Yes. Paste an essay answer, paragraph, or full composition and review each correction with its explanation. The explanations describe the grammar rule involved, so it doubles as a learning tool for school and college Tamil.

Yes. Colloquial forms like வர்றேன் or போறீங்க are recognised as valid spoken Tamil rather than flagged as errors, and the spoken-to-formal workflow can rewrite them into formal written Tamil (வருகிறேன், செல்கிறீர்கள்) when you need a formal register.

Yes. Case-marker (வேற்றுமை உருபு) issues — such as a missing dative க்கு or accusative ஐ — and verb errors like wrong tense or subject–verb agreement are core checks, each shown with an explanation.

Yes. Commonly confused Tamil letters — ல/ள/ழ, ண/ந/ன, and ர/ற — are among the most frequent spelling mistakes, and the checker reviews them using the whole word and sentence as context.

TamilGrammar.in is designed specifically around Tamil writing correction. It focuses on targeted grammar and spelling corrections and explains the changes so writers can review them. It also includes Tamil-specific tools such as Tanglish typing, OCR, and spoken-to-formal conversion.
