Text
Paste your text. Counts update automatically; case conversion and duplicate removal require an explicit action. Copy the result when ready.
Word & character counter
Count words, Unicode characters and lines; estimate reading time at your chosen speed. Local processing. No account required.
Change text case
Convert uppercase, lowercase or word initials using language-aware rules. Local processing. No account required.
Remove duplicate lines
Keep the first occurrence and original line order; optionally ignore case and surrounding spaces. Local processing. No account required.
Method and limits
Characters are counted as visible Unicode graphemes, including emoji sequences. Words follow browser language segmentation. Reading time is an estimate based on your chosen speed, especially approximate for Japanese and Chinese text. Duplicate removal keeps the first occurrence and the original line order.
