About Tansa

Write to a higher standard Tansa is an advanced text proofing system that can check thousands of words per second. Not only will it correct nearly all spelling, style, punctuation and hyphenation errors, it also ensures that everyone in your organization follows the same set of rules. Headline optimization Tansa uses generative AI to analyze an article to produce compelling and SEO-friendly headlines. It identifies relevant keywords that boost SEO performance and uses natural language processing (NLP) to create engaging, relevant and accurate headlines. Summarization Tansa’s article summarizer can help organizations quickly and accurately create news briefs. By analyzing the content of an article, Tansa can extract the key points and generate a concise and comprehensive summary. Accuracy check Using advanced NLP algorithms, Tansa scans headlines and articles, analyzing the content, context and tone. By cross-referencing the headline against the article’s body, it detects discrepancies, inaccuracies or misleading statements. Keyword identification Identifying relevant keywords is essential for improving the visibility of news articles. Tansa’s AI tools employ sophisticated keyword analysis to identify the most appropriate and trending words for a given topic. This aids news creators in optimizing their articles for search engines and ensuring that their content aligns with current trends. Social media posts Crafting effective social media posts is crucial for promoting content. Tansa’s tools generate compelling and concise posts that are optimized for various platforms. They consider character limits, trending hashtags, and audience engagement strategies. Translation It’s a small world... and many publishers need to produce content in multiple languages. Tansa’s translation service can assist in this process by offering high-quality, automated translations that are accurate and coherent. Everywhere you need it Tansa is a flexible solution that works in the most popular text editing applications, web platforms and page layout software. Custom dictionaries Your dictionaries can be adapted to suit your organization perfectly. We can help customize your solution by analyzing a large volume of your company’s published text. Save time and money Our customers have documented dramatic increases in productivity, reducing copy editing time by as much as 40 percent and drastically reducing published errors. Improve readability Tansa can identify the number or length of characters, words, sentences and syllables to ensure Plain Language guidelines are achieved. Tansa’s readability score is based on several indexes, including Flesch-Kincaid, Dale-Chall and SMOG. Write with variety and precision Tansa will suggest synonyms where there is more than one option. Synonyms develop your writing by giving you a more varied and richer vocabulary. Make your own adjustments The Tansa Web Admin is designed to work as both an interactive tool to direct Tansa’s proofing engine and as a searchable style guide. The type of permissions given to users are based on the users’ roles. Administrators will be able to edit and manage entries, while the majority of users will only be given permission to view entries and make suggestions. A multi-lingual solution Our solutions are available in more than a dozen languages. Multiple languages can be supported in a single environment which makes it easier for our customers to distribute the solution to offices around the world. Integrated and customized for your tools Use Tansa’s APIs or drop our proofing client into almost any editorial system, proprietary or out of the box. This creates a centralized editing solution, whether your users are working in Microsoft Word, Adobe InDesign or your own custom-developed web CMS. Privacy is paramount Your text is protected while being analyzed, never stored and not used for training generative AI. We prioritize keeping your content secure and confidential. Customers worldwide uses Tansa More than 150k writers, editors and page designers around the world use Tansa on a daily basis to improve their editorial workflow.
