Your thinking has depth.

Filamental projects your files and notes into a navigable, three- dimensional space. Native documents, external assets, and connected media exist as unified nodes within a single conceptual structure.

Every node has a point Every connection gives a reason. The busiest node pushes its neighbours furthest out, and the short runs to dead ends pull in close.
OBJECT PERMANENCE

Two studios, and one structure underneath them

It is two sides of the same coin, two sets of tools, two ways to approach. The Studios use the same data and knowledge, so moving between them is a toggle not a conversion.

Space Studio On the left, the nodes are arranged in their classifications. On the right, the notes, the relationships, structured data, attachments and all the recorded facts sit within the node itself.
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.
Publisher Studio The same space and the same node, laid out to be read. Arrange the graph as a table of contents, allowing your audience to see the relationships. There is a huge amount of customisation available to make your pages your own.
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.
Why this exists

Documents have been linear since the 1980s. The world is a little different now.

01

The flowchart nobody remembers

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

02

The fifty-page proposal

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

03

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.

Nothing here needs a narrator The reasoning is on the connector.
Motion detected, controls, located in... each line says what it is for, so the structure still explains itself to whoever opens it next.
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”.
Premature filing

Every filing system asks where a thing goes before it’s established what exactly the thing is

You have to answer at the beginning, when you know least about it, and the guess becomes a constraint.

Filamental holds the part of a project that has not settled yet, where things sit near each other before anybody decides why. When it does settle there is nothing to convert, because it was files all along.

Why premature filing costs more than untidiness

Ownership

Buy the software and stop renting your work back

01

Your nodes and pages are Markdown on your own disk. Open them in anything, move them anywhere, and keep them forever.

02

There is no account to create and no server holding your work. A service wants to know your business, Filamental couldn’t even if we wanted to.

03

Anything you share is encrypted before it leaves your machine. We cannot read it, with or without the password. 

04

You are not the product. We like money as much as anyone else, we just don’t think selling you and your work is a reasonable way to make it.

File formats
Markdown with YAML frontmatter + any file format imports, attaches, opens
Imports
Obsidian vaults, any wikilink Markdown folder, Mermaid
AI

We don’t do AI. You do.

There is no Filly the Filamental Agent, because it would never be as good as the AI you already pay for. Use or bring that one instead.

The AI you already pay for knows far more about your work than we ever will, and what it has never had is an output that isn’t a document. Connect it to a space and it can hand you a structure instead, which you can pass on as ordinary files that somebody else’s AI will read straight off.

It works the other way round as well. Everything you’ve already built is sitting there as files with the relationships written into them, so there’s nothing to prepare before you point a model at it.

LOCAL MCP

Already works

One click connects Claude Desktop. Claude Code, Cursor, VS Code and LM Studio take one JSON entry, and they read and write the real space rather than a copy of it.

Your own API key

Whichever one you already trust

Paste a key from whoever you already pay and it works out the rest. We supply the connector, not the opinion.

The difference

No metering. No credits. No seats.

Every other product seems to impose AI. We use it quite a lot and don’t see the value of forcing you to use ours, so we don’t.

Connects to
Any Local MCP client, including Claude, Cursor, LM Studio

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

You may have met us already as 3D Filamental Graph, a free plugin that spins your vault around in a tab. That one’s a toy, and we’re fond of it. The part worth knowing is that the vault itself opens in Filamental, as it is, with nothing to import.

Obsidian is open on a second screen here most days, and for knowledge that’s been worked out and written down it’s the best thing we know. Filamental is for the other half, the work that hasn’t settled yet and will eventually have to make sense to somebody who wasn’t there.

One folder runs in both directions, which is the useful part. A vault opens here when you want to see the shape of it and give the links something to say, and a space that’s reached the end of its useful life drops back into a vault, where it goes back to being notes with the structure still in the front matter. It’s the way a photographer moves one picture between two applications, each doing the half it’s good at, and neither of them owning it.

What you get in between is a structure you’ve set yourself. Every type, connector, colour and layout is yours to name and change, and you change them in the app rather than in a config file.

The plugin

A quick look, without leaving

It renders the vault you have open and writes nothing back into it. Every connection in it is a plain line, because a line is all a quick view can honestly show.

The vault

Opens as it is

Point Filamental at the same folder and you can open it as it is, or run Import from Obsidian, which turns those wikilinks into connections you can name, aim and weight.

And back

It goes home as notes

Nothing gets stranded here. A finished space is still plain Markdown with its structure in the front matter, so it drops into a vault and reads like notes again.

Who it is for

Filamental is self-selecting. In 10 minutes you’ll know if it’s for you.

Ciao for now

It isn’t just a whiteboard, or notes app, or doc builder. It’s all of the above.

And it has aliens.

Use it for the work you have, and the organisation happens on the way.
