Obsidian is my favorite productivity tool. I use it for all of my writing, as a journaling app, and to replace multiple productivity tools. There’s a big downside, though: no grammar checking tool.
Grammarly is the best known grammar checking tool, but there’s no way to add it to Obsidian. I also wouldn’t enable it even if I could. Grammarly processes text on their own servers, which is a potential privacy issue and also generally inefficient. This is why I’ve come to love Harper, a free and open-source alternative that runs entirely on your device and can be added to Obsidian in a couple of clicks.
Harper isn’t just an Obsidian tool—there are also plugins for WordPress, Visual Studio Code, or any developer tool that supports the Language Server Protocol. If you’d like to see Harper in action before installing, there’s a live demo on the Harper homepage—just type whatever you want and watch the recommendations.
The Harper plugin for Obsidian can easily be installed from the Community Plugins tab in the Obsidian settings, the way you’d install any other extension. After you download and activate the plugin it will start working immediately.
Harper can make spelling recommendations, while also pointing out grammatical and stylistic issues. I’ve been trying out Harper for a week now after missing a couple of embarrassing typos. It’s helped me notice easy-to-overlook issues while, for the most part, staying out of my way.
What do you think so far?
