17 free tools and 73 free guides, plus 3 advanced tools for Amazon, SEO, and social. It all runs in your browser, so nothing is uploaded and no login is needed.
UltraWordCounter began as one writer's fix for a familiar mess: a tab to count words, another to check readability, another for keyword density, and a separate paid app for Amazon or social. Most of them wanted an email first, and many quietly sent your draft to a server to do the work. We built the opposite. One page that does all of it, keeps your text on your own device, and gives away the core for good.
Good writing rarely fails because of the words. It fails because of everything around them: the counting, the checking, the reformatting for each platform, and the constant tab-juggling that eats your afternoon. That busywork is where hours quietly disappear, and it is the part almost no tool handles well in one place.
So we put the whole job on a single page. Count and check as you write, see your keyword density and readability without leaving the tab, and fit the same draft to every platform. Your text stays in your browser the entire time. There is nothing to install and nothing to sign up for before you get value.
The core is not a trial or a teaser. It is the real product, and it stays free.
Word and character counting, grammar and spell check, readability scoring, keyword density, reading time, and more. No account, no limits, no catch.
Word counts, social media, Amazon FBA, and SEO, each paired with a tool built right into the page. Read the guide, then use the tool on the spot.
The Amazon FBA Listing Optimizer, SEO Keyword Density Analyzer, and Social Media Character Tracker are free to use up to 800 words per session.
If your work lives or dies by a limit, a checklist, or a deadline, this was built for you.
Every tool runs on your device. Your text is never uploaded, never stored on our servers, and never sold. There is no account to create, which means there is nothing about you to leak in the first place. Privacy here is not a setting you switch on. It is how the whole thing is built.
The free core replaces a stack of single-purpose tools, and the 73 guides cover the questions people usually pay a subscription to answer. For most writers, that is all they will ever need, and it costs nothing.
If you want unlimited words in the three advanced tools, Pro is $12 a month billed annually (save 37%), or $19 a month, with a 7-day free trial you can cancel anytime. One plan unlocks all three tools, with no add-ons and no per-tool pricing. That works out to about forty cents a day for a workspace that replaces several paid apps. If it saves you one rewrite, one flagged listing, or one post that would have flopped, it has already paid for itself.
Open the tools, read a guide, and see the difference in a few minutes. No login, nothing uploaded, and the core is free for good.
