A translator, a grammar checker and a paraphrasing tool solve different problems. Choose the wrong one and you may get fluent French without understanding a correction—or change what you meant to say.

Choose a tool for your task
DeepL Translator: understand a passage
DeepL Translator is a starting point when you need to understand text in another language. Read the whole passage before accepting individual words: a technically correct translation can still miss a classroom-specific meaning.
Try this: translate one sentence, identify the subject and verb, then compare it with the original. Check unfamiliar vocabulary in the lesson.
LanguageTool: check a French draft
LanguageTool’s French checker looks for spelling, grammar and style issues. It is useful after you have written your own draft and want to review possible mistakes together.
Try this: accept corrections one at a time. For agreement or tense changes, explain the rule before moving on. A clean checker result is not proof that every sentence is correct.
BonPatron: learn from an error
BonPatron is designed around feedback for learners writing in French. Its explanations can help you notice patterns instead of repeatedly fixing the same kind of mistake.
Try this: keep a short correction log: your wording, the revised wording and the rule. Ask your teacher about feedback that conflicts with the structure being taught.
DeepL Write: improve phrasing
DeepL Write supports French and suggests wording improvements. Unlike translation between languages, its purpose is to revise text you are already writing.
Try this: compare the original with one suggested revision. Keep it only if the facts, emphasis and level of formality still fit. Avoid replacing your draft with vocabulary you cannot explain.
Reverso Context: compare expressions
Reverso Context shows expressions alongside translated examples. This can be useful when a dictionary definition does not tell you how a phrase is used.
Try this: inspect several examples, including the surrounding words. An expression from informal dialogue may not suit an academic paragraph, even when its translation looks right.
A French correction you can explain
Suppose you want to say: “If I had more time, I would read this book.” You are describing a hypothetical situation now.
Draft: Si j’aurais plus de temps, je lirai ce livre.
Correction: Si j’avais plus de temps, je lirais ce livre.
For this meaning, use si + imperfect in the condition and the conditional in the result. J’avais is the imperfect form needed here; je lirais expresses “I would read.” Je lirai is future tense, “I will read,” which does not express the intended hypothetical result.
This rule applies to this type of hypothetical sentence. Other conditions use other tense patterns. The University of Texas’s French guide to si clauses explains the distinctions.
The useful outcome is more than a corrected sentence: you should be able to write a new example using the same pattern.
A simple workflow for French homework
- Write your own first attempt. Use the vocabulary and grammar covered in class. Note the English meaning you intend if that helps you check it.
- Choose one kind of help. Translate for comprehension, check grammar for errors, or revise phrasing for clarity. Doing everything at once makes changes harder to judge.
- Check what changed. Verify who is doing what, when it happens, negatives, quantities and tu/vous. Smooth wording can conceal a changed meaning.
- Keep the rule and practise it. Save one useful correction and write another sentence without the tool. Follow your instructor’s rules for translation and AI assistance.
Apex Vision AI can help explain a question or correction shown on your screen. Include the whole sentence and the intended meaning, then compare its explanation with your course material. For the extension workflow, see the Apex Vision user guide.
“Check this French sentence for a hypothetical meaning. Give the smallest correction, explain each changed verb ending in English, and give me one similar sentence to try myself.”
For paraphrasing: DeepL Write is one option for revising French phrasing. Review changes sentence by sentence. Rewording a source does not make its ideas yours; keep any citations your assignment requires.
Frequently asked questions
What is a good free French grammar checker?
LanguageTool and BonPatron both offer free French checking. LanguageTool is useful for reviewing a draft; BonPatron focuses on learner feedback. Check the explanations and current limits. Neither can guarantee an error-free or factually correct assignment.
Is DeepL Write the same as DeepL Translator?
No. Translator works between languages; Write helps revise wording within a supported language, including French. Their paid plans are separate, so a Translator Pro subscription does not automatically provide Write Pro.
Can a grammar checker verify my translation?
It can flag some language errors, but grammatical French can still say the wrong thing. Compare the translation with the original for meaning, tense, tone, names and quantities. Use your course materials or ask your teacher when the meaning is uncertain.
How should I use these tools for French homework?
Follow your instructor’s rules, start with your own draft and ask for explanations you can understand. Keep a correction log and practise the same pattern in a new sentence. Submit only work you can explain yourself.
