Herodotus

INTERACTIVE KNOWLEDGE GRAPH

Untangle Complexity

Turn scattered facts into maps of connections, tables, timelines, and mind maps. Add events, connect them, tag them — and filter to reveal patterns invisible in linear notes.

Try: The Goal Rashomon Tenet Empty Canvas

How It Works

  1. Add events as nodes — draw causal and logical connections between them.
  2. Tag — attach What, Where, and When tags to enrich each event with structured metadata.
  3. Filter — follow chains of causality, filter by tags, and uncover patterns invisible in linear notes.
