Obesidian is my favorite productivity tool. I use it for all my writing, as a jernaling app, and to replace many productivity devices. Although there is a large negative side, however: no grammar check tool.
Grammarli is the best known grammar checking tool, but there is no way to add it to the obesidion. I will not enable it even if I could. Grammar processes the text on its own server, which is a possible privacy issue and is generally disabled. This is why I have come to love BeanA free and open-source option that runs perfectly on your device and can be added to a few clicks to the obesidians.
Harper is not just an obesidian tool – WordPress, Visual Studio Code, or plugins for any developer tool that supports the language server protocol. If you want to see Harper in action before installing, then there is a live demo On Harper Homepage—To type whatever you want and see recommendations.
Harper plugin for obesidian Obesidian settings can be easily installed from the Community Plugins Tab, the way you install another extension. After you download and activate it will start working immediately.
Harper may recommend spelling, while also indicating grammatical and stylistic issues. I have been trying to Harper for a week, after remembering a couple of embarrassing typo. This helps me notice easy-to-ovarluk issues, while for most parts, stay out of my way.

I feel rapidly mention of Harper than web-based tools, which makes sense, The developer was mainly motivated by speed During development. In settings you can choose between American, Canadian, Australian and British English. You can also change the settings for a specific Harper rule, allowing you to do things like using Oxford Comma.
It is not easy to use outside Harper Obesidian right now – there is no browser extension. But if you do your writing in the obesidion, or a developer using a supported IDE, Harper is a device that now integrates in your workflow – a well worth trying to try.
