I am taking the online course Introduction to Sanskrit offered by the Oxford Centre for Hindu Studies.  Here are a couple of tools that I use to augment my study:

Google Input Tools. (n.d.). Retrieved May 24, 2018, from https://www.google.com/inputtools/

Google Input Tools makes it easy to type in the language you choose. I installed language packs for Sanskrit and Bengali , which I used to create the graphics above.

Transliteration Tool. (n.d.). Retrieved May 24, 2018, from https://www.ashtangayoga.info/sanskrit/transliteration/transliteration-tool/

The Transliteration Tool enables you to enter text in Devanagari and transliterate it into IAST. I use it to cross-check my homework.

I think that if I look at these diagrams often enough, I'll learn the Bengali script ☺
