Blindspot

Blindspot is an AI English writing checker for learners who want to understand their mistakes, not just have them fixed. Paste an email, a message, or a few sentences about your day to get a correction, the rule behind it, and practice built from the errors you repeat.

Familiar rules, the same mistakes. Many learners recognize a grammar rule in a textbook but still miss it in their own writing. Blindspot works from your own text to close that gap. An English interface and a Russian version are both available.

Key Features

• AI checks with explanations: Each correction comes with a short note on why it changes. "didn't saw" becomes "didn't see", because "didn't" already marks the past tense.
• Blind spot tracking: Repeated errors are grouped into shared grammar topics, so practice targets the patterns that cost you accuracy.
• Targeted grammar practice: Each topic collects sentences that share one error and follows with a short quiz question.
• Vocabulary and flashcards: Suggested words include definitions, collocations, and synonyms, and saved words can be reviewed as flashcards.
• Chrome extension: Select a word on any page to save it, or check your writing while you browse.

Who Should Use Blindspot

• English learners who write daily: Emails, chat messages, and work notes become the material you study.
• Intermediate learners stuck on the same errors: Blindspot turns the rules you keep breaking into short drills.
• Russian speakers learning English: Corrections can include native language hints and word translations.
