Writing Style Checker (Hard Sentences, Adverbs, Clichés)
Check English writing for hard-to-read sentences, adverbs, passive voice, clichés, wordy phrases with simpler alternatives, filler words and punctuation slips.
These are rules of thumb, not grammar rules: a passive sentence, an adverb or a long sentence is sometimes the right choice. The checks are for English text.
| Sentence | Level | Grade | Words | Text |
|---|---|---|---|---|
| 2 | Very hard | 23 | 37 | It is very important that every team utilizes the shared calendar in order to avoid conflicts that have historically been extremely difficult to resolve beca… |
| Type | Found | Suggestion | Sentence |
|---|---|---|---|
| Wordy | facilitate | Try: help, ease | 1 |
| Cliché | At the end of the day | Say it in your own plain words | 1 |
| Passive | was designed | Say who does it, with an active verb | 1 |
| Adverb | historically | Cut it, or use a stronger verb or adjective | 2 |
| Wordy | utilizes | Try: use | 2 |
| Wordy | in order to | Try: to | 2 |
| Filler | very | Often unnecessary; remove it or be specific | 2 |
| Filler | extremely | Often unnecessary; remove it or be specific | 2 |
| Passive | been scheduled | Say who does it, with an active verb | 2 |
| Adverb | smoothly | Cut it, or use a stronger verb or adjective | 3 |
| Repetition | 3 sentences in a row start with “the” | Vary how sentences begin | 3 |
| Punctuation | Double space: “··” | Use one space | 4 |
| Punctuation | Repeated punctuation: “!!” | Use one mark, or … for a pause | 5 |
Paste an English draft and see what makes it harder to read than it needs to be: long, complex sentences, -ly adverbs, passive voice, wordy phrases that have a plainer equivalent, filler words, clichés, runs of sentences that start the same way, and small slips such as double spaces, “the the” or unclosed brackets. Every finding is listed with the sentence it is in and a suggestion. The checks are fixed rules running in your browser, so the same text always gives the same report.
How to use this tool
- Paste your text.
- Leave all checks on, or untick the ones you do not care about.
- Read the totals, then work through the “Hard to read sentences” and “Issues” tables in order.
- Edit your draft and paste it again to see the counts drop.
Formula
Sentence grade (ARI) = 4.71 × letters ÷ words + 0.5 × words − 21.43
The Automated Readability Index is applied to each sentence of 8 or more words: a grade of 10 to 13.9 is marked hard and 14 or more very hard. The whole-text grade uses words per sentence instead. Passive voice is a form of “be” followed by a past participle (an -ed word or one of about 100 irregular ones), optionally with one adverb in between, as in “was quickly approved”. Adverbs are -ly words minus about 110 that are not adverbs (family, early, likely, July).
Example
The sample text has 5 sentences and the report finds 14 issues. The second sentence (37 words, ARI grade 23) is very hard. The tables also list the cliché “At the end of the day”, the wordy “facilitate”, “utilizes” and “in order to”, the fillers “very” and “extremely”, the adverbs “historically” and “smoothly”, the passives “was designed” and “been scheduled”, three sentences in a row that start with “The”, a double space and “!!”.
Frequently asked questions
Is this like the Hemingway app?
It checks similar things, such as hard sentences, adverbs and passive voice, with openly stated rules. It is not affiliated with Hemingway, and its thresholds are its own, so the counts will not match that app exactly.
Should I remove every adverb and passive sentence?
No. Use the counts as a prompt. A passive sentence is right when the doer is unknown or unimportant (“the patient was discharged”), and some adverbs carry meaning. Aim for fewer, not none.
Does it check grammar and spelling?
Only a few typo patterns: repeated words, doubled punctuation, missing spaces and unmatched brackets or quotes. Use a spell checker for spelling.
