Matching uses an embedded categorised list of ~75 transition words and phrases. Words like “since”, “still” or “then” also have non-transition meanings, so a few matches may not be true transitions — the 30% guideline is a rule of thumb, not a law.

What is the Transition Word Checker?

Transition Word Checker measures how well your sentences connect. It scans every sentence for transition words and phrases from an embedded categorised list — addition (moreover), contrast (however), cause and effect (therefore), sequence (finally), example (for instance) and conclusion (in summary) — and reports the percentage of sentences that contain at least one.

  • ~75 transition words and phrases in six categories
  • Sentence-percentage score against the 30% guideline
  • Per-category usage counts (addition, contrast, cause, sequence, example, conclusion)
  • Every match highlighted inside its sentence
  • Live updates as you edit
  • 100% offline — nothing is uploaded

About the Transition Word Checker

Transition Word Checker measures how well your sentences connect. It scans every sentence for transition words and phrases from an embedded categorised list — addition (moreover), contrast (however), cause and effect (therefore), sequence (finally), example (for instance) and conclusion (in summary) — and reports the percentage of sentences that contain at least one.

The 30% guideline popularised by SEO readability checks like Yoast is the benchmark: when roughly a third of sentences carry a connector, text feels guided rather than choppy. The per-category counts also reveal habits — many writers lean entirely on contrast words and never signal sequence or conclusion.

Checking happens 100% locally in your browser; your text is never uploaded, and the tool works offline.

Frequently asked questions

What are transition words?

Words and phrases that signal the logical relationship between sentences and ideas: “however” signals contrast, “therefore” consequence, “for example” illustration, “finally” sequence. They act as signposts that tell readers how the next sentence relates to the last.

Where does the 30% guideline come from?

It is the threshold used by popular SEO readability analyses, most famously Yoast's: text scores green when at least 30% of sentences contain a transition word. It is a heuristic for flow, not a grammatical rule — good writing can score lower.

Can I overuse transition words?

Yes. When nearly every sentence opens with “moreover” or “however”, the signposting itself becomes noise. If you score far above 50%, check whether some connectors are doing real logical work or just decorating.

Why did a word get flagged that isn't really a transition?

Words like “since”, “still” and “then” have non-transition meanings too (“since 2019”, “still water”). The tool matches by word list, as all transition checkers do, so a few matches will be incidental — the percentage is best read as an approximation.

Is my text sent to a server?

No. The analysis runs entirely in your browser and works offline. Nothing you paste is stored or transmitted.
