Comments and Reviews
I have been using Kerlig as a Grammarly alternative. So far so good. I like that you can customise different actions and prompts so I can adapt it to my different writing contexts and styles (from drafting an email to polish an abstract or an article). Beautify UI and very easy to use.
Kerlig AI has become a game-changer in my studies. As a student, dealing with tight deadlines and difficult material is part of the job, and writing clearly and effectively can be even more challenging. That's where Kerlig AI really helps me. It makes research faster, gives me clear summaries of articles, and suggests ways to improve my writing. I honestly feel like I have a personal academic coach who is always there when I need help. The app is very easy to use, which helps me stay focused and get more done. In the end, it saves me time, improves the quality of my work, and helps me understand things better.
Kerlig has been a game changer in how I interact with LLMs. The claims are true — it reduces the need for context switching to get AI answers or completions. No more copy-pasting; I simply ask about the content, and if I want to use the response, I just select "Insert in [focused app]."
I’ve tested just about every tool out there: ChatGPT for macOS, BoltAI, Elephas, Plus AI, TypingMind, and multiple Raycast extensions. Nothing comes close to the seamless experience Kerlig offers.
The integration with macOS is seamless, making it feel like a native part of the system. It’s lightning-fast and incredibly intuitive. Kerlig has genuinely made using AI models so much easier for me! Every other app has been annoying, complicated, slow or any other drawback. Not Kerlig. Highly, highly recommended!
