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.

Start Writing Better
Join writers who use AI to edit — not to generate.
"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
