It started with one loud mind. It was never just about one.
Ersa exists because the tools for brains like ours just didn't exist. If your attention works like this too, she's for you.

I'm Georgie. I have ADHD, and not the quiet, distracted kind you see in stock photos. I mean the kind where boredom is physically uncomfortable, where one tab eats your whole afternoon, where you rewrite an email for twenty minutes that felt like five, where the thought that mattered most is somehow always the first one to vanish.
I tried the apps. All of them, blockers, timers, streaks, planners. And every single one asked me to already be the person I'd be if I didn't need them in the first place: organized enough to keep the system running, consistent enough to keep the chain alive. And every one of them found a way to make a bad day feel like a bad report card.
What I actually wanted just didn't exist: something that would notice. Notice the scatter before I even did. Notice the loop I was in. Hold the thought so my head didn't have to. Say one small, true thing, then leave the choice with me, because I'm not a problem that needs managing.
So I built her myself. I'm not a programmer, I built Ersa in partnership with AI, one decision at a time, testing everything against the only thing that actually matters: does this feel like being accompanied, or does it feel like being watched? Anything that smelled like surveillance, gamification, or guilt got cut. Didn't matter how "engaging" it was supposed to be.
That's also why Ersa's a she, and why she has an actual voice instead of a notification sound. A tool just does something. A companion is on your side.
Where this is going
Ersa starts on the Mac because that's where you can actually see the rhythm of attention. An iPhone version comes once beta testers start asking for it, an Apple Watch after that: catch a thought in two seconds from your wrist, get a held thought back as the gentlest little tap. Same brain everywhere, just different senses depending on the device.
Honestly, the goal was never really "an app." It's that someone with a loud mind opens their Mac one day and feels, maybe for the first time in a long time, accompanied instead of managed. Even if that's just one person, Ersa was worth building.
