Kerlig

Kerlig is a powerful and elegantly designed AI writing application built exclusively for macOS. It acts as a native assistant that integrates directly into your operating system, aiming to save you countless hours on written communication tasks. Whether you're drafting a critical email, replying to a Slack message, creating a Jira ticket, or proofreading an important announcement, Kerlig puts the power of advanced AI models right where you need them. It eliminates the constant context-switching of opening a browser tab for an AI chat, allowing for a more fluid and efficient workflow.

Trusted by thousands of professionals, Kerlig is built for speed and personalization. It supports over 350 AI models from leading providers like OpenAI, Anthropic, Google, and Groq, as well as local models via Ollama and LM Studio. This flexibility allows you to choose the best model for any task, all within a single, unified interface. Your data remains private, as messages are sent directly to the AI providers and stored encrypted on your Mac.

How to use Kerlig

Getting started with Kerlig is simple and intuitive, designed to integrate AI into your workflow in minutes:

1. Download and Install: Download the Kerlig app for your Mac (supports both Apple Silicon & Intel on macOS 11+).

4. Activate Kerlig: Select any text in any app (a browser, text editor, email client) and press your designated hotkey. Kerlig will launch with the selected text as context.
5. Choose an Action: From the Kerlig window, choose a built-in action like 'Fix spelling and grammar', 'Summarize', or 'Improve writing'. You can also run custom prompts or use your own created actions.
