Swiss Trail to Excellence in Logical Learning & Arithmetic
Marking on STELLA is powered by RiteUp, the marking platform of Swiss eduGLOBE AG.
For schools and teachers

Teachers coming

An individual teacher marking her own classes: the same ladder at the same prices, paid by herself. Learners are counted as you register them, with 150 or 250 pages per learner underneath; the same per-exam add-ons at the same prices; monthly card billing through Stripe as an option. Your purse is your own — and if a school later invites you into its workspace, the school's purse pays for school papers, never yours.

Marked by Leo (AI), moderated by Clara (AI), signed by your teacher.

Leo: A computer program, not a person. Named for Leonhard Euler. Clara is a computer program too, not a person.

The ladder for teachers

The marks are never tiered — every plan gets Leo against the memo, Clara's audit, the trial run and its gate, the validation report, the marked PDF in either style, the mark sheet and the totals. Institution is for schools only: it is about departments, budgets and a named moderator.

Standard
CHF 10 per learner a year

150 pages per learner underneath. Marked scripts, the mark sheet and its CSV, totals per learner and per question, the class average, the client desk, script-identifier stickers.

Premium
CHF 16 per learner a year

250 pages per learner underneath. Standard, plus the per-learner feedback note in the memo's own words, the item analysis per question with the common errors, the curriculum-strand breakdown, class and cohort comparisons, the re-mark diff, My hand for every teacher in the school, department budgets and reporting, a parent-ready results pack the school releases.

Prices in CHF; Stripe shows your local currency at checkout.

How does Marking work?

  1. Paper, memo and scripts go in

    A paper, its memo as a PDF and the scanned scripts in a batch.

  2. Leo marks against the memo

    Every tick on the line of working that earned it, with a one-line reason.

  3. Clara checks every mark

    A second program on another model; it speaks only when a check fails.

  4. The trial run and its gate

    A handful marked your way first; at the gate you press Mark the rest.

  5. The teacher decides and signs

    Accept, override with a reason or flag; you approve and sign the batch.

  6. A script is a reference, never a name

    Identifier stickers or a covered name; the platform holds no learner name.

Leo and Clara are computer programs, not people. Marked by Leo (AI), moderated by Clara (AI), signed by your teacher.

The six steps in full

The per-exam add-ons

Reporting depth sold per exam, switched on in a paper's pre-flight with its price shown before any job runs.

Scripts carry an identifier, never a name: cover the learner's name before you scan, or print the sticker sheet. The platform holds no learner name, and nothing a learner writes trains any model.

Join the teachers' waiting list

Marking opens to individual teachers after the first pilots — November 2026. Leave your details and we write to you first. No account is opened, nothing is charged; no learner is named here, and there is no field for one.
