Writing Analysis, Built In
ProWritingAid-quality writing feedback, right inside Obsidian.
Readability scores, sentence length analysis, passive voice detection, and adverb density — all running locally, instantly, with zero AI costs.
Readability Score
Instant Flesch-Kincaid scoring shows you exactly how readable your writing is. Target the right level for your audience.
Sentence Length
Visual highlighting reveals long, complex sentences that slow readers down. Spot them instantly, fix them in place.
Passive Voice
Passive constructions get flagged automatically. See where your writing loses directness and choose when to rewrite.
Adverb Density
Overused adverbs weaken your prose. Nova highlights them so you can tighten your writing — or let AI do it for you.
See where your writing needs work. Fix it yourself, or let Nova's AI help.

"I built Nova because I was tired of AI tools that generate slop and call it 'assistance.' I wanted something that makes my writing better — not something that writes for me. That's what Nova does."
— Shawn, Nova creator
