Numbered sentences

1. Randozi runs in your browser.
2. Paste any text here!
3. Does it handle questions?
4. Yes, and numbers like 3.14 too.

Sentence boundaries follow the Unicode rules of your browser. They do not know abbreviations such as “Dr.” or “etc.”, so check the list before you rely on it.

How it works

  1. Paste your text and choose its language.
  2. Tick “Treat single line breaks as spaces” if the text was copied from a PDF with hard line breaks.
  3. Read the numbered list, or untick numbering to get one plain sentence per line.
  4. Copy the sentences, or download them as a text file.

Questions

How are the sentences found?
The page uses Intl.Segmenter, the sentence rules built into your browser (the Unicode text segmentation standard). A sentence ends after . ! ? or the full-width 。 ！ ？ and the closing quotes or brackets that follow, and at a paragraph break. A number such as 3.14 is not split. The language you pick can change the result for some scripts.
Does it understand abbreviations like Dr. or etc.?
Not reliably. The Unicode rules cannot know every abbreviation, so a sentence can be cut after “Dr.” or “etc.” when a capital letter follows. Read the list before you rely on it, and join the pieces by hand when needed.
What if my browser has no Intl.Segmenter?
The page falls back to simple rules: a break after . ! ? … when a space or a line break follows, a break right after 。 ！ ？ (with any closing quote or bracket kept in the sentence), and at each line break. The result line under the count says which engine was used. Text with unpaired surrogate characters also uses the simple rules, because the browser function becomes very slow on it.
Is there a size limit, and is my text sent anywhere?
The box holds up to 200,000 characters; a longer paste is cut at that length. The list on screen shows the first 2,000 sentences; the copy and the download always contain all of them. Everything is done by your browser: nothing is uploaded or stored.
