Harper companion

Harper is a free, offline grammar and spelling checker with its own Obsidian plugin. Creative Writer is designed to run alongside it, not instead of it.

The split

Harper edits the sentence. Creative Writer edits the prose.

Harper	Creative Writer
Spelling, grammar, punctuation, agreement, homophones	Passive voice, filter verbs, nominalisations, weak verbs
Intensifiers, hedges, filler ("very", "quite", "just") — boring_words, filler_words, hedging	Clichés, metaphor candidates, repetition
Long sentences (long_sentences)	Sentence rhythm, reading-ease bands, dialogue share
~350 more rules	Adverbs of manner (a craft call, not a grammar one)

Creative Writer once had a "weak words" check for intensifiers and filler; it was removed on purpose because Harper's is better, and having both flag "very" was noise.

On the page

Both plugins decorate the editor. Harper underlines; Creative Writer tints the background, a faint wash for rhythm and a stronger one for a lens's findings. The marks can sit on the same span and stay readable. Neither plugin knows the other is there; there is nothing to configure.
