Advanced local intelligence with privacy-first architecture

✨

Magic Polish

Highlight any text and let AI refine it instantly. Fix grammar, enhance descriptions, shorten verbose passages, or expand ideas—all with stateless operation to prevent context pollution.

💬

Brainstorm Partner

Chat with a creative AI that sees your active editor content (last ~10,000 characters) automatically. Get context-aware suggestions for plot development, character motivations, and breaking through writer's block.

📚

Lore Keeper

Mention @Chapter Name in conversations to automatically inject that chapter's content into the AI's context. Check consistency across your manuscript: "Is Alice's eye color consistent with @Chapter 3?"

📝

Summarizer

Auto-generate chapter synopses stored in synopses.json. These summaries enable the AI to understand your entire book's structure without reading every chapter—perfect for long-term context memory.

🧠

3-Tier Context System

Intelligent RAG architecture: Tier 1 injects active scene content. Tier 2 auto-detects characters and locations mentioned in your writing. Tier 3 pulls specific chapters on-demand via @mentions. Context that's always relevant, never overwhelming.

🎭

Tone Matching

AI automatically detects and matches your writing style—whether comedy or horror, formal or casual—ensuring suggestions that fit your narrative voice perfectly.

🎯

Smart Editing Modes

Improved "rewrite" vs "edit" behavior prevents overly aggressive changes. The AI understands when to polish versus when to completely reimagine your text—with presence/frequency penalties to reduce repetition.
