last time, so you never need to set it again), then click Confirm to generate the result instantly. The result area shows line numbers and character counts at a glance, making it easy to verify how many copies were generated and the total length. Whether you are creating placeholder text, filling test data, practicing layout, padding copy, or generating repeated paragraphs for website and document testing, one click does it all. The result can be copied with one click, or downloaded as an image together with the site logo for archiving and sharing. Clean and beautiful UI with light/dark themes and 12 languages, fully local and private — an efficient little helper for content creation and batch text processing.Space NormalizerCollapse multiple spaces inside text into exactly N (default 1) and control how many spaces to keep at start and end.Invisible Character Tool — Strip & InjectDetect and strip hidden invisible characters (zero-width space, BOM, soft hyphen, directional marks) from pasted text, or inject them at random positions. One-click copy and PNG download.
