They refresh. They scroll. They scan for what changed. It takes twenty minutes and most days, nothing is different. the premise What if you had an employee whose only job was to watch those five sites and tell you only when something actually happened? what we built Diffwatch is that employee. An AI agent that never sleeps, never gets bored, and never sends you a "something changed" alert without an explanation. Stop watching. Start knowing. Diffwatch runs as an autonomous AI employee — watching your sources, filtering the noise, and telling you what matters.
