Varta Keyboard

Varta Keyboard enables typing in multiple Indian languages directly from your browser using a standard QWERTY keyboard. You can also use Voice typing with Varta Keyboard.
How to use Varta:
Varta Keyboard does not have separate keys for vowel signs or modifiers in Indian languages. Instead, it automatically generates the appropriate modifier based on the combination of consonants and vowels you type. The online virtual keyboard can be turned on to show on-screen key layout.
To use this extension, the system's keyboard language must be set to English.
For example, typing 'र्' and 'आ' would generate letter 'रा' in Hindi, Marathi and Sanskrit. Similarly typing 'ವ್' and ' ಾ' would generate Kannada letter 'ವಾ', 'ക്' and 'ഉ' would generate Malayalam letter 'കു', typing 'க்' and 'ஓ' would generate Tamil letter 'கோ', typing 'ర ' and 'ఆ'would generate Telugu letter 'రా' .
In Malayalam, chillaksharams and some archiac characters can be accessed in 'Alt + Shift' (see a screenshot above). For example, to type a chillaksharam, press Alt and Shift together followed by the desired letter.
Currently supporting Hindi, Kannada, Malayalam, Marathi, Sanskrit, Tamil and Telugu along with English, Varta Keyboard will add more Indian languages in future updates.
