Overview
Blindspot is an English writing checker for learners who want to know why a sentence is wrong, not just that it is. Paste a message, an email, or a few sentences about the day, and it flags the mistake, explains the grammar rule behind it, and builds practice from the errors that keep repeating.
Key Features
- Explained corrections: every fix comes with a plain-language note on the rule, such as why didn't saw becomes didn't see.
- Personalized grammar drills: exercises are grouped by the shared topic behind a learner's mistakes.
- Vocabulary saving: suggested words can be saved with definitions, collocations, and synonyms.
- Chrome extension: words can be saved and writing checked while browsing, without switching tabs.
- Free start and level test: accounts are free to create with no card, and a level test suggests where to begin.
It suits intermediate learners who would rather understand a rule than accept a silent autocorrect.
