The Copilot auto completion plugin enhances the Obsidian writing experience by integrating AI-powered auto-completion. It provides context-aware suggestions tailored to your writing, such as text in paragraphs, code in blocks, or LaTeX in math sections. The plugin uses multiple API providers, including OpenAI, Azure OpenAI, and Ollama, to generate these suggestions. It is highly customizable, offering various settings like trigger delay, prefix/suffix size, and personalized system prompts. Additionally, the plugin minimizes unnecessary API calls, and it can be easily disabled when needed for privacy reasons. Its ability to provide seamless and language-aware completions makes it a valuable tool for writers and developers using Obsidian.
