It's been a while since MerciApp has become a part of the online proofreader industry for all those who want clean and pleasant texts to read.
With the recent integration of MAIA, its AI assistant dedicated to writing, this French solution takes a new step in editorial assistance, particularly for teachers and education professionals.
I propose you to discover together the new features of MerciApp, which make it an indispensable tool not only for the education sector, but also for all those who write frequently.

MerciApp: more than just a spell checker
Launched in 2020 in a market where competition is tough (Cuckoo Antidote), MerciApp was able to pull its pin from the game. Since then, the tool has continuously improved to offer today a smooth experience, which really fits the digital habits of teachers.
Concretely, MerciApp is installed as an extension for Chrome. Firefox or Edge. It also exists as an app for Windows. This basically means that you can write an email, prepare a course on Google Docs or post on LinkedIn without having to change tools. MerciApp integrates naturally into your digital workflow.
A proofreader that captures (almost) everything
MerciApp is based on more than 30 years of language research, identifying and correcting a wide range of errors.
Correction is done intuitively. While you type your text, MerciApp discreetly highlights the things to review. One click, and hop, it offers you a correction. Fast, without breaking your rhythm, and frankly practical to avoid scattering by having everything on hand.
Maia: an AI boost that really changes the game
The great novelty of MerciApp in 2025 is without a doubt MAIA (ThanksApp Artificial Intelligence), available since March. This feature literally revolutionises the assisted writing approach by offering much more than just a correction.
MAIA is like a Drafting Binomial which you can call at any time directly from the MerciApp extension. For a teacher who juggles between classes, assessments, emails to parents and everything else, it is a big time saver.
Maia, how does it work?
A keyboard shortcut (Basic Alt+M, but you can change it) is enough to open MAIA. You can send him a piece of text or start writing with him.
For example, a history teacher may ask him: ‘Can you create three questions for me about the French Revolution for my 4th grade students?’ MAIA then offers suitable suggestions, which you can use like this or adjust to your own taste.
A collection of really practical assistants
MAIA does not just correct: it also proposes a library of more than 20 ready-to-use assistants. Each assistant has his specialty.
An English teacher can use the translation assistant for their course materials. A French teacher can ask for help to vary the style of his sentences. And for heavy administrative documents, there are assistants who simplify the texts to make them much clearer.
AI Assistants Designed for Professional Needs
MAIA also offers assistants specifically designed for different professions, the result of a partnership with more than 150 professionals with various profiles.
An education assistant could, for example, help formulate clear pedagogical objectives according to official frameworks, generate ideas for differentiated activities or suggest constructive formulations for student assessments.
Personalization goes even further, as users will be able to create or duplicate their own wizards.
An SVT teacher could thus design an assistant specialising in the formulation of experimental protocols, while a BTS teacher could set up an assistant dedicated to writing contextualised professional situations.
MerciApp Assist: Smart self-correction for your writing
Alongside MAIA, MerciApp also offers the MerciApp Assist feature, which offers three levels of support:
• Automatic self-correction : perfect for correcting basic mistakes while you write your emails (without wasting time rereading everything three times).
• Optimization of style : useful to make your texts more alive and understandable.
• Reformulation : Super practical to simplify a complicated text for students in difficulty, or condense a large pavement.
A concrete boost on a daily basis
To prepare your classes, MAIA is a discreet but effective assistant. For example, he can suggest reading questions or reformulate a math problem that is a little too big.
And to correct copies, MerciApp makes it easy to annotate, while MAIA helps you write more personalized and positive feedback.
New developments that continue to happen
Recent MerciApp updates have made several notable improvements, such as the ability to reuse the latest one-click reformulation instructions or multilingual analysis., This is particularly useful for teachers of modern languages.
For schools, it is now possible to create teams and share access to MerciApp, This makes collaboration between colleagues easier.
Each user is entitled to his or her own small personal dashboard: corrected words, avoided mistakes, frequent types of errors. It is a great tool to know where to fish …
MerciApp is hosted in France, encrypts all data and complies with the GDPR to the letter. No text is used to train templates without your written endorsement. That is good to know.
Price side
You can test the full version of MerciApp for free. Then you will have to choose between three options:
• Free: 600 words/day, basic correction, 1 language.
• Correct (€8 excluding tax/month): unlimited corrections.
• Assist (€12 excluding VAT/month): Correct + unlimited access to MAIA + assistant library
At balance sheet time
In three years, MerciApp has gone from being a "smart little proofreader" to a IA Drafting Suite interesting. For a teacher, he is a good spelling guard ‑fou and a style coach. The arrival of MAIA brings the tool up to standard major players in the correction sector.
What I like
- Speed of correction and reformulation;
- Ready-to-use MAIA assistants;
- Detailed statistics to work on its weaknesses;
- Sleek interface, in French.
What I still expect
- Off-‑ model on macOS;
- Assistants dedicated to pedagogical grammar (identify an agreement, a type of sentence);
- Pricing "establishment team" with centralized billing.
To try without hesitation, If only ‑ for one month: your emails and copies will say thank you!
