Kerlig

Kerlig is a macOS-native AI writing application designed to reduce the time professionals spend on everyday written communication.

Users can accept or reject each suggestion individually, maintaining control over the final output. A distinctive capability is the “chat with documents” feature. Users can upload PDFs, ebooks, images, or web page content, and then ask questions about the material in natural language. For example, a project manager could upload a lengthy product specification and ask “What are the key deadlines in section 3?” or a researcher could query a technical ebook for specific data points. The AI interprets the content and returns concise answers, pulling relevant quotes or summaries. This turns the app into an interactive research assistant that works with static files. The application also supports learning from video content. If a user is watching a tutorial or a r
