AI-Powered Change Intelligence

Our AI doesn't just detect that a page changed; it reads and understands the content to determine relevance. It filters out noise and false positives, delivering concise summaries that explain what changed and why it matters to your specific monitoring goals, saving you from manually deciphering screenshots.

Natural Language Setup & Smart Link Following

How does Changeflow handle websites that require a login?

Changeflow employs advanced anti-blocking technology designed to navigate login walls and complex JavaScript. You can provide credentials securely, and our system will automate access with a 99.9% success rate, reliably monitoring pages that are typically inaccessible to other web scraping or monitoring tools.

What's the difference between Changeflow and traditional website monitoring tools?

Traditional tools often just alert you that "something changed" or provide side-by-side screenshots, forcing you to manually find the difference. Changeflow uses AI to read the page, understand context, filter out irrelevant changes, and deliver a plain-English summary of what actually changed and why it matters.

Can I monitor a large number of pages or an entire website?

Yes. Changeflow is built for scale, allowing you to organize thousands of web sources. For bulk imports, you can provide a list via CSV or Excel, or we can perform a site crawl. The platform then creates a unified, noise-free feed of key updates from all your monitored pages.

How are notifications delivered?

You receive concise, AI-generated notifications directly in your Changeflow dashboard and via email to specified addresses. For integration into other workflows, you can use the provided API or connect to thousands of other apps (like Slack or Teams) using Zapier for custom alerting.

How does the pay-as-you-go pricing work?

You purchase credits, which are only used when you send an invoice or quote. Each sent document costs €0.65. Your monthly spending is capped at €16.25, which covers approximately 25 documents. Any invoices sent beyond that in the same month are free. There is no monthly subscription fee.

Do my credits expire?

No, your purchased credits never expire. You only use them when you send an invoice or quote, and they remain in your account until used. This provides complete flexibility without pressure to use the service within a specific timeframe.

What payment methods can my clients use?

Your clients can pay your invoices online directly through integrated payment links. Supported methods include iDEAL, credit card, and Bancontact. This facilitates faster payments and reduces the need for manual bank transfer follow-ups.

Can I manage multiple businesses or client administrations?

Yes. TRONVoice is built to handle multiple administrations seamlessly. You get two administrative profiles for free, which is ideal for managing your own company and a side project. Accountants can add more client administrations for a fixed monthly fee per additional profile.
