Watch Nova in Action
See Prose Linter review an Obsidian note with local highlights and issue cards
Watch Nova flag clarity issues in place, then review them from the right-side Prose Linter pane.
Sharper Prose, Native to Obsidian
Prose Linter is a free, local clarity workbench for Obsidian notes.
Open the right-side Prose Linter pane. Nova adds filled, category-colored highlights directly in the active note while the pane is active, then gives you filters, issue cards, Jump, Ignore, and safe Apply actions. It works offline, understands Markdown, and needs no account, API key, upload, or Supernova license.
# Essay Draft
The introduction tries to explain the whole argument, define the stakes, summarize the evidence, and preview the conclusion in one breath.
Nova keeps your voice while removing very soft wording.
The result reads cleaner because the result is easier to scan.
Split the setup from the conclusion.
47 words. Too many ideas are competing for attention.
Suggestion: break it after the setup.Use "show" instead of "demonstrate" when the meaning is unchanged.
"very clear" can become "clear".
Apply appears only when Nova verifies the exact current text.
Clarity, Not Grammar
Prose Linter flags very hard sentences, hard sentences, repeated words and phrases, passive voice, weakeners, and complex words.
Jump, Apply, Ignore
Every issue can jump to its location. Safe local replacements appear only when Nova can verify the exact current text still matches.
Markdown-Aware Review
Nova avoids noisy warnings in frontmatter, code, tables, links, tags, block IDs, and Smart Fill markers so review stays focused on prose.
Metrics Stay Responsive
Writing Analysis now analyzes the current note as a snapshot, marks edits stale, and refreshes when you click Analyze.
Writing Analysis is metrics-first. Prose Linter owns editor highlights and issue-by-issue review.

AI editing and deterministic writing analysis — one plugin, zero compromises.
Privacy-First Design
Use local AI (Ollama, LM Studio) or connect Claude, OpenAI, or Gemini with your own API keys. No middleman, no data collection.

Nova automatically pulls in your linked notes as context. No re-explaining what you've already written elsewhere. Your knowledge graph becomes your AI's knowledge too.
Editor, Not Generator

Use Ollama or LM Studio — your documents never leave your computer. Perfect for sensitive work, confidential research, or personal writing.

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
