Semantic Search & Document Intelligence
We build search systems that understand meaning, not just keywords. Using embeddings and vector databases, we enable your users to find relevant documents, answers, and insights from large text collections without exact keyword matching.
LLM Integration & Fine-Tuning
We integrate large language models into your applications through APIs, custom fine-tuning, or private deployments. We handle model selection, prompt engineering, RAG architecture, and cost optimization for production reliability.
Text Classification & Entity Extraction
We develop NLP pipelines that automatically categorize documents, extract named entities, identify sentiment, and flag critical information. This turns unstructured text into structured data for analytics and automation.
Document Chatbots & Knowledge Assistants
We build conversational interfaces that answer questions from your documents, manuals, and knowledge bases. Using RAG with source attribution, every answer is grounded in your approved content.
Text Summarization & Generation
We implement abstractive and extractive summarization for long documents, reports, and conversations. We also build controlled text generation systems for templates, descriptions, and structured outputs.
Multilingual NLP
We develop NLP solutions for German, Italian, Polish, English, and mixed-language content. We handle tokenization, entity recognition, and semantic matching across languages with regional business terminology.
Business Problems Our NLP Development Services Solve
We have thousands of documents but no way to search them effectively.
We build semantic search systems using embeddings and vector databases. Users find relevant content by asking natural questions, not by guessing keywords. We implement reranking, filtering, and faceted search for precision at scale.
We want to integrate LLMs but don't know where to start.
Our LLM integration services evaluate your use case, select the appropriate model (OpenAI, Claude, Llama, Mistral), and design the architecture: API, fine-tuning, or RAG. We handle prompt engineering, fall-back logic, and production monitoring so your LLM solution is reliable from day one.
Our team spends hours reading and categorizing documents.
We automate text classification, entity extraction, and sentiment analysis through custom NLP pipelines. Documents are automatically tagged, routed, and summarized — reducing manual review time while maintaining accuracy.
Customers ask the same questions, but our knowledge base is hard to navigate.
We build document chatbots that answer questions directly from your documentation. Users ask natural questions; the chatbot retrieves relevant passages, synthesizes answers, and provides source citations. No more frustrated customers lost in documentation hierarchies.
We need to analyze customer feedback, support tickets, or social media at scale.
We develop sentiment analysis, topic modeling, and intent detection systems that process thousands of text inputs automatically. You identify trends, flag issues, and prioritize responses based on data, not intuition.

Semantic Search with Embeddings
We implement vector search using embeddings from models like OpenAI, BERT, or domain-specific transformers. Documents are converted to vector representations that capture meaning, enabling similarity search, clustering, and recommendation across large text collections.
LLM Integration Architecture
We design LLM integration patterns that match your reliability, cost, and privacy requirements. Options include API-based access, fine-tuned models on your data, or private deployments using open-source models. We implement caching, rate limiting, and fallback chains for production stability.
Entity Extraction & Intent Detection
We build NLP pipelines that identify people, organizations, dates, and custom entities in your documents. We also detect user intent from queries, support tickets, and chat messages — enabling automated routing and response generation.
Knowledge Base & Semantic Matching
We connect NLP systems to your knowledge base through vector databases and graph structures. Semantic matching finds related concepts even when terminology differs, improving search recall and recommendation accuracy.
Text Summarization Pipelines
We implement extractive summarization (selecting key sentences) and abstractive summarization (generating concise paraphrases) for documents, conversations, and reports. Summaries maintain factual accuracy while reducing reading time.
Multilingual & Cross-Language Processing
We handle German, Italian, Polish, English, and mixed-language content with language detection, cross-lingual embeddings, and translation-aware processing. Regional business terminology and industry jargon are incorporated into custom models.
Example NLP & LLM Use Cases We Can Build
Legal Document Semantic Search
A Swiss law firm needs to search across thousands of contracts, court decisions, and legal opinions using natural language queries. We would build a semantic search system with embeddings, metadata filtering by jurisdiction and date, and source attribution for every result. Lawyers find relevant precedents faster without relying on exact keyword matches.
Multilingual Customer Support Classification
An Austrian e-commerce company receives support tickets in German, Italian, and English. We would develop an NLP pipeline that detects language, classifies intent (refund, technical issue, product question), extracts order numbers, and automatically routes tickets to the right team, reducing response time and improving routing accuracy.
Manufacturing Document Intelligence
A Polish industrial company has decades of maintenance manuals, safety protocols, and technical specifications in PDF format. We would build a document chatbot that answers technician questions, retrieves relevant procedures, and provides step-by-step guidance from approved documentation with full audit trails for compliance.
Financial Report Summarization
An Italian investment firm needs to quickly analyze earnings reports, market commentary, and regulatory filings. We would implement text summarization to extract key metrics, risk factors, and strategic updates from long documents, enabling analysts to review more reports in less time while maintaining consistent coverage.

Frequently Asked Questions About NLP & LLM Development
LLM integration is the process of connecting large language models to your existing software, data, and workflows. This includes selecting the appropriate model, designing prompt templates, implementing retrieval-augmented generation (RAG) with your knowledge base, and deploying to production with monitoring and cost controls. Proper LLM integration ensures the AI answers from your approved content, not generic training data, and operates reliably under real user load.
NLP helps business software understand, process, and generate human language. Applications include semantic search across documents, automatic classification of support tickets, entity extraction from contracts, sentiment analysis of customer feedback, and conversational interfaces for knowledge bases. NLP turns unstructured text emails, documents, and chat logs into structured data that drives automation and analytics.
Yes. We build semantic search systems that find documents by meaning rather than keywords, using embeddings and vector databases. We also develop document chatbots that answer questions from your knowledge base with source attribution. Both systems use RAG to ground answers in your approved content, reducing the risk of hallucinations and improving user trust.
We integrate OpenAI GPT, Anthropic Claude, Meta Llama, Mistral, and custom transformer models. For NLP pipelines, we use BERT, spaCy, Hugging Face transformers, and domain-specific models. We select the model based on your accuracy needs, language requirements, cost constraints, and data privacy policies. For sensitive data, we recommend private deployments or models hosted in Europe.
A focused NLP MVP with semantic search or document chatbot typically takes 2.5 – 3 months. Complex multilingual systems, large-scale enterprise integrations, or custom model training may take 4–5 months. We provide detailed timelines after the discovery phase.
The cost of NLP development services depends on use case complexity, data volume, language support, integration requirements, and ongoing hosting needs. After discovery, we provide a clear estimate with scope, timeline, and delivery phases. We also model operational costs (embedding generation, vector storage, LLM API usage) for full cost visibility.
Yes. We develop multilingual NLP solutions that automatically detect language, process mixed-language content, and perform cross-lingual semantic search.
