It runs as a native desktop application requiring macOS 10.15 or later and is activated system-wide via a customizable keyboard shortcut, so users never need to leave their current app. Core features include grammar and spelling correction, text rewriting, summarizing, translation, tone adjustment, and OCR-based text extraction from images. A Prompt Library offers built-in roles such as email writer, marketing copywriter, and software engineer. Custom Presets let users save preferred tones and styles for consistent output. The app captures content from browsers, Slack, Notion, Apple Mail, and other macOS apps automatically. Kerlig AI connects to multiple AI providers using user-supplied API keys, including OpenAI, Anthropic, Google Gemini, Perplexity, and others, with no recurring subscription fee. An on-device model option processes data locally with no internet connection required. Teams can deploy and manage API keys and licenses centrally via a command-line interface.

The developer doesn't rush to add features and is very active in the community. Still in the early stages, but love to see what this product grows into. > > **Cons**: Can't fully replace an LLM client; still have to use something like BoltAI to fill in parts that Kerlig fails at yet. > > Very fluid and fast, however, we would love it if we could have some essential features added as fast as possible and hopefully increase the update cycle. Even if it's a very small feature, the community would love it if we had a feature every week. Keep everything exciting\! ----- ### "Purchased through pre-order. It turned out to be an excellent deal\!" — 5.0/5 > **Michał** | *19 April 2024* | Financial Services | Recommendation rating: 10.0/10 > > **Pros**: I really like the native experience and how accuracy feels like an integrated part of MacOS. It really helps me improve my text quality and brainstorm in no time\! > > **Cons**: Maybe onboarding could be a bit more interactive. Besides that, everything went very smooth\! 10/10. > > It's great so far\! I can't say anything but good things. Kerlig is very stable. Nothing glitches. It feels like a mature product, and it's hard to believe it just started. \[sensitive content hidden\](creator) did a great job\! I wish you all the best, Jarek\! Good luck with the next iterations\! I hope Kerlig will remain simple yet powerful\! ----- ### "An amazing AI client to call while working on any app on my Mac" — 5.0/5 > **Aanya** | *20 April 2025* | Education Management | Recommendation rating: 9.0/10 > > **Pros**: I can invoke it while working on any app on my Mac and execute AI commands according to my requirements in the moment. > > **Cons**: There is a shortcut to invoke the overall app, but to execute a particular AI command, there are no hotkeys. I always have to open the app and then select the particular AI command that I want to execute from a drop-down, which can be a tad cumbersome. > > Overall, this has been a delightful experience, especially because of the UI/UX, which is top notch. It helps me work with any text on any app and execute various AI commands on it, like summarizing, extracting key points, fixing grammar, translating text, etc. ## Links - [View on SoftwareAdvice](https://www.softwareadvice.ie/software/520085/Kerlig) ## This page is available in the following languages | Locale | URL | | en | | | en-AU | | | en-GB | | | en-IE | | | en-NZ | | ----- ## Structured Data
