This Obsidian plugin is an unofficial integration of Antidote, a powerful grammar checker.
Antidote supports these languages:
This plugin works with Antidote 10 (using Connectix version 11 or higher) and higher, and Antidote web, on macOS (11 and higher), Linux and Windows.
This plugin does not work on smartphones.


Antidote is a separate application, sold by Druide. This plugin is only a bridge between Obsidian and Antidote: it corrects nothing by itself, and it cannot install anything for you. You need, on the same computer as Obsidian:
If Antidote already works in another application but not in Obsidian, your Connectix is most likely too old: see Installing Connectix 11 with Antidote 10.
This plugin can be found in Obsidian's community plugins library, Settings > Community Plugins > Browse: antidote-grammar-checker-integration
Download main.js, manifest.json, styles.css from the latest release and put them into <vault>/.obsidian/plugins/antidote-grammar-checker-integration folder.
Antidote 10 ships with Connectix 10, which this plugin does not support. Keeping Antidote 10 is fine, but Connectix has to be upgraded to version 11 or higher: it is the bridge between Obsidian and Antidote (10, 11+, web), and the two versions do not have to match.
Connectix 11 can be downloaded from your Client Portal, under the "Useful links" section: "Connectix Utility for Antidote Web".
Its installer may refuse to run while Antidote 10 is still installed:
.msi file it extracted (reported by @GittyBob)On Linux, Antidote 10 is the latest supported version of Antidote, so this upgrade is the only way to use the plugin on that system.
This plugin adds 4 icons into the status bar:

You can show or hide every icon from settings.
It also adds command for corrector, dictionary and guide.
The "Correct All" send the whole document to Antidote, or, the selection, whereas the "simple correct" send the text depending the position of the cursor and the selection. The "simple correct" has the same behavior as the official integrations in other software (VS Code, Word, etc.).
"Antidote was not found." Neither Antidote nor its Connectix agent could be located on this computer. Check the requirements: both are separate applications that have to be installed on their own.
"Unable to communicate with Connectix Agent (Antidote)." Antidote is installed, but the plugin could not talk to it. In order:
The developer console, Ctrl+Shift+I (Cmd+Option+I on macOS), shows the underlying error. Please include it when reporting an issue, along with your Antidote, Connectix, Obsidian and system versions.
