Your AI finally remembers what changed
AI assistants forget between sessions. DidItChange watches websites 24/7 and tells your AI exactly what's new.

The problem
AI has amnesia
Did the pricing page update?
AI: "I can check the current page, but I don't know what it looked like before..."
What's new in the API docs?
AI: "I'd need to look at it now. I have no memory of previous versions."
Did that competitor ship yet?
AI: "I don't have access to track websites over time..."
Every conversation starts fresh. No history. No context. Your AI is clueless about what changed yesterday.
The solution
Now your AI has memory
Continuous watching
Monitors URLs in the background, even when you're not chatting.
Smart detection
Ignores ads, timestamps, and noise. Only meaningful changes.
Instant recall
Ask your AI naturally and get real answers about what changed.

Alternatives
Why not just use...?
| Method | The Problem |
|---|---|
| Browser extensions | Manual checking required. Changes don't flow to your AI. |
| Email alerts | Inbox noise. Still have to explain context to AI. |
| RSS feeds | Most websites don't have them anymore. |
| Google Alerts | Only indexed content. No page-level diffs. |
| Ask AI directly | It literally cannot remember what pages looked like before. |
