How is this different from asking a chatbot to fix my text?

It does not rewrite for you and go quiet. It points at each specific mistake, explains why it is one and proposes the alternative, with scores for grammar, vocabulary, coherence and register. The corrected text is there too, but as a comparison, not as something to hand in.

Which languages can I write in?

German, English, Spanish, French and Russian, and you can get the feedback in any of those five: you can write in German and have it explained in Spanish.

Is it useful for preparing an official exam?

As guidance, yes: every analysis includes an approximate level equivalent and there is a register specifically for exam writing. It does not replace official marking and does not predict a grade.

Writing analysis is part of the paid plans, with a monthly character allowance. The dictionary, vocabulary and games have a free plan.

How to improve your writing with AI (without letting it write for you)

The difference between asking a chatbot to fix your text and learning from your own mistakes — and how to use AI for the second one.

Pasting a text into a chatbot and asking it to fix things works: a better text comes out. The problem is that the text improves and you do not. Next time you will make the same mistake, because nobody told you what it was or why.

The difference between the two is not the model, it is what you ask of it. Rewriting produces a result. Explaining produces learning. This page is about getting the second one.

Rewriting is not correcting

When a model rewrites your text, it takes with it the information that would have helped you: what was wrong, what kind of mistake it was, whether it is a slip or a pattern you repeat. You get a polished paragraph and no clue what to watch for next time.

Correcting properly means pointing at the specific fragment, saying which rule or nuance fails, and offering the alternative. That is what lets you recognise the same mistake when it comes back — the only way to stop making it.

A practical test: if after a correction you could not explain to someone else what was wrong, you have learned nothing — you have only handed in a better text than your own.

The four things worth looking at in a text

Useful feedback separates dimensions, because they improve separately and a text can be strong in one and weak in another:

Grammar: Agreement, tenses, cases, prepositions. The most visible and the easiest to drill.
Vocabulary: Precision and range. A correct text that reuses the same five words reads below the level you actually have.
Coherence: How ideas and paragraphs connect. Plenty of texts without a single grammatical error still read badly here.
Register: Whether the tone fits the situation. Writing to an authority the way you write to a friend is a mistake, however flawless each sentence is.

What Lehrito returns when you submit a text

You write or paste a text, choose the language, the language you want the feedback in, and the register you are aiming for — formal, academic, casual, exam, informal or friendly — and you get:

An overall score and one for each dimension: grammar, vocabulary, coherence and register.
An approximate exam-level equivalent, useful for placing yourself before sitting one.
Every issue found, with its severity, the exact fragment, an explanation and the suggested alternative.
The full corrected text, to compare against yours.
Your strengths and concrete next steps.

The corrected text sits at the end on purpose: it is the prize, not the lesson. The lesson is the explained mistakes above it.

Words you got wrong can be saved and drilled later with spaced repetition or in the games — which is what closes the loop between being corrected and not repeating it.

How to get the most out of it

Write first, unaided. An assisted text does not reveal what you do not know.
Pick the register deliberately. The same text is right or wrong depending on who it is for; without saying so, feedback cannot judge it.
Read the mistakes before the corrected text. Start at the end and all you will see is the result.
Save what you got wrong, not what you already knew.
Rewrite the text yourself applying what you learned, instead of copying the corrected one. That is where it sticks.
