What counts as a filler word?

Filler phrases add length without meaning: "very", "really", "in order to", "due to the fact that", "it should be noted that". Cutting them typically makes sentences 15–25% shorter with no loss of meaning.

What is a good clarity score?

Above 80 is strong. 60–80 is average and typical of published blog content. Below 60 indicates dense passive or filler-heavy writing that would benefit from focused revision.

Writing Clarity Checker: Find Passive Voice, Filler Words, and Weak Sentences

Clear writing converts. Passive voice, overly long sentences, and filler phrases are the three most common patterns that make content feel vague and unconvincing. This clarity checker analyzes every sentence and scores based on the rate of these patterns, not just raw counts. A paragraph that is 100% passive sentences takes the full 30-point passive deduction. Sentences over 30 words are flagged as long, and hedge words like "potentially", "ultimately", "possibly", and "generally" are counted as filler: because they usually are.

For SEO writers, this clarity checker directly surfaces E-E-A-T signals: Google's quality raters specifically look for writing that is "accurate and clear" as part of trustworthiness assessment. For students, passive voice is the most commonly penalized pattern in academic essay writing. This clarity checker provides per-sentence annotations rather than a single global verdict, so you can prioritize the highest-impact edits first.

Content teams run this clarity checker before publishing long-form articles to keep filler word density low. Editors use it to review submitted drafts without manually scanning for passive voice. Non-native English writers use it to flag indirect constructions before peer review. Pair it with the readability checker to measure Flesch Score and grade level, the grammar checker to catch punctuation and syntax errors, and the passive voice remover to auto-rewrite every flagged sentence.

"Most clarity problems in business writing come down to three habits: hiding the actor in passive constructions, softening every claim with a hedge word, and burying the point in a 40-word sentence. Fix those three and your writing becomes noticeably stronger, even if nothing else changes."

Frequently Asked Questions

Passive voice reverses subject and object: "The report was written by the team" instead of "The team wrote the report." It makes writing feel indirect and weaker. Most style guides recommend active voice for clarity and engagement.

Filler phrases add length without meaning: "very", "really", "potentially", "ultimately", "in order to", "due to the fact that". Cutting them typically makes sentences 15–25% shorter with no loss of meaning.

Above 75 is strong and publishable. 55–75 is typical of business blog content — readable but revisable. Below 55 means the writing has serious clarity problems: dense passive voice, heavy hedging, or overlong sentences that obscure the point. Below 30 indicates text that reads as corporate boilerplate or bureaucratic evasion.

Start at 100. Deduct up to 30 points based on the rate of passive sentences (100% passive = full 30 points off). Deduct up to 20 points based on the rate of long sentences (over 30 words). Deduct up to 25 points for filler and hedge words — 3 points per occurrence — plus an additional penalty of up to 15 points when hedge words exceed 4% of total word count. Deduct up to 10 points if average sentence length exceeds 25 words. Because deductions are rate-based, a single 45-word passive sentence full of hedges scores as poorly as it deserves.
