LineSpec

A phone-camera colour check for cleaning quality. On-site, offline, logged.

In flight

LineSpec turns a standard phone into a calibrated colour reader. A member of staff photographs a sample where the work happens, and CIEDE2000 colour matching grades it against your reference scale, returning a stage and a confidence rather than a guess. An independent AI second opinion checks the capture for glare, foam, or a bad shot. No lab, no colorimeter, no waiting.

Cleaning quality is often judged by eye. Two people disagree, the lighting changes the call, and a borderline result slips through on a busy shift, with no record that the check ever happened.

Sending samples to a lab is accurate but slow and costly, and it tells you about a problem hours after the moment you could have caught it.

Reads colour, not opinion

Point a phone at the sample. LineSpec corrects for lighting with a white-balance calibration, rejects glare, samples through the glass, and grades the colour with CIEDE2000 against your own reference.

An AI second opinion

An independent vision check re-reads each result and flags capture problems like glare, foam, an empty vessel, or blur, so a bad photo does not become a bad pass. It only ever adds a safety net.

Works without signal

Built as an installable PWA, so it runs in a cellar or a back room with no connection. The full check works offline.

Every reading logged

Each check is recorded with its result, confidence, and timestamp, and the dashboard exports to CSV or a printable report. Quality becomes an audit trail, not a memory.

Built for teams that check cleaning quality by eye today and want a faster, consistent, recorded call. The colour engine is general; the first build is tuned for line-cleaning and draught-dispense hygiene.

Thresholds are set against your own reference scale and calibrated per site, so the check reflects your specification, not a generic one. Where a sample matches nothing on the scale, LineSpec says so rather than forcing a result.

Does it need special hardware?

No. LineSpec runs in a standard phone browser. The accuracy comes from white-balance calibration and CIEDE2000 colour matching, not a dedicated colorimeter.

How does it grade a sample?

It matches the sample colour against your reference scale using CIEDE2000 and returns a stage with a confidence score. When nothing on the scale is close enough, it flags the reading rather than guessing.

What does the AI add?

An independent second opinion. It re-reads each result and flags capture problems like glare, foam, or a bad shot, so a poor photo does not pass as a clean sample.

Does it work without signal?

Yes. It is an installable PWA and the full check runs offline, which matters in a cellar or back room.
