Trip planner for backpacking crews

Plan like one crew,
not six group chats.

One route, one roster, one shared plan — sent as a single link. Dates, rides, permits, gear, food, and the weather where you'll actually be, planned together instead of across forty threads.

The idea

Three steps from group chat to trailhead

1
Draw the route

Search a trail, snap paths together at real junctions, or upload a .gpx — Trailmix places camps at actual campsites and sizes the days, water, and food to the miles.

2
Text one link

The crew joins from any browser — a name, a tent-mate, a couple of stats. That's the whole onboarding.

3
Plan it together

Rides, gear, and food fill in as the crew joins — the shared load settles fairly on its own, and an AI trail buddy in the chat fields the "wait, what about…"s.

What it takes off your plate

the plan
The whole trip on one page

Dates, trailhead, drive plan, permits, the weather where you'll actually be — one page the whole crew can see, not a pinned message nobody reads.

the crew
Friends join from a text

No accounts, no downloads, no "what's the password". One link puts the whole roster — and their gear — on the same page.

the buddy
An AI that's read the plan

Ask the crew chat anything — "how cold is night two?", "who's got the stove?" It knows your trip, looks up what it doesn't, and always asks before it touches the plan. Polite, like a good tent-mate.

the split
Fair weights, private numbers

Every hiker gets an honest carry limit — experience, build, bad knees and all. The crew sees who carries what, never anyone's body stats.

Asked around the fire

(frequently)
Do my friends need accounts?
No. Only the trip organiser has an account. Everyone else joins from the invite link in any browser — they add a name, pick a tent-mate, log their gear, and they're in.
What can Trailmix actually plan?
The whole trip: route and daily camps snapped to real campsites, dates, who's driving and the shuttle, permits, the crew roster and tent pairs, the shared gear list, food and water sized to the miles, and each day's forecast for the spot you'll actually be standing. It all lives on one page the crew can see — and prints to a load manifest when it's time to pack.
Can I use my own route?
Yes — search trails by name, snap trails together at their real junctions in the route builder (side trips and summit detours included), or upload a .gpx file. Trailmix reads the mileage and elevation and sizes food, water, and daily targets to match.
What's this about an AI?
There's a trail buddy in the crew chat. It knows your route, your roster, and your gear list, and it can look up what it doesn't. Ask it anything from "how cold is night two?" to "who's carrying the stove?" If it wants to change the plan — add gear, update the to-do list — it asks first. Always.
How does gear get on the list?
Pick your favourite: reuse the list from your last trip, type items in, or point your phone camera at the pile on the floor — Trailmix names each item and estimates its weight, and you confirm with a tap. A trail-researched checklist (with its sources cited) shows what the crew still doesn't have.
Will it warn us if the weather turns?
Yes. Every day of the plan carries its own forecast — temperature, wind, rain, UV — and Trailmix keeps re-checking it after the plan is made. If the forecast shifts enough to matter, the whole crew gets an email. Coastal routes get tide windows too, so an impassable point never surprises you.
How does the weight split work?
Each hiker gets a carry capacity — roughly 20% of body weight, adjusted for pack experience and things like bad knees. Shared gear and food are distributed so nobody crosses their line. Body stats stay private; the crew only sees the weight each person carries.
What happens when someone bails?
Their shared items flow back into the pool and the plan rebalances instantly across whoever's left. You'll see exactly what needs a new carrier.
Is it free?
Free while we're in beta — every trip you make stays yours. Down the line, planning a trip will stay free for the whole crew.
