Watch Smart Revision in Action
See Smart Revision constrain an AI edit, compare its impact, and apply only the changes you approve.
Watch Nova preserve constraints, show meaning risk and before/after impact, review two low-risk edits, and apply only accepted changes.
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 category filters, issue cards, Jump, note-local Ignore, and safe Apply actions when a direct replacement is available. 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 flagging 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 for safe direct replacements.
Clarity, Not Grammar
Prose Linter flags very hard sentences, hard sentences, repeated words and phrases, passive voice, weakeners, and complex words.
Jump, Apply, Ignore
Jump moves the editor to the issue and highlights the relevant text. Ignore hides a specific issue for the current note, and Apply appears only for safe direct replacements.
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.
Edit Without Leaving Obsidian
Nova works on the text you have already written, so you can stay in your note.

Why Nova Fits Obsidian
Direct AI editing and local writing analysis in one plugin.
Privacy-First Design
Use local AI through Ollama or LM Studio, or connect directly to Claude, OpenAI, or Gemini with your own API key. Nova does not collect plugin telemetry.
Context From Your Vault
Nova can use notes you link as context, so you do not have to repeat the same background every time.
Editor, Not Generator
Nova improves the words you wrote without taking over the draft. Local tools also check readability, passive voice, and other style signals.

"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 without writing for me. That's what Nova does."
