About Relatrix

Most knowledge-management tools are glorified bookmarks. You gather articles, highlight text, save links, and then forget everything. Relatrix changes that. Built on a single, uncompromising philosophy: Information only becomes knowledge when you engage with it through active reflection. Every resource you save is a starting point, not a destination. Relatrix provides a multi-modal toolkit to break down, question, and connect information across diverse formats.

Feature Overview:

- Topic Library: Organise your intellectual world into curated folders of resources. Visually organize topics with a fully customizable color picker. You can add web links, PDFs, markdown notes, and absolutely any kind of file as a resource.

- Multi-Modal Resource Timeline: A single chronological feed that unifies your reflections, annotations, and visual captures.

- Tag Management Hub: Manage, explore, and filter your resources across all topics using custom tags.

- Reflection-First Entry: When you save a PDF, web page, markdown note, or any other kind of file, Relatrix encourages you to capture an Opinion immediately.

- Knowledge Links & Tags: Cross-reference other resources, topics, or insights using [[double-bracket]] wiki-style links and organize entries with custom tags using a unified dropdown.

- PDF Reader & Annotation: Flip pages, highlight passages, create bookmarks, and perform web lookups.

- Note Editor: A minimalist markdown canvas designed for clarity.

- Relatrix 3D Knowledge Discovery: A live, physics-simulated 3D graph that renders the connective tissue of your knowledge base.
