Draft your one post.
In the planned sign-up, you'd create a capsule while you're alive. You could edit your draft until you choose to seal it.
One post, written while you're here and kept private. It would only be released after your death has been reliably confirmed.
We leave traces of ourselves everywhere. OnePostLeft imagines something more intentional: one post you write in your own time, for a time when you can no longer say it yourself.
A post like this calls for care. Before any real message could be released, death verification and safeguards would need to be reliable.
In the planned sign-up, you'd create a capsule while you're alive. You could edit your draft until you choose to seal it.
After sealing, your one post is meant to stay private and not be edited or replaced. Details around withdrawal still need to be decided.
A future release would need reliable verification and safeguards. A missed check-in alone would never be enough.
The vision is to open a central public feed after one million capsules have been sealed. This is a proposed milestone, not a live count or a confirmed participation limit.
A future sharing card could show that someone chose to leave one post. It should never reveal the private post itself. What a public profile or card can show still needs careful decisions.
