Blindspot

Blindspot is an AI-powered English writing checker that not only highlights mistakes but also explains the underlying grammar rules, turning each error into a personalized learning opportunity.

Users can paste or type English text (30–5000 characters) and receive instant corrections with clear feedback, such as why “didn’t saw” becomes “didn’t see” and vocabulary suggestions like changing “готовился” to “was preparing”.

The platform offers:

• Real‑time grammar, vocabulary, and collocation checks powered by OpenAI.
• Personalized practice flashcards and word‑saving features to build a custom dictionary.
• A free English level test to get started.
• Chrome Extension for checking writing while browsing and saving words on the fly.

Ideal for language learners, professionals, and anyone who wants to improve their English through authentic writing, Blindspot transforms weak spots into targeted practice without requiring a credit card to begin.
