what changed on Stripe pricing?

Yes. Yesterday they raised the Pro tier by 20% from $25 to $30/month. This matters because the main self-serve offer is now positioned higher.

How it works

Add a URL, get notified

Add any page from the dashboard or bookmarklet. DidItChange checks it on a schedule, spots what changed, and sends you a summary by email or RSS. Optionally, connect your AI assistant via MCP to ask questions about changes directly.

1

Add the page

Paste a URL or use the bookmarklet when you are already on the page you want to track.

2

Detect the change

Keep history, compare versions, and classify important movement including pricing and high-signal changes.

3

Review or route it

Use the workspace, read the AI summary, or consume the feed through email, RSS, or MCP.

Optional AI connection

Add this MCP endpoint to ChatGPT, Claude, or any compatible client. Select OAuth for authentication.

Alternatives

Why teams move beyond manual monitoring

Method	The Problem
Browser extensions	Useful for capture, but not enough on their own. You still need history, diffs, summaries, and organization.
Email alerts	Inbox noise without enough context, grouping, or historical review.
RSS feeds	Most important pages no longer publish them, especially pricing and product pages.
Google Alerts	Only indexed content. No page-level diffs.
Ask AI directly	It can explain changes, but it cannot monitor a page over time without a product like this behind it.

DidItChange: Set up once, monitor continuously, and review the few changes that actually matter.
