Kerlig AI

What is Kerlig AI?

Kerlig AI is a native macOS writing assistant that integrates AI capabilities directly into your workflow without requiring browser switching, made by Kerlig. The application runs on Apple Silicon and Intel Macs (macOS 12+) and uses global keyboard shortcuts to access AI writing functions from any application—email clients, Slack, Jira, document editors, and web browsers. Users invoke AI assistance via Option+Space to write, proofread, summarize, or edit text in context.

The tool supports over 350 AI models across multiple providers including OpenAI, Anthropic, Google Gemini, Groq, Mistral, and Amazon Bedrock, with local model support through Ollama and LM Studio. Users bring their own API keys to choose which models to use, enabling cost control and flexibility. Kerlig includes a document chat feature for analyzing attachments (webpages, ebooks, PDFs, images), reasoning model support for multi-step research tasks, and custom action creation for personalized workflows. The interface displays chat history, allows prompt editing, shows model chain-of-thought reasoning, and provides source citations. Built-in actions cover common needs like fixing spelling, improving tone, simplifying text, and converting code. The app stores messages encrypted locally on your Mac; data flows directly to chosen AI providers without server intermediaries.

Kerlig uses a pay-once model rather than subscriptions. The Basic License costs $49 for one Mac seat with lifetime updates and one year of app updates; the Pro License costs $79 for two Mac seats; the Team License costs $297 for ten Mac seats with remote deployment via CLI and priority support. All plans include vision capabilities, document attachments, preset management, and access to the full model library. The product serves 5,000+ employees and teams according to its marketing materials, with user testimonials emphasizing the time savings from eliminating context switching and the seamless native integration with macOS
