i have been working on a small ai tool for tamil grammar and spelling correction. we already built something similar for hindi, and one thing i noticed is that regional language users have a real problem but not many polished tools are made for them. right now i am not focusing on big features. first i am trying to understand who will actually use it, like students, writers, teachers, book publishers, and content creators. one challenge is tamil has many writing styles, so simple correction is not always enough. context matters a lot. my current plan is to collect real examples from tamil books, publisher content, and user-written text, then slowly improve the correction quality. has anyone here built for non-english users before? how did you validate the first users before building too much?

I have been thinking about small business software ideas recently. many local businesses do not need a big platform, they just need one small tool that saves them time every week. but i am confused about where the line is between a custom tool and something that can become a micro saas. for people who have tried building micro saas, how do you decide if a problem is common enough to build for more than one customer? do you validate by talking to business owners, checking search volume, reading reddit problems, or building a small version first?
