1–3 weeks in spreadsheets
Excel, aSc, NIKA or FET. Any change in teaching load means half a day of rework.
Everything a real school has
Subgroups and streams, double lessons, alternating weeks, terms, part-time teachers.
Online school timetabling
A timetable that adds up.
Built in minutes, never breaks the norms, tells you what’s in the way — and after a substitution changes only what it must.
For private schools, lyceums and school networks. In the browser and on your phone.

1st period
Every deputy head knows this
The timetable eats up August and falls apart in September
Substitutions wreck the grid
A teacher falls ill, a part-timer swaps a day — and the timetable turns into patches full of gaps.
You learn about norms from the inspector
SanPiN compliance is checked by hand, or not at all. Violations surface when it’s too late.
No idea why it won’t fit
The software says “impossible” and doesn’t tell you which rule is in the way.

How it works
Three steps from teaching load to a finished timetable
Upload your data
Teaching load, classes, rooms and teacher preferences. Your Excel file or an export from aSc or FET will do.
.xlsxaSc XMLFETCSV
Get a scored timetable
In minutes. Gaps, load balance and norms are visible at once. If something can’t be built, it tells you why.
Edit and publish
Move lessons by hand or enter substitutions. Recalculation changes as little as possible.

What A Generator adds
We’ll move your data over from your current software — no starting from scratch.
Excel
A timetable in minutes instead of weeks, and a clear score of how good it is.
NIKA and desktop programs
The cloud instead of a single computer, access from your phone, automatic norm checks.
FET
Optimization with a quality score, works in the browser, recalculates substitutions, support in Russian and Uzbek.
aSc, Untis
An API for embedding, health norms out of the box, explanations of why it won’t build.

For LMS and SIS platforms
Your platform shows the timetable. Let it build it, too.
Building your own generator takes months. Plug in the API for generation, validation and substitutions, and embed the widgets under your own brand.

An audit of your current timetable
Send us your timetable and teaching load as they are. We’ll run them through A Generator and show you:
- how many gaps teachers have, and where;
- which SanPiN or UzSanPiN norms are broken;
- how far it is from the best possible one;
- what to improve without touching teacher preferences.

Questions and answers
What people usually ask
How do you handle school data?
The engine works only with codes: T-07, 7B, Rm 214. Teacher and student names stay with you. Everything you upload can be exported back in open formats.
How much does it cost?
The audit is free. The subscription depends on the number of classes and features — we’ll quote it after the audit. Platforms using the API get separate terms.
How long does onboarding take?
The timetable itself is built in minutes. Most of the time goes into collecting teaching load, rooms and preferences. If they’re already in Excel, aSc or FET, it goes faster.
What if some data is missing?
A Generator shows exactly what’s missing and which rules contradict each other, for example “a teacher has more lessons than free slots”.
Can we switch to another program later?
Yes. The timetable and the source data export to Excel, PDF, calendar and the aSc and FET formats.
Does it work on a phone?
Yes, the workspace runs in the browser on a computer, tablet and phone. Nothing to install.
