Frequently asked questions

How long does it take to build an AI chatbot?

A focused pilot (1 chatbot, 1 channel, RAG on 1 knowledge source) ships in 3–4 weeks. A full production rollout with multi-channel deployment, CRM integration, and analytics typically takes 5–7 weeks end-to-end.

Which AI model do you use — GPT-4o, Claude, Gemini, or open-source?

We're model-agnostic and choose the best for each use case based on accuracy, latency, and cost. Often we route: easy questions to GPT-4o-mini / Claude Haiku, complex reasoning to GPT-4o / Claude 4. For private/regulated data we use Azure OpenAI, AWS Bedrock, or Vertex AI.

How accurate is the chatbot?

We measure accuracy formally — typical RAG chatbots reach 85–95% answer correctness on real customer questions after our tuning phase, with citation links so the user can verify. We commit to an accuracy floor in the SOW.

How do you prevent hallucination?

Retrieval-grounded answers (RAG), citation-required system prompts, structured output where applicable, automated fact-check passes for high-stakes flows, and a low-confidence fallback that hands off to a human instead of guessing.

Can you integrate the chatbot with our existing CRM and helpdesk?

Yes. We routinely integrate with HubSpot, Salesforce, Zoho CRM, Odoo CRM, Pipedrive, Zendesk, Intercom, Freshdesk, and custom systems. The chatbot creates tickets, logs conversations, and updates lead records automatically.

What does it cost?

Pilot chatbots typically land between ₹1.5L–₹4L ($1.8K–$5K) setup plus ₹15K–₹50K/month ($200–$600) covering hosting, monitoring, and tuning. Full production rollouts with multi-channel deployment and CRM integration range from ₹4L–₹15L ($5K–$18K).

Can the chatbot speak multiple languages?

Yes. GPT-4o and Claude 4 natively support 95+ languages with strong quality. We localise the knowledge base, prompts, and UI for the languages your customers actually use, with per-language accuracy tracking.

Do you offer a managed / SLA-backed support plan?

Yes — our Managed AI Bot retainer covers monthly prompt tuning, model upgrades (every time OpenAI or Anthropic ships a new model), cost optimisation, observability, and a quarterly business review. SLA-backed response times for incidents.
