Diffee VS Auto Refresh Extension

Auto Refresh Extension's answer:

It started with a simple extension: auto refresh any tab on a timer. People used it for restocks, appointment pages and ticket drops, but refreshing a page still means sitting there watching it.

So I added the part that does the watching. Our AI looks at the page the way you do and alerts you when what you care about changes, even with your browser closed. I'm a solo developer who has shipped Chrome extensions before, and I kept the free refresh timer free so the tool stays useful on its own, with paid monitors for people who want to stop checking altogether.

Auto Refresh Extension's answer:

It combines a free auto refresh timer and an AI page monitor in one extension.

• Describe, don't configure. Tell the AI what you're waiting for in plain language ("alert me when this drops below $150"). No CSS selectors, no code.
• It sees the page like you do. The AI looks at the rendered page, so it handles prices, buttons, badges and text that simple text-diff trackers miss, and it isn't thrown off by small layout changes.
• Runs without your browser. Monitors check from our servers, so they keep working when your laptop is closed.
• Pay per monitor, not per month. Each monitor shows its exact price before it starts (about $1.26 for 30-minute checks over a week with email alerts). No subscription.
• Free auto refresh, forever. Timer from a few seconds to a few hours, hard refresh, and auto-start. No account needed.

Auto Refresh Extension's answer:

• Easier setup: you chat with the AI instead of picking page elements or writing rules.
• Fairer pricing: you pay only for the monitors you run, and you see the price up front. There is no monthly plan to keep paying for a watch that ended.
• Smarter checks: AI vision reads the page like a person, so conditions like "size 10 is back in stock" or "a new appointment slot opened" work where plain change detection just says "something changed".
• Two tools in one: a free refresh timer for quick jobs, and a server-side monitor when you don't want to babysit a tab.
• Alerts where you are: email, WhatsApp and Telegram.

Worth knowing: pages that need a login can't be monitored, and some sites block automated visits.

Auto Refresh Extension's answer:

People who are waiting for something to change on a public web page and are tired of checking it by hand:

• Shoppers tracking price drops, restocks and limited releases
• People hunting appointment slots (visa, passport, clinic, booking pages)
• Buyers watching ticket sales and event registrations
• Job seekers watching job boards and listings
• Anyone who needs a dashboard, live score or results page to stay fresh

Most are non-technical, which is why setup is a chat rather than a settings page. Users are spread across the US, Europe, India and Japan.
