AI website monitoring that explains each change in one line
A raw diff tells you that 214 characters moved. A good summary tells you that a competitor raised its price. WebsiteChange adds an AI layer on top of change detection: for every real change, an AI model writes a short plain-language summary and scores how much it matters, so your team reads one line instead of a wall of red and green.
What a summary tells you
The summary describes the change in the words a colleague would use in a chat message. It names what changed, from what to what, and where on the page.
Each summary sits on top of the change record, above the text diff and the visual diff, and it travels with every alert and digest.
- "Pro plan price raised from 79 to 99 USD per month; annual discount removed."
- "New paragraph in section 4 allows the vendor to use customer content to train AI models."
- "Product status changed from In stock to Backordered."
- "Five new open roles in Sales, all based in Chicago."
- "Homepage headline now targets enterprise IT teams instead of small businesses."
Importance scored low, medium or high
Alongside the summary, each change gets an importance score.
- High means the change is likely to need action: a price, a plan, a contract clause, availability, a removed product or a legal notice.
- Medium means a meaningful edit worth reading: new positioning, a new feature listed, a changed FAQ answer.
- Low means a minor edit: a typo fix, a reworded sentence, a swapped image with no new meaning.
The score drives your alerts. Send only high to Slack, medium and high to the page owner, and everything into a weekly digest. Set this per channel on the website change alert settings. Narrowing a monitor to one element, such as the pricing table, keeps both the summary and the score focused on what you care about.
Summaries run only on real, filtered changes
The AI model never reads every check. First the website change detection engine compares the page with the last version and removes noise: dates, counters, rotating banners, cookie bars, tracking parameters and your ignore rules. Only when a real change is left does the model write a summary.
This keeps summaries focused and keeps your allowance for changes that matter. A page checked every 15 minutes that does not change for a month uses no summaries at all.
Monthly summary limits per plan
| Plan | AI summaries per month |
|---|---|
| Starter | 300 |
| Growth | 1,500 |
| Business | 6,000 |
| Enterprise | 25,000 |
Summaries are counted as usage in your billing period. Deleting a monitor does not return summaries it already used. If you reach your limit, checks, diffs, screenshots and alerts keep running as normal, and new changes arrive without a written summary until the next billing period or until you move to a larger plan. There is no unlimited AI on any plan, which keeps every plan predictable.
A summary helps you read, it does not replace reading
The summary is a fast first reading of a change. It is not legal advice, financial advice or a guarantee that nothing else changed. For a contract clause, a regulatory notice or anything you will act on, open the change and read the diff itself.
That is why the raw diff is always one click away. Every summary links to the full text diff with each added and removed word marked, and to the page change monitor view with the changed areas highlighted on the screenshot. The original versions stay in your website archive tools, so anyone can check the summary against the source.
How teams use summaries day to day
Product marketing reads the morning digest in two minutes and forwards only the high importance lines to sales.
Legal and procurement get a short line for each vendor terms change and open the diff only when the score is high.
Ecommerce teams see price and stock summaries in Slack and decide on a response before the next check.
Agencies paste summaries straight into client updates, with a link to the change for anyone who wants the details.
Leaders who never log in still understand what changed, because the alert says it in a sentence.
AI website monitoring questions
No. A summary runs only when a real change remains after noise filtering and your ignore rules. Quiet checks never use the AI.
Monitoring, diffs, screenshots and alerts keep running. New changes arrive without a written summary until the next billing period or a plan upgrade.
No. A summary is a help for reading, not legal advice. The raw text diff and screenshots are always one click away for a full review.
The AI model scores each change as low, medium or high based on what changed, such as a price, a clause or availability and where on the page it happened.
