SpellCheckPlus review
A focused web checker that combines corrections with exercises and writing practice.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SpellCheckPlus is a browser-based English writing checker from Nadaclair Language Technologies Inc. It is designed for learners and educators who want more than basic proofreading, with feedback that supports self-correction. The service identifies spelling and grammar errors, confused words, punctuation and spacing problems, capitalization issues, and grammatical structures. Its positioning suits French learners wanting feedback and exercises, although the checking language is English only.
The free plan provides online English spelling and grammar checking for texts of up to 500 words. A five-day free trial is also available. SpellCheckPlus Pro expands the workflow with a resizable, fullscreen editor, text archiving through a writing portfolio, categorized error summaries, interactive grammar exercises, lexical enrichment suggestions, and no advertising. This makes the paid tier more useful for learners who want to review recurring errors, build a collection of writing, and continue practicing after each correction.
The product’s strongest distinction is its learning-oriented feedback rather than a broad software ecosystem. It runs on the web, with no standalone personal-computer version and no integrations listed, so it fits users who are comfortable working in a browser and do not need connections to other writing tools. Choose SpellCheckPlus for focused English correction, explanations, exercises, and lexical development. Choose an alternative if you need support for multiple languages, desktop software, or an integrated writing workflow across other platforms.
