About Us

A small, independent project building free, privacy-first planning tools for hikers, trekkers and overlanders.

Our mission

AI Outdoor Trip Planner exists for one reason: to give every hiker fast, trustworthy numbers before a trip — without forcing them to create an account, hand over their data, or wait for a page to phone home.

Every tool on this site is free, unlimited and runs entirely in your browser. There is no API key to manage, no server round-trip for your calculations, and no tracking profile built from your routes. We believe planning software should feel invisible — open a page, get an answer, keep walking.

Our commitment Free forever · No sign-up · No data uploaded to our servers · Formulas shown on every result page.

What we offer

The site currently ships 16 planning tools and 15 in-depth guides, covering the full loop of trip preparation:

Itineraries — Multi-Day Trip Planner, Group Trip Planner, Rest & Pacing Planner, Elevation Profile, Daylight Planner.
Body & fuel — Calories & Hydration, Hydration Calculator, Food & Calories Planner, Pack Weight Calculator.
Gear & safety — Layering Guide, First-Aid Kit Builder, Group Gear Optimizer, Emergency Contact Card.
Numbers — Pace & Time (Naismith), Outdoor Unit Converter, Trip Cost Estimator.

Each result page shows the exact formula behind the number and its sources, so you can audit it instead of trusting it blindly.

How it works (technically)

This is a static website. The HTML, CSS and JavaScript you download are the entire application. When you tap Calculate, the math runs locally on your device — distance, climb, calories, water, cost, everything. Nothing you type is sent to a server, stored in a database, or associated with your identity.

Your preferences are kept on your own device using the browser's localStorage: the language you chose, the tools and articles you heart, and the trip plans you save in the planner. Clearing your browser data clears them — that is the trade-off for not having accounts.

Editorial stance & safety

These tools are planning aids, not professional advice. Naismith's Rule, MET-based calorie estimates, and hydration formulas are decades-old approximations; they cannot account for your fitness, the weather on the day, a broken boot, or a storm rolling in.

Treat every output as a starting estimate. Always cross-check with official trail information, current forecasts, your own experience, and — for anything serious — a qualified guide or medic. The mountains do not read our spreadsheets.

Outdoor risk notice Hiking and backpacking carry real risk of injury and exposure. We provide estimates for education and planning only. You are responsible for your own safety, your group, and the choices you make on the trail.
