Try the Coach free — no signup required
Every visitor gets 100 free Coach tokens in their browser to try the OSB Coach on this Arc. That covers roughly 20 Coach interactions on the Fast tier — plenty to get a real feel for how the Coach guides you, captures your commitments, and follows up.
- Fast tier (free, default) — 5 tokens per signal. ~20 interactions on the starter allowance.
- Balanced tier — 4× cost, deeper context. Best when you're working through tough moments.
- Deep tier — 8× cost, fullest reasoning. Reserved for genuinely hard calls.
What you get when you buy
Includes 1000 OSB Coach tokens credited to your account on purchase. Tokens never expire and roll over across Arcs — they're a wallet, not a subscription. Coach memory, commitments, and check-ins all flow on top.
The Coach is delivered by OSB Coach, our digitally-created coaching system. AI is the engine; the Coach is the product.
Take the Coach anywhere — free browser extension (beta)
The DigitalExpo Coach is a browser side-panel that rides any tab. It watches what you're working on, coaches you through it one step at a time, writes the exact command into your DigiPad, and checks your result — the same Coach from your Arc, now beside you on the real web.
- Works on Chrome & Edge — 2-minute install, no store needed
- Voice or text — hands-free, and you can talk over it to interrupt
- Sign in to teach straight from the books you own
- Free while in beta.
