Free tools for everyday writing and SEO work
AllSEOToolkit is a growing set of free online tools for anyone who works with text: writers and editors, students, bloggers, marketers, developers and SEO specialists. Each tool does one job well and shows the result as soon as you paste your text. There is nothing to install, no account to create and no limit on how often you use them.
Your text stays on your device
The tools run inside your web browser, so the text you paste is processed on your own computer or phone. It isn't uploaded to a server, saved or shared. That makes AllSEOToolkit safe for unpublished drafts, client copy, assignments and anything else you would rather keep private. Once a page has loaded, its tool keeps working even if your connection drops.
What you can do here
Count and measure. The Word Counter and Character Counter track length as you type, with goals and limits for essays, meta descriptions and social posts. The Reading Time and Speaking Time calculators turn word counts into minutes.
Fix and convert. The Case Converter switches text between 12 cases, the Text Cleaner strips formatting and junk characters from copied text, and Remove Duplicate Lines and Sort Lines tidy up lists in seconds.
Compare and analyse. The Text Diff Checker highlights every change between two versions of a document, and the Keyword Density Checker and Word Frequency Counter show which words and phrases a page leans on most.
Accurate, and clear about how
Every tool page explains exactly how its results are worked out, with examples and answers to common questions. When other programs might give a slightly different number, we tell you why, so you always know what you're looking at.
