An AI writing workspace with smart context management and deep customization.
Think of it as SillyTavern for writing: a customizable environment where writers can collaborate with context-aware AI agents, swap models, manage prompts, and build their own creative workflows—all while keeping their work on their own machine.
Instead of treating AI as a chat window, Margin integrates it directly into the writing process. Draft scenes, brainstorm plots, maintain world lore, rewrite passages, and iterate on ideas inside a distraction-free editor designed for long-form writing.
- Markdown-Native Writing Environment — A distraction-free editor designed for long-form writing projects and documentation.
- Runs Locally — Your manuscripts, notes, and context stay on your machine. No required cloud services or telemetry.
- Optimized for Smaller Models — Works well with lightweight language models and supports Ollama, LM Studio, and OpenAI-compatible providers.
- Automatic Context Management — Organize characters, lore, outlines, and style guides into folders. Margin automatically includes the relevant context for each task.
- Customizable AI Workflows — Configure prompts, agents, and writing pipelines to match your process instead of adapting to rigid presets.
- Interactive Diff Review — Review AI-generated edits with clear inline diffs before accepting or rejecting changes.
