Features

Everything from first draft to final file

One workspace that replaces a diff tool, a writing app, an AI editor, and an export pipeline.

Case-sensitive compare

Catches added, removed, and modified text, plus the case-only changes that other tools silently miss. Built for terminology, units, and legal wording.

AI Writing Studio

Two clean pages side by side. Write on the left; get translation, grammar, impact rewrites, and a writing chat on the right.

Write with AI

Describe a topic and Juxta drafts a chapter or a peer-review-ready paper section by section, flagging where your real data and citations go.

Publishing templates

Eight book layouts and fifteen research formats including IEEE, APA, ACM, and Nature, with a custom cover upload for books.

Publish-ready export

One click to PDF, Word, HTML, Markdown, high-resolution PNG, or vector SVG, styled to your template and saved to your device.

Private and offline

Documents are processed on your machine. Sign in once, then run the desktop app offline with a signed licence.

How it works

Four steps, start to publish

Select a step to see what happens.

Bring in any document

PDF, Word, Markdown, or plain text. Pull in two versions of a paper, a contract, or a manuscript and pin them to Slot A and Slot B.

  • Reads .pdf, .docx, .txt, .md, and more
  • Handles thousands of pages with windowed scanning
  • Nothing uploads; parsing happens in your browser
Your files
Slot ASlot B

Compare, letter by letter

Juxta aligns both versions and marks every difference: added, removed, modified, and case-only edits. Move between changes with a keystroke.

  • Strict case sensitivity
  • Word-level token diff inside each line
  • A clear percent-identical verdict
