# Bias Sorter

> Bias Sorter is a web app for creating, sharing, browsing, and using visual one-on-one ranking sorters.

Bias Sorter lets users build image-based preference sorters, run head-to-head comparisons, view final rankings, and download result images. Public sorter templates are discoverable after admin review. Private, pending review, and rejected sorters may be accessible by direct URL but are not intended for public discovery or indexing.

## Core Pages

- [Home](https://biassort.com/): Overview and featured public sorters.
- [Browse sorters](https://biassort.com/browser): Public sorter discovery.
- [Create a sorter](https://biassort.com/create): Choose between a private sorter link and a public sorter submission.

## Public Content

- Public sorter pages use the path pattern `https://biassort.com/sorter/{slug}`.
- Category browse pages use the path pattern `https://biassort.com/browser/{category-slug}`.
- Only sorters with the internal status `published` are intended for Browse, search, sitemap, and public indexing.
- Sorters with `unlisted`, `pending_review`, or `rejected` status are shareable by URL only and should not be treated as public discovery content.

- Do not infer that direct URL access means a sorter has been approved for public discovery.
