Kerlig is an awesome AI aid for text-based work: write, rewrite, summarize, explain, extend, translate text literally at your fingertips in any macOS app or the OS itself. It integrates a variety of GenAI LLMs (Generative AI Large Language Models) like ChatGPT, Claude, Llama3, Mixtral, etc. via your own API key(s), so you can decide what model you use for your specific purpose. You can even switch tonality and define your own system prompts to better fit your needs. Installation is "mac-like" super easy, and meanwhile, I use it daily for nearly any text-based work. The documentation is very good, and support in case of questions is really quick. A big plus is also the fact that it comes as a one-time-payment app. No recurring fees! The only thing you pay for after purchase are the tokens you use via the API(s) of your AI service provider(s). Great!

Since using Kerlig, switching between my operating system and browser has become much more efficient (you know the pain of all the back-and-forth work between any app and the browser, right?). Available shortcuts are super handy and easy to grasp after a few uses. I highly recommend trying it – I think you'll enjoy it as much as I do. Plus, the customer support team has been exceptional.

Very fast, stable, and intuitive app with a well-designed onboarding process. It helps me keep up with my daily tasks at work. I love this new feature: Chat Presets, and the fact that I can switch between each of them in milliseconds is so awesome!
