Hunspell

What is Hunspell?

Hunspell is a mature spell‑checking library that has been part of the Linux ecosystem for over a decade. It started as a fork of the OpenOffice spell checker and has since become the default backend for LibreOffice, OpenOffice, and many other applications.

It is aimed at users who need accurate, language‑aware spell checking in a variety of text editors and office suites. It supports complex languages, hyphenation, and custom dictionaries.

Compared with Windows tools like Grammarly, Hunspell is lightweight and fast, but it lacks the advanced grammar‑checking and style‑suggestion features that Grammarly offers. It feels more like a traditional spell checker than a full‑blown writing assistant.

Best for: Users who need a reliable, language‑aware spell checker for Linux office suites and editors.

Tips for Windows users

If you’re moving from Grammarly, expect to lose grammar suggestions and real‑time style feedback. Hunspell works with standard dictionary files (.dic/.aff) that you can download or create yourself. Most Linux editors expose a spell‑check toggle; shortcuts vary (e.g., LibreOffice uses Ctrl+Shift+S). Workflow changes: you’ll need to enable the spell checker manually and add custom words to your personal dictionary via the editor’s settings.

File formats are the same as any standard text editor; you can open .docx, .odt, .txt, etc. The main difference is the lack of a cloud‑based service; everything runs locally.

If you need grammar checking, consider installing LanguageTool or using a browser extension that works on Linux.
