Doc Compare

A diff tells you what changed. An improvement score tells you whether the change was worth making. Our AI reads both versions and evaluates the changes against four dimensions: clarity (is the new version easier to understand?), structure (is the hierarchy more logical?), tone (is the register appropriate for the document type?), and completeness (does the new version omit anything critical from the original?).

The result is a score from -10 (strictly worse) to +10 (clearly better), with 0 meaning "different, but neither better nor worse." Our analysis lists the specific improvements and specific regressions separately, so you see exactly what got better and what got worse in the revision.

In contract negotiation, comparing the version you sent with the version that came back is a task lawyers spend hours on. The other party often makes 20-50 small edits, and each one needs to be evaluated for whether it strengthens or weakens your position. Miss a single changed clause and you've potentially signed something you didn't mean to.

Doc Compare is designed for this workflow. Upload your draft as Version A and the counterparty's redline as Version B. The tool shows you every modified clause, every added definition, every removed limitation, and the AI flags which changes materially affect your position versus which are stylistic.

After peer review, you typically get a marked-up version of your paper back from a reviewer or editor. Understanding exactly what they changed, and evaluating whether each change improved the paper, is essential to a productive revision cycle.

Upload your original submission as Version A and the reviewed version as Version B. The diff shows every change, and the AI analysis identifies patterns: "17 changes strengthened passive-voice constructions," "5 changes added hedging language," "3 changes restructured arguments in the Discussion section." This turns a vague 'reviewer feedback' into a concrete list of revision categories.

Here's a non-obvious workflow: after you refine a document through any FixMyDocs workspace, run it through Doc Compare against the original. You'll see exactly what the AI changed, every edit, addition, and removal, with an improvement score telling you whether the refinement was net-positive.

This is how responsible teams adopt AI: not by trusting it blindly, but by auditing its changes. Doc Compare makes that audit trivial.

The line-by-line diff computation happens entirely in your browser, neither document leaves your device for the diff step. Only the text summary (not the full document) is sent to our AI for change analysis, and even that is processed in-memory and permanently discarded. Your document revisions stay as confidential as they need to be.
