Talk about your session out loud. Reflex — your AI hitting journal — writes it down, keeps what worked, and reminds you the next time your swing feels off.
Download ReflexCoaches, teammates, your group chat, your own head — so many swing thoughts that you lose track of the one that got you right last time. Reflex keeps track of what works for you, and reminds you exactly what fixed it before. It's your AI hitting journal — and it remembers for you.
Your AI hitting journal, built by voice.
Hit record and say what happened, like you'd text a friend after a session. No forms, no typing.
He cleans it up and organizes it for you — what worked, what didn't, what to keep — and saves it for good.
Next time you're struggling at the plate, Rex brings back the exact fix that got you right before.
"I'm a hitter. I tried all of it — video analyzers, paper journals, albums in my camera roll. When the slump hit, I knew the fix was somewhere. I just couldn't find it.
Reflex is what I built so I wouldn't lose it again. It's not another opinion to weigh — it's a memory of what works for me. Through the highs, it keeps me there. Through the lows, it gets me out."
"You'll forget what worked. I won't."
Reflex is a digital baseball journal with an AI coach. Instead of typing, you talk through your session out loud — and Rex, your AI hitting coach, writes it into a clean log, remembers what works for your swing, and reminds you when you're struggling at the plate.
