Banglish has no official spelling, so everyone writes the same word differently. Shuddho reads what you meant, not what you typed.
It fixes, it doesn't translate
Your text stays Banglish. Bengali is only the ruler it measures against — tap বাংলা to see it.
Typos are fine
Sound-alike letters are treated as the same letter, so achan, asen and achhen all land on achen.
It fixes as you type
Spellings it is sure of are corrected the moment you finish the word. Tap a corrected word to put yours back — and Shuddho won't touch that word again. Anything it isn't sure of stays underlined and waits for you.
No account, no upload
Common words are corrected on your phone, offline. Only rare words are sent for a deep check, and nothing is stored.
