Where is the demand coming from?
Mixed
Some genuine outside demand, some founder reach. This is the read that decides whether the traction would transfer to you.
Roughly what does it earn?
Not disclosedNo basis to estimateWe do not publish a figure until we have something to base it on. When we do, the method that produced it is shown alongside the range.
Could you build it?
Yes, in about 2 weeks
Nothing patented, no network effect, and no proprietary data set standing in the way.
What it is
Attn is a keyboard-first, offline-capable desktop Gmail client for macOS and Windows built to replicate Superhuman's speed without subscription costs. The founder published source code on GitHub after a single reddit post in r/SideProject, positioning it as a local-first alternative that syncs when reconnected.
The one thing to knowZero revenue signals, no distribution amplification, and early-stage GitHub-only presence suggest this is a personal tool shared early rather than a commercial product yet, limiting immediate traction risk but also undermining wedge urgency.
