Frostline: a garden planner that runs on Gemma, on your laptop, so you can touch grass

Description and use

Frostline is a local garden planner that uses Gemma 3 via Ollama to generate a concise coaching note based on frost dates, producing a printable field card for outdoor use.

Problem

Gardeners need a quick, local tool to decide what to plant each week based on frost dates and receive a concise coaching note without relying on external servers.

Outcome

Frostline provides deterministic planting windows and a concise coach note entirely on the user’s machine, eliminating external dependencies and privacy concerns.

Workflow

• Enter today’s date, last spring frost, and first fall frost in MM‑DD format
• Planner.js calculates open, closing‑soon, and upcoming planting windows
• Server requests Gemma 3 (via Ollama) to write a short coach note about the listed tasks
• UI displays grouped checklist, coach note, and a print‑friendly field card
• Print the card, close laptop, and go outside

Evidence

Frostline works out which sowing, indoor‑starting and transplanting windows are open right now, which are closing within a week, and which open within two.

Source

A local open-weight model, Gemma 3 served by Ollama, then writes a short coach note about those tasks and ends with one thing to do today with your hands in the soil.

There is no hosted demo, and that is deliberate: Frostline is local-first, so the model runs on your own machine rather than on a server I pay for.
