Small tools that do one thing
No account, no limits, nothing uploaded. Everything runs in your browser, so you can paste a draft you have not published yet.
Meta tag checker
Paste the source of your page, or just the head section. Nothing is uploaded.
Social share preview
Paste the head section. The preview shows the card, and tells you which tag produced each part of it.
UTM builder
Fill in the destination and the campaign parameters. Copy the link.
robots.txt tester
Paste the file and a URL. The answer comes with the rule that produced it, so you can see why.
Sitemap validator
Paste the sitemap. Everything checkable without fetching the URLs is checked, and nothing is uploaded.
Keyword grouper
Paste a list and it groups them by subject. One cluster is one article.
AI quotability checker
Paste an article and get a score out of 100 for how easily ChatGPT, Perplexity or an AI Overview could lift an answer from it. Nothing is uploaded.
FAQ schema generator
Questions on one line, answers on the next. Copy the script tag and paste it into your page.
hreflang generator
A language code and a URL per line. Copy the tags into the head of every page in the set.
Word counter
Counts as you type. Nothing is sent anywhere, so you can paste a draft you have not published.
Keyword density checker
Shows which words and phrases repeat most, and how often, for single words and for two and three word phrases.
Readability checker
Flesch Reading Ease and grade level, plus the sentences doing the most damage.
Headline analyzer
Length, word balance, and where Google will cut it off. Truncation is by pixel width, not character count, so that is what is measured.
Meta description length checker
Measured in pixels, the way Google truncates, rather than by counting characters.
SERP snippet preview
How your result will look, with truncation measured the way Google does it. Switch between desktop and mobile widths.
URL slug generator
Turns a title into a clean slug. Accents become their base letters, punctuation goes, and you can drop stop words.
llms.txt generator
Builds a valid llms.txt from what your site is and the pages you want models to read first.
These are free because they are useful on their own. If you want the work behind them done continuously rather than by hand, that is what Visorank does.
