RespondAI – monitors HN mentions and drafts your reply in 30 seconds

Hey ,

I built RespondAI after realizing how fast HN threads move.

A negative post can hit 200 upvotes in 30 minutes. Most founders

find out way too late — when someone DMs them "did you see this?"

So I built a tool that:

- Scans HN every 5 minutes for your brand/competitor keywords

- Scores each mention: Risk (1-10) and Viral potential (1-10)

- Sends a Slack alert with a founder-style reply draft ready to paste

The goal is to respond in under 30 seconds, not 30 minutes.

What it doesn't do yet (honest list):

- Reddit / Twitter monitoring (coming soon)

- Dashboard to manage keywords

- Anything fancy

It's free to start — just enter your keywords and Slack webhook.

Would love brutal feedback, especially:

1. Is the reply draft actually useful or just noise?

2. What would make you pay for this?
