Grammar Checker for European Languages

An online tool that checks grammar and punctuation for languages like French, German, and Spanish.

The problem

Many people make grammar and comma mistakes in foreign languages. European rules are tricky and easy to get wrong. Most checkers focus on English, leaving others with few good options.

The solution

The tool checks text against each language's own rules. It flags errors and suggests fixes as you type. It also explains the rule so users learn over time.

Who it's for

Language learners, students, and workers writing in Europe. Schools and firms pay for group plans.

How it makes money

Monthly subscription. Group plans for schools and businesses.

Market note

Language learning demand is high, but non-English checkers are scarce.

How to validate it

1Ask learners and teachers about their writing problems.
2Build a basic checker and give it to beta testers.
3Study the results and improve before a full launch.
