Why try it

A real trial, not a demo

Everything unlocked

No feature gates. Calibration, grading, and certificates all work exactly as they do in a paid license.

Your own scanner & samples

Calibrate against the flatbed scanner you actually use, and grade real samples from your own floor -- not a canned sample set.

Works offline

Calibration, scanning, grading, and certificate generation all run locally -- no dependency on a connection to use it day to day.

No card, no surprise charge

Nothing is billed to start a trial. When 7 days are up, it simply stops issuing new certificates until you activate a license.

Who it's for

Built for the people grading rice every day

Rice millers

Check outgoing batches against specification before they leave the mill, without sending samples out to a lab.

Exporters & traders

Hand buyers a sequentially numbered certificate instead of a report they have to take on trust.

Quality control labs

Replace manual grain-by-grain counting with consistent, repeatable per-grain measurement.

Independent analysts

Run Grainer on your own workstation and issue certificates under your own name, no lab required.

Trial FAQ

Frequently asked

Do I need a credit card to start?

No. Download, install, and Grainer starts a 7-day trial automatically -- no card, no signup required to install.

Is the trial per workstation or per company?

Per workstation. Each machine you install Grainer on gets its own 7-day trial, tied to that machine.

What happens when the trial ends?

Grainer stops issuing new certificates until you activate a license key. Everything you've already scanned, graded, and certified stays on your machine.

Does my trial data carry over if I buy a license?

Yes. Activating a license key on the same install doesn't reset anything -- your calibration, scans, and certificates all stay exactly as they were.

What's the difference between the trial and a paid license?

None in functionality -- the trial has full access. The only difference is that it runs for 7 days on one workstation instead of continuing under a license. See pricing for annual vs. one-time plans.
