The three shapes

Mid-sentence it replaces what came before it. On its own it cancels the sentence. And when the whole run was a false start, one phrase throws it away.

It only acts when it is sure

This is the part that matters more than the feature itself. A correction tool that guesses is worse than no correction tool, because you stop trusting the text and start re-reading all of it. When two readings of what you said differ, Lickety changes nothing and tells you so, leaving a decision you can make in a second rather than a silent edit you might never find.

Tidy-up that never rewrites you

Separate from corrections, and worth being precise about, because this is where most tools quietly become a co-author. Lickety capitalises the first word, fixes a stray capital after a pause, collapses a stutter, drops the annotations the recogniser writes over silence, and adds the full stop. It does not reword your sentence, improve your grammar or run your text through a model. Every one of those is its own switch.

Is it on by default?

No. Turn it on in Formatting, under Scratch that. It is off to begin with because a correction feature should be something you chose.

Could it delete something I meant to keep?

It only fires on clear shapes. When two readings differ it changes nothing and says so, rather than picking one and hoping.

Does it rewrite my wording?

No. Tidy-up handles capitals, stutters, spacing and the final full stop. Your words are your words.
