Search for an AI chatbot development company in India and you get two kinds of results: enterprise vendor pages that never mention scope or budget, and listicles padded with agencies that are not in India at all. Every company below is a real Indian vendor, or a global one with a staffed Indian office, described only from its own website, checked this week. Gleam is first, with a plain statement of where we fit and where we do not. After the shortlist: what a chatbot project actually includes, RAG versus scripted flows, handoff, WhatsApp versus web, and how to brief a vendor so quotes are comparable.
The shortlist at a glance
| Company | Focus | Best for |

| OrangeMantra (Gurugram, Noida) | Custom and GPT-powered bots for web, WhatsApp, Instagram and voice | Mid-size Indian businesses that want one vendor for every channel |
| LeewayHertz (Gurugram) | GPT-based and retrieval-based chatbots, dedicated teams | Companies extending their own product team with AI engineers |

Every AI chatbot development company on the list, in detail
1. Gleam Studio
We put ourselves first, so here is the honest framing. Gleam builds websites on Webflow and Next.js, and those builds increasingly ship with an AI assistant: a site-native chat that answers from your own pages and documents, qualifies a lead, books a call and writes the record into your CRM, with the automation flows behind it. We are not a chatbot-only vendor. If you need a WhatsApp support bot handling thousands of tickets a day in twelve languages, pick Haptik or Yellow.ai. If you want an AI chatbot for website conversion that knows your product and pricing, that is our lane.

2. Appinventiv
Appinventiv is the enterprise option, based in Noida with a second Indian office in Mohali. Its chatbot page lists consulting, conversation design, custom development, integration and support, with bot types from transactional and support bots to voice and multilingual assistants. The site claims 1,700+ staff including 200+ AI engineers, and names KFC and KPMG as clients. Its contact form's budget selector starts at "less than $50K", which signals the engagement size expected.
3. OrangeMantra
OrangeMantra operates from Gurugram and Noida, plus San Jose. Its service page covers custom AI chatbots, GPT-powered agents, voice bots and integration across websites, mobile apps, WhatsApp, Facebook, Instagram, Google Assistant and Alexa. The company claims 500+ experts and 150+ AI systems deployed. Best fit: a mid-size Indian business that wants one vendor for web, messaging and voice rather than stitching three tools together.
4. LeewayHertz
LeewayHertz lists a Gurugram office and is now part of The Hackett Group. The offering splits into GPT-based, retrieval-based, transactional and voice bots, with CRM, ERP and CMS integrations. Two engagement models are stated: a dedicated development team, or team extension where their engineers join yours. Shortlist them if you already have a product team and need AI capacity rather than a turnkey vendor.
5. TechAhead
TechAhead is headquartered in California with its Indian office in Noida. Its chatbot page is the most specific here about retrieval-augmented generation: pipeline design, vector database and guardrail configuration, fine-tuning on proprietary data, and agentic workflows. It cites AXA, American Express and Audi as clients. Consider them for a support deflection bot over a large document set, where you need a vendor who talks about hallucination rates, not just features.
6. Jio Haptik
Haptik is an Indian conversational AI company majority-owned by Jio Platforms since 2019, with a stated team of 200+. It is a platform, not a custom-code shop: pre-built agents for support, sales, booking and lead qualification on WhatsApp, RCS, Instagram, voice and web, with a choice of LLMs and RAG built in. Named customers include Swiggy, Zepto, Paytm and Sephora. If your volume is consumer-scale and WhatsApp-first, this beats any custom build on this list, ours included.
7. Yellow.ai
Yellow.ai was founded in 2016 and lists offices in Bengaluru, San Mateo, Singapore, Abu Dhabi, Malaysia and Indonesia. It sells an agentic AI platform: an agent builder, voice, chat and email automation, an agentic RAG knowledge base, and 15+ LLMs. The site claims 650+ brands. Like Haptik, it is a demo-led enterprise sale, so budget for platform fees plus implementation.
What an AI chatbot project actually includes
Quotes differ because vendors scope different things. Four decisions define the work.
The knowledge base
The bot is only as good as what it can read. Someone has to collect your pages, PDFs, pricing sheets and support macros, clean them, and decide what is out of bounds. Vendors skip this step in the demo, and it is why most bots answer badly.
RAG versus scripted flows
A scripted bot follows a decision tree you design: cheap, predictable, dumb outside the tree. A RAG bot (retrieval-augmented generation) pulls passages from your knowledge base and has an LLM write the answer, which handles open questions but needs guardrails, testing and a way to say "I don't know". Good builds mix both: scripted for bookings and forms, RAG for questions.
Human handoff
Decide up front where the bot stops: a WhatsApp agent, a ticket, a calendar booking or a sales email, with the transcript attached. A bot without a handoff path just generates angry customers faster.
WhatsApp versus web
In India, WhatsApp is where customers already are, but it runs on the WhatsApp Business Platform, which charges per conversation and needs template approval for outbound messages. A website assistant has no per-message fee and sees which page the visitor is on, so it wins for pre-sales. Support-heavy businesses want WhatsApp; lead-generation sites want web first.
Going web first for lead generation?
We will audit your site's forms and CRM handoff for free and show where leads drop off before any assistant gets built.
How to brief a chatbot development company in India
Send every vendor this brief:
- Top 20 questions your team actually gets, with the correct answers. This is the acceptance test.
- Sources the bot may use, and the ones it must never use.
- Channels in priority order: web, WhatsApp, app, voice.
- Actions beyond answering: book a call, create a lead, check an order.
- Handoff rules and who receives the transcript.
- Systems it must connect to, with the CRM named.
- Language list and whether Hinglish counts.
Ask for a fixed price on the first version plus a monthly figure for hosting, LLM usage and retraining; without the monthly figure the quote is incomplete. For a wider view of vendors, see our list of AI automation agencies in India; the future of web development covers why assistants are becoming part of the site rather than a bolted-on plugin.
Frequently asked questions
How much does AI chatbot development cost in India?
None of the companies above publish prices, so any figure in a blog is a guess. Cost is driven by channel count, RAG versus scripted flows, the systems it connects to, and languages. Appinventiv's contact form starts its budget selector below $50,000, which signals enterprise scale. Ask every vendor for a fixed build price plus a monthly running cost.
What is the difference between an AI chatbot and an AI agent?
A chatbot answers questions inside a conversation. An AI agent can also take actions: create a lead, check an order, book a slot, escalate a ticket. Platforms like Haptik and Yellow.ai market "agents" for this reason. For most Indian small and mid-size businesses, a chatbot with two or three well-tested actions beats a general agent that does anything badly.
Can an AI chatbot be added to an existing website?
Yes. The platforms above embed via a script tag, and a custom assistant can be added to a Webflow, WordPress or Next.js site without a rebuild. The real work is the knowledge base and integrations, not the widget. If a redesign is due anyway, building the assistant into the new site lets it read page context and pass leads straight into your forms and CRM.
Is a WhatsApp chatbot better than a website chatbot for Indian customers?
For support, usually yes: customers already have WhatsApp open and conversations persist. For pre-sales on a website, no: a web assistant sees the page the visitor is on, has no per-message fee, and hands off to a form or calendar in one step. Many businesses run both, with the web bot feeding WhatsApp for follow-up.
