Nobody pays to think in Filamental

You pay when handing things over becomes the job, rather than something you do once. The canvas, the physics, the AI, as many spaces as you like and your first live share link are all free, and stay free.

Personal

Free

Permanently. No account, no card

As many spaces as you want, linked across your machine

Discrete structures joined at the edges, rather than one vault that never stops growing. Plenty of people prefer working this way.

  • Unlimited spaces, with unlimited Bridges between them. Bridges never count against anything.
  • The whole of Space Studio: the 3D/2D canvas and physics, Dark Energy and Layers, your own node and connector types, the Lens sidebar, the Connect tool.
  • Everything AI. The built-in MCP server, the skill files, one-click graph export, and the bring-your-own-model companion. Nothing metered.
  • Import, Templates and export, including an image of the canvas as it stands.
  • Up to 20 nodes in each space, roughly one finished document.
  • Publisher Studio itself. Page layouts, cover images, long-form formatting, subpages and theming. Take it as far as you want and make it something you are pleased with. Not a preview of it.
  • One live share link. Send something to someone without paying us. Remove it and the next one is free too, on a new address.

Download and use it forever without paying us anything.

Everything, without the ceilings

For when one document at a time stops being enough, and one space stops being big enough. Nothing new to learn, the same app with the lids off.

  • As many live share links as you want. A proposal with each client, every one of them current, none of them waiting on you to remove another.
  • Push a new version to the same address. The link you already sent keeps working and shows the current work, so nobody has to be sent a second one.
  • The whole thing as a single HTML file. No link to manage and nothing to expire, because there is no server in the picture. It opens in any browser at the other end.
  • Presentation mode. Fill the screen with the structure and turn it slowly, for when you are in the room rather than sending a link.
  • Unlimited nodes in every space.
  • Your own background images and video on the canvas.
  • Links stay encrypted on your machine before they reach us, so we cannot read them either. That is true on both plans.
  • Licensed for commercial use.
  • One tier. Nothing above it, no seats to count, and nothing else to buy.
How you would like to pay

Card, Apple Pay and Google Pay. Tax is added at checkout where it applies. Your license key arrives by email, and goes into Settings then Account.

Full refund within 30 days, no questions asked. VAT or sales tax is added at checkout where it applies, and is collected by Creem, our Merchant of Record.

The first 15 days

Every install starts on Professional

You get the whole thing for fifteen days (Publisher Studio, sharing, all of it) without paying and without making an account. There is no card to enter and nothing to cancel.

When the fifteen days end, nothing switches off. The install moves to the Personal plan and stays there permanently. Your files are untouched, your spaces still open, and everything on the free side of this page keeps working. You are not on a countdown to a paywall.

At that point we ask for a first name and an email address. We treat our users as adults, and ask that in exchange for free software, you allow us the opportunity to make the case for the paid version once or twice a year. That is all it is for.

You can skip it and it may ask again later. It doesn't create an account, it doesn't gate the app, and it does not block a single Personal-plan feature whether you answer it or not.

One thing worth knowing if you publish during the fifteen days: a link you created keeps working for its full 180 days afterwards. You lose the ability to push a new version to it, and you keep the ability to revoke it.

Where the line is

Free to think and work. You pay to show it to somebody

Nobody pays to think. Everything that builds, arranges or reasons about the work is free and stays free: the whole of Space Studio, the whole of Publisher Studio, all of the AI, and as many spaces as you care to keep. You can take a structure as far as it will go, lay it out, theme it and make it something you are pleased with, without ever paying us. Nothing on the free plan is a demonstration of something better.

Twenty nodes in a space is about twenty pages or sections, which in practice is a finished proposal, a knowledge pack or a reference document rather than a fragment of one. If you need more room, you make another space and bridge to it. That costs nothing, and it is how the free plan is meant to be used.

What you pay for is the moment it leaves your hands. A second live link, because the first one is still doing its job. A new version pushed to an address somebody already has, rather than asking them to use a different one. The whole document as a single file you can attach to an email. The screen filled with it while you stand next to it. A space that will not sit inside twenty nodes. That is the shape of somebody doing this for a living, which is who it is for.

The free plan still keeps one way out, because sending somebody one finished thing should not need a card. Publish a live link, send it, and take it down again when it has done its job. The next one is free too.

Start anywhere

The download is the same file either way
