Give it the batch
Paste a column, drop a CSV, or hand it JSON. No schema, no field mapping, no account. It reads what you gave it and tells you how many readings it found.
QUANTA · measurement utility
One number you can defend.
QUANTA takes a batch of raw measurements and returns a single figure with its tolerance attached. That is the entire product.

QUANTA is a fictional brand. This is a template demonstration, not a product you can buy.
01 — The problem
Spreadsheets average things that should not be averaged.
A column of readings hides the thing you actually need to know: how far apart they were. Take the mean and the spread disappears into a figure that looks equally confident whether your batch agreed to four decimal places or barely agreed at all.
QUANTA does one thing instead. It reads the batch, reports one figure, and prints the interval that figure is good for — so the number you take into the room carries its own tolerance.
- It will not extrapolate beyond the batch you gave it.
- It will not fill a gap in your readings with a guess.
- It will not hide a wide interval behind a rounded figure.

What it does, in three moves.
02 — Mechanism
02
It weighs the spread
Every reading is kept. The tool computes the central figure and the interval around it from the batch itself — nothing is smoothed, nothing is imputed.
03
You get one figure
One number, one interval, and the count it came from. Copy it out as text, or keep the whole working so somebody else can check it.
The same twelve readings, three times.

Three things the method does, stated plainly.
There are no customer logos on this page and no usage figures, because QUANTA is a fictional brand built to demonstrate a template. What is described above is what the tool would do, and it is the only kind of claim worth making.
Method
How the interval is computed
From the batch itself: the spread of your own readings, at 95%. No population assumption is borrowed from anywhere else.
Method
What happens to outliers
They stay. A reading far from the rest widens the interval, which is the honest outcome — it is never quietly discarded to tighten the figure.
Refusal
When a batch is too small
It refuses and says so. Below three readings there is no interval worth printing, and a figure without one is the thing this tool exists to avoid.

Four questions, answered
What exactly is the interval?
A 95% interval computed from the spread of the readings you supplied, and nothing else. It is printed next to the figure because a figure without one is not defensible.
Does it clean my data?
No. Every reading you give it is used. A distant reading widens the interval rather than being quietly dropped, which is the honest outcome.
What happens with a very small batch?
Below three readings it refuses and says why. There is no interval worth printing from two numbers.
Is any of this real?
The template is. QUANTA is a fictional brand written to demonstrate it, so there is no product to buy and no account to make.
