The past year has been the biggest in Horarium's history. We rebuilt parts of the engine, added a modern AI assistant, and smoothed out dozens of everyday details, all with one goal: getting you from an empty account to a finished, conflict-free timetable in less time and with less frustration.

If you'd rather see it than read about it, you can now open a demo account preloaded with a real school and generate a timetable in seconds, with no data entry required. Here's everything that changed.

A faster, smarter solver

Horarium already produced solid, conflict-free timetables, but we saw room to make them faster and better, especially for the most demanding schools. This year we reworked the core of the engine to do exactly that.

What you get: timetables that generate faster and come out even cleaner, with constraints that are satisfied more consistently. The more complex your school's requirements, the more the difference shows.

Subgroups and divisions, rethought

We rebuilt the subgroup model from scratch. You can now define divisions per class and create shared lessons that include any combination you need: one subgroup, several subgroups, or whole classes together.

What you get: you can model real situations the way they actually work, directly and naturally, whether that's foreign-language groups, electives, lab splits, or combined lessons across classes.

An AI assistant, built in

Horarium now has an AI assistant that answers both kinds of questions people actually ask: how-to questions about using the app ("how do I set up X", "what does error Y mean") and the everyday non-technical ones about purchasing, accounts, and billing.

What you get: instant help, in your language, without waiting on support. It's trained on our rewritten help guide, so the answers stay accurate and specific to Horarium.

Compact view with drag & drop

There's a new compact view that shows the whole institution's timetable at once, with every class, teacher, and room side by side on a single screen. You can move lessons around by dragging them directly on the grid, from one slot to another.

What you get: the full picture in one place, so you can spot and fix issues across the whole school without jumping between pages. Manual adjustments are fast and intuitive too, so fine-tuning a generated timetable feels the way it should.

Excel-style bulk lesson entry

A new spreadsheet-style page lets you enter lessons in a grid, the way you'd work in Excel. Move between fields with the keyboard and duplicate rows in a click, so you can fill in lesson after lesson without reaching for the mouse.

What you get: much faster setup, especially for large schools with hundreds of lessons. Type, tab, duplicate, and you're through the list in a fraction of the time.

DEMO mode with preloaded data

You can now open a demo account that comes preloaded with a complete example school. Generate a timetable, try the constraints, and explore the views, all in a few seconds and without entering anything yourself.

What you get: a real feel for how Horarium works in just a minute or two. It's the fastest way to see whether it fits your school. Try the demo now.

New teacher constraints

Two constraints teachers have been asking for: a maximum number of gaps per day and per week, and a maximum number of building-to-building transfers per day and per week.

What you get: more humane timetables. Teachers spend less time waiting between lessons and less time walking between buildings, and you get finer control over quality for demanding schools.

Unavailable periods, visible in the timetable

Unavailability for teachers, groups, and rooms is now shown directly in the timetable, and it updates as you move lessons around.

What you get: you see conflicts before you make them. No more dropping a lesson into a slot that turns out to be unavailable and finding out later.

Redesigned teacher and group pages

We reworked the flows for adding and editing teachers and groups. You can add them quickly from a list or by name, then configure them individually or in bulk.

What you get: fewer clicks and a smoother setup, whether you're adding one teacher or an entire staff.

A completely rewritten help guide

We rewrote the help guide from scratch, with more than 200 new articles built around concrete examples and step-by-step scenarios instead of vague descriptions.

What you get: you can find the answer yourself, fast. And because the new AI assistant is built on this same guide, better docs mean better answers everywhere.

---

That's the 2026 release in short: a stronger engine, a modeling system that matches how schools really work, and a lot less friction from first login to finished timetable.

The best way to feel the difference is to try it. Open a demo account and generate your first timetable in seconds.
