An Gramadóir review
A capable free Irish-language checker for developers, editors, and language projects.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
An Gramadóir is an open-source grammar-checking engine and natural-language-processing platform for Irish (Gaeilge). It is designed for developers, linguists, educators, editors, and communities working with a language that has limited computational resources. The software checks grammar and spelling, while also supporting sentence segmentation and part-of-speech tagging. Access is available through a web interface, command-line interface, library, and API, with editor interfaces for Emacs, Vim, and OpenOffice.
Its main strength is the range of ways developers can incorporate Irish-language checking into existing workflows. XML/API output supports integration with other programs, while the Perl library/module provides a programming route for projects that need deeper control. The published interfaces also include Emacs, Vim, and OpenOffice, and Google Docs is listed among its integrations. This combination makes An Gramadóir more than a standalone checker: it can support editorial tools, language research, educational projects, and custom applications.
The trade-off is focus. An Gramadóir’s current implementation is Irish, so teams seeking multilingual grammar checking will need a different product or additional tools. Its command-line, API, tagging, and library capabilities are valuable for technical and language-focused users, but may be more than a casual writer needs. Choose it for free, open-source Irish grammar support and integration flexibility; choose an alternative when broad language coverage or a wider consumer writing platform is the priority.
