An open AI platform that listens to your Tamil, understands every accent — from Chennai streets to Sri Lankan shores — and gently guides children back to their mother tongue.
யாதும் ஊரே யாவரும் கேளிர்— புறநானூறு · Purananuru 192 | "Every land is my home; all people are my kin."
Tamil is one of the world's oldest living classical languages — yet millions of children today grow up unable to read, write, or speak it fluently. English-medium schooling, migration, and digital gaps have eroded what 2,000 years of literature built.
Thamizharivu is our answer. We build open AI tools that listen to Tamil spoken in every accent, correct gently without shaming, and celebrate the diversity of our dialects — from the fast rhythm of Chennai to the melodic cadence of Jaffna.
We do not impose a single "correct" Tamil. We honour every voice — Madurai, Coimbatore, Sri Lankan, Malaysian, diaspora — while helping children write beautifully and speak clearly.
AI that hears the child's voice before it speaks. Accent-aware speech recognition trained on regional Tamil audio datasets.
No red marks. No shame. Visual cues in Tamil guide the learner toward correct spelling and grammar without discouragement.
Open datasets contributed by communities, annotated for accent and age, to train better models for every generation.
Tamil belongs to all who speak it — in Tamil Nadu, Sri Lanka, Singapore, Malaysia, and the global diaspora.
Learn to read, write, and speak Tamil — from the first stroke of அ to composing full sentences. All lessons are in Tamil-first, with English support available.
Learn all 247 Tamil letters — 12 vowels (உயிர்), 18 consonants (மெய்), and 216 compound letters (உயிர்மெய்). Interactive stroke-order animations.
Speak a word aloud. Our AI compares your audio to reference phonemes and gives instant feedback — where your tongue should be, how long to hold the vowel.
Tamil grammar — எழுத்திலக்கணம் (phonology), சொல்லிலக்கணம் (morphology), and பொருளிலக்கணம் (semantics) — explained simply with real examples.
Public domain folk tales, Aesop in Tamil, and classic Sangam poems — read aloud, annotated, and searchable. Learn vocabulary through context.
Type or paste any Tamil text. Our fine-tuned language model highlights errors, explains the correct spelling, and shows the grammatical rule — in Tamil.
Earn stars for daily practice, unlock badges for mastering letter groups, and track your streak on a Tamil-language progress board. Learning feels like play.
There is no single "pure" Tamil — there is the Tamil of your street, your district, your island, your diaspora. Our AI recognises and honours every variation, never forcing one accent as the only standard.
Urban rhythm, code-mixing with English, the baseline dialect for most media.
Rich retroflex sounds, classical vocabulary preserved in everyday speech.
Softer consonants, distinct intonation, influenced by Kannada border regions.
Preserves archaic grammatical forms lost in mainland Tamil; unique phonology.
Influenced by Malay and English, distinct musical quality, plantation vocabulary.
