How the convert text to sentence case works

  1. Paste your text.
  2. Each sentence gets exactly one capital letter at its start.
  3. Copy the readable result.

Rules and edge cases

  • The text is lowercased and then capitalised after each sentence-ending . ! or ?
  • Works well on ALL CAPS blocks pasted from PDFs, subtitles and legacy systems.
  • Names, places and the pronoun I need one manual pass afterwards.

Frequently asked questions

What if my text has no punctuation at all?

Only the very first letter is capitalised, because there is no signal for where new sentences begin. Add punctuation first if the text is one long run-on.

Are bullet lists handled?

Each bullet is capitalised only if the previous line ended with sentence punctuation. Lists without full stops keep a single capital at the top.
