AI writing studio where an agent researches your story during generation. Build a codex of characters, locations, and plot notes; outline in beats. Hit generate — the agent reads your outline, pulls relevant codex entries and prior scenes, and streams contextually aware prose. Deep Writer mode runs research → draft → analyze → refine with a visible step trail. Margin cards put your codex next to your prose. BYOK on hosted. 7-day trial. Self-hostable (MIT).
