ZarSage Connect · Farm context for ChatGPT and Claude

Your AI knows agriculture.
It doesn’t know your farm.

ZarSage gives ChatGPT and Claude what they lack: the verified state of your fields, from boundaries and soil tests to sprays and safety windows, with sources you can check.

Your morning, in one screen

Weather, the spray window, watchouts and today’s work the moment you open the app.

It asks before it acts

When a recommendation needs a fact only you know, the question waits in Attention. Answer it, or approve the write, even with no signal.

Every field and its cycle

Boundaries, crop stage, soil status and applications, linked to the right field.

News for your crop and country

A daily digest of what matters to what you grow and where. Each story carries its sources and stays readable offline.

Works with no signal

Log work in the field; it’s saved on the phone and uploads in order when you’re back in range.

Map your field boundary

Tap the map to place corners; the area is computed for you.

Start with a real job

Three useful first prompts.

The assistant will retrieve what ZarSage already knows, ask only for missing information, and request confirmation before it writes.

Set up my farm

Set up my farm in ZarSage. Start with my field and its exact boundary, then save any soil lab results, resource notes, and source links I provide. Ask only for information that is still missing, and show me each change before saving it.

Analyze a field

Analyze my field named [field name]. Use its crop and work history, soil evidence, recent and forecast weather, and available satellite observations. Show the evidence, sources, confidence, and data gaps, using charts, maps, tables, or images where they help.

Plan a crop cycle

Help me plan the next crop cycle for [field name]. Use ZarSage's farm evidence and current crop-suitability data, ask about any constraints that materially change the plan, and present a complete draft with tasks and reasoning before asking me to confirm it.
