Try Grainer on your own scanner and samples.
Full functionality, one workstation — a real trial, not a limited demo. Grainer runs on 64-bit Windows 10 and 11.
No card required · trial just ends, nothing is ever auto-charged
Everything unlocked
No feature gates — calibration, grading and certificates work exactly as in a paid licence.
Your scanner, your samples
Calibrate against the flatbed you actually use and grade real samples from your own floor.
Works offline
Calibration, scanning, grading and certificates all run locally.
No card, no surprise charge
Nothing is billed to start a trial. It simply stops issuing new certificates until you activate a licence.

Go further
When you are ready, pick a plan to keep going past the trial.
- Rice millers. Check every outgoing batch against specification before it leaves the mill — no sending samples out to a lab.
- Exporters & traders. Hand buyers a full analysis report and numbered certificate instead of numbers they have to take on trust.
- Quality labs. Replace grain-by-grain hand counting with repeatable per-grain measurement.
- Independent analysts. Issue reports under your own name from one workstation — no lab required.
