LoneWriter
Privacy-first, open-source novel editor with Local RAG.
LoneWriter is a professional, distraction-free writing app specifically designed for novelists and creative writers who refuse to compromise on privacy. Built with the high-performance Antigravity framework, it offers a seamless, aesthetic experience (Glassmorphism & Dynamic Themes). LoneWriter is designed with a privacy-first architecture: you have full control over your data, with the choice to run everything locally via Ollama/LM Studio, or connect to third-party APIs using your own keys.
Hi Product Hunt!
I built LoneWriter because, as a writer, I was frustrated with two things: AI tools that forget my characters after three chapters, and the lack of real privacy in modern editors.
Most AI writing tools send your creative soul to a cloud server. I wanted something different. LoneWriter is a distraction-free PWA that runs entirely in your browser.
What makes it different?
- Local RAG (Semantic Search): Uses local embeddings (all-MiniLM-L6-v2) to dynamically track your previous chapters. It automatically retrieves relevant context so the AI always knows what happened in the previous scene without you having to lift a finger.
- MPC Compendium (Plot & Memory Control): This is the "brain" of your story world. A dedicated entity management system (characters, locations, objects) that injects critical data in a structured way. While the RAG searches by similarity, the MPC ensures that facts (like your protagonist being left-handed) remain immutable.
- Total Privacy (Local-First): Your manuscripts belong to you and no one else. You choose: either use local models via Ollama/LM Studio for 100% privacy, or connect your own API keys if you prefer external power.
- Lag-free PWA Core: An ultra-fast, minimalist PWA interface with dynamic themes, designed to make you forget you're using complex software so you can focus solely on writing.
It's free, open-source, and built for people who actually care about their stories. I’d love to hear your feedback and answer any questions!
Happy writing!
