For coaches comparing platforms
The CoachRx alternative that puts your program design to work 24/7.
CoachRx is a serious tool for coaches who individually design every program. Agents4 respects that craft — and multiplies it: an agent that learns your design logic, coaches with it around the clock, and leaves you the judgment calls.
What CoachRx does well
Built by OPEX, CoachRx is genuinely good professional program-design software — a strong design workflow, exercise library, and a coach-education ecosystem around it. For coaches whose craft is individual design, it's a credible daily driver.
The difference in one look
CoachRx: A design workbench
CoachRx makes you faster at writing individualized programs. But the writing, the answering, and the adjusting still consume your hours — the tool sharpens your workflow, it doesn't work your roster.
Agents4: A coaching agent
Agents4 learns the design logic behind your programs — progressions, substitutions, thresholds — then applies it: drafting plans you approve, answering clients in your voice, and adjusting to check-ins and wearables while you sleep.
Job by job, side by side

Common questions
Is Agents4 a CoachRx alternative?
It serves the same coach — one with a real methodology — but differently: instead of a faster workbench for writing programs yourself, it's an AI agent that learns your design logic and coaches with it between sessions, with your approval on what ships.
I individually design everything. Won't an agent flatten that?
The agent is built from your design logic — your progressions, substitution rules, and thresholds — and drafts individually for each client's history, equipment, and constraints. You review and edit anything before it reaches a client, so the individualization stays yours.
How does it learn my programming principles?
You upload real programs, templates, videos, and notes. It learns the patterns behind your decisions — expect a faithful agent within 2–4 weeks depending on how much you share.
What happens to my methodology?
It stays private in your workspace and is never downloadable. Marketplace subscribers get your agent's coaching — never your underlying files.
What does it cost?
Founding coaches pilot with up to 5 clients free, then keep early-adopter pricing, and earn 80% of every marketplace subscription to their agent.
