How do I set up a page to monitor with Changeflow?
Setup is designed to be simple and iterative. You provide the starting URL and a brief, plain-English description of what kind of changes you want to be alerted about (e.g., "track price changes for the product listing" or "notify me of new press releases"). Our AI agent interprets your request, begins monitoring, and continuously refines its understanding to improve the relevance of alerts over time. No technical skills are required.
Can my team collaborate and share monitored feeds?
Absolutely. Changeflow is built for business collaboration. You can create shared workspaces where team members can view, discuss, and manage monitored sources together.
