Sentence Opener Analyzer

See how every sentence in your draft begins. Groups openers by first word and by pattern, and flags runs of consecutive sentences that start the same way.

Paste at least one sentence to see the opener breakdown.

Patterns are matched from hand-written word lists, so a word that can be several parts of speech ( “after”, “that”) is bucketed by its most common sentence-initial use. The counts are the point — 0 sentences with three openers is a rhythm problem however you label it.

What is the Sentence Opener Analyzer?

Repetitive sentence openings are one of the easiest problems to fix and one of the hardest to see in your own draft.

  • Every sentence grouped by its opening word, with repeat counts
  • Eight opener patterns including dialogue and -ing participles
  • Configurable run length for flagging consecutive repeats
  • Percentage bars showing the balance of opener types
  • Full sentence list with flagged runs highlighted in place
  • Processed entirely in your browser — nothing is uploaded

How to use the Sentence Opener Analyzer

  1. 1

    Paste a chapter, scene or article into the input box.

  2. 2

    Set how many consecutive sentences count as a repetitive run — three is a good default.

  3. 3

    Read the pattern table to see the balance of articles, pronouns, participles and prepositions.

  4. 4

    Scan the frequency chips: red words open three or more sentences, amber words open two.

  5. 5

    Work through the highlighted sentences in the list and rewrite the flagged openings.

About the Sentence Opener Analyzer

Repetitive sentence openings are one of the easiest problems to fix and one of the hardest to see in your own draft. Five sentences in a row starting with “She” or “The” reads as monotonous long before a reader can say why. This analyzer splits your text into sentences, groups them by their first word and by opener type, and flags every run where the same pattern repeats.

Each sentence is classified as starting with an article, a pronoun, a conjunction, an -ing participle, a prepositional phrase, an -ly adverb, dialogue, or a plain subject. The pattern table shows the mix at a glance, the frequency chips show which exact words you lean on, and the sentence list highlights every sentence caught in a flagged run so you know where to edit.

Everything is analysed locally in your browser — your manuscript is never uploaded, nothing is stored, and the tool keeps working offline once the page has loaded.

Frequently asked questions

How many sentences should start the same way?

There is no hard rule, but two in a row is usually invisible and three starts to be felt as a rhythm. If a single word opens more than about 15% of your sentences, it will read as a tic even if no two are adjacent.

Why do so many of my sentences start with a pronoun?

Close third-person and first-person narration naturally lean on “I”, “he” and “she” because the viewpoint character drives every action. The fix is usually not fewer pronouns but more varied structures — start some sentences with the object, a clause, or a piece of dialogue.

What counts as an -ing participle opener?

A sentence beginning with a present participle, as in “Walking to the door, she stopped.” They are useful in small doses but stack up quickly, and several in a row make everything feel simultaneous when it should be sequential.

How does it decide which pattern a sentence uses?

It matches the first word against hand-written lists of articles, pronouns, conjunctions and prepositions, then falls back on suffix rules for -ing and -ly. Words that can be several parts of speech are bucketed by their most common sentence-initial use.

Does it work on dialogue-heavy fiction?

Yes. Sentences that open with a quotation mark, a guillemet or an em-dash are classified as dialogue openers and counted separately, so a scene of pure conversation is not reported as one long run of repeated words.
