UltraWordCounter is a browser-based writing analysis suite with a free core and optional Pro upgrade. The core word counter is free forever - it counts words, characters, sentences, and paragraphs in real time while analyzing reading grade, passive voice, keyword density, reading time, grammar, spelling, and more.
The core word counter and every utility tool are 100% free with unlimited usage - no account, no login, no time limit, no catch. That is 17 free tools in total, including the word and character counter, grammar and spell checker, readability scorer, keyword density checker, reading and speaking time, case converter, remove extra spaces, diff checker, lorem ipsum generator, words per page, alphabetize, edit counter, random word generator, compare text, auto-capitalize, and a sentence and paragraph counter.
No. UltraWordCounter requires no account, no email, and no login. Open the site and start writing immediately.
Yes. The entire site is fully responsive and works on iOS Safari, Android Chrome, and all modern mobile browsers.
Yes - the 800-word limit is based purely on how many words are currently in the text area. The moment you clear your text or reduce it below 800 words, the tools resume automatically. There is no daily limit, no usage tracking, and no memory of previous usage.
Your text never leaves your browser. All analysis - word counting, grammar checking, SEO analysis, FBA optimization - runs entirely on your device. Nothing is ever transmitted to any server.
As you type, your text is saved to your browser's localStorage - a database built into every modern browser. When you close the tab and reopen it, your text is exactly as you left it. This data stays on your device only and is never accessible to us.
The FBA module tracks Amazon's character limits in real time: Product Title (200 chars), Bullet Points (500 chars each), Product Description (2,000 chars). Progress bars fill and change color as you approach limits. It also checks for commonly banned Amazon words and flags them immediately.
Paste any article, blog post, or page content into the SEO module. It calculates the exact word frequency percentage for every significant word. Results show top 15 keywords ranked by frequency with percentage bars, total and unique word count, Flesch-Kincaid reading grade, and keyword density range.
X/Twitter (280 chars), LinkedIn posts (3,000 chars), Instagram captions (2,200 chars), and TikTok Bio (80 chars). Each shows a real-time color-coded progress bar and over-limit warning.
Reading grade uses the Flesch-Kincaid Grade Level formula: 0.39 × (words ÷ sentences) + 11.8 × (syllables ÷ words) − 15.59. The result is a US school grade level. Most popular web writing targets grade 6–8.
It is a button you drag to your browser's bookmarks bar. Highlight text on any web page, click the bookmark, and UltraWordCounter opens with that text already loaded and counted, no copying and pasting needed.
Yes. You can embed a lightweight version of the counter on your own site with a single line of code, for free, so your visitors can count words without leaving your page.
Yes. You can copy a share link that reloads your text, download a PDF report of your stats, or export the report as a Markdown file. Everything is generated in your browser, with nothing uploaded to a server.
Yes. The Social Media Character Tracker fits your caption to all ten major platforms at once and gives you a ready-to-post version for each, copied in one click, so you write once instead of rewriting for every network.
Yes. The repurpose feature turns a single post into a thread, a carousel outline, a short caption, and a branded quote graphic, so one strong idea can fill several days without starting from scratch.
Yes. You can compare two versions of a post side by side with a quick score on clarity and length, and generate a suggested variant to test against, so you publish the stronger one.
Yes. Pull a strong line from your post into a shareable image in your own brand colors, with the text kept readable on any background. No separate design tool is needed.
Yes. You can plan a month of posts on one calendar, drop queued posts onto specific days, and see the whole month at a glance. Publishing happens in your own scheduler; the tool helps you plan and prepare.
Yes. Each client gets its own workspace with its own queue, content calendar, brand rules, colors, and templates, so nothing bleeds between accounts. You can also send clients a branded plan to review and approve.
Yes. It flags promotional claims, restricted terms, and other compliance triggers in your title, bullets, and description before you publish, so you can fix them before Amazon suppresses the listing.
Yes. A live mobile preview shows where your title truncates on phones, so you can put your most important keywords first, before the cutoff.
Yes. It shows your single and multi-word keyword frequencies as percentages and flags when a term is used too often, so you can avoid the keyword stuffing that gets pages downgraded.
Yes. Alongside keyword density, it gives you a Flesch-Kincaid reading grade and flags passive voice, so your content ends up both optimized and easy to read.
The Pro plan removes all word limits on the three advanced modules (Amazon FBA Optimizer, SEO Keyword Analyzer, Social Media Tracker). All 17 free tools, including the core word counter, grammar checker, and readability scorer, remain completely free forever for everyone - Pro or not.
Yes - both plans include a 7-day free trial. A credit card is required upfront. You can cancel any time before the trial ends and will not be charged.

We offer a 7-day free trial on all Pro plans - no charge until the trial ends. Because of this, we do not offer refunds after the trial period has ended. If you believe you were charged in error, contact us at [email protected] within 7 days of the charge.
