About Letheca
Letheca is an anonymous, ephemeral message board built around a single idea: speech without a permanent identity attached to it.
No accounts. No usernames. No followers. No profile pages. No persistent social graph to perform for. Every post lives for exactly 24 hours and then disappears.
The modern web is excellent at preserving everything forever. Letheca intentionally does the opposite by making forgetting the default and permanence the rare exception.
Where does the name come from?
The name is inspired by Lethe, the river of forgetfulness in Greek mythology. Souls who drank from Lethe forgot what came before.
Letheca follows that spirit: most messages fade out, context dissolves, and identity does not stick. What remains is presence in the moment, not a permanent personal record.
Ghost Traces
There is one deliberate exception. If a post gathers enough anonymous "echoes" before expiring, it earns a Ghost Trace: a single permanent sentence preserved in the public record.
No account is attached. No conversation thread is preserved. Just evidence that, for a brief moment, something resonated strongly enough to outlive the current.
