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.
Where the work accumulates. Each node is a page of your writing, placed in space and joined to the others by connections you name, so the reasoning stays in the pages and how it all fits stays in the structure around them.
Somewhere to keep thinking, rather than somewhere to file things and forget them. Leave it for a year and you can still see the shape of what you know.
Where you curate what goes out. The same pages, laid out to be read: covers, columns, images, and the arrangement itself as the contents page. You can build entire documents here without ever touching the Space Studio, and plenty of people do exactly that.
Shareable as a link or a downloaded HTML file. Nothing to install at the other end, no account to make, it simply opens in a browser.
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.
It made sense in the meeting. By Thursday it is boxes without a narrator.
Everything is in there somewhere. Do I scroll up or down?
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.
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.
Your nodes and pages are Markdown on your own disk. Open them in anything, move them anywhere, and keep them forever.
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.
Anything you share is encrypted before it leaves your machine. We cannot read it, with or without the password.
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.
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.
If you work in Claude Desktop, Claude Code or Cursor, just plug them in and it is there the moment you open them.
Cloud or local, whichever you already trust. We supply the connector, not the opinion.
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.
Our sector pages, each written using an example of the kind of work you do, attempt to illustrate the integration of the tools you already have open and the problems you already have.
