schedule

Scheduling eats up hours

Building schedules by hand costs hours every week. One change triggers a dozen follow-on conflicts.

gavel

Compliance risk

Rest periods, qualifications, pay premiums, public holidays. One overlooked value quickly becomes a costly mistake.

cloud_off

Forced cloud & lock-in

Personal data on someone else's servers, dependence on a single vendor. Sensitive industries can't afford that.

The promise

You stay in control.

Over your data, over the AI behind it, and over your rules. Three reasons why Klacks is different from any cloud solution.

shield_lock

Your data

On-Premise & Open Source

Klacks runs on your own infrastructure — not a single record leaves the building. 100% open source, no vendor lock-in. Your data belongs to you, today and in ten years.

smart_toy

Your AI

Klacksy — with your choice of model

An AI assistant you control by voice. You choose the LLM yourself — from OpenAI, Anthropic & co. to a local model. No forced choice, no lock-in with an AI provider.

tune

Your rules

Pre-configured & fully customizable

Rules, calculations, and public holidays come pre-configured for your country, canton, and municipality. You can adjust everything yourself — no consulting days, no waiting for the next release.

The combination almost no one offers

AI and full data sovereignty. At the same time.

Klacksy can run on a local language model. That means an assistant that builds schedules, creates staff records, and operates the app by voice — without a single personnel or patient record ever leaving your building. Exactly what hospitals, home care, and security services need.

Let the machine build the schedule

An evolutionary algorithm checks thousands of variants in seconds and finds the best balance of coverage, cost, and satisfaction.

auto_awesome

One-click auto-scheduling

The tedious part — done in seconds. The algorithm respects every constraint: labor law, qualifications, availability, and travel distances.

route

Route & Tour Optimization

For mobile operations: routes optimized with an ant colony algorithm — by car, bike, on foot, or mixed. Ideal for home care, security patrols, cleaning, and logistics.

hub

Modular scheduling without double-booking

Share staff across departments without conflicts: schedule sheets hold references instead of copies. A change is instantly visible everywhere — double-booking becomes impossible.

event_busy

Absences at a glance

Vacation, sick leave, and custom absence types at a glance as a Gantt chart. Export to PDF with a single click.

checklist

Approval workflow

From draft through confirmed and approved to completed. Each stage locks further editing — with group-based access rights.

grid_view

Interactive schedule grid

A powerful time matrix: move shifts by drag & drop, and changes appear in real time for everyone involved.

Divide and conquer

Large schedules stay manageable

Instead of juggling one unwieldy master schedule, break it into small, clear sub-schedules — and Klacks automatically keeps everything in sync.

dashboard

Step 1

Split it up

Break the large schedule into manageable areas — by team, department, or location.

how_to_reg

Step 2

Schedule once

Anyone working across multiple areas is scheduled only once — and appears correctly everywhere, automatically.

sync

Step 3

Automatically in sync

A single change is instantly current everywhere. Double-booking is ruled out — with no manual upkeep at all.

Rules & Calendar

A calendar for every reality

Public holidays and rules are a patchwork in Switzerland — they vary by canton, and sometimes even by municipality. Klacks masters exactly what simple tools fail at.

  • place
    Down to municipality level Country, region (canton, state, département), and municipality — pre-configured to fit.
  • layers
    Mix calendars Multiple countries at once — for example Geneva and the US, for a business with trading partners there.
  • tune
    Enforced or just informational You decide per calendar whether a public holiday affects hours & pay premiums — or just appears as a reminder.
Public holiday rules
Public holiday rules in Klacks: holidays by nation and region – Germany, the US (Alaska), and the Swiss cantons of Lucerne, Jura, Glarus, and Appenzell

Real rules from Klacks: one list mixes public holidays from several countries and individual cantons — freely extendable.
