TwingBot understands Bangla, Banglish (Bangla typed in English letters), English and mixed messages, and replies in the same language the customer used -- with the tone of a real shopkeeper rather than a robot.
There is no language setting to choose. A message like 'dam koto?' or 'ei ta ki stock ache?' is understood and answered in the same style. Bangla script, Banglish and English mixed in one sentence all work.
COD totals with delivery charge, fake order checks before courier submission, and courier-ready order preparation for the local delivery workflow that F-commerce sellers actually use.
The same account also answers Hindi, Urdu, Arabic, Chinese, Spanish and more, so a page running international ads is covered without extra setup.
