Transition Words Checker
Paste your essay or report and see every transition word highlighted by category as you type. Pro Mode adds overuse detection, paragraph coverage analysis, category balance and missing-category suggestions.
Flags sentences with no transition word at the start and offers category-appropriate options — this is pattern-based, not a judgment of your actual argument, so use your own reading to pick the best fit.
Tap any word to insert it at your cursor position in the text box.

Transition Words Checker, Free and Online
A transition words checker scans your writing for connecting words like "however," "therefore" and "for example," highlights each one by category, and shows what percentage of your sentences use one. This one updates live as you type, runs entirely in your browser, and never uploads your text to a server.
Transition words do more work than most writers give them credit for. They tell a reader whether the next sentence is going to agree, disagree, prove a point, or wrap things up, and without them a paragraph can read like a list of disconnected facts even when every individual sentence is well written. This transition words checker online tool highlights every connector it finds across eight standard academic categories, and checks your text against the same 30% coverage benchmark used by Yoast SEO's readability analysis. Pro Mode goes further with overuse detection, paragraph by paragraph coverage, a category balance view, and suggestions for categories your writing hasn't used yet.

2Common Reasons People Check Transition Words
Teachers grading argumentative essays look for transitions like "however" and "therefore" as evidence a student understands how their points relate to each other, not just what the points are. Content writers care for a more practical reason. Yoast SEO's own explanation of the transition words check notes that text without enough connecting words reads as a collection of separate sentences rather than one coherent piece, which is exactly the kind of thing that makes readers bounce off a page early.
3The 8 Transition Word Categories
| Category | Example Words | Purpose |
|---|---|---|
| Addition | also, furthermore, moreover | Add a related point |
| Contrast | however, on the other hand | Signal disagreement or a shift |
| Cause and effect | therefore, as a result | Show a consequence |
| Sequence | first, next, finally | Order steps or events |
| Example | for instance, for example | Illustrate a point |
| Emphasis | indeed, in fact | Underline a key idea |
| Concession | although, granted | Acknowledge a counterpoint |
| Conclusion | in summary, ultimately | Wrap up an argument |
Using a wide spread across these categories tends to matter more than the raw count. A paragraph full of "also" and nothing else still leaves the reader guessing how ideas connect. Writing guidance from Purdue's Online Writing Lab on transitions makes a similar point, framing good transitions as bridges that reference what came before rather than generic connective filler.
4The 30% Benchmark, Where It Comes From
The 30% figure used in this tool's coverage gauge isn't arbitrary. It's the exact threshold Yoast SEO uses in its readability analysis, which is installed on millions of WordPress sites. Yoast's own linguists set the bar at 30% for a green rating, 20 to 30% for an orange rating, and anything under 20% as a red flag, meaning fewer than one in five sentences carries a connecting word. This tool mirrors that green versus orange threshold in a simple pass or fail check, so a score you see here should line up closely with what Yoast would report on the same text.
Every highlight, count, and Pro feature, including overuse detection and paragraph coverage, runs entirely in your browser using JavaScript. Nothing you type is ever sent to a server.
