PageDiff plain-language change log

Watch pricing and policy pages, get paragraph-level before/after, not screenshots

Problem

A poster complains that Visualping, Distill and Versionista act like a camera: they screenshot on visual change, so alerts are noisy and never answer what a page actually said before and after. Small businesses also report being overwhelmed by updates and having no one to diff terms and pricing by hand.

Solution

Capture target pages as paragraph- and structure-level text snapshots, notify only on substantive wording changes, and show a side-by-side diff plus a summary of impact. Change history is publicly shareable, ideal for policies, pricing pages and help centers.

Users

SaaS founders tracking competitor pricing and terms, compliance and support teams, procurement staff

MVP

User submits URLs and picks which blocks to watch; scheduled capture builds paragraph snapshots; email alerts on substantive change with side-by-side diff; public read-only change page

Revenue

Subscription by number of watched URLs, free for 3; team plan adds sharing and alert channels

Why now

Most competitors are still screenshot-based, and LLMs make semantic paragraph diffing cheap; a solo build needs no heavy operations
