NLP & Chatbots

AI / ML Development Services

We build language AI systems that understand context, intent, and nuance not just keywords. From chatbots to enterprise NLP pipelines, we build for production reliability.

What We Do

NLP allows organisations to automate tasks that previously required human reading and judgement classifying documents, extracting information, detecting sentiment, routing queries, and generating coherent responses. Conversational AI and chatbots sit at the most visible end of NLP done well they reduce support costs and improve response times; done poorly they frustrate users and damage the brand.

We cover the full NLP spectrum text classification, named entity recognition, intent detection, sentiment analysis, semantic search, document intelligence, RAG systems, and full chatbot development. Every system is designed for your specific use case and data, not from a generic template.

Our NLP & Chatbot Services

AI Chatbot Development

Conversational chatbots that handle customer queries, automate support, generate leads, and assist internal teams using NLP to understand intent, maintain context, handle ambiguity, and escalate to humans when needed.

Customer support chatbots with intent classification and context management

Lead qualification and sales assistant chatbots

HR and internal helpdesk automation

Multi-turn dialogue with graceful escalation handling

Multilingual English, Hindi, Gujarati, and other Indian languages

Natural Language Processing Systems

NLP pipelines that extract structured meaning from unstructured text reducing manual reading and classification across emails, support tickets, forms, reviews, and reports.

Text classification for document routing and support triage

Named entity recognition names, dates, locations, domain-specific terms

Sentiment analysis for customer feedback and social media monitoring

Intent detection and topic modelling for knowledge management

LLM Integration & RAG Systems

We integrate GPT-4, Claude, Gemini, and open-source LLMs into your applications with prompt engineering, context management, output validation, and RAG systems that ground responses in your own data.

RAG systems for knowledge-grounded LLM responses

Document summarisation and intelligent report generation

Semantic search powered by vector embeddings

Secure, scalable LLM infrastructure and API cost management

Document Intelligence & Information Extraction

Automated extraction of structured data from invoices, contracts, forms, medical records, and regulatory documents feeding results directly into downstream systems without manual data entry.

Invoice and purchase order extraction and validation

Contract clause identification and obligation extraction

Medical record parsing and clinical data extraction

OCR integration for scanned document processing

Semantic Search

Search that understands meaning, not just keywords surfacing relevant results even when exact words don’t match. Particularly valuable for knowledge bases, document libraries, and product catalogues.

Embedding-based semantic search over document repositories

Product and catalogue search with intent understanding

Hybrid semantic and keyword search for precision

Integration with Pinecone, FAISS, Weaviate, and Elasticsearch

Sentiment Analysis & Opinion Mining

Process customer feedback, reviews, and support tickets at scale identifying sentiment, pain points, and emerging trends that would take a human analyst weeks to surface manually.

Customer review and feedback sentiment classification

Support ticket scoring for priority routing

Brand sentiment tracking across social media

Aspect-based analysis for granular product feedback

Core Capabilities

Intent Classification & Entity Recognition

The foundation of every reliable chatbot identifying what users want even when phrased multiple ways, and extracting the specific values that matter.

Transformer-Based NLP Models

BERT, RoBERTa, DistilBERT, and domain-specific transformer variants selected based on accuracy requirements, latency constraints, and data availability.

Large Language Models

GPT-4, Claude, Gemini, LLaMA 3, and Mistral with LangChain and LlamaIndex for RAG systems, prompt engineering, and context management.

Conversational AI & Dialogue Management

Multi-turn dialogue systems that maintain context, handle topic changes, manage ambiguity, and route to human agents appropriately.

Multilingual NLP

English, Hindi, Gujarati, and other Indian regional languages using multilingual transformer models and language-specific datasets.

MLOps for NLP

Model versioning, automated retraining, performance monitoring with drift detection keeping production NLP systems accurate over time.

How We Work

We define conversation flows, NLP requirements, and integration points before any development begins.

Chat logs, FAQs, domain documents annotated and prepared with data privacy compliance throughout.

Intent classifiers, entity extractors, and response generators built and validated iteratively on your domain data.

Multi-turn flows, fallback handling, escalation paths designed to match your brand voice and business rules.

Deployed into your website, app, CRM, or internal tools via APIs on AWS, GCP, Azure, or on-premise.

Performance monitoring, retraining on new data, quarterly reviews keeping accuracy strong over time.

Why Web Chip Armor

Here is what genuinely distinguishes our React team.

We build for your data and use case, not a generic template

Every chatbot and NLP system is trained on your domain data and designed around your specific workflows. We don’t apply a standard template and call it custom.

Multilingual by design for the Indian market

English, Hindi, and Gujarati support built in not added as an afterthought. Essential for businesses serving India’s linguistically diverse customer base.

Honest about what the data supports

We assess your training data at the outset and tell you what accuracy is achievable before committing to a build. No inflated accuracy claims.

Integration with existing systems

CRM, ERP, helpdesk, and web applications our NLP and chatbot systems connect to your existing infrastructure via APIs and standard connectors.

Production-grade, not prototype

Systems that handle real usage volumes, edge cases, and off-topic inputs reliably. We test for adversarial and out-of-scope inputs before every deployment.

Frequently Asked Questions

How long does it take to build an NLP chatbot?

A focused customer support chatbot typically takes six to ten weeks. Advanced LLM-powered assistants with custom training and integrations take two to four months. We give you a realistic timeline after a discovery session.

What data is needed to train an NLP model?

Historical conversation logs, FAQs, or domain documents relevant to your use case. A minimum of 500 to 1,000 labelled examples per intent yields reliable results. We assist with data collection, annotation, and preparation throughout.

Does the chatbot support Gujarati and Hindi?

Yes. Multilingual support across English, Hindi, and Gujarati is built in by design not added as an optional extra. We build and validate in each target language, not just the dominant one.

Can it integrate with our existing CRM or helpdesk?

Yes. Our chatbots and NLP systems are API-first and integrate with Salesforce, Zoho, Freshdesk, Zendesk, HubSpot, and any system with a REST or webhook interface.

How do you handle data privacy and security?

End-to-end encryption, role-based access control, and compliance with India’s DPDP Act and GDPR where applicable. All conversation data is handled under your data governance policies. NDAs are signed before any project begins.

What does it cost?

Simple FAQ chatbots start from Rs. 40,000. Custom NLP pipelines and LLM-powered enterprise assistants range from Rs. 1,50,000 to Rs. 10,00,000+ depending on complexity and integrations. We provide a fixed-price estimate after a discovery session.
