Field Guide: Offline Nature ID

Turn your phone into an intelligent, private field notebook that works completely offline anywhere on Earth—even deep off the grid.

**Field Guide** uses Gemini Nano offline AI to help you identify plants, animals, fungi, rocks, minerals, gems, and clouds on your daily walks, garden visits, or mountain hikes.

### How It Works

1. **Snap a Photo:** A single photo starts the identification.

2. **Add Context:** Capture multiple angles or speak a quick field note about features the camera missed (like texture, scent, or scale) to sharpen the result.

3. **Refine & Chat:** Not sure about a result? Tell Field Guide what doesn't look right, ask follow-up questions, and explore details about your find.

4. **Build Your Journal:** Save sightings locally, review them by date, add personal notes, or export beautiful PDF field pages to share.

### Built for Absolute Privacy

* **100% On-Device Processing:** AI identification, field notes, and chat run entirely on your phone. Your photos never leave your device.

* **Private Location:** Geolocation is strictly optional and used solely to inform regional/seasonal accuracy at the moment of capture. No tracking, no sharing.

### Technical & System Requirements

* Requires a one-time download of Gemini Nano AI (~1 GB+, Wi-Fi recommended).

* **Compatibility:** Gemini Nano AI requires newer, supported hardware. Gemini Nano will not run on older phones.

*Safety Warning: AI identifications can be incorrect. Never rely on Field Guide to decide whether a plant, mushroom, or fungus is safe to eat, touch, or consume.*
