The problem

A month of shifts is not a spreadsheet problem.

Coverage, rest, caps, night blocks, time off, fairness. Dozens of rules that all interact, for every provider, every day. By hand it takes days and still feels unfair.

Why Coranth

Most tools guess. Coranth solves.

Most tools

They guess, then hope

A language model can draft a schedule. It cannot promise every coverage minimum, rest period, and cap is met. It fails quietly.

Coranth

It solves, or it tells you why

An optimization engine meets every hard rule, or names what is blocking the month. AI only handles the language. The math builds the schedule.

Hard rules are guaranteed, not hoped for.

Coverage, rest, caps, and night blocks are met exactly. When a month cannot be built, Coranth says why and helps you negotiate a fair way through. It never quietly breaks a rule.

How it works

From plain language to a published month.

1

Set your rules

In plain language or per provider. Coranth warns you when two rules conflict.

2

Build the month

Every shift assigned under your hard rules, the soft ones balanced. If it cannot be built, you see why.

3

Publish and share

Your team sees their shifts, requests time off, and trades shifts from their phone.

What you get

Everything a group needs to run its own schedule.

Fairness you can show

Nights, weekends, and holidays spread evenly, with the count on the table.

Providers self serve

Requests, preferences, and trades from a phone. You approve. Nothing changes without you.

Hard rules, guaranteed

Met exactly, or the month is reported unbuildable with the reason. Never quietly broken.

Manual control when you want it

Place shifts by hand, lock the ones that matter, and let the solver fill the rest.

Publish once

Personal schedules, calendar files, PDFs, and a change history from one published record.

Built for real groups

Many sites, many provider types, monthly or two week periods. Any size.

Fairness

Fair is not a feeling. It is a number.

Nights, weekends, and holidays spread evenly among the people who do not prefer them, and the count shown to everyone. When the math is on the table, the argument ends.

Coranth was built by someone who has spent nights in the department and days holding the schedule together.

A practicing emergency physician and physician administrator.

Why it is different

Built by a practicing emergency physician and physician administrator.

For independent physician and allied health groups, one site or many. No spreadsheet, no black box, no guessing.

1

Say it in plain language

"Chen cannot work nights on Mondays. Give Davis October 3 to 10 off." Coranth shows what it understood before saving anything.

The whole month in about a minute. If it cannot be built as asked, you get complete alternatives and what each one gives up.

Publish

Each provider gets their month by email, as a PDF and a calendar file. Swaps happen between providers, rules still enforced.

Compare

Some tools show the schedule. Coranth builds it.

What you are choosing between, with public prices where they exist.

Publishers

Amion and its kind

Displays a month somebody built by hand. Cheap, and it should be: the hard part still happens at your kitchen table.

Amion lists at $449 a year. The nights spent building the month it displays are not included.

The builder

Coranth

Builds the month from your rules. Requests, swaps, equity, and publishing included. Live in a week, your data comes with you.

One flat price per group. No per provider fees, no implementation fee, no quote.

Enterprise builders

QGenda, Lightning Bolt

You pay health system prices for a solver: per provider licensing, a quote you have to ask for, months of implementation. And their own reviewers say the month still needs finishing by hand after the solver runs.

Third party estimates put a ten provider group near $49,000 in year one. Expensive, slow, and you still do the last mile.

Prices from public listings, third party estimates, and published user reviews as of September 2026. Not offers from those vendors.

Pricing

One price. Every provider. No surprises.

Per group, per month. Never per provider.
