What does Kerlig AI do?
Kerlig AI is a native macOS application that brings AI writing assistance directly to your desktop workflow. Instead of switching between browser tabs and AI tools, you can select text in any application, press a hotkey, and access AI-powered writing help instantly. The tool handles everything from proofreading emails and crafting Slack replies to summarizing documents and chatting with web content, all without leaving your current workflow.
What makes Kerlig AI stand out is its extensive model support—it integrates with over 350 AI models including OpenAI, Anthropic, Google, Groq, and OpenRouter, plus local options like Apple Foundation Models and Ollama. You can create custom actions for specific tasks, use global shortcuts for speed, and maintain privacy since your data stays on your Mac. The interface feels like a natural part of macOS, with seamless text insertion back into your original applications.
This tool is particularly valuable for professionals who do a lot of written communication—designers, developers, business owners, and team members who need to quickly polish messages, summarize information, or generate content. Whether you're fixing grammar mistakes before sending an important email, creating meeting notes from a lengthy document, or comparing job offers across browser tabs, Kerlig AI keeps you productive without the context switching that slows down traditional AI workflows.
