Your morning, in one screen
Weather, the spray window, and today’s work the moment you open the app.
ZarSage Connect · Farm context for ChatGPT and Claude
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.
00 · In the field
Four jobs a farmer does before lunch, recorded on the real app. Every one of them writes to the same record.
Weather, the spray window, and today’s work the moment you open the app.
Boundaries, crop stage, soil status and applications, linked to the right field.
Log work in the field; it’s saved on the phone and uploads in order when you’re back in range.
Tap the map to place corners; the area is computed for you.
01 · One record, three surfaces
The record lives in ZarSage. Everything else reads from it (your phone, your assistant, your team’s console) under the same permissions, with the same evidence attached.
The record in your pocket: today’s work, attention items and decisions, captured with no signal, synced when it returns.
Ask naturally. The assistant retrieves permitted farm context, attaches the evidence, and asks before it writes.
Fields, people, roles and assets for the whole operation. Session-gated administration that connectors cannot reach.
ZarSage farm record·permissions · source evidence · execution receipts · tenant isolation
Fields and boundaries, crop cycles, soil lab results, tasks, scouting, interventions, resources, and confirmed farm memory, all linked to the right field.
Combine forecasts, weather history, satellite imagery, NDVI, soil evidence, and your own records. The assistant can present the result as a chart, map, table, image, or report.
Draft crop plans, tasks, scouting work, interventions, resources, and reports. Review proposed changes before allowing write actions; supported planning workflows add a server-side confirmation step.
02 · MCP · ZarSage Connect
Paste one URL into ChatGPT or Claude. Sign in with Google or an emailed code, approve only the scopes you want, and revoke from your assistant’s connector settings whenever you choose. The mobile app shows the same endpoint and what is connected. Step through it below.

Ask naturally in ChatGPT or Claude. ZarSage finds the permitted farm context, attaches the evidence, and brings a grounded answer back to the conversation.
One farm record. Any assistant.
Your farm record, available wherever you work with AI
03 · Trust the answer
Fluent answers are cheap; answers you can check are not. Every claim carries its sources, timestamps, confidence and known gaps, and nothing is written without your approval, whether the request comes from ChatGPT, Claude, or a phone in a field with no signal.
04 · Setup
Claude works on a free account and is the quickest route. ChatGPT needs Developer mode. Once you have the app, it shows the same endpoint. Menu names vary by rollout and workspace policy.
Recommended for individual farmers. Claude supports custom connectors on every plan. Free accounts can add one; Team and Enterprise owners must add ZarSage for their organization first.
ZarSage is free during early access. Each account can register up to three fields, each from 0.01 to 300 hectares. No ZarSage subscription or payment card is required. Assistant availability and permissions follow each host's account and workspace settings. Stuck on a step? Email us and a person will help.
05 · Start with a real job
The assistant will retrieve what ZarSage already knows, ask only for missing information, and request confirmation before it writes.
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 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.
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.
