Two versions of a report, a policy, a proposal, or a contract: Quietra shows every added, removed, and changed word, grouped by section, with a short note on what each change does. The comparison runs on the phone; neither file is uploaded.
Quietra's Compare is a deterministic word-level comparison, the method used by professional redline tools, so it never misses or invents a change. Results are grouped by section and graded: normal edits, heavy revisions, or too different to compare meaningfully.
Scanned PDFs are supported: pages that are images are read with on-device text recognition first.
Checking a final PDF against the draft you approved.
Reviewing a counterparty's revised agreement before signing.
