What Fonto Editor is

Fonto Editor is an online XML editor for teams that need to create or revise structured content without requiring authors to have XML experience. It validates edits in real time against the schema in use, including DITA, JATS, S1000D, and custom schemas. Editing tools include comments, metadata changes, drag-and-drop restructuring, copy and paste, and track changes. The editor also supports version control, translation, review workflows, and previews for outputs such as HTML, PDF, e-books, learning platforms, magazines, and manuals. Fonto says it supports any XML schema and can integrate with content management systems, digital asset management systems, and repositories; named integrations include SharePoint, Google Drive, OpenText, and MarkLogic. It is offered through web, API, and self-hosted platforms, and its architecture can accommodate MathType for formulas. Fonto says the product has handled large publications, but it does not store content or provide workflow itself, so it needs a CMS, workflow system, or repository. Pricing is on request, and a free trial is available.
