Collections, archives and heritage organisations often hold documents in multiple versions: scans, edits, transcripts, reports, inventories or publications that have changed over time. Manually comparing such files takes a great deal of time and makes it difficult to see exactly what has changed. With PDF comparison, we help make differences between documents visible automatically. This quickly shows which content has been added, removed or changed, and creates a better starting point for review, research and document management.

We help you compare PDF files for textual and structural differences. We make changes visible, such as added or deleted passages, revised wording and differences in structure or pagination. This is valuable for checking revisions, comparing transcripts with scans, tracking changes in documentation and managing multiple versions of the same file. It saves time, supports more consistent work and gives you more control over document flows and content changes.

Control and quality

AI does the preparatory work. Results remain reviewable and are configured around your sources, fields, terminology and quality criteria. Where relevant, the source or passage remains traceable. Your organisation decides what is adjusted, approved and ultimately used.

A concrete first step

We prefer to start with a clearly defined test set. Together we agree the required output, quality criteria and review flow. This shows what works before you scale up.
