Prefix Tree Engine

Trie (Prefix Tree) Visualizer

A Trie stores strings character-by-character, sharing common prefixes to achieve O(m) lookup (where m is the key length). Insert words and search to see the structure grow and shrink in real-time.

Shared Prefixes

Common prefixes share a single path.

O(m) Search

Key length — not dictionary size — matters.

Autocomplete

Power behind search suggestions.
