How does Blindspot help me learn English?

Blindspot lets you write about any topic in English. Your text is checked for grammar errors and unknown vocabulary in real time. Mistakes become lessons — each error gets an explanation, and new words are saved to your personal dictionary automatically.

What languages are supported?

Blindspot supports 12+ native languages including Russian, German, Spanish, French, Polish, Japanese, Turkish, Ukrainian, Portuguese, Italian, and Chinese. You can mix your native language in your writing — unknown words get translated automatically.

How is Blindspot different from Duolingo or grammar quiz apps?

Unlike quiz apps, Blindspot is writing-first. You write real text, not pick answers from a list. Grammar rules and vocabulary are built from your actual mistakes, not a textbook order. Exercises adapt to your weak spots automatically.

What Blindspot Checks

Blindspot is not just for fixing your sentence. It checks many things:

Grammar Mistakes: Wrong verb forms, subject-verb agreement, etc.
Word Order: Words in the wrong place.
Prepositions: Correct use of in, on, at, etc.
Spelling: Common and uncommon spelling errors.
Punctuation: Missing commas, periods, etc.

Blindspot looks at all these things to give you a complete correction.

Examples of Fixed Sentences

Here are some examples of sentences before and after using Blindspot:

Incorrect Sentence	Correct Sentence
I didn't saw him.	I didn't see him.
She explained me the problem.	She explained the problem to me.
I am agree.	I agree.
I have 29 years.	I am 29 years old.
I very like this idea.	I really like this idea.

Why is this important? Because small mistakes can change the meaning of your sentence. Blindspot helps you avoid these mistakes.

Why Explanations Matter

Blindspot does not just fix your sentences. It explains why it makes changes. This is important because:

You learn from your mistakes.
You stop making the same mistakes.
You improve your English over time.

For example, "I didn't saw him." changes to "I didn't see him." because "didn't" already makes the verb past tense.

Common Sentence Mistakes

Let's look at some common mistakes:

Verb Forms
- Incorrect: "I didn't saw him."
- Correct: "I didn't see him."
- Why: "Didn't" is already past tense, so "see" stays in present form.
Prepositions
- Incorrect: "She explained me the problem."
- Correct: "She explained the problem to me."
- Why: We need "to" after "explained" for the person receiving the explanation.
Age Expression
- Incorrect: "I have 29 years."
- Correct: "I am 29 years old."
- Why: In English, we use "am" for age.
Agreement
- Incorrect: "I am agree."
- Correct: "I agree."
- Why: "Agree" is a verb, not an adjective, so "am" is not needed.
