Your thinking has depth.

Draw a connection and watch everything find its place.

Filamental turns your files and notes into a space you can walk through. Every page has its place, and every connection says why it’s there.

Object permanence

Think it through.
Then hand it over.

Two studios share the same pages, so moving from one to the other is a click.

Space Studio. A residential development space with its node pages listed down the left, grouped by counterparty, development, issue, milestone, obligation and person. Ash Tree Lane is selected in the graph and its panel on the right carries the notes, the relationships out to the main contractor, developer, planning permission and architects, and its recorded properties: eight semi-detached houses, a gross development value of £3.2M and a pre-commencement phase. — Space Studio Where the work builds up. Every page has a place, and every connection has a name.

Publisher, on the same space. The graph stays on the left with Ash Tree Lane joined to its main contractor, its architects, its ecologist and the Start on Site milestone; on the right the same development is a laid out document, with a photograph of a new-build street as its cover, the Ash Tree Lane heading and body copy giving eight semi-detached houses on a 0.4 hectare infill site under planning reference 2024/0891/FUL. — Publisher Studio The same pages, laid out to be read. Send it as a link, download it, or present it in the room.

Space Studio See how a space works Connections that say what they mean, and a whole document behind every node. Publisher Studio See how publishing works A link, a single file, or the screen in the room.

Why this exists

Documents have been linear since the 1980s.

The flowchart nobody remembers

It made sense in the meeting. By Thursday it’s boxes without a narrator.

The fifty-page proposal

Everything is in there somewhere. Do I scroll up or down?

The folder that became an archive

You didn’t lose the work. You lost sight and control of it.

It isn’t you. The tools flattened the problem before you ever got to it.

A Filamental space mapping smart home devices. Named nodes are joined by colour-coded connectors (green for controls, orange for triggers, red for location) with the relationship written on the arrow itself, such as “motion detected”. — Nothing here needs a narrator The reasoning is written on the connector.

Premature filing

Know what it is before you decide where it goes.

Filamental holds the work that hasn’t settled yet. When it does settle, there’s nothing to convert, because it was files all along.

Premature filing Why premature filing costs more than untidiness You file it on the day you understand it least.

Ownership

Your work stays yours.

We sell software, and that’s the whole business. What you make in it is yours to open, move and keep, with or without us.

Your files: Markdown; On your own disk, and they open in anything.
What you share: Encrypted; Before it leaves your machine. We can’t read it either.
Accounts: None needed; On either plan. Download it and start.

There’s nothing artificial about your intelligence

There’s no Filly the Filamental Agent, because she’d never be as good as the AI you already pay for. Bring that one instead.

Your AI already knows your work far better than we ever will. Connect it to a space and it can hand you a structure instead of another document.

Claude Desktop: One click; Claude Code, Cursor, VS Code and LM Studio take one short setup step.
Your own key: Paste it in; From whichever provider you already pay.
From us: No meter; No credits and no seats. Your AI, on your bill.

AI How Filamental works with AI Five routes, and the model you already trust. Connections Everything Filamental connects to The assistant you already pay for builds inside your space.

Obsidian

If you already keep a vault, you’ve done the hard part.

Your vault opens in Filamental as it is, and a space that’s done its job goes back as notes. One folder, both directions.

You may know us already from 3D Filamental Graph, our free plugin for a quick look without leaving Obsidian.

Obsidian Filamental and Obsidian The free plugin, and one folder that works in both.
