The Harper plugin integrates a local grammar checker directly into Obsidian, providing users with instant, private, and open-source grammar correction. Unlike other tools, Harper runs entirely on your device, ensuring your data stays secure without the need for additional setup or internet connectivity. The plugin automatically checks your documents in real-time, highlighting errors as you type. Hovering over an error reveals suggested corrections for a seamless editing experience. With a lightweight design and efficient functionality, Harper enhances writing productivity while maintaining user privacy.

The Password Protect plugin enables users to secure their Obsidian notes and folders by setting a password, ensuring that sensitive content like journals remains hidden. Hidden notes are not visible in search results or graph view until the correct password is entered. The plugin works by changing file extensions to hide them, offering a layer of protection against casual viewers. While the files are not encrypted, they are inaccessible without the password. The plugin also allows for syncing hidden files across devices using services like Syncthing, provided certain conditions are met. It provides basic protection and is ideal for users looking for privacy within their Obsidian vault.

The Blur Mode plugin for Obsidian is a practical tool designed to help users maintain privacy or focus by blurring specific elements within their notes. Whether you're protecting sensitive information or simply reducing visual clutter, this plugin gives you precise control. Users can create and manage blur presets through an intuitive panel, allowing for easy selection of elements to blur or restore to full visibility. The blur effect is fully customizable, with adjustable intensity and even a keyword-based option to blur items containing specific terms. Activating or deactivating the blur is as simple as clicking a ribbon icon, making it effortless to toggle the effect as needed. The plugin also supports real-time previews, ensuring you can refine your settings on the fly. If you're looking to balance note security and accessibility, Blur Mode provides a seamless and user-friendly solution tailored to Obsidian's ecosystem.

Peekaboo is a privacy-focused Obsidian plugin that allows users to easily hide specific files and folders within their vault, offering greater control over content visibility. With options to password-protect your settings and use patterns to hide multiple files at once, Peekaboo makes it simple to manage sensitive notes. It includes a ribbon icon and command palette integration, so toggling visibility is quick and efficient. For those looking to keep certain files accessible, Peekaboo lets users configure exceptions to keep select files visible, even within hidden folders. Keep in mind, though, that Peekaboo hides files visually but doesn’t encrypt them, so combining it with Obsidian's "Excluded Files" feature is recommended for more comprehensive privacy.

Obsidian's Privacy Glasses plugin allows users to blur their notes and sidebars for added security.

While reporting and account reconciliation features are in development, this plugin provides a self-sufficient way to track finances using the open-source Ledger CLI.

The NSFW filter plugin allows users to toggle the visibility of files marked as NSFW in Obsidian. By moving such files into a designated NSFW folder, users can hide them from view when sharing their notes. The plugin helps protect personal or sensitive content from being displayed publicly. It automatically saves the original location of files and can toggle them back and forth between the main vault and the NSFW folder. This functionality is ideal for users needing to manage sensitive information without compromising privacy in shared environments.

It can be activated through the commands palette, offering a quick toggle feature. The plugin also includes planned improvements, such as regex-based garbling and custom display fonts for garbled text, enhancing its versatility for privacy-conscious users.
