The Writing Analyzer reads the document you have open and tells you how it is likely to land with a reader. It covers three separate things.

Readability and length

Standard measures of how hard the writing is to read, including a readability score and an approximate grade level, alongside word and sentence counts. Useful when you have a target: a script that has to run to time, a page that has to be readable by a general audience.

Sentence-level issues

Rather than one score for the whole document, it flags specific sentences worth another look and explains why. Each issue can be shown or hidden individually, and you can toggle the highlighting on and off so the document is readable while you work through them.

This is the part that actually changes the writing. A single readability number tells you something is wrong; the flagged sentence tells you where.

How AI-generated it reads

The analyzer also estimates whether the text reads as machine-written, from Likely to be AI-generated through Likely human-written to Very likely human-written.

This matters if you draft with AI and publish under your own name. It is a signal about how the prose reads, not a verdict on how it was made: heavily edited AI drafts often read as human, and some genuinely human writing reads as machine-made because it is uniform and hedged.

Tips and tricks

Run it after drafting, not during. Writing to satisfy a score produces careful, flat prose. Draft the thing, then analyse it.

Fix the flagged sentences, then re-run. The sentence issues are the actionable part. Rewriting three or four flagged sentences usually moves the overall scores more than a broad pass over everything.

Use it on AI-assisted drafts specifically. If you asked the assistant for a first draft, this is the fastest way to find the passages that still sound generated so you can put your own voice through them.

Watch the grade level against your audience. A lower grade level is not automatically better. Match it to who is reading: a technical brief and a landing page should not score the same.

Good to know

The analyzer looks at the document currently open and reflects your latest edits, so re-running after changes shows the effect immediately.
