Do you know a Spell Checker plugin

Hello
Do you know a spell checker plugin please ? ( for french )

I believe there are some (search ‘dictionary’ in Community Plugins), but also I think Obsidian’s built-in dictionary allows for multiple languages.

Try GitHub - tth05/obsidian-completr: Auto-completion plugin for the obsidian editor.

You can add your own dictionaries:

Here is also a french dictionary available (but there are other places, too):
