AI chatbot developer in Kolkata
Kolkata runs on conversation, and much of it now happens on WhatsApp in Bengali, English and Hindi. A well-built chatbot answers the repeat questions so that your staff can handle the rest. I build AI chatbots grounded in your own information, with a human hand-off. I work remotely from India, test them before launch and promise no flawless answers.
Based in India and working remotely: no office in Kolkata, and video calls at times that suit you. Kolkata and I are both on UTC+5:30, so there is no time-zone difference and the working day overlaps in full. Many Kolkata offices, schools and clinics work Monday to Saturday, and some corporates Monday to Friday; calls are set around your pattern, including the long Durga Puja holiday period when many businesses slow down.
AI chatbot and RAG assistant development for Kolkata businesses
Schools, colleges and coaching centres around Salt Lake, Ballygunge and Park Street receive their questions in a short admission window: forms, fees, boards, documents and dates. An assistant in Bengali and English answers from one reviewed document, collects the parent's number and preferred call time, and sends the enquiry to the right counsellor. It never promises admission or results. Because many parents type Bengali words in Roman letters, I test the matching on that spelling, and I ask a native Bengali reader to approve the wording. On the busiest days the bot keeps answering from the same reviewed document, so the answer a parent gets at midnight matches the one given at noon.
Nursing homes and clinics need a modest, careful bot: doctor timings, location, what to carry, how to book, and a click-to-call button that stays visible. It should not interpret symptoms or reports, and it should pass anything urgent to a person with a phone number shown clearly. Medical advertising rules limit claims about cures, so the approved text is written with that in mind. Patient details fall under the DPDP Act 2023, so I keep collection to what the booking needs and agree retention with you. The same log lets the clinic see which questions come most often, which shows what its web pages should explain better.
Caterers, banquet halls and event planners face a seasonal pattern: Durga Puja, wedding months and festival weeks bring far more questions than the rest of the year. A bot answering about dates, capacity, menus, and how to hold a booking keeps those enquiries from piling up overnight. Traders in Burrabazar and manufacturers around Howrah can use a catalogue and RFQ assistant for buyers in the east and north-east. Salt Lake Sector V and New Town software teams ask for internal handbooks bots. Kolkata and I share UTC+5:30. I have no office in Kolkata; calls are by video unless you arrange to meet. Your team can read every conversation and mark wrong answers, which are then corrected in the source text.
Working with a remote specialist from Kolkata
- Time zone
- Kolkata and I are both on UTC+5:30, so there is no time-zone difference and the working day overlaps in full. Many Kolkata offices, schools and clinics work Monday to Saturday, and some corporates Monday to Friday; calls are set around your pattern, including the long Durga Puja holiday period when many businesses slow down.
- How projects there are usually paid
- Kolkata businesses mostly pay by NEFT, RTGS or cheque to a bank account, with UPI for smaller sums. Traders and companies expect a GST invoice with the supplier's GSTIN, and some deduct TDS, so I suggest settling invoicing details in the quote. Local currency: INR.
- Languages
- English, Bengali, Hindi
- Rules that apply
- The Digital Personal Data Protection Act, 2023 applies to student and patient data collected on enquiry forms, so purpose and consent should be stated clearly.

AI chatbot developer in Kolkata: questions
Yes. Bengali answers come from text a native reader approves, and I test the bot on real messages, including Bengali typed in Roman letters, before launch.
It answers dates, capacity and menu questions from current information, limits request bursts, and passes serious booking intent to your team with the details already collected.
No. It covers timings, doctors, location and booking, and shows a phone number for anything urgent or clinical so a person takes over.
Yes. It answers from your product sheet, asks for the buyer's city and quantity, and sends a tidy enquiry to your sales person, leaving price and credit terms to a person.
RAG means the assistant searches your own documents first and then writes an answer from what it found. That keeps replies tied to your information, makes updates a matter of changing documents and lets it say it does not know.
Yes, any language-model system can. I reduce the risk with grounding in your content, limits on what it may say, testing against difficult questions, human hand-off and log review, but I cannot promise it will never be wrong.
Yes. Bengali is my native language, along with fluent Hindi and professional English, so I can discuss the project and write or edit Bengali page and ad copy myself.
