    Types of AI Chatbots — and Which One You Actually Need

    "Chatbot" covers four very different builds. Picking the right one decides both your cost and your results.

    Rule-based / flow bots

    Fixed menus and decision trees. Cheap and predictable, but they break the moment a customer phrases something unexpectedly.

    Best for: Simple FAQs, order status lookups, appointment menus.

    AI chatbots with RAG

    An LLM answers using your own documents through Retrieval-Augmented Generation, so replies stay grounded in your real content.

    Best for: Support, product knowledge, policy and documentation queries.

    Agentic bots (function calling)

    The bot does not just answer — it books, updates, refunds or fetches live data by calling your APIs and CRM.

    Best for: Bookings, order actions, CRM writes, ticket creation.

    Voice AI agents

    Speech-to-text, an LLM brain and natural voice output over a phone line, in Hindi and English.

    Best for: Inbound support calls, outbound lead qualification, reminders.

    What Drives AI Chatbot Development Cost

    Six factors explain almost every difference between a ₹25,000 bot and a ₹2,00,000 one.

    Knowledge base size

    Ingesting 50 pages is quick. Thousands of PDFs, tickets and product records need cleaning, chunking and evaluation — the biggest single driver of scope.

    Number of channels

    One website widget is the baseline. Each extra channel — WhatsApp, Instagram, Slack, phone — adds integration, testing and approval work.

    Actions vs answers

    Answering is far cheaper than acting. Every write action (book, refund, update CRM) needs API work, permissions and guardrails.

    Accuracy target

    Getting from "usually right" to consistently accurate takes evaluation sets, prompt iteration and retrieval tuning. Higher bars need more cycles.

    Data privacy requirements

    Self-hosted models, private vector databases and audit logs cost more than managed APIs, but are needed in regulated sectors.

    Ongoing usage

    LLM tokens are billed per message. Model choice and prompt size decide whether monthly running cost is a few hundred or several thousand rupees.

    What Clients Say About Our Chatbot Development

    Feedback from founders and engineering leaders after their bots went live.

    "Socilet built our WhatsApp bot in under 3 weeks and it now handles the majority of our support load. The zero-advance model made it a no-brainer — we only paid after seeing it work on real customer chats."

    Ananya R.
    Founder · D2C Skincare Brand
    "We evaluated 4 chatbot vendors. Socilet was the only one who trained the bot on our actual PDFs and Notion, not a scripted flow. Our demo bookings tripled in the first month."

    AI Chatbot Development — FAQs

    Pricing, LLM choice, WhatsApp integration, timelines and data privacy — everything you need to know.

    How much does AI chatbot development cost in India?

    Our AI chatbot development pricing starts at ₹24,999 (~$299) for a website widget bot trained on up to 100 pages, ₹59,999 (~$719) for a full Business bot with WhatsApp + CRM + analytics, and custom (from ~$1,999) for voice AI or enterprise deployments. All zero advance — pay after approval.

    How long does it take to build an AI chatbot?

    Starter bots ship in 2 weeks. Business bots (WhatsApp + CRM + analytics) take 3–4 weeks. Voice AI or enterprise deployments take 6–10 weeks. You see working demos every week.

    Which LLM do you use — GPT-4, Gemini or Claude?

    We're model-agnostic. We benchmark GPT-4o, Gemini 2.5 Pro/Flash, and Claude Sonnet on your actual queries and pick the best cost-to-accuracy trade-off. We can also deploy open-source Llama 3 or Mistral on your own servers if you need full data privacy.

    Can the chatbot work on WhatsApp?

    Yes. We deploy on the official WhatsApp Business API (via Meta / Gupshup / Twilio) so your customers chat on WhatsApp while the same bot brain powers your website widget and Slack. Full multi-channel with unified conversation history.

    Will the bot be trained on my company data?

    Yes. We ingest your website, PDFs, Notion, Google Drive, support tickets and any API into a vector database (pgvector or Pinecone), then use Retrieval-Augmented Generation (RAG) so answers are grounded in your real content — not the LLM's general knowledge.

    Is my data safe? Where is it stored?

    By default, your knowledge base lives in your own Supabase / Postgres instance. We support GDPR and India's DPDP Act, sign an NDA + DPA, and can deploy fully self-hosted (private LLM + private vector DB) for regulated industries.

    Can the bot escalate to a human agent?

    Yes — human handoff is built in. When the bot is unsure or the user asks, the chat routes to a live agent on WhatsApp, email, or your existing helpdesk (Freshdesk, Zoho Desk, Intercom, etc.) with full conversation context.

    Do you offer ongoing chatbot maintenance?

    Yes. After launch, most clients take a monthly retainer (₹9,999–₹29,999) for weekly retraining on new content, adding intents, cost optimization, and monitoring. Optional — you can also self-manage via the admin dashboard we ship.

    Why choose Socilet over a no-code platform like Landbot or ManyChat?

    No-code tools work for simple FAQ flows. For anything involving real product knowledge, custom logic, CRM writes, or voice AI, you need a proper LLM stack with RAG, guardrails, and function-calling. That's what we build — and because it's custom, you own the code, the data, and the bot forever.

    Do you build voice AI agents (phone bots)?

    Yes. We build inbound and outbound voice AI agents on Twilio + ElevenLabs (or OpenAI Realtime API) in Hindi and English — for appointment booking, lead qualification, and Tier-1 support calls.
