Features
What makes Coureo different
Three things we do better than any other letter app.
On-device anonymization
Names, addresses, IBAN, amounts — Coureo replaces them locally with placeholders before anything reaches the cloud.
Deadlines spotted for you
Coureo finds dates and deadlines in your mail and reminds you in time — no calendar babysitting required.
Replies in 11 languages
Understand letters in your language and have Coureo draft a polite or firm reply right away.
Privacy
How we keep your data private
Coureo was built from the ground up so personal data never leaves your device.
Zero-Knowledge by Design
Coureo can't read your data — and neither can we.
