How the AI works
How AI-Powered Event SMS Works
Not the internet. The assistant answers from the brief you wrote, cites where each answer came from, and hands anything it cannot source to a person. No invented parking lots, no confident wrong wave times.

One event brief answers on SMS, WhatsApp and webchat.
Four steps, no prompt engineering
From your brief to a live number.
- 01 2 min
Upload the brief
The athlete guide, the DPW notice, the parking map, last year's FAQ. PDF, Word or pasted text.
- 02 2 min
Import the roster
RunSignup, Race Roster, Eventbrite or a CSV. Phone numbers, distances and waves map on import.
- 03 30 sec
Pick a mode
Autonomous, Approval or Learning. Change it any time, including in the middle of race morning.
- 04 Instant
Publish the number
Print it on the bib, the banner and the parking sign. It answers from that second on.
Grounded answers
Every reply shows its source.
Answers come from your brief, your broadcasts and answers you have approved before. Open any thread in the dashboard and see the exact line the assistant used. If nothing in your material covers it, it says so and escalates instead of guessing.
- Your event brief
- PDFs and documents you upload. The primary source for anything factual.
- Your broadcasts
- A 6:31 AM reroute becomes the answer to course questions for the rest of the day.
- Approved answers
- Anything you answered by hand and approved, carried forward to future events.
- Nothing else
- No web search, no general knowledge about your venue, no filling in gaps from other events.
Thread detail · staff view
Sourced from
race-brief-2026.pdf, page 2: "Transition area closes 7:45 AM. Wave 3 (Olympic men 35-39) starts 8:20 AM."
No matching source means no answer. The assistant replies that it is checking with the team, and the question lands in your inbox marked held.
You choose how much rope it gets
Three modes, switchable mid-event.
-
Autonomous
Replies on its own in under 5 seconds. Anything outside your material is held for a person instead of guessed at.
Race morning, high volume
-
Approval
Drafts every reply and waits for your tap. Slower, but nothing reaches an athlete without a human reading it first.
First event, or a sensitive one
-
Emergency Brake
One tap stops the AI completely and sends only your alert, so nothing on the number can contradict you.
Weather hold, incident, evacuation
It gets better every event
Answer once, never again.
Learning Mode turns every escalation into knowledge. You answer a resident or an athlete once, approve it, and the assistant owns that question for every future event. Your second year is quieter than your first.
| Question the AI could not answer | Asked by | Status |
|---|---|---|
| Can I switch from Olympic to Sprint this late? | 7 people | Answer it |
| Is the finish line beer garden 21+? | 4 people | Answer it |
| Where do I return the timing chip? | 3 people | Answered |
| Can my kid ride the course with me? | 2 people | Answered |
| Do you have a lost and found? | 2 people | Answered |
Approve an answer and it applies to everyone who asks next, including in Spanish and Portuguese.
The honest limits
- Will it make things up?
- It answers only from your material and shows the source line. When nothing matches, it says it is checking with the team and escalates. You will see held questions in your inbox rather than discover a wrong answer later.
- Can it take a registration or a payment?
- No. It answers questions and sends broadcasts. Anything transactional, like a distance change or a refund, is routed to a person with the athlete's details attached.
- What if two documents disagree?
- It flags the conflict to you instead of picking one. Your most recent broadcast always wins over an older document, which is why a 6:31 AM reroute overrides the printed guide.
- Who sees the conversations?
- You and the staff you invite. Threads are visible in the dashboard with sources attached, exportable, and deleted on the retention schedule you set.
Ask it something hard.
Text the number and try to break it. That is the demo.
