Lixity

Read before you revise.

Lixity is a local manuscript analysis tool for authors, editors and researchers. Read continuous chapters, inspect changes in sentence rhythm, vocabulary, dialogue and tense, and keep research beside the text. Measurements help you choose passages to review; they do not grade literary quality or rewrite prose. The browser app, CLI and Python API share one analysis pipeline.

The demo opens The Crate at Warehouse 4: six invented English chapters and a research archive with credited historical images. Explore the three native workspace views without an account or upload. It is read-only: local actions cannot import, edit or save. Follow the three-minute walkthrough or browse more views and image credits.

Install and start

Install uv, then run on Windows, macOS or Linux:

uv tool install --python 3.12 --managed-python lixity
uv tool update-shell

Open a new terminal:

lixity --version
lixity service start --open

Choose Open Project or Analyze a manuscript, then confirm the language. English is the default; automatic detection is explicit. Built-in analysis runs on your computer. Optional integrations have separate data boundaries.

Your first project explains the workflow. Installation and updates covers launchers, pinned wheels, service management and removal. After upgrading, run lixity service restart --open and reload the browser; installing a package does not update an already running service.

What you can do

• Read and review. Adjust the reading view, turn Analysis on or off, and open passage Values or work markers when needed. Compare chapters against your manuscript’s own patterns, then return to the text.
• Connect research. Keep a dossier alongside a passage. The experimental research workspace connects retained sources, authored claims and decisions to exact manuscript quotations. Zotero remains your collection tool; retaining evidence is an explicit action. An integrity check is not a fact check.
• Export and automate. Create editorial, reading, submission or analysis PDFs; use terminal reports and versioned JSON in your own workflows. lixity --help and lixity about --json describe the installed commands and capabilities.

English and German have the broadest analysis resources. French, Spanish, Italian, Portuguese and Dutch offer localized interfaces with narrower heuristic coverage. Language support and interpretation explain coverage, short-sample limits and unavailable measurements.
