Why RealmCast
A DM That Never Forgets
Powered by frontier AI with vector memory — every choice shapes the story, every session builds the world.
Persistent Memory
The DM Remembers Everything
Plot twists, NPC names, your choices — all stored in vector memory and recalled in context. Sessions feel continuous, not disconnected.
Live Narration
Word-by-Word Streaming
No waiting for walls of text. The DM types in real time — like watching a story unfold live at the table.
Any Genre
Every World Imaginable
High Fantasy, Cyberpunk, Steampunk, Western, Horror. Set the tone — the DM adapts its voice, lore, and rules to match.
OpenD6 Dice
