Custom models built for your needs We develop tailor-made AI models based on your data, region, and analytical goals. Below are real examples of custom solutions we've delivered for world-class organizations. We built a custom model for the World Bank and the International Organization for Migration (IOM) to estimate caste groupings from Indian names, enabling research on internal migration and social inequalities. We created a high-precision transliteration model for cross-border identity providers to convert Mandarin and Kanji names into Latin scripts, improving international interoperability. We developed a custom model for international risk analysts to support geopolitical analysis, compliance monitoring, and decision-making based on onomastic intelligence. Why Namsor : The most accurate name origin and classification technology Choosing the right solution for name-based analytics is critical when precision, scale, and trust matter. Unlike generic AI or basic indexation tools, Namsor delivers expert-level onomastic analysis — combining morphological understanding, linguistic context, and cultural nuances to reach unparalleled accuracy. Verified by science. Trusted by institutions. Namsor has contributed to over 600 scientific publications and collaborates with some of the world's most prestigious universities, international organizations, and global companies. Following numerous audits and benchmarks by scientific, academic, and independent bodies, Namsor's name verification technology has been rated as the most accurate in the world . These evaluations, performed on a wide range of Namsor functionalities, have demonstrated a significantly higher level of precision compared to other solutions: Rated most accurate by Science-Metrix for Elsevier and the European Commission, Namsor was selected for the EU's official SheFigures gender statistics. Harvard & University of Chicago Namsor was validated on 250,000 individuals from North Carolina's voter registry — showing high alignment between predicted and self-reported ethnicities. A comparative study on U.S. race/ethnicity inference tools concluded that Namsor outperformed all alternatives. Evaluated on 90,000 researchers names, Namsor demonstrated outstanding accuracy for origin and ethnicity prediction. An audit carried out by Research Done to validate the results obtained via Namsor. "It is actually fascinating to see how close the estimation were to the real data, especially with key parts of the analysis." Zack Kertcher, Research Done Namsor vs. other solutions: how we compare Below is a comparison between Namsor and other common approaches like LLMs , basic databases, and general onomastic APIs : Our technology : How we turn names into deep insight At Namsor, we've built a unique artificial intelligence dedicated to the morphological and cultural analysis of names . Unlike generic AI or simple databases, our models are rooted in over a decade of expertise in natural language processing (NLP) and onomastics — the scientific study of names. Our technology analyzes the structure, context, and cultural signals embedded in names to estimate their origin, ethnicity, gender, country of residence, or even sociocultural categories like caste, or to make transliteration. Our tools work not only with full names, but also with nicknames, brand names, or non-standard spellings — across thousands of naming conventions and 22 alphabets: Cyrillic, Georgian, Latin, Arabic, Devanagari, Bengali, Greek, Armenian, Thai, Hebrew, Kannada, Gujarati, Tamil, Hangul, Telugu, Gurmukhi, Oriya, Han (Chinese traditional and simplified characters, Kanji), Hiragana, Myanmar, Katakana and Malayalam . We also design custom AI models to meet the specific challenges of our clients. Whether it's for a particular geography, industry, or data environment, we build bespoke solutions that go beyond our standard APIs. What makes Namsor unique is not just its architecture, but the way it's continuously refined. Our AI evolves through active research partnerships and ongoing collaboration with top-tier institutions : Universities Harvard, Berkeley, Sciences Po, VNU, etc. Scientific groups Elsevier, Springer Nature, The Lancet, ASME, SSRN, etc. International institutions United Nations, European Commission, IOM, OECD, World bank, etc. Experts Historians, linguists, anthropologists from around the world. These collaborations help us integrate new knowledge, validate results, and maintain a high level of scientific rigor. From assembling our data sets to continuous learning, each step is designed to optimize our estimations. 1 Large-scale data collection After more than ten years of research, we've assembled a high-quality dataset made up of billions of names from diverse cultures, languages, and regions. 2 Onomastic model training We train our AI using onomastics and integrate insights from linguistics, morphology, and cultural analysis. 3 Model validation We evaluate multiple models in parallel using specialized metrics to identify edge cases, anomalies, and potential biases. 4 Continuous learning Our team continuously refines these models and retains only the best-performing versions to ensure maximum reliability and accuracy. Our commitments : Ethics & responsibility At Namsor, we believe that powerful technology must come with a deep sense of responsibility. Our solutions are designed to deliver precise name-based insights while strictly respecting individual privacy , ethical standards , and regulatory frameworks such as the GDPR . We give every user full control over how their data is used. By default, submitted contributes to improving our models. You can easily disable this by turning off the “learnable” option via the API or dashboard. You can also activate the “anonymised” mode , which uses SHA encryption to fully anonymize the data — ensuring privacy while still allowing fast, consistent processing. This level of transparency and flexibility is rare among AI providers, and a key reason why organizations choose Namsor for responsible data analysis. Ethical design and GDPR compliance Namsor only collects the minimum data required for model training and predictions. All data is handled legally and ethically , with a focus on data minimization, transparency, and proportionality. We strictly comply with GDPR and other international data protection laws. To ensure full explainability , the Namsor API offers a special option: a detailed explanation of the AI reasoning behind each prediction.
