Why Coderlab

Why we are different from other software companies

We’re not the cheapest. Not the oldest. But we’re the smartest choice for businesses that want AI-powered solutions delivered with personal attention at fair prices.

3–5× Faster development

AI-First, From Day One

While traditional IT firms added AI as an afterthought, Coderlab was built from the ground up with AI-first principles. Every project leverages modern tools like Cursor, Claude Code, and GPT-5 — making your software 3-5x faster to build with built-in intelligent features.

7-day MVP delivery standard
40–70% Lower cost vs competitors

Chatbot FAQ

Frequently asked chatbot questions

The 8 questions every business asks us before going live with their first AI chatbot.

How much does an AI chatbot cost?

A production-ready AI chatbot at Coderlab starts at ₹15,000 / $500 USD for a single-channel MVP (WhatsApp or web or app). Multi-channel + RAG + CRM integration typically lands between ₹75,000 – ₹2,50,000. Enterprise voice + multilingual + on-prem deployment is custom-quoted. We give a fixed quote in the first call.

How long does it take to build and launch?

Most chatbots ship in 7–21 days. Our AI-first development workflow (Cursor + Claude pair-programming) compresses what used to take 3 months into 3 weeks. Voice agents and multi-language deployments may need 4–6 weeks.

Which channels can the chatbot run on?

Web (chat widget or full-page), iOS & Android apps (native SDK or webview), WhatsApp Business API (cloud or on-prem BSP), Facebook Messenger, Telegram, Slack, MS Teams, Instagram DMs, and voice (phone via Twilio/Plivo, smart speakers, in-car HUDs). One bot brain, all channels.

Do you train the bot on my company's data?

Yes — every Coderlab chatbot is RAG-trained on your private documents (PDFs, Notion, Confluence, Google Drive, support tickets, product catalog). We auto-sync nightly so your bot is always current. Your data stays in your VPC if you require it.

Which languages do your chatbots support?

All 22 official Indian languages + 90+ global languages out of the box. We use a mix of GPT-5, Claude, Gemini for text and ElevenLabs / Whisper / Sarvam for voice. Hindi, Hinglish, Tamil, Telugu, Marathi, Bengali and Punjabi are battle-tested.

Where is the chatbot hosted? Is my data secure?

Default hosting is AWS Mumbai region (DPDP / data-residency compliant). For HIPAA / regulated workloads we deploy on-prem or in your private cloud. End-to-end encryption, role-based access control, PII redaction, and SOC-2 grade logging are standard.

How accurate is the chatbot? Can it handle complex queries?

Our chatbots achieve 95%+ intent accuracy after the first week of fine-tuning on your real conversations. For ambiguous or out-of-scope queries, the bot gracefully hands off to a human with the full conversation context — never starting from scratch.

Who owns the chatbot & the trained model?

You do — 100%. Source code, training data, fine-tuned model weights, conversation logs and the running infrastructure are all yours. We sign an IP transfer + NDA before kickoff. No vendor lock-in.
