great 2026.5.7

Personal media tracking and ranking via active pairwise/k-way comparison.

A reusable engine for personal media tracking and ranking, inspired by gwern.net/resorter. Rather than asking you to assign absolute scores, Great elicits pairwise or k-way comparisons and infers rankings via the Plackett-Luce model.

The work is split across two repositories. This one is the engine: CLI, library, and static-site renderer. A separate data repo holds your items, comparisons, and consumption log as plain text files in git, and deploys a public ranked-list site to GitHub Pages on push.

Install

uv tool install great

Quick Start

Bootstrap a data repo and try the loop locally:

mkdir my-media && cd my-media
great init                 # seeds one list per kind (movies, tv, ...)
# Edit items/movie.toml to add some items, then:
great rank movies          # interactive Textual session
great consumed "Anora"     # log it (auto-removes from any want queue)
great want "Severance"     # add to want queue
great build                # render → dist/

A working sample lives in examples/sample-data/. great init (default --with-pages) drops a GitHub Actions workflow that builds the site and deploys to Pages on every push.

CLI

great init [PATH] [--list NAME:KIND]... [--with-pages]

Bootstrap a data repo (drops a Pages-deploy workflow by default).
