Comparative Analysis guides.comparative-analysis.hero.title_accent
Put two or more sources to the same question and see exactly where they agree, where they contradict each other, and where the real argument is. The disagreement is the finding.
When to reach for it
When two sources are circling the same subject and you suspect they don't actually agree — two critics on one artist, two catalogues on one movement, a wall text and the scholarship it's drawn from. Where synthesis tabulates and mapping shows proximity, this one goes straight at the tension: it's built to find the fault line, not smooth it over.
Choose the sources and ask a real question
Select at least two materials and give it a specific question to compare them on — "how does each account for the work's relationship to its market?" A sharp question produces a sharp comparison; "compare these" produces mush. The question is the lens, so aim it at the thing you actually want to resolve.
Selecting sources and framing the comparison

A good comparative question names the axis of disagreement you already suspect. You’re asking the tool to confirm, deepen, or overturn a hunch — not to guess what you meant.
See where they diverge
The analysis lays the sources side by side against your question and flags the contradictions directly — not "these differ," but where and how one source's claim collides with another's. This is the material of an original argument: the point two respected voices can't both be right about is usually where you have something to say.

And where they quietly agree
It also surfaces the common ground — the assumptions both sources share, often without either stating them. That shared foundation is easy to miss and important to see: sometimes the most interesting move is to question the thing everyone in the debate has taken for granted.

Take the tension into your writing
You now have the debate mapped: the fault lines, the shared ground, the space your own reading can occupy. Carry it into an essay — this is often exactly what Essay Coaching then helps you build an argument around — or widen the frame with a full synthesis. The comparison isn't the end; it's where your contribution starts.

What it will — and won’t — do
It finds and articulates where your sources agree and disagree on the question you set — the close-reading legwork of a comparison. It won't adjudicate the disagreement: deciding who's right, or that both are wrong, or that the disagreement itself is the subject, is the interpretive work, and it's yours. The tool maps the debate; you enter it.
A comparison costs roughly 4,000 tokens — a few cents to surface a tension that might otherwise take a re-read of both sources to notice.
