A PDF engine built for the case file
A general-purpose PDF library does a little of everything a PDF allows — view, edit, fill, sign, script, save. Legal review needs just one of them — viewing — done exceptionally well: read the filed document faithfully, even when the file would defeat an ordinary viewer. Over five years we refactored an open-source engine into a read-only engine for legal review and tuned it for the work — recovering damaged files, holding memory flat all day, and finding the answers buried in form fields.
