Ligature
A fast, offline space for writing, thinking, and organizing ideas
An offline writing app that lets you write, organize ideas in documents and folders, and optionally sync across devices without requiring an account.
About this launch
Ligature is an offline writing application designed for composing, thinking, and organizing ideas. Your writing is stored locally on your device with no account requirement, giving you complete control over your files and backups.
The app features a block-based document editor with support for headings, lists, callouts, tables, and annotations. You can organize your writing in folders and add labels and tasks for additional structure. Ligature includes built-in AI capabilities, allowing you to connect OpenAI, Claude, Ollama, or LM Studio while keeping your API keys local.
While the core writing and organizing features are free, Ligature Sync is an optional paid service that keeps your library synchronized across multiple devices. The app works entirely offline, with sync and connected services only requiring internet when actively used.
