Snail: A Manifesto

I

Someone wrote three days ago, and you meant to answer. Then life got in the way. The message slips down the thread, and days run into weeks. You keep thinking, I should write back. It's important. But the longer you wait, the harder it becomes to know how to begin. Eventually, the message isn't just waiting for a reply—it has become a small piece of unfinished business you carry around with you.

So you decide to write back as soon as possible next time. Problem solved.

Except that it isn't. You've only passed the problem on. Now the other person has a message waiting for them. They may reply immediately, putting you back on the clock. Or they may fall into the same trap you just escaped: meaning to answer, putting it off, watching the message sink down the thread, and carrying the same unfinished business with them.

So perhaps you try email instead. But email is still, for just about all practical purposes, immediate. Your message lands somewhere in the never-ending stream of messages we all receive, and the same question remains: When should I answer?

And the trouble is that the guilt you feel is not entirely misplaced. In a medium where anyone may write at any time, silence carries meaning: it can look like you had a moment and chose not to answer. Your friend is not wrong to read it that way. There is simply no other arrangement between you that would let the silence mean something else.

That is the real problem, and it is not one you can solve by replying faster. You solve it with an agreement. Tell someone you will write in a month, on a day you have both fixed in advance, and your silence in the meantime stops being meaningful. It becomes the shape of the thing you agreed to. They will be glad to hear from you next month, precisely because they knew next month was when you were coming.

But agreements like that are hard to keep. The allure of just clicking send, once you wrote the message, is just too strong. Draft folders become messy. Life intervenes. We need a tool that can hold the rhythm for us.

Snail is an async, turn-based correspondence protocol.

You don't decide when the letter is published. Fixing the publication slot and rotating the writer turns a private obligation into a shared contract—both of you know when the letter is coming, so the wait is no longer something either of you is doing to the other. You still owe a letter; you simply owe it to a day rather than to a person you are keeping waiting. You write when you can, or when you feel like it; it is published only when your publishing date and time arrives.

It is a postman. It doesn't keep the words you wrote, the pictures you sent. There is no letters table. We hold the date your letter is due and the number that points to it, and when the hour comes we hand it on. If you have asked for letters by email, your message is passed to the mail service on its way out. That's it.

A snail group is a shared space that belongs to its members. It requires a small amount of care to keep the lights on and the rotation spinning. It is free, and we expect it to stay that way. That follows from the pillar above: because we keep none of your words, a correspondence costs us almost nothing to carry, and there is no mounting bill to pass on to you. If we ever charge, it will be for extending what snail can do, never for taking away something that already belongs to you.

Nor could we ever charge you for your own past. The letters you have already exchanged sit in your group's chat history, which is yours—not a library we could lock. Walk away from snail entirely and every letter you have received is still exactly where it was; only the rotation stops.

By default, a letter arrives every other week, whatever the size of the group. What changes with size is how often it falls to you. Writing with one other person, you write about once a month. In a quartet, every other month. Among a dozen, twice a year—and in between you are simply a reader, which is most of what belonging to a correspondence consists of.

Grow the correspondence and you read more and write less. The rhythm follows the size of the group itself, and from there you can stretch it—or quicken it—to whatever pace your particular set of people can actually keep. Fast enough that the connection doesn't cool, slow enough that you have something worth saying. If the turns keep arriving before you are ready for them, the answer is a slower cadence.

IV

A system that punishes a missed turn has reinvented the thing we are trying to escape.

Between two people, a missed turn carries no penalty: no strike, no mark against you, nothing that accumulates. The rhythm moves to the other person and comes back around to you, and if you miss that one too it comes back again, for as long as it takes. Your friend will see that your turn came and went without a letter—we say so plainly rather than covering for you—but that is the whole of it. Nothing else happens, and nothing is counted. Write next month. Write next season.

In a group it has to cost a little more, because other people are standing behind you and the rhythm is theirs too. Your slot passes to the next writer and the letters keep arriving on time; a correspondence of six should not always wait for the one person who never writes. Go quiet for several turns running and you are automatically excluded from the group, so the circle keeps turning for everyone else. Anyone can invite you back at any time.

A correspondence that only exists inside one company's app is a correspondence held on loan. The company is acquired, or loses interest, or decides your years of letters are now a premium feature—and the archive that was supposed to be the point turns out to have been collateral all along. We did not want to be that, and good intentions are not a safeguard. So we built so that we could not become it.

The rule we set ourselves: your letters live somewhere we do not control. Not encrypted on our servers, not exportable on request—simply not ours. If snail disappeared tonight, every letter you have sent or received would still be sitting where it is tomorrow morning, and no one currently in the group would need our permission to read it. Correspondence you can keep without us is worth more than correspondence we guard for you.

The same rule shaped where your draft lives. It is nothing more than a private chat, on infrastructure that already exists—which spares us from building a draft store, and spares you from trusting us with one. You write in snail's own app, a quiet place made for composing a letter; what you type is kept in that private chat rather than in a database of ours.

It also settles a question every tool like this has to answer: where should the letter arrive? A destination of its own would be tidier, and would be visited on the first week and forgotten by the third. Letters should arrive where you already are.

Today that ground is Telegram, with the honest trade-off that its terms, its outages, and its future are outside our hands. It is where the protocol currently lives, and it could live somewhere else.

VI

Snail doesn't have a send button. It doesn't have streaks, badges, or reminders that you are falling behind. No algorithm choosing what you see or when. No ads, and no one to sell you to. No letters on our servers.

No count of things you have not done. A letter that has arrived and not yet been opened may well be marked as such—that is one letter, this week, and knowing it is waiting is the right call. What you will never find is a number that accumulates: nine, then twelve, then forty, a growing measure of how far behind you have fallen. We won't keep score.

No audience while you write. You compose in the web app, which no one else can see into. Nobody learns that you began a letter on Tuesday and abandoned it, or that you have been at it for an hour, or that you rewrote the first line eleven times. Your attention is never reported back to anyone; whether the writing came easily is yours to disclose, or not.

Each of those is something we could build in an afternoon. Each of them would make snail worse in exactly the way we are trying to avoid.

VII

The world does not need another way to talk faster. It needs a way to talk, and keep talking, better.

This is for the four friends who haven't caught up in a year. For the family spread across three time zones. For the people who are tired of "pings" and ready to get back to "letters," even if they have never actually received one.
