Corrector.app review
A free, multilingual proofreader for quick corrections across web, browsers, and mobile.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Corrector.app is an online spelling, grammar, and punctuation checker for students, professionals, and other writers. Users paste text into its web editor, review detected errors and correction suggestions, and copy the revised text. The service also offers writing tips, multilingual proofreading, browser extensions, and iOS and Android applications listed through its download area. It is aimed at people who want accessible proofreading without a subscription or account requirement for the web checker.
The published Free plan includes spelling, grammar, and punctuation checking, while the web checker requires no account registration. Corrector.app states that its checking tools are free, and no usage restrictions are stated for the Firefox extension. Beyond error detection, the product provides correction suggestions and writing tips, giving users more than a basic spellcheck. Its focus remains practical and narrow: correcting written text rather than presenting a broad writing, collaboration, or document-management workspace.
Platform coverage is a notable part of the offering. Corrector.app lists Chrome, Firefox, and Edge browser extensions, along with iOS and Android applications, and it identifies Microsoft Word and other document applications as integrations. The web workflow is still centered on pasting text into the editor, so writers who need deeper in-document editing or clearly defined application workflows may prefer another grammar checker. Choose Corrector.app for free multilingual proofreading across web, browser, and mobile contexts; consider alternatives if advanced feature depth or more specific integrations are central to the buying decision.
