How is this different from a page-change alert tool?

A page-change alert tells you that something on a page changed. SpyGlow shows you the exact text that changed, scores how much it matters to your business, and suggests what to do about it.

What about small edits like a timestamp or a cookie banner?

Page noise like pop-ups and timestamps never counts as a change, and each change is scored. Alerts go out only for changes at or above your importance threshold.

What if a page loads badly or shows an error?

SpyGlow checks it again instead of reporting a change, and you keep the last good version of the page.

What do I do with an important change?

Read the suggested response, then turn it into a tracked action, ask AskGlow about it or refresh the battle card for that competitor.

Changes

The intelligence layer

Change detection tells you that a page changed. SpyGlow gives you the exact words that changed, why the change matters to you, and an importance score that keeps small edits out of your way.

What you get

Everything packed into one workspace.

Old and new, line by line

Removed text struck through in red, added text in green, side by side when you want it. Works on any page you monitor.

Importance score

Every change is scored from 1 to 10 with a plain-English note on why it matters for your roadmap or your deals, and how confident the read is.

Price changes called out

On pricing pages, SpyGlow shows each price before and after with the percentage change, plus discounts, currency changes and plans added or removed.

Sorted by type

Pricing, product, content, design, hiring, integrations, press, legal and more. Filter by category, importance or competitor.

Clear the feed quickly

Mark read, dismiss, delete, export to CSV or turn several changes into tracked actions at once.

A suggested response

Each important change comes with what you could do about it, which you can turn into a task or a battle card.

In the details

The small things that save you time.

Needs attention first: The feed opens on critical and high-importance changes, with tabs for everything else.
Screenshot slider: Drag a slider between the before and after screenshots of a page, or open either one full screen.
Blocked pages ignored: A page that shows a check or an error instead of the competitor's content is never reported as a change.
Bad loads checked again: If a page loads badly, SpyGlow checks it again before telling you anything changed, so a slow load is never reported as "they removed half their page".
Site-wide edits shown once: A site-wide edit, such as a new footer link, shows up once instead of once for every page.
One report per check: Each check produces a report for the competitor: the main takeaway, why it matters, what changed on each page and what to do.
Evidence for every page: Open any page in the report to see its summary, text diff and screenshots side by side.
Copy what you need: Copy a report with only the sections you choose, ready to paste into Slack, a doc or an email.
Share without an account: Send a read-only link that expires in 7, 30 or 90 days. See how often it was opened and revoke it any time.
PDF and email: Download a report as a PDF, or send it to your inbox or, on paid plans, to your Slack channel.
Ask about any change: One click sends a change to AskGlow with the question already written.
Updates without refreshing: New reports appear on your dashboard and feed as soon as a check finishes.
