Who has never dreamed of always writing impeccable and error-free texts? whatever the level of difficulty?

For my part I took correction software.

This is especially important when you know that 1 mistake in 1 CV can change a career …
But not all are equal in terms of quality and cost. So I tested the most popular on the market, and found 2 correct ones to add in the comparison.

The best spelling (and grammar) checker is in my humble opinion and without hesitation the Antidote 10, not least because of the many features it offers and the fact that it does not let go of big mistakes that other software cannot identify.

Buying guide: how to choose the right spell checker?

Antidote 10 - Corrector and dictionaries for French or English

Whether analyzing a text of a few hundred words, or an entire guide, it is best to use the most effective corrector. However, finding good patch software is not as easy as you might think. Several criteria must be taken into account. A few are shown below.

The first thing to check is the ease of use of the spell checking software. It should be easy to activate its intuitive internal browser. In one click, you should be able to carry out your research and access the various functionalities (dictionaries, guides, etc.). A model with smart search would be an excellent choice. In addition, the interface must be ergonomic. This is essential for progress in writing.


This is one of the most important criteria. No matter how good a corrector is, if it’s not compatible with your operating system, you won’t be able to use it. So choose software that supports most systems: Windows, Mac OS, Linux, etc.

Once installed, it must be able to integrate directly with browsers and word processing tools (Word, PowerPoint, Outlook, Mail, Open Office, Keynote, etc.). So you no longer need to copy the text and paste it into the corrector each time you check. It will be enough to activate it with a click when you need it.

The capacity

This concerns the number of characters supported by the software during the correction. This is limited in some products, but in others it is not. It will all depend on how many words you are used to writing. In addition, also check whether the program corrects mistake by mistake or takes into account the whole text.

The performance

The performance of spelling and grammar correction software is linked to its analytical ability. This must be able to detect even the most complex errors. To this end, it must include filters to examine the text on all linguistic aspects (syntax, logic, lexicon, etc.). In addition, some programs are able to report long sentences and repetitions. This is a necessary asset if you plan to use the product in a professional setting. This will help you improve your writing style.

The options offered

Usually, spelling correction software offers two main tools: a corrector and dictionaries. This is more than sufficient for typical use: detecting errors and correcting them. However, if you want to get faultless writings, it will take more than that. In addition to the standard functions (synonyms, definition and antonyms), the dictionaries must also offer the following options: conjugation, lexical field, historical evolution, etc.

Make sure the product has well-detailed language guides. This will improve your level in spelling, grammar and phonetics. Some models even come with an encyclopedia. It is also a very interesting option and very popular with Internet users.
