The mobile home for CAS and Ask Source

Source's mobile app for greenhouse growers. Take crop measurements and ask Source questions about your cultivation data, right from your phone. Available now on iOS and Android.

Source App has two capabilities:

Crop Assessment System (CAS)

CAS turns manual plant scouting into structured, consistent data capture that feeds straight into your harvest forecast and plant balance metrics.

Ask Source

Ask Source turns your cultivation data into a conversation. Ask a plain-language question about your greenhouse's quality, climate, or status, and get a straight answer in seconds.

Crop Assessment System (CAS):

Replaces the Source Plant App for tomato growers, with faster, more consistent measurement capture.

Simply scan. QR-tag each truss and log quick observations as you walk the greenhouse.
Built for the whole crop cycle. Captures data from first flower to harvest, so nothing gets estimated after the fact.
Feeds your forecasts. Flows straight into Harvest Forecast and Plant Balance Metrics for a cleaner, more accurate picture.
Works offline. Keep measuring even without signal in the greenhouse; it syncs when you're back online.

Rolling out to tomato growers from September 2026.

Ask Source

Ask Source is an AI growing assistant, built into the app and trained on your cultivation data, not a generic chatbot.

Ask anything, anytime. "Any active quality issues right now?" "What was my 24-hour temperature yesterday?" "What's the status of my operation?" — get a straight answer in seconds.
Grounded in your data. Draws on your own measurements, history, and forecast, plus Source's shared agronomic knowledge.
Get standing reports, not just answers. Describe a report once, a weekly summary, a daily digest, and it keeps arriving on your schedule, right in the chat.
