Catch the Reddit threads that matter.
Reply before they go cold.
A keyword alert tells you something matched. ThreadScope reads the whole thread, weighs it against what you care about, and gives you the context to reply well - all in one place.
Forty seconds, feed to reply.
Watch ThreadScope turn a noisy stream of subreddits into the two or three threads worth your time - then draft the reply for you. And when a post isn't your moment, it says so.

Built by a DevRel to scratch his own itch.
I'm Ben. Developer relations is my day job, and a lot of the best conversations happen on Reddit - where the good threads move fast and are easy to miss. I kept finding posts I could genuinely help with days after they'd gone quiet, and the usual ways to keep up either buried me in noise or nudged me toward the kind of drive-by self-promotion I'd never actually post.
So I built the tool I wanted for myself: a quiet radar that surfaces the handful of threads worth showing up for, and an assistant with enough judgement to tell me when to stay out of one. ThreadScope is a solo project - just me, using it every day and shipping it as I go.
