Audecius Exchange

Place, care, connect.
One record each.

Most exchange programmes run on nine spreadsheets and a shared mailbox, and it works right up to the evening something goes wrong. One record per student instead — readable by everybody who is allowed to read it, and by nobody else.

Access is $1.25 per connected code. Every current plan includes 30 days free with no card. An unconnected code is never billed.

Single-use, and written for one named person — the code greets them by name when they create the account.

Everything a season actually needs

Every action carries a consequence class from C0 to C4, visible before you tap it. Three laws can never be switched off.

Matching you can defend on the phone

Every candidate carries its score broken into named dimensions, plus one sentence a coordinator can read aloud to a mother.

The school year

A grade abroad means nothing without its scale

Enrolment across four parties, home recognition always visible, and marks in both scales.

A camp setting at golden hour.
Soft-landing camps

Forty minors, and one honest headcount

Arrivals, rooming, supervision ratios and onward travel — with a refusal when nobody is named.

Host families

One address. One list. One button.

One button that reaches a person who knows your name. The programme pays its connected-code rate; the family receives no separate Audecius invoice.

Trust & data

Leaving is a feature, not a support ticket

EU or US residency, per-field permissions, an append-only log, and an export that works on the day you leave.

Four apps. One record.
And it stays yours.

A student keeps her account when the programme ends — alumni, certificates and personal history survive the organisation.

Who it is for

Four audiences, one system

Sending organisations

Applications, matching, families, documents, incidents and money — instead of nine spreadsheets.

For organisations →

Host families & parents

One address, a list with dates, and a button that reaches a named person. The programme pays for each code a family member connects.

For families →

Schools & partners

Live seats recounted from real placements, your own profile, and one direct line that keeps its answer.

For schools →

Students

One button that reaches a person, a journey with dates, and a wellbeing check-in nobody uses against you.

How safeguarding works →

A student sitting quietly by a window.
“A student must never be able to tell, from her own screen, that her organisation is behind on an invoice.”

The sentence the entire billing ladder is designed around.

An AI that shows its limits, not its confidence

Ariadne reads your own records with your own permissions, drafts the work nobody has time for, and stops at a line she cannot cross. Every action she can take carries a consequence class — visible on the action itself, before you tap it.

Child safety, money and legal consequences are class C4: the tools have no commit function at all. Beside the payment button, the interface says it in four words — Ariadne cannot press this.

What she may and may not do

Ariadne · morning brief
Six students need you today, and three host-family documents expire this week.
Jonas Thaler — unplaced 21 days. Two matches ready.

The floor

Twenty-eight safety capabilities nobody can switch off

Every one of them is written into an organisation the moment it is created. An admin cannot remove them. A plan change cannot remove them. We cannot remove them — the attempt fails with a message that says why.

Billing state, plan tier, office hours and connectivity change everything else. They never reach a student’s help button, the escalation chain, safeguarding logging, or anyone’s right to export their own data.

Machines dun; people rescue. Five steps over sixty days remove convenience and never safety, and the ladder ends in a person rather than a shut-off.
