Kerlig

Tired of constantly switching between your work and a browser tab for AI assistance? Kerlig is a native AI writing assistant for macOS that eliminates this friction, integrating powerful AI capabilities directly into your existing workflow. It's designed for professionals who need to communicate faster and more effectively without breaking their focus.

Key Features

• ✍️ Write and Refine Anywhere Select text in any application—from Mail and Slack to Jira and Notion—and use a simple hotkey (⌥ + Space) to instantly proofread, rewrite, or shorten your message. Kerlig helps you maintain a professional and polished tone across all your communications.

• 🧠 Personalize Your AI Assistant Go beyond generic responses. Kerlig learns your unique tone of voice to generate replies that sound authentically like you. Furthermore, you can create your own custom actions in a powerful editor, tailoring the AI to perform specific tasks that fit your exact workflow, from generating code to drafting marketing copy.

• 📄 Chat with Your Documents and Media Unlock the knowledge within your files. Simply attach documents, ebooks, images, or even provide a webpage link, and start a conversation. You can ask Kerlig to summarize key points from meeting notes, extract data from a PDF report, or explain complex topics from a tutorial, turning static information into an interactive resource.

• 🔌 Access Over 350+ AI Models Kerlig puts you in complete control of your AI engine. Connect your own API keys from leading providers like OpenAI, Anthropic, Google, and Groq, or run local models with Ollama for total privacy. You can switch between models with a single click to find the perfect one for any task.

Why Choose Kerlig?

Kerlig is engineered from the ground up to be more than just another AI tool; it's a fundamental upgrade to your Mac workflow.

• Truly Native Integration, Not a Web Wrapper Unlike web-based tools that force you to constantly switch contexts, Kerlig operates natively within macOS. This deep integration means you can call on AI instantly from any app, making it a frictionless and immediate part of your process, not a separate destination.

• A Fair, Transparent Pricing Model While most AI tools lock you into a recurring monthly subscription, Kerlig offers a one-time license fee. After that, you only pay for the API tokens you actually use directly to your chosen provider, with most users spending just $1–$3 per month. For ultimate cost control and privacy, you can also use local models via Ollama for free.

• Unmatched Flexibility and Control Instead of limiting you to a single AI provider, Kerlig provides access to an extensive library of over 350 models. This unparalleled choice allows you to leverage the best-in-class models for specific needs—from the creative power of GPT-4o to the massive context window of Gemini 1.5 Pro or the speed of Groq.

• Privacy by Design Your data privacy is paramount. Kerlig sends your prompts directly to your chosen AI provider and stores your chat history encrypted locally on your Mac. When using local models, your data never leaves your machine, giving you complete peace of mind.

Conclusion:

Kerlig fundamentally changes how you interact with AI on your Mac, transforming it from a separate tool into a seamless, integrated partner that boosts your productivity. By eliminating context switching and providing unparalleled customization, it empowers you to write, research, and create more efficiently than ever before.
