3di Information Solutions is a UK-based technical writing, translation and localization, and content operations service provider founded in 2002. It primarily serves companies that manufacture complex products or software. Rather than a typical subscription-based SaaS platform, it focuses on project delivery, outsourced teams, and consulting implementation, helping clients produce clear, reliable technical documentation that is ready for AI-driven use cases.
Its services cover technical manuals, product user guides, software user help, API and developer documentation, information portal development and hosting, translation and localization, content operations system development, and legacy documentation migration. 3di emphasizes tool neutrality and can deliver projects using tools such as Markdown, DITA CCMS, MadCap Flare, Git, Jira, Confluence, XTM Cloud, SharePoint, and WordPress. Its team includes technical authors, localization engineers, content tool developers, service managers, and a network of freelance specialists. It can act as an extension of an in-house documentation team or take on full outsourcing.
The website does not publish standard packages or self-service purchase pricing. Its process typically starts with understanding requirements, followed by scope definition, planning, and a detailed budget. The site states that its technical writing services are on average around 20% cheaper than hiring an in-house technical writer, and that product user documentation costs can be reduced by up to 30%. However, actual costs still depend on project scope, tools, and writing time.
Its strengths include more than 20 years of experience, over 300 clients, a client retention rate above 90%, and certifications such as ISO 9001:2015 and Cyber Essentials Plus. It serves industries including software, high-tech equipment, medical devices, telecoms, fintech, robotics, and industrial machinery, making it well suited to complex documentation scenarios with high compliance requirements. Its limitations are the lack of SaaS-style product features, permission systems, standard APIs, clearly defined packages, and online trials. Third-party integrations are more about delivery tool capabilities than a platform ecosystem.
It is suitable for European and North American companies that need outsourced technical writing, multilingual product documentation, content operations process restructuring, API documentation development, or legacy documentation migration. It is especially well suited to complex hardware, medical, software, and automation industries.
