Hylest is an innovative app that lets you create digital heirs.
Your messages, memories, codes, or wishes are automatically and securely delivered, on the day you are no longer here.
Preparing a Hylest capsule is not about thinking of the end — it’s about offering continuity, avoiding silence, and enriching the lives of those who remain.
Because without realizing it, we all leave traces (memories, codes, thoughts, or explanations) that too often end up lost or ignored.
Hylest allows you to pass on what truly matters.
Four steps to protect what matters most.
No technical skills required.
Create a capsule
Think of someone who matters. Create a capsule in their name in just a few clicks.
Add what you want to pass on
Insert your messages, videos, photos, documents, and personal codes.
Link your capsule to its recipient
Associate the capsule with your heir’s Hylest account. It will be visible in their application, but its content will remain locked.
Hylest takes care of the rest
Once our life has come to an end, the capsule will open automatically under certain conditions, or manually with the help of a trusted person.
Secure and personal spaces to preserve what truly matters
A capsule is a digital vault dedicated to a person of your choice. Partner, children, family, friends…
Each capsule is individual, and only the designated person can access it through their own Hylest app.
Even if a capsule is linked to someone, it remains fully editable at any time.
They are words we want to pass on, and would never want to see disappear.
And sometimes, they are things we are not yet ready to say.
But that we wish to entrust, one day, when the time is right.
Features designed to preserve and pass on your digital legacy with simplicity.
