Attune · audience checks for writers
Write for the reader in front of you.
Attune checks every paragraph against the person you're writing for. It shows which ones fit, which ones drift, and the smallest change that would fix them.

Examples:
Deep review reads a paragraph the way a writing teacher would.
It checks the paragraph against your reader and a 10-part rubric, quotes your exact words, and suggests the smallest fix that keeps your meaning. It also tells you when it needs more context.
Deep review runs inside the Attune extension and add-ons, using your own Anthropic API key.

How it works
Three steps, while you write
Attune follows the order writing teachers recommend: define the reader first, then judge the writing against them.
1
Describe your reader
Who they are, what they already know, what they need from you. Pick a preset or write your own.
2
Scan your writing
Attune reads each paragraph and colors it: green fits, yellow drifts, pink loses your reader.
3
Fix what needs work
Go to each paragraph in order. Swap jargon in one click, edit, and re-check.
What it checks
Four questions for every paragraph
Each answer is a plain-language label and a short fix, not a reading-level number.
Audience fit
Will this reader understand it and care? Checks background knowledge, jargon and tone.
Your reader: Likely lost“leverage my skill set to optimize workflow efficiencies”
Focus
Does the paragraph make one point, and does it serve your main idea?
Partly focusedUnclear how this supports your main point.
Voice
Does it sound like the same writer as the rest of the piece?
Voice shiftChattier than the rest of the piece.
Clarity
Could anyone follow it? Flags tangled sentences and repetition.
Anyone: Easy to followSentences vary in length and read cleanly.
Grounded in research
A rubric built from writing-center guidance
Deep review follows a written rubric drawn from public guidance on audience, paragraphs and plain language. It quotes your exact words and says when it doesn't have enough context.

FAQ
Questions
Is Attune an AI detector?
No. Attune doesn't guess who wrote something. It checks whether the writing works for the person who'll read it.
Is my writing stored or sent anywhere?
The scan on this page runs entirely in your browser. Deep review, in the extension, sends only the paragraph you choose, with its neighbors and your reader description, to Anthropic's API using your own key.
Are the scores grades?
No. They're estimates to help you revise. A score of 83 and a score of 85 aren't meaningfully different. Read the labels and the fixes, and trust your own judgment.
Does it penalize technical words or informal English?
Not on their own. Technical terms are fine when your reader knows them, and Attune doesn't treat one style of English as the correct one. It flags words only when your reader is likely to get lost.
What does it cost?
The scan is free. Deep review uses your own Anthropic API key and costs a few cents per paragraph.
