Mac
Write your novel with AI that runs entirely on your Mac. No cloud, no API costs, no data leaving your machine. Multi-agent AI writing studio --- fully free to start.
Loomscript is a native macOS writing studio that uses locally-running AI to help you write, edit, and manage novel-length manuscripts — with complete privacy and zero cloud costs.
WRITE WITH AI AGENTS, NOT CHATBOTS
Loomscript isn't a chatbot wrapper. It uses a multi-agent system where specialized AI agents collaborate on your manuscript:
• Writer Agent — Generates prose, dialogue, and description in your voice
• Editor Agent — Handles grammar, structure, consistency, and pacing
• Producer Agent — Coordinates tasks, maintains quality gates, and keeps your story on track
Watch them work in real time from the Agent Dashboard as they draft, revise, and refine your chapters.
100% LOCAL & PRIVATE
All AI processing happens on your Mac via Ollama. Your manuscripts, characters, and ideas never leave your machine. No API keys. No usage limits. No monthly token bills.
Optimized for Apple Silicon — runs beautifully on M1 through M4.
BUILT FOR NOVEL-LENGTH WORK
Most AI tools choke on anything longer than a blog post. Loomscript was designed from the ground up for book-length projects:
• Story Codex — A living reference of your characters, locations, plot threads, and timeline that your AI agents consult as they write
• RAG Context Engine — Automatically retrieves relevant passages from earlier chapters so your agents never lose the thread
• Hierarchical Summarization — Compresses your entire manuscript into layered summaries so agents always know the story so far
• Chapter & Scene Management — Organize your book into chapters and scenes with status tracking and word counts
PROFESSIONAL EXPORT
Print your manuscript directly from the app or export to PDF and EPUB for e-publishing. Customize page size, fonts, and formatting.
