TECHNICAL PRO · $9.99 PER MONTH
Share technical files and review their open activity.
Create a share link for a JPG or PNG image, supported notebook, mailbox file, academic source, financial filing, CAD drawing or IFC model. Review when its link opens and use the available preview or download for that format.

What the current previews do
Opened.page uses deterministic file handling in the browser for its available previews. It does not execute notebook code or claim to be a full email eDiscovery, financial validation, CAD authoring, or BIM analysis suite. Some binary formats are provided as downloads for compatible desktop software. Large-format blueprint and multi-page archival TIFF processing are not included in Technical Pro.
