Tell TrailBrief your trip — hunting five days in Montana, a weekend loop above treeline — and it prepares expert-vetted guidance for the scenarios that matter on that trip. In the field, it answers you from your phone alone: zero bars, low battery, no problem.
A short questionnaire before you leave — activity, season, terrain, party — becomes a focused pack of guidance for your realistic risks. Not a 400-page manual.
Everything runs on your phone — understanding your question and finding the answer. No signal needed, designed to sip battery when you have 8% left.
Guidance comes from playbooks written and signed by wilderness-medicine professionals — surfaced exactly as reviewed, never improvised by AI.
Brief it before you go. On wifi, answer a few questions about the trip. TrailBrief assembles your pack — the scenarios that actually apply.
Ask it in the field. "I think my leg is broken and I'm alone." It understands the situation and opens the right playbook — offline, in seconds.
Follow vetted steps. Clear, calm, numbered guidance exactly as the reviewing clinician signed it — with when-to-evacuate always explicit.
The check-in switch. Add people to your brief — if you're not back by your check-in time, TrailBrief automatically sends them your trip plan and exactly what to do next, in order. It nags you first, so a dead phone doesn't panic your family. The one safety net that works because you have no signal.
