Alteryn

Spatial memory mapping for EMDR and reflection

Web E2E encrypted Offline capable

A private tool for mapping memory and emotion in space. Built to support EMDR therapy and personal reflection by creating interactive landscapes that represent the inner terrain of experience.

Raise and lower ground, add notes, and trace how certain memories feel in relation to one another—as hills, valleys, or paths across a map that only you can see. Everything is encrypted before it leaves your device. The server can't read it, and even when you collaborate or share parts of a map, only the people you choose can decrypt it.

Features

Spatial memory mapping

Create interactive 3D landscapes where memories and emotions exist as terrain—hills, valleys, and paths that represent your inner world.

EMDR support

Designed to complement EMDR therapy by providing a spatial way to represent and process memory relationships.

End-to-end encryption

Everything is encrypted on your device before syncing. The server never sees your data—only encrypted chunks.

Offline capable

Work without connection. Changes sync when you're ready, storing only the parts you've modified.

Version history

Restore old versions of your maps whenever you need. Every change is preserved and reversible.

Selective sharing

Collaborate or share specific parts of a map. Only people you choose can decrypt what you share.

Important: Alteryn is a tool for personal reflection and therapeutic support. It is not a replacement for professional mental health care or therapy.
