The Problem

Getting fit is hard enough.
Your tools shouldn't make it harder.

Sound familiar? You're not alone. These are the reasons most fitness journeys fail before they begin.

💸
"A good trainer costs $100+ per session."

The average personal trainer charges $65–200 per session. At 3x/week, that's $1,000+ per month — before you've bought a single protein shake. Real coaching feels financially out of reach for most people.

📱
"I downloaded five fitness apps and use none of them."

The average person downloads 2–3 fitness apps per year and abandons them within 3 weeks. Static workout plans don't adapt to your life. Push notifications feel like guilt trips, not coaching. And there's always another app to try.

📋
"The plan doesn't know me. It's the same for everyone."

Pre-built programs don't know your bad knee, your midnight schedule, your home gym of two dumbbells and a mat. Generic plans produce generic results. You need coaching that adapts to your life — not the other way around.

🌊
"I always fall off. Nobody notices. Nobody cares."

Miss a week and your app doesn't even notice. A real trainer would ask where you've been. They'd adjust the plan. They'd keep you accountable. Without that, small setbacks become permanent stops. You need someone — or something — that's actually paying attention.

The Solution

Meet Chiron. Your AI trainer
who actually knows you.

Named for the mythological centaur who trained the greatest heroes of ancient Greece, Chiron brings that same dedication to every single conversation — adapting to your life, your body, and your goals.

Smart Gym Setup

Show Chiron your gym. It plans around it.

During setup, just take a photo of your workout space. Chiron identifies your equipment — barbells, cables, machines, resistance bands — and designs every future workout around exactly what you have available.

  • AI identifies equipment from a photo
  • Works for home gyms, commercial gyms, or just a mat
  • Update it anytime with new equipment
  • Combines with your goals for perfect programming

Simple by Design

Up and running in minutes

No gym consultation required. No paperwork. Just three steps.

1

Connect & Tell Chiron Who You Are

Tap your Telegram or iMessage link. Chiron will ask about your goals, current fitness level, available equipment, diet preferences, and schedule. It takes about 5 minutes — and that data shapes every future interaction.

2

Chat Every Day, Naturally

Ask for today's workout. Log your meals with a photo. Check in on your progress. Ask about an exercise you're not sure how to do. Chiron is available 24/7 — not just on gym days, not just when it's convenient. Always there, always adapting.

3

Watch the Progress Stack Up

Week by week, Chiron builds a picture of your body, your habits, and your progress. Weekly recaps show exactly what worked. The longer you train with Chiron, the smarter it gets about you — and the better your results become.

Platform Flexibility

Telegram or iMessage.
Same Chiron. Your choice.

Every feature Chiron offers on Telegram is available on iMessage too. Photo meal analysis, workout generation, progress tracking, personality modes — all of it, delivered to your Apple Messages inbox for just $2/month more.

The only minor difference: Telegram supports tap-to-select buttons for menus like personality switching. On iMessage, those same menus appear as numbered text options — you reply with a number. Same outcome, slightly different interface. Every other feature is identical.

FAQ

Common questions

No app download required — ever. Chiron works through Telegram (free, available on all platforms) or iMessage (built into every iPhone). If you already have either of those, you already have everything you need. Just click your activation link and you're in.
When you send a photo of your meal, Chiron uses AI vision to identify the foods on the plate, estimate portion sizes, and calculate macros (calories, protein, carbs, fat). It then adds those to your running daily total and compares against your personal nutrition targets. Results are estimates — they're more accurate for standard foods and meals where portions are visible, and less accurate for very mixed or obscured dishes.
Both. Chiron handles personalized workout programming (push/pull/legs, full body, HIIT, home workouts — whatever you need), nutrition guidance (macro targets, meal tracking, photo analysis, daily totals), and body composition tracking (weight, body fat %, measurements over time). It's the only AI coaching product that integrates all three in a single conversation.
Functionally identical. Both support photo messages, all commands, full AI conversation, and every Chiron feature. The only difference is the interface for menus: Telegram shows tap-to-select buttons (more polished), while iMessage shows numbered text options you reply to. The $2/month iMessage add-on covers the cost of the business messaging service (Sendblue) required to send and receive iMessages from a business account.
Chiron's motto is "Every Day is Day One." Missing a day doesn't break your plan — it just means today is your fresh start. Chiron will never shame you for missing workouts or "bad" eating days. It picks up where you left off, adjusts if needed, and focuses on what's in front of you. That's the whole philosophy.
