Farm intelligence for your AI
Give your AI the full story of your farm.
ZarSage gives ChatGPT and Claude secure access to the context they need to help: your fields, crop cycles, soil results, weather, satellite evidence, work history, and farm resources.
Works in: ChatGPT, Claude, Claude Code, Codex, and remote MCP clients.
Your farm speaks. Your assistant understands.
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

One farm record
Better decisions in every assistant.
Stop rebuilding farm context in every conversation. ZarSage keeps the authoritative record; your assistant retrieves the right evidence when it needs it.
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.
Trust the answer
Evidence you can inspect. Control you can keep.
Your assistant handles the conversation and presentation. ZarSage protects the farm record, permissions, source evidence, and execution receipts behind it.
Important claims include timestamps, units, provenance, confidence, and known data gaps.
Write tools require separate permission. Some workflows enforce a server-side confirmation step; your assistant may also ask before acting.
Each account and organization is checked on every request; files remain private and tenant-scoped.
Sign in with Google, review the requested scopes, and disconnect the assistant whenever you choose.
Connect ZarSage
Paste one URL. Sign in. Start farming.
The URL flow below adds ZarSage privately through Developer mode: ChatGPT calls it a custom app, while Claude calls it a custom connector. Menu names and capabilities can vary by account 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.
- Open Claude web at claude.ai. On Free, Pro, or Max, open Customize → Connectors, then select Add → Add custom connector.
- Team or Enterprise owner: open Organization settings → Connectors, select Add → Custom → Web.
- Name it "ZarSage," enter the server URL: https://app-api.zarsage.ai/v1/mcp. Then select Add.
- Continue with Google when the sign-in window opens. If it does not appear, select Connect on the ZarSage row. Team or Enterprise members start here: open Customize → Connectors, find ZarSage, then select Connect.
- Enable ZarSage for a conversation from + → Connectors.
ZarSage has been tested successfully on ChatGPT Free and paid accounts where Developer mode is available. OpenAI officially documents full read/write MCP for Business, Enterprise, and Edu workspaces; individual accounts may see Developer mode as availability expands, so enabled actions can vary by account rollout and workspace policy.
- Open ChatGPT web at chatgpt.com. On Pro, or a Free account where the option appears, open Settings → Apps → Advanced settings and enable Developer mode.
- Business, Enterprise, or Edu: on ChatGPT web, a workspace admin enables Developer mode and grants access; then open Apps → Create.
- Select Create, name it "ZarSage," and enter the server URL: https://app-api.zarsage.ai/v1/mcp.
- Select Scan tools, continue with Google when authorization opens, wait for the scan, then select Create.
- In a new chat, enable ZarSage from the tools menu or mention ZarSage in your prompt.
ZarSage is free during early access. Each account can register one active field 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.
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 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.
Copy promptAnalyze 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.
Copy promptHelp 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.
