ChatGPT + DidItChange

track stripe.com/pricing

Done! I'll watch stripe.com/pricing and remember every change.

3 days later...

anything new on Stripe?

Yes! Yesterday they raised the Pro tier by 20% from $25 to $30/month. The Enterprise tier now includes priority support.

Quick start: Add this MCP endpoint with OAuth https://diditchange.app/mcp

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.

Use cases

What will you track?

Competitors Developers Professional Personal

Competitor Intelligence

• Pricing pages - Know when competitors adjust pricing or add tiers
• Feature pages - Never miss a competitor's product launch
• Changelogs - Track what competitors are shipping week over week
• Job postings - See where they're investing (hiring for AI = AI product coming)

"We caught our competitor's price drop within hours. Adjusted our positioning before losing a single deal."

Developer Workflows

• API documentation - Know when breaking changes are coming
• Dependency changelogs - Track releases of libraries you depend on
• Status pages - Monitor third-party service reliability
• Platform announcements - AWS, GCP, Vercel policy and feature updates

"Stripe deprecated an endpoint. We knew before our code broke in production."

Professional Monitoring

• Compliance pages - Track terms of service and policy changes
• Regulatory updates - Government and industry regulation changes
• Industry news - Track news sections on key industry sites
• Grant announcements - New funding opportunities the moment they're posted

"We track FDA guidance pages. First to know about regulatory changes affecting our clients."

Personal Tracking

• Job postings - Be first to apply when your dream company posts a role
• Product availability - Limited drops, back-in-stock alerts
• Event tickets - Concert and show ticket releases
• Price monitoring - Track items waiting for a price drop

"Tracked the careers page at my dream company. Applied within an hour of the posting."

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.
