Common questions

Will Thread Detect post or write replies for me?

No. Thread Detect only finds relevant threads. You decide whether to join and write every reply yourself.

How many alerts will I get?

You may get up to three alerts a day. Some days you may not get any. We only send an alert when we find a relevant thread that is gaining momentum.

Will this work for products other than developer tools?

Yes, if the people you want to reach use Hacker News. Thread Detect works best for technical B2B products, including developer tools, infrastructure, AI, open source, and technical SaaS.

What happens after I enter my product URL?

We read your homepage and create a short product summary. You can review and edit it before creating an account. Then you add a payment method and start receiving alerts.

Can I cancel at any time?

Yes. You can cancel from your settings at any time. You can also get a full refund within 7 days of your first payment, no questions asked.

Spend less time checking Hacker News.

You do not need another dashboard to check or 50 alerts to sort through. We email you a few relevant discussions that are worth your time. Paste your homepage URL to get started.
