Webpage monitoring with versions, diffs, and review built in
Add the URLs that matter to your team. Compare Versions saves snapshots on a schedule, flags when content changes, and gives you highlighted diffs, a Main view inbox, and email alerts — for webpages and PDFs, with folders for categorization and optional email digests.
10 URLs · 30 days free · Daily checks included
More than an alert — a full review workflow
Review your way
Side-by-side, single page, text-only, text-in-context, and image diff when enabled.
Pay per page
One domain with many URLs counts as many URLs — scale your list honestly.
How it works
Add your URLs
Paste pages you are authorized to monitor — product sites, docs, news, rate pages, PDFs, and more. Organize with folders.
We check on a schedule
Each run fetches the live page and compares it to the last snapshot. No change → no noise.
Review what changed
Open highlighted diffs, triage Main view, or read the email digest — then mark reviewed.
Review changes the way you work
Side-by-side when you want two panes; single-page merge when layout shifted; text-only and text-in-context for fast skim. Orange and cyan highlights show what moved — with size and word-count insights (S/M/L, TWC, DWC).
- Side-by-side or single-page layout
- Text and table changes, not screenshot-only noise
- Mark reviewed when done
One inbox for every change
After each monitoring run, changed pages appear in Main view. Filter by folder, site, or unreviewed only — then open the diff in one click.
- Group by site or date
- Folder chips for departments or topics
- Unreviewed filter for daily triage
Morning email when pages change
Get a digest after each run: which URLs changed, insight summary, and links to open each diff. Turn alerts off or set a minimum DWC threshold in Settings.
- Summary table + link to each diff
- Manage alerts in account settings
- Same insight labels as the app (S/M/L, TWC, DWC)
