Why Reflex

In a slump, everyone's got advice. It's easy to forget what actually worked.

Coaches, 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.

How it works

Thirty seconds after practice.

Your AI hitting journal, built by voice.

1

Talk it out.

Hit record and say what happened, like you'd text a friend after a session. No forms, no typing.

2

Rex writes it down.

He cleans it up and organizes it for you — what worked, what didn't, what to keep — and saves it for good.

3

He reminds you what worked.

Next time you're struggling at the plate, Rex brings back the exact fix that got you right before.

From the founder

"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."

Jacob Founder
"You'll forget what worked. I won't."

Questions

Straight answers.

What is Reflex?

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.

When does it launch?

Summer 2026. Anyone on this list gets the launch email the day the app drops — and the founding 500 lock the founding price right then.

Will Rex actually help, or is it AI hype?

Rex isn't ChatGPT with a baseball wrapper. He's been rewritten a dozen-plus times against real journals to stop generic coaching talk. No lectures — one specific observation per session, grounded in your own log.

How long does an entry take?

Thirty seconds. Talk it like you'd text a friend after practice. Rex cleans it into a structured log. Most hitters do it on the car ride home.

Is there a free trial?

Yes — 7 days free if you start on the annual plan. After the trial you're charged $69.99 (founding 500) or $99.99 (standard). Monthly is direct: $14.99/mo, no trial. Cancel anytime.

Is my data private?

Yes. Your entries, videos, and stats are yours — never sold, never shared with other users, and never used to train any AI model.

The point

Less guessing. Out of slumps faster. More confident at the plate.

Reflex is the AI baseball journal that keeps what works for you — so you stop forgetting your best swings, and start trusting them again.
