About CountFlows
CountFlows is a free suite of writing tools: counters, converters, and calculators that give you instant answers while you type. There are no accounts, no paywalls, and no uploads. Every tool runs inside your browser, so your text never leaves your device.
Why this site exists
CountFlows started with a simple annoyance: checking a word count online usually meant slow pages, pop-ups, and tools that quietly sent your text to a server. Tools this small should be instant, honest, and private. So I built one that was, then kept going. Every tool since has followed the same three rules: it is free, it works the moment you paste, and your text stays on your device.
Meet the founder
I'm Umair Tufail, a web developer and writer, and the person who builds, tests, and maintains every tool on CountFlows. I also write the guides on the blog, under the same name you see in the article bylines. When a tool here quotes a number, it is backed by published research or documented platform limits, because I rely on these tools for my own writing every day.
Our tools
15 tools are live today, with more on the roadmap:
- Word Counter: Count words, characters, and sentences as you type, with a word goal tracker and a readability score.
- Character Counter: Count characters with and without spaces, plus letters, lines, and paragraphs, against every major platform limit.
- Sentence Counter: Count sentences and check your average sentence length to keep writing readable.
- Syllable Counter: Count syllables in any word, line, or poem, including the 5-7-5 haiku pattern.
- AI Token Counter: Count tokens for ChatGPT, GPT-4, and Claude before you send a prompt, so you never hit a limit or get a surprise bill.
- Reading Time Calculator: Estimate reading and speaking time using research-based averages (238 words per minute for silent reading).
- Case Converter: Convert text to sentence case, Title Case, UPPERCASE, or lowercase without retyping anything.
- AI Text Cleaner: Remove markdown symbols, em dashes, invisible characters, and smart quotes from ChatGPT and AI text in one click.
- Invisible Character Detector: Spot zero-width spaces, non-breaking characters, and other hidden Unicode marks before they damage copy, SEO, or formatting.
- Remove Line Breaks: Strip unwanted line breaks from text pasted out of PDFs and emails instantly.
- Online Text Compare: Compare two pieces of text side by side and highlight the differences.
- Find & Replace Text: Find and replace words, phrases, characters, or multiple values with regex, live preview, and smart conflict checks.
- ChatGPT Watermark Remover: Scan ChatGPT text for hidden Unicode, zero-width characters, unusual spaces, and copy-paste artifacts before cleaning them.
- Keyword Density Checker: Check keyword density by word and phrase, and catch over-optimization before you publish.
- Text Repeater: Repeat a word, phrase, or sentence any number of times, with or without a separator.
What we stand for
- Free, always: no accounts, no premium tiers, no limits on how much text you can check.
- Private by design: all counting happens in your browser. Your text is never sent to our servers, so there is nothing for us to store, read, or share. Details are in our Privacy Policy.
- Instant results: counts update as you type, with no submit button and no waiting.
- Honest numbers: reading speeds, platform limits, and formulas come from published research and official documentation, not guesses.
From the blog
Alongside the tools, I publish research-backed writing guides. A few worth starting with:
- Average Reading Speed: What's Normal and How to Test Yours
- How to Calculate Words Per Minute Reading (Formula + Examples)
- How Long Does It Take to Read 10,000 Words?
- How to Read Faster Without Losing Comprehension
Browse everything on the blog.
Data and accuracy
Our calculators are built on researched formulas and published averages. For example, reading time uses 238 words per minute for silent reading (Brysbaert, 2019). Results are accurate for typical text, but averages are starting points: your own pace and context may vary.
