About
Kerlig is a native macOS application designed to bring artificial intelligence capabilities into every corner of the operating system. Instead of switching tabs to access tools like ChatGPT or Claude, users can trigger AI actions within Slack, Jira, email clients, or code editors using global hotkeys. The tool acts as a functional bridge between various Large Language Model (LLM) providers and the user's active workspace, allowing for seamless text manipulation, summarization, and content generation without breaking focus or requiring manual copy-pasting. The application supports a library of over 350 models, including major providers like OpenAI, Anthropic, Google Gemini, and Groq, as well as local options through Ollama, LM Studio, and Apple’s Foundation Models. It operates on a "bring your own key" (BYOK) model, meaning users pay for a lifetime license of the software and then connect their own API accounts. Core features include a chat interface for document analysis of PDFs and images, a "Deep Research" mode for multi-step tasks involving online data, and customizable "Actions" that can be programmed to perform specific transformations like converting code to TypeScript or drafting YouTube scripts. This tool is primarily aimed at professionals who handle high volumes of written communication, such as product designers, managers, developers, and content creators. Its ability to run headless or via CLI makes it suitable for power users and teams who want to standardize AI prompts across an organization. Because it supports local models, it also appeals to privacy-conscious users who prefer processing sensitive data on-device rather than sending it to external servers, with all messages stored and encrypted locally on the Mac. What sets Kerlig apart from subscription-based AI wrappers is its one-time purchase model, which eliminates recurring software fees. This provides potential cost savings for users who already maintain API access. The deep integration with macOS—including support for both Intel and Apple Silicon—ensures a low-latency experience. Its versatility in model selection allows users to compare outputs from different LLMs side-by-side to find the most accurate response for a specific task within a unified, well-designed interface.

FAQs
How do I start using Kerlig on my Mac?
After downloading and installing the app, you define a global hotkey and add an API key from a provider like OpenAI or Anthropic. You can then select text in any application, press your hotkey, and choose an action to process the content.
Can I use Kerlig without an internet connection?
Yes, Kerlig supports local models through Apple Foundation Models, Ollama, and LM Studio. This allows you to perform AI tasks on-device without sending data to external servers or requiring an active internet connection.
How does the pricing model work compared to other AI tools?
Kerlig uses a one-time payment license rather than a monthly subscription. You pay once for the software and then use your own API keys to pay only for the tokens you actually consume with AI providers.
What types of documents can Kerlig analyze?
The app includes an Attachments feature that allows you to chat with, summarize, and analyze popular document types. This includes webpages, ebooks, and images, which can be processed using Vision-capable models.
