Free Text Compare Tool, Duplicate File Finder and Seven Everyday Tools

Paste the first version on the left and the changed version on the right. ToolForge lines the two texts up, finds the shortest set of lines that were removed and added, and pairs a removed line with an added one when the two are alike, so a line that was edited shows as one changed line with the changed words (or letters) marked. Long runs of lines that did not change fold away, and Next change jumps from one difference to the next.

Yes. Tick Ignore capital letters to treat "Hello" and "hello" as the same, and Ignore spaces to treat lines that differ only in spaces, tabs or the spaces at their ends as the same. The summary then says that the texts are the same apart from those. Copy as patch gives the differences as a standard patch file, the kind tools such as git read.

Notes save as you type. A line that starts with - [ ] is a checklist item you can tick in the preview, #word tags a note, # at the start of a line makes a heading, and **bold**, *italic* and links work too. Notes sit in folders, can be pinned to the top and searched, and a deleted note stays in Trash for 30 days. Download all saves every note as a Markdown file in a .zip, in one file, or as a backup you can import later.

It lists every file in the folder you choose and its sub-folders. Files of the same size are then compared by a SHA-256 fingerprint of their whole content, so exact copies are found whatever their names. Copies by name are files such as report (1).pdf or report - Copy.pdf next to report.pdf whose content differs, often an older or newer version. Look-alike photos, if you tick them, are found by a small fingerprint of each picture, so the same photo saved again, resized or lightly edited shows up as well.

Nothing in the folder changes until you choose. In each group one file is kept and, for exact copies, the others are ticked; copies by name and look-alike photos start unticked, since they may be different versions. Move to a Duplicates folder puts the ticked files into a folder named _Duplicates inside the one you checked, so you can look through them before deleting anything yourself. Delete removes them for good, not to the Recycle Bin, and asks first. Changing the folder from the page works in Chrome and Edge on a computer; other browsers get a script that lists the files and changes nothing until you type YES.

Your text passes through steps you choose, from top to bottom: trimming and fixing spaces, removing empty or repeated lines, sorting, joining or splitting lines, numbering, find and replace with or without a pattern, removing HTML tags or links, straightening quotes and dashes, changing case and more. Each step says what it changed, the hidden characters view shows non-breaking spaces and invisible characters, and a set of steps can be saved as a recipe.

Type or paste text and press Keep, press Ctrl V on the Clipboard screen, or copy something in one of the other tools: it is kept in the list, newest first, and one click copies it back. Write {{name}} in a clip to be asked for a name each time you copy it. If you tick Keep what I copy in other apps, the browser asks once for permission to read the clipboard, and what you copied elsewhere is kept each time you come back to this tab. Pictures are kept in this browser as well.

Table to CSV reads a table you copy from a web page or a document: merged cells are spread over the cells they cover, header rows that sit on top of each other are joined, and links can be kept as columns of their own. JSON to Excel turns a JSON file into a spreadsheet: you choose which list becomes the rows, nested data is laid out in columns or sheets, and an Excel file can be turned back into JSON.

Browsers let a page open one new tab per click unless you allow pop-ups for that page, so the first press may open one tab and ToolForge tells you how many were stopped. Allow pop-ups for this page from the icon at the right end of the address bar, choose to open 5, 10 or 20 per click, or use Open next, which opens one link per click and always works.

No. The files are read by your browser on this device, and their names and contents are not sent anywhere. Everything you paste, type or open is read and compared by your browser too. Your notes, clips, recipes, sets of links and the text in the boxes are kept only in this browser, and Delete everything in the Settings window removes them. A backup is a file you download and keep yourself.

Each side of Compare can hold up to 2,000,000 characters and 200,000 lines. A note can hold up to 200,000 characters, and up to 2,000 notes and 1,500,000 characters of notes are kept in all. The clipboard list keeps up to 1,000 clips (300 unless you change it). These limits leave room for the other tools on this site, which share the same browser storage.

TextForge's Compare two texts compares the numbers of two texts, such as their word counts and readability, while ToolForge compares their lines and words. StickyBoard is a board of sticky cards, while Notes is a list of notes with folders, tags and checklists. TextForge changes the case of a text and cleans its spacing, lines and repeats in one go; Clean text runs the steps you choose in order and shows what each one changed and what is hiding in the text. DataForge and CodeForge convert whole files between formats such as CSV, Excel, JSON and XML; here Table to CSV reads a table copied from a web page with its merged cells, JSON to Excel lets you choose which list becomes the rows and lays nested data out in columns or sheets, and Text to table lets you edit and sort a table before saving it. Nothing else on the site finds duplicate files, opens many links at once or keeps a clipboard list.
