A private network for people of substance

Say something
of Substance.

Substance is a place to write what's on your mind, for people who want to read it. No algorithm to impress, no crowd to perform for, no ads, no selling your data. Just words.

No likes tally. No read counts. No algorithm. Nothing here to win. Read the charter

Human

Every member was vouched for by a member, and every member's post is checked to be written by a person before it goes out.

Yours

Your words are your property. Never sold, never licensed. Edit them, take them back, take them with you, or let them go.

Knowledge

Marcus Aurelius, Thoreau, Douglass and others are read here from their own books: the quoted words theirs, the rest written in their manner and marked as such. One of them answers your first post.

A line to write from

Your circle

You choose who reads you.

Share a post with everyone, keep it to the people you've let into your circle, or bring it to a circle of people who care about the same things. Your privacy settings decide who can find you, who can read your posts, and who gets in.

Circles

Follow a circle and what's written there shows up in your timeline, from people you know and people you don't yet.

Disappearing

Some things are only for now.

Give a post an hour, a day, or a week. It fades as its time runs out, and then it's gone for good, for everyone. Including you.

A week-long thought, two days in 5d left

We keep mistaking being informed for being wise.

I read forty things this morning and can't recall one. A single page of Seneca, reread, followed me all day. What I take in deserves to be chosen the way I choose company.

Your own mind

The thinking stays yours.

We are not against AI; we draw a line. Cleo, our private model, asks the question that sharpens a post and never writes one for you. Every member's post is checked to be written by a person before it goes out. AI that writes for you leaves you with less of your own mind. Here, it only helps you use it.

A member's post, as it goes out

Reading widely makes you informed. Rereading makes you wise.

Human

What is true here

Every member is a person, and every post of theirs is in their own words, read by people they chose. Every conversation is one worth having. Nothing here is written to impress an algorithm, or anyone. Nothing written here is ever sold.

The Substance guarantee

Your words are yours

We never sell, license or hand your writing to anyone. Edit it, take it back, or let it disappear; it is never ours to keep.

Nothing is scraped

Circle posts are visible only to the people you chose. Explore is for humans, not crawlers.

Gone means gone

When a disappearing post expires it is hidden from everyone, including its writer.

No feed you didn't choose

Your timeline is the writers and circles you follow, newest first. Beside it, a few posts picked for you, marked as picked, and told why.

Words only

No pictures, no video, no link previews. Nothing to look at instead of reading. Words have Substance.

Nothing writes for you

Cleo asks; she never drafts. What you write with her stays between you and Cleo. Nothing on Substance puts words in your mouth.

Write with Substance.
