The Companion plugin is an AI-powered autocomplete feature for Obsidian note-taking and personal knowledge management platform. With Companion, you can write notes more quickly and efficiently by receiving smart suggestions based on the context of your writing. The plugin uses OpenAI's GPT-3 and GPT-3.5 models, including ChatGPT, and locally hosted Ollama models to generate tailored suggestions that adapt to your writing style. You can accept or ignore these suggestions as you write, allowing you to take advantage of AI-powered productivity without interrupting your workflow. Whether you're a student, researcher, or knowledge worker, Companion can help you streamline your note-taking and knowledge management processes.
