Multilingual AI applications — MVP in 4 to 6 weeks
Multilingual AI applications built by developers and linguists together: MVP within 4 to 6 weeks, LLM-agnostic (DeepL Pro, OpenAI, Anthropic and Google plus open-source models) and production-ready from day one.
Multilingual AI applications built from linguistic and technical insight: chatbots, translation APIs, NLP-driven search and document processing — MVP in 4 to 6 weeks, LLM-agnostic and production-ready from day one.
What sets our approach apart is the combination of technical engineering talent and native linguistic expertise. Where purely technical teams treat multilingual reach as a configuration question, we also understand the linguistic, cultural and quality dimensions that decide whether an AI language application genuinely works for end users — across 20+ markets.
From core EU languages to low-resource markets with custom fine-tuning on your domain data.
We analyse your business case, define functional and non-functional requirements and decide which language-AI technology fits best: LLM choice, translation API, NLP framework, ASR or TTS.
Technical design of your multilingual AI application: LLM choice, API integrations, data flow, caching, scalability, privacy and GDPR compliance per market.
In two-week sprints we build your application iteratively. After every sprint you receive a working product for feedback — no waiting until the end of a multi-month build.
Native language specialists test the application in every required language for accuracy, cultural fit and user experience. Developer testing alone is not enough for multilingual AI.
Working MVP within 4 to 6 weeks. From there we guide further development based on real user feedback — including hosting, monitoring and ongoing maintenance.
A chatbot running the same scripts across 8 markets without native reviewers fails on nuance and trust. An AI translation API without linguistic QA produces hallucinations at scale. We work as one team — developers, LLM specialists and native language experts — so your AI product not only runs, but reads right.
Where technical teams treat multilingual reach as configuration, we build it from linguistics — with developers, native experts and LLM specialists in one team.
Our applications are designed to be multilingual from the architecture up — not as an afterthought, but as core functionality. Adding a 20th language does not require a refactor.
With Agile development and state-of-the-art AI components we deliver a working MVP in 4 to 6 weeks. Real user feedback gathered quickly, instead of months of stealth build.
We work with DeepL Pro, OpenAI, Anthropic and Google plus open-source models, NLP frameworks and translation APIs. Model choice driven by use case, not by hype.
Guidance from idea through prototype to production-grade application — including hosting in a customer-configured cloud environment, monitoring, logging and ongoing maintenance.
From model choice to live monitoring — the foundation of AI applications that real users rely on.
From chatbot deployments to document extraction and multilingual search — AI applications running in production.
Finance · Chatbot A bank launched a customer-service chatbot across 8 markets. LLM with custom domain knowledge, GDPR-aligned hosting (datacenter configurable on request) and fall-back to human agents. MVP in 5 weeks; high self-service rate achieved.
Pharma · NLP A pharmaceutical company automated patient-record extraction from scanned documents in 14 languages. Custom NLP pipeline with OCR and a native human QA layer. Throughput considerably higher than manual.
E-commerce · NLP A marketplace built an NLP-driven search engine for 20 markets. Semantic search, query-intent detection per language and regional catalogue matching. Measurable improvement in search-to-buy.
From customer-service chatbots to NLP search and multilingual e-commerce — wherever language intelligence matters.
