About Kerlig
Kerlig is a desktop AI writing assistant designed for macOS users who need AI-powered writing help inside any application, including email, Slack, and Jira, without switching to a browser. It provides system-wide writing actions for proofreading, spelling and grammar fixes, rewrites, tone adjustments, summarization, translation, and structured outputs like converting text into a TypeScript interface. Users can choose from over 350 AI models via their own API keys from providers such as OpenAI, Anthropic, Google, Groq, and OpenRouter, or use local models like Apple Foundation Models, Ollama, and LM Studio. The tool supports chatting with attachments including PDFs, ebooks, documents, and images, with features like chat history, prompt editing, and response regeneration. Kerlig also offers shortcuts and automation through global hotkeys, built-in and custom actions, presets, and team deployment options such as remote CLI deployment and headless mode. The tool operates on a one-time license model with no subscription, though token usage is billed through connected providers. It emphasizes privacy by sending messages directly to providers and storing data encrypted locally on the Mac.
