Building SignalAI — an AI that texts you when your inbox actually needs you
Working on something I've wanted for a while: an inbox that tells me what actually matters instead of me digging for it.
The problem, for me specifically: important stuff wasn't getting lost because I forgot about it. It was getting buried under fifty things that didn't matter, and by the time I found it again, it usually needed a reply I didn't have the energy for in that moment.
So SignalAI reads incoming email with AI, sorts what's genuinely urgent from everything else, and texts me directly when something needs a real response. Not a notification inside another app — an actual text.
Where things stand: it's live, I have a small number of real users, and I'm heading toward a proper launch in a few weeks. Still actively finding the rough edges.
Genuinely curious from this crowd specifically:
→ Has anyone else tried solving "email triage" before? What actually worked, or didn't?
→ For something charging $14-18/month, what would you actually want to see before trying it?
Happy to answer anything about the stack, the AI classification approach, or how the SMS piece works under the hood.
The strongest part is that SignalAI is solving triage by changing the delivery mechanism, not just adding another inbox view. The real-time SMS escalation makes the product meaningfully different from another AI email summarizer.
Thanks so much for your assessment.
Curious — what have you learned so far about when people actually want the SMS escalation rather than just a summarized inbox?
Good question. It is too early to tell. As it is designed now, messages marked as urgent or messages the user specifies (subject or sender) are SMS escalated. I may need to add more options as I get user feedback. I thought your original comment was very positive and succinct. Would you mind if I include it as an anonymous testimonial on my site? Thanks!
Absolutely, feel free to use it anonymously. And that makes sense — I’d be curious to see whether users end up wanting more control over what gets escalated once you have enough usage data.
