You can't type Hindi straight into WhatsApp unless your phone already has a Hindi keyboard installed — WhatsApp just borrows whatever keyboard your phone gives it. The fast way around that, without changing a single phone setting: type your message on kactyl.com/hindi/, copy it, and paste it into the chat.
Hinglish vs Real Hindi — What to Actually Send
Most Hindi WhatsApp messages are “Hinglish” — Hindi typed in Latin letters (“kaise ho” instead of कैसे हो). It’s fast and everyone reads it, but it’s ambiguous (is “koi” कोई or “coy”?), looks casual, and older relatives usually prefer the real script. Kactyl types proper देवनागरी, so you can send कैसे हो for festival greetings, elders, and anything that should feel sincere.
Why Some Conjuncts Look Broken on Older Phones
Hindi stacks consonants into conjuncts — क्ष, त्र, श्र, द्ध. On older Android phones or an outdated WhatsApp, the shaping engine can show a broken cluster or a dotted circle (◌) where a vowel mark failed to attach. Type in the Kactyl editor to preview exactly how it reads; a receiver on a modern phone sees it correctly.
Matras — the Vowel Signs That Reorder Themselves
In Devanagari, vowels attach as marks (मात्रा) around a consonant, and some are written before the letter even though they’re read after — कि (ki) shows the sign on the left. On a phone you tap consonant then vowel and the script reorders on its own; that’s normal, not a bug.
