Text and writing tools
A word limit, a messy list and two versions of a draft need different tools. Start with Word Counter for a length check, Character Counter for a form limit, or Text Diff to see what changed between revisions. For copied text, the space and line-break tools clean up formatting without requiring a document editor. These tools accept pasted text and work on your device, so you can edit a draft without sending its contents to a processing service.
Choose a converter by the result you need. Case Converter changes capitalization in prose; camel, snake and kebab case converters prepare identifiers. Remove Duplicate Lines is useful for repeated entries, while sorting tools reorder a list. Check whether a cleanup option ignores letter case or trims spaces before applying it, because two lines that look similar can carry different information.
Counting conventions also matter. A character count can differ from the limit shown by an app that counts bytes or UTF-16 units. Readability and syllable estimates are calibrated for English and are useful as editing prompts. They cannot judge whether an argument is correct or a sentence makes sense. Keep the original text until you have checked the result.
