The project

A research project, brewed into a product.

Tea is Sri Lanka's signature export, yet fresh leaf quality is still judged by eye, and growers rarely see why their leaves fetched the price they did.

TeaOptima began as an academic study into AI-driven tea leaf quality assessment, and grew into a full mobile platform that puts that science directly into the hands of the people who grow, collect and process Ceylon tea.

A single photo is all it takes. The app grades the leaves, explains its decision factor by factor, forecasts how the quality will decay over the coming hours, and pairs the result with indicative Colombo Tea Auction pricing.

  • A grade you can trust and verify. Every result comes with the AI's reasoning.
  • Built on peer-reviewed research, validated on real Sri Lankan harvests.
  • One app for the whole chain: growers, collectors, factory officers and buyers.

What you can do

Everything a grade should be: fast, fair, explained.

Six capabilities, one app, designed end-to-end for the realities of the Ceylon tea trade.

Instant AI Grading

Point your camera at fresh tea leaves and get a quality grade in seconds, powered by a computer-vision model trained on a real-world dataset of fresh tea leaves.

Explainable Results

No black boxes. TeaOptima shows exactly which conditions are protecting or degrading your leaf's quality over time, with clear visual contribution bars.

Quality Decay Forecast

Know how long your harvest will hold its grade. Our decay model predicts quality over time so you can plan collection and transport.

Live Price Guidance

Indicative Rs/kg rates aligned with Colombo Tea Auction averages, fully editable so your numbers always match your market.

Trilingual by Design

Every screen, every AI explanation and every report, available in English, Sinhala and Tamil. Built for everyone in the supply chain.

Professional PDF Reports

Export beautiful, shareable quality reports in your language of choice, ready for factories, brokers and buyers.

How it works

From leaf to insight in three steps.

No training, no lab equipment, no waiting. If you can take a photo, you can grade your harvest.

01

Capture

Snap a photo of your fresh tea leaves with your phone, whether in the field, at the collection point, or at the factory gate.

02

Analyse

TeaOptima's AI grades the leaves instantly and explains its reasoning: which factors helped, which hurt, and by how much.

03

Act

See how quality will decay over time, check indicative auction prices, and export a professional PDF report, all in your language.

The intelligence inside

Four kinds of intelligence, one photo.

Tap through what actually happens the moment you grade a leaf with TeaOptima.

Computer vision, built for Ceylon leaf

Point your phone at a handful of fresh leaves and TeaOptima's vision model returns a Tier 1 - Tier 4 quality grade in seconds. No lab, no waiting, no guesswork. Built for everyday plucking on Sri Lankan estates.

  • Runs on an ordinary phone camera
  • A full Tier 1 to Tier 4 grade in seconds
  • Rejects photos that aren't a tea leaf

The story

Built in Sri Lanka, for Sri Lankan tea.

TeaOptima started with a simple observation - the people who grow the world's finest tea often have the least visibility into how its quality is judged, and what it's truly worth.

What began as a peer-reviewed research project on AI-driven leaf quality assessment has grown into a complete product - a grading engine that explains itself, a decay model that forecasts the clock ticking on every harvest, and an interface that speaks all three of Sri Lanka's languages.

Every photograph on this site was taken on the same estates and in the same factories where TeaOptima was tested and refined - because this project belongs to the tea country it was built in.

The science

Backed by peer-reviewed research.

TeaOptima isn't a black box. The grading and forecasting methods are published and peer-reviewed, so anyone can read the science for themselves.

The science behind TeaOptima: a two-stage AI pipeline that first grades a photographed tea leaf into four quality tiers with a fine-tuned YOLOv8 vision model, then forecasts how that grade will decline day by day across a 15-day window using the leaf's age and local weather. An explainable-AI layer (SHAP) ranks the conditions driving each day's change, with humidity and temperature chief among them, and turns them into plain-language harvest recommendations.
