Upload the Excel you already have
Quotes, hours, quality. Just as it is, with no preparation.
It finds what you can't see
Tell it which columns are results and it looks for hidden formulas and columns that give the answer away. It warns you before they inflate the accuracy.
It compares models and tells you whether to trust them
Cross-validation and a plain-language verdict: reliable or not, and why. If an exact figure isn't feasible, it recommends predicting by ranges.
The figure, with its range and similar quotes
How far to trust it and which past quotes back it up. As a PDF to attach.
A new quote, from start to finish
A batch of cream comes in. Helenus gives its cost with its range and says how far to trust it: 77 out of 100 past quotes fell inside theirs. Below, what weighs most in that figure.
Recorded on the real application, with a sample history. Shown in Spanish.
What should I review first? Just ask
It checks your data and models on its own: it flags the quotes that don't add up and tells you what to ask the team. Ask it in plain words and it answers with the exact rows of your history.
Local AI, on your server: your data never leaves the factory. Sample history. Shown in Spanish.
Not just a figure.Why that figure.
A new stainless steel part with six operations, in a sample machine shop. This is what Helenus returns, exactly as it appears on screen.

The figure
€359. What it should cost, learned from what your past quotes really cost.

Its range, and how far to trust it
Between €227 and €524. And not by eye: in 78 out of 100 past quotes the real cost fell inside its range.

What weighs most
Which input moves the figure. Here, the number of operations far more than the material.

The similar quotes behind it
The quotes in your history that most resemble it: what they cost and what the model said without having seen them. So you can defend the price in front of the customer.
And all of it in one PDF, ready to attach to the quote.
It tells you when to trust it.And when not to.
Every model is tested on quotes it did not see in training. That gives its average error and a plain-language verdict for each thing you estimate.

Quote with it. The figure and its range go straight into the quote.
Use it as a reference and check the range before settling on a price.
It tells you plainly and suggests predicting by ranges instead of a figure.

You start with a pilot.No lock-in.
Pilot
On your data, to see if it gets it right. Deducted from the implementation.
