It supports both local models through Ollama and OpenAI-compatible APIs, allowing users to choose between fully offline workflows or hybrid setups. The plugin introduces an “Action Palette” system that enables users to run predefined or custom AI-powered actions on selected text, notes, or entire documents. It integrates deeply with Obsidian’s structure by pulling context from backlinks, linked notes, and even external files like PDFs to enhance responses. The system also supports multimodal capabilities, including image analysis when paired with compatible models. Users can create reusable prompts, install community-provided actions, and manage workflows directly inside their note-taking environment.

Monaco Editor is the rich, browser-based code editor that powers Visual Studio Code, providing advanced editing capabilities as a standalone embeddable library for web applications. Models are at the heart of Monaco editor. It's what you interact with when managing content. A model represents a file that has been opened. This could represent a file that exists on a file system, but it doesn't have to. For example, the model holds the text content, determines the language of the content, and tracks the edit history of the content. An editor is a user facing view of the model. This is what gets attached to the DOM and what your users see visually. Typical editor operations are displaying a model, managing the view state, or executing actions or commands.

AstroNvim is an aesthetic and feature-rich neovim config that is extensible and easy to use with a great set of plugins. AstroNvim is provided as a plugin that can be installed with the lazy.nvim plugin manager and then used to import all of the plugin configurations that AstroNvim provides. To quickly get started it is recommended to start with the official AstroNvim Template which provides a great starting point for a new AstroNvim based configuration. We found other Neovim configurations either being powerful out of the box but hard to customize, or easy to customize but minimal out of the box functionality. AstroNvim aims to find the middle ground with a great out of the box experience while empowering the user to make tweaks where they want.
