I built an offline AI that knows your last frost date, no internet, no API

Description and use

FrostWise is an offline tool that predicts the last spring frost date and provides planting advice without internet or API access.

Problem

Gardeners in areas with spotty signal cannot reliably get last spring frost dates from online services, risking crop damage.

Outcome

FrostWise provides accurate, offline last frost predictions and crop advice, enabling gardeners in low‑signal areas to plant safely.

Workflow

• Select location or input climate data
• Choose crop
• FrostWise runs TabPFN‑v2 locally to forecast last frost date
• Gemma 3 locally generates plain‑language planting advice
• Display date, range, and advice to user

Evidence

FrostWise answers one question honestly: when does the cold let go where you are, and what should you do about it.

Source

Two open-weight models, no API key, no account, nothing leaves the machine.

Source

Clone it, python run.py, and it is on localhost:8077. The first forecast caches the model weights once; after that you can pull the network cable and it still works.
