Feuillets Grammalecte

Standalone project: Sargon01/feuillets-grammalecte.

Feuillets Grammalecte is the official language-analysis companion plugin for the Feuillets writing studio. It embeds Grammalecte 2.3.1 locally for French spelling and grammar checking directly in Obsidian.

Note: This is an independent integration for Obsidian and is not the official Grammalecte project.

Requirements

• A current version of the Feuillets plugin that exposes the text-analysis provider API must be installed and enabled.
• Feuillets Grammalecte supplies local language analysis without adding a grammar engine to Feuillets itself.

Features

• French spelling and grammar checking: Detects spelling, agreement, punctuation, typography, and repetition issues.
• Editor-first live correction: Feuillets runs checks for the current document after a short typing pause. Normal correction works directly in the editor; Relecture remains an optional review and analysis surface provided by Feuillets.
• Correction actions: Left-click an underlined issue to open correction actions. Spelling suggestions are loaded lazily, with up to 10 interactive suggestions. You can also choose Ignore this occurrence or Add to dictionary for spelling issues.
• Personal dictionary: Ignored occurrences last for the current session only. Learned words are saved in the plugin data.
• Distinct editor diagnostics: Feuillets renders the companion’s spelling diagnostics with a wavy underline and grammar diagnostics with a visually distinct dotted or dashed underline; the distinction does not depend on colour alone.
• Linguistic analysis: Lexical richness, lemmas, -ment adverbs, passive verbs, and average sentence length remain available.

Feuillets can use this provider for live correction in both its standard editor integration and Continu view.

Privacy and local processing

Your text is never sent to an external server. Grammalecte and the fr-classic French dictionary are embedded in the plugin, so no network connection or runtime download is required. The compressed resources are loaded locally on first use and run in a reusable local Worker created from a Blob URL.
