What Tansa Systems does

Tansa Systems is a Norwegian language-technology company founded in 1995 and headquartered in Oslo, with a North American subsidiary (Tansa Systems LLC, Lakewood Ranch, FL, established 2004). It develops, markets, and sells enterprise text-proofing software that performs contextual analysis of spelling, usage, style, punctuation, grammar, and hyphenation across 23+ languages. The core Tansa Text Proofing System is available as on-premise software or as a cloud-based SaaS solution, integrates with 120+ plug-ins across Microsoft Office, Adobe Creative Cloud, the major web browsers, and a broad set of newsroom editorial systems (AP ENPS, Arc Publishing, Woodwing, Vjoon, Atex/Polopoly, Naviga, Newscycle, WordPress, Ibexa, Sourcefabric, and many others), and exposes a JavaScript/REST/GET-POST API for proprietary integration.

The company monetizes through named-user enterprise software licences on multi-year contracts, SaaS subscriptions, ongoing dictionary-update subscriptions (with higher-frequency weekly/monthly tiers for press bureaus), and professional services including custom dictionary compilation, API development support, training, and installation. Its customer base spans three primary verticals: media and publishing (Financial Times, The Economist, Newsday, Toronto Star, The Seattle Times, Philadelphia Inquirer, Amedia, Schibsted, NRK, TV2, Berlingske Media, Irish Times), corporations (via Microsoft Dynamics and Office integrations), and government/public sector, where Norwegian municipalities and agencies use Tansa's Bokmål-Nynorsk translator to meet statutory 25% Nynorsk content requirements on public websites.

Between 2021 and 2025 Tansa has expanded the platform with a SaaS cloud deployment (2021), a Bokmål-Nynorsk automatic translator (2021), a Norwegian/Danish grammar-checking module (2022), and an offline Local SaaS variant for security-sensitive government and enterprise buyers (2025). In 2025 it added Tansa Create, a generative-AI suite for SEO headline generation, article summarization, keyword identification, multilingual translation, headline-content consistency checks, and a personal writing assistant—underpinned by an enterprise privacy partnership with OpenAI and selection into the FT Strategies / Google News Initiative AI Launchpad program. Distribution combines direct enterprise sales ([email protected]) with a network of 20+ software, language, and technology partners including Microsoft, Apple, Adobe, the Associated Press, the Canadian Press, and the Financial Times.
