It doesn't underline your mistakes.
It fixes them, and tells you why.
Paste your text: objective mistakes are corrected instantly, each one flagged, each one undoable in a click. And for every correction: the rule, why it applies here, an example.
→ No sign-up, no credit card. The free trial is not a crippled version: only text length is capped.
Proofreading — Master's thesis
Why? In French, a past participle used with « être » agrees with the subject. Here the subject is « les données », feminine plural → collectées.
What sets it apart
Five reasons to prefer it
Nothing to install, nothing to create
Three secondsPaste your text on the home page and it gets corrected. No sign-up, no credit card, no crippled version.
The free trial isn't a mutilated demo
Everything but lengthDetection and explanations exactly like a paid account. We don't strip features to force your hand.
Correction happens on its own
It acts, then hands back controlObjective mistakes are fixed as soon as you paste, each flagged in the text, each undoable in one click. Others underline; this one corrects.
It tells you why
The teaching angleNot « agreement error », but the rule, why it applies here, an example. A proofreader that teaches you to stop needing it.

3 levels of scrutiny
Fast, balanced, expert — depending on the time you have.
Language detection
Paste English, it corrects in English. Nothing to set.
A score out of 20
Weighted by length: 3 mistakes in a tweet ≠ 3 in a thesis.
Personal dictionary
Your proper nouns and jargon stop being flagged.
Understand, not just correct
It tells you why
A proofreader that corrects without explaining keeps you dependent. This one does the opposite: for every mistake it gives the rule, explains why it applies in your sentence, and offers an example. Teachers and trainers already use it this way.
The rule
Stated plainly, without needless grammatical jargon.
Why here
The link between the general rule and your exact sentence.
An example
A neighbouring, correct sentence to anchor the rule.
Beyond correction
Your texts, managed

The teaching explanation: the tool teaches the student rather than doing the work.
Frequently asked
Before you message us
Do I need an account?
No. Paste your text on the home page and it gets corrected. An account is for saving documents, keeping history and lifting the length cap.
Is the free trial limited?
It is complete feature-wise: same detection, same explanations as a paid account. Only text length is capped.
Does it replace a professional proofreader?
No, and that isn't the goal. LexiMboa does the first pass — the objective mistakes — so human review can focus on substance and style.
Do my texts go elsewhere?
Proofreading is self-hosted on our servers. However, if you ask for an explanation, the sentence concerned is sent to Mistral AI to write that explanation.
Does it work in English too?
Yes. The language is detected automatically: paste English and it corrects in English. The interface is bilingual French / English.
Can I use it offline?
LexiMboa installs like an app on your phone or computer and stays usable offline for reading and writing.
