💡 Trail Naturalist Tip:

Wood Thrushes use their syrinx to sing two notes simultaneously at dusk. Look for them in moist deciduous forest understories foraging in leaf litter.

The 15-Minute Sensory Micro-Expedition

Outdoor Focus

The goal of this open-source build: make the screen the shortest part of your day. Roll a quick nature mission, read it in 20 seconds, lock your phone in your pocket, and let sensory cues guide you.

BIO-DIVERSITY HUNT ⏱️ 15 Minutes Screen-Free

"The Fallen Log Micro-Jungle"

Walk at least 200 paces into wooded canopy. Find a decaying log covered in moss. Spend 10 full minutes inspecting the underneath bark without looking at any screen. Identify 3 distinct non-plant organisms (fungi, millipedes, lichen crusts).

Sensory Checklist:

  • Find damp north-facing bark
  • Inhale the geosmin smell of decomposing oak leaf litter
  • Listen for any woodpecker tapping resonance in the canopy

Why Open AI Matters

Local Weights, Zero Clouds, Deep Woods

Open Source Core

The Problem with Proprietary Cloud AI in the Wild

When you hike deep into a national forest, river valley, or mountain ravine to touch grass, cell signal disappears. Proprietary APIs fail, leaving you stranded with spinning loaders. Worse, your personal GPS tracks and audio recordings get shipped off to distant server farms.

Why TouchGrass AI is Built on Open Weights

📡
100% Offline Trail Independence: Runs locally in the browser via ONNX Runtime / WebAssembly. No network packets leave your device while you are in the woods.
🔒
Total Trailhead Privacy: Your bio-acoustic recordings and run club locations stay in your local browser storage. No surveillance capitalism in the forest.
💵
$0.00 Infinite Execution: Zero token fees, zero monthly subscriptions. You can listen to forest calls all morning without fear of API billing limits.
🦙
Pluggable Local LLMs (Ollama / Llama 3.2): Have a laptop or phone running Ollama? Connect directly to localhost:11434 with one click for rich naturalist field notes with open weights.
