Open the toolAbout the free tools
Are these tools really free?
Yes. Every tool on this page runs without an account or a card. You say where the result should go, confirm the address with one click in your inbox, and the check runs: the result shows on the page and lands in that inbox as a copy.
Where does the data come from?
The page checks fetch the live page the way a crawler does. The keyword, ranking and backlink tools read the same search and link index data our paid audits use. Nothing is estimated from a template.
Why do you ask for an email first?
Every check costs us a little, so we run it for a real inbox: you get the result to keep, forward and come back to, and the confirmation stops made-up addresses from burning the daily limits for everyone. One click unsubscribes.
How often can I run a tool?
Each tool has a fair daily limit per visitor so that the free tools stay fast for everyone. Sign up for a free account to run them without limits.
Which tool should I start with?
For a website, the SEO checker. For a keyword, the keyword research tool. For a competitor, the website traffic checker followed by the backlink checker. For your own writing, the word counter and the grammar checker.
Do you keep what I paste?
Text you paste is used to produce the result and kept with the result for as long as the result link works. Fetched pages are cached for a day so repeat checks are instant.
