Frequently asked questions
Does this fixer use AI?
No. It applies a fixed set of mechanical rules in your browser — spacing, capitalisation, repeated words and a small list of word confusions that are only changed when the pattern is unambiguous.
Why are some mistakes not fixed?
Only unambiguous patterns are changed. For example, 'your' and 'you\'re' are only swapped in phrases like 'your welcome', because in most sentences only a reader who understands meaning can tell which is right.
Will it fix my spelling?
No — this tool does not have a spellchecker. It fixes spacing, capitalisation, repeated words and the listed confusions only.
Is my text sent anywhere?
No. Everything runs in your browser and your text never leaves your device.
