Correctify review
A flexible desktop grammar checker for users comfortable managing AI provider keys.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Correctify is an open-source desktop application for correcting grammar, spelling, and punctuation on Windows, macOS, and Linux. It is aimed at desktop users who want AI-assisted writing correction while retaining their writing style and formatting. Five selectable writing styles, custom correction rules, global keyboard shortcuts, and automatic copy-and-paste support make it suitable for editing text across desktop applications rather than working only inside a single editor.
Its provider support is a central part of the product. Users can connect OpenAI, Anthropic, Mistral, or OpenRouter, including free-model options through OpenRouter. This gives Correctify a broader AI-provider fit than a tool tied to one model service. Local usage and cost tracking can help users monitor activity, while OS-level API-key storage and encrypted credential storage address the handling of provider credentials. The app also supports English, German, French, and Turkish interface localization.
Correctify fits users who prefer an open-source desktop workflow and are comfortable supplying their own API keys. The main trade-off is its platform scope: it is designed for Windows, macOS, and Linux, with no browser or mobile access. That makes it less suitable for people who need correction across phones, tablets, or web applications without a desktop app. Users who want provider flexibility, custom correction behavior, and keyboard-driven editing should consider Correctify; those seeking a browser-first or mobile grammar checker should choose a product built for those environments instead.
