You were about
to send it.
Write it here instead. Something kind comes back, and it never reaches them. unsend is the inbox for everything you can't send.
the five doors
Everyone has one unsent message.
Most of us have five.
Pick who it's for. The room changes with the door: the words it sends back, the colour of the light, what it never asks of you.
how it works · 90 seconds
write it exactly how you'd send it
The 2am version. The angry version. The one you've rewritten four times. It goes in the inbox, not to them.
get back what you needed to hear
Something kind and honest comes back in seconds. Not therapy-speak. The reply the situation actually deserved.
then keep it, or burn it
Keep it and it joins your vault, the private story of what you never said. Burn it and you watch it dissolve into embers, gone for good.
keep it
the vault remembers
Kept messages land in a dated, private timeline: the story of what you never said. It lives on your device and nowhere else.
burn it
the embers don't
Watch the words dissolve into embers and disappear for good. Some messages just need a witness, not a recipient.
before you trust it with the real thing
not therapy
and it never pretends to be
unsend is a self-guided writing practice with a panic button, not treatment or crisis care. It says so on every page, and the crisis line is never behind the paywall.
an old tool, a new address
the unsent letter works
Therapists have assigned unsent letters and expressive writing for decades: say it fully, just not to them. unsend gives that practice the shape the urge actually takes, a message thread at 2am.
