Which text tool?
One line each: the situation the tool is the answer to.
| Tool | Best when |
|---|---|
| Case Converter | The casing is wrong — Title Case, snake_case, camelCase or SHOUTING. |
| Line Sorter & Deduplicator | A list needs sorting, de-duplicating or the blank lines removed. |
| Online Diff Checker | Two versions of a text and you need to see exactly what changed. |
| Word & Character Counter | A limit to hit — words, characters, reading time. |
| Text Summarizer | A long passage and only the key sentences are needed. |
| Invisible Character Detector | Text that looks right but behaves wrong: invisible or look-alike characters. |
| Fancy Font Generator | Styled Unicode text for a bio or a post where formatting is not allowed. |
| Text Translator | A quick translation without a service seeing the text. |
| Time-Locked Message | A message that must stay unreadable until a set moment: a prediction, a sealed bid, a note for a birthday. |
About these text tools
Text work looks trivial and is full of definitional edges: whether 'Apple' and 'apple' are the same entry, whether item10 sorts before item2, whether a hyphenated compound is one word or two. Different tools answer these differently, which is why two word counts rarely agree and why a dedupe can miss lines that differ by an invisible trailing space. These tools surface those choices as options rather than making them silently.
Because every operation here is a pure transformation, nothing needs to leave your machine — which matters more than it first appears, since the text people clean and compare is so often the sensitive kind: contracts, customer lists, config files, drafts. Paste, transform, copy, and the content was never anywhere but your tab.
