About

An interactive, browser-based knowledge-graph explorer for the public domain. It presents 53 hexagonal galleries across three floors (21 sciences, 24 literature, 8 wisdom) holding 837 public-domain primary works, connects them with associative trails after Vannevar Bush's Memex, and answers free-form questions through an AI Oracle powered by Google Gemini.

Features

Problem
Flat lists and search results obscure relationships between subjects.
How it works
Presents 53 hexagonal galleries connected by edges representing historical or conceptual relationships.
Result
More serendipitous, contextual discovery of related classics.
Why
Readers can follow the lineage between ideas instead of starting each search from scratch.
Problem
Readers need access to the source texts behind discovery records.
How it works
Opens works in an in-page reader using texts from Project Gutenberg, the Internet Archive, or Wikisource.
Result
Readers can move from discovery to free primary texts without an account.
Why
The Index is a discovery layer rather than a text host.
Problem
A broad collection can be hard to navigate at different levels of detail.
How it works
Offers a Visual Explorer, a whole-floor Cortex Map, direct gallery links, and filterable master booklists.
Result
The collection supports both exploratory and targeted research workflows.
Why
Users can enter through spatial browsing, an overview map, or a conventional list.
Problem
Users may need help tracing a question across many fields and books.
How it works
Provides the Nexus Oracle, a Gemini-powered assistant that reasons over the Archive map and points answers back to collection works.
Result
Readers receive archive-grounded starting points for cross-subject inquiry.
Why
It is restricted to the held collection rather than the open web.
Problem
Personal reading sequences are difficult to preserve and share.
How it works
Lets users build, name, and share ordered Reading Trails as a single URL.
Result
Users can create and circulate guided curricula or research journeys.
Why
Trails make associative paths through connected galleries reusable.
