There's certainly a lot of tools that focus on individual parts of the problem (e.g. the OCR layer, or workflows on top). But very few that solve the problem end-to-end with enough flexibility for AI teams that want a lot of control over the experience.

For example, we expose options for AI teams to control how chunking works, whether to enable a bounding box citation model, and whether a VLM should correct handwriting errors.

Most customers we speak with, the evaluation is actually between Extend or building it in-house (and we have a pretty good win rate here).
