Count lowercase letters, compare case balance, detect lowercase sentence starts, and produce sentence-case or uppercase output for capitalization cleanup.
Lowercase Letter Counter converts raw pasted text into a clear analytics report. It shows the main count, supporting metrics, density, and an interpretation that helps you decide whether the text needs cleanup or review.
All processing happens locally in the browser. No server upload is required for pasted text.
Example input: this sentence starts lowercase. another line has proper Words and mixed CASE for testing.
Lowercase Letter Counter uses deterministic character matching and script-aware checks where applicable. It also calculates total characters, lines, density, frequency, and category-specific quality signals.
Language detection is heuristic, not a full linguistic classifier. For legal, academic, or production validation, review the exported report manually.
Paste the text and run the tool. It counts a-z letters and calculates the lowercase ratio.
Yes. The case balance score identifies normal, mixed, mostly lowercase, and imbalanced text.
Use Sentence Case or Proper Case output to improve capitalization.
Yes. The output includes lowercase count, uppercase count, letter total, and case distribution.
Use Convert to Uppercase mode to generate an uppercase version of the input.
