I’ve been craving 鼎泰豐 Din Tai Fung’s chocolate xiao long bao for weeks now.
Every time I checked, I just could not find an evening slot 🫠
So the tired me, handed this task to Wajo AI’s Fo over iMessage, and I am impressed!
A handful of reasons …
→ Persistent, not one-shot. It didn’t just search once and give up, it polled availability at regular intervals, holding state across a task that spanned days, not a single session.
→ Guardrails instead of a leash. I gave it a payment method (a Visa debit gift card), so there was a hard ceiling on exposure, plus also configured hard spend limits. It gave me assurance to let it act autonomously instead of pinging me for a green light every step.
→ Recovered from failure instead of surfacing it as an error. The final confirmation hit a bot-check wall and got rejected. Most agents would’ve stopped and reported “failed.” This one retried through an alternate path in the background and kept me posted, without needing me to re-prompt it.
→ Kept optimizing after “done.” Reservation locked, and it’s still watching for a better (weekend) slot to swap me into - no fee, no extra ask, just continuing the objective. Big fan.
Isn’t this the real edge an agent has over a chatbot with tools? Holding a goal over time, recovering from failure, and knowing when to ask vs. just act.
I LOVE how Fo is acting like my digital EA.
It knows the objective and the boundaries, and figures out the rest across channels, over time, without needing me to babysit every step.
Well, who’s joining me for Din Tai Fung dinner? 🥟
