Fibrae

Saving things is easy. Finishing them isn’t.

Fibrae is a canvas for everything you keep meaning to come back to. Paste it or say it, and it suggests what connects to what, tells you when a cluster has enough in it to become something, and turns it into a first draft you can actually edit.

Never touches a server. Nothing to leak. AI is optional. Outline mode never contacts a model.

How it works

Step one

Paste anything. It lands as a card.

A link, a paragraph, a screenshot from your clipboard. Fibrae works out what it is, pulls the title and preview, and drops it on the canvas.

Step two

It suggests what connects. You decide.

When a card lands, Fibrae shows the few already on the board it might belong with, and why. Nothing is threaded until you say so.

Step three

Threads pull a cluster together.

What belongs together gathers. What doesn’t stays where it is — a canvas is allowed to hold a grocery list next to a year of research.

Step four

It tells you when the cluster is ripe.

Not “78% of your cards are linked” — that’s a mirror. Which group has enough material, enough connection and enough variety to be worth finishing.

Step five

Turn it into a first draft.

A brief, a script outline, a shot list, an argument. Built from that cluster and nothing else — then it’s a normal card you can edit, copy or export.

The two rules

It reads your cluster. Nothing else.

The whole appeal of a draft that came out of your own board is that it actually came out of your own board. So Fibrae holds itself to two rules it doesn’t bend.

  • Only the cluster you picked. Not the rest of the canvas, not your other boards, not anything from outside. If a line in the draft surprises you, you can trace it back to a card you put there.
  • Writing it yourself is a first-class option. Ask for the outline instead and you get the same structure with your sources filed under each heading, and no model involved at all. It’s a real document, not a downgrade — and it is the default setting, not a buried preference.

Where it lives

On your computer, in files you can open.

Fibrae starts saving the moment you type, into your browser’s own storage. No sync, no server, nothing to set up.

Point it at a folder and every canvas becomes a plain .fibrae.json file with your images beside it in attachments/. Back it up, put it in a git repo, keep it in the same folder as your notes. It’s yours, in a format you can read without us.

Inside the app

What it actually looks like.

Real screens, light and dark: the home dashboard, the canvas as cards and as a map, and the small settings underneath.

The small things that make it usable.

Say it instead of typing it

Press the mic, talk, press it again — the words land in the same box you were going to type into. Speech is transcribed by your own browser, so a spoken thought goes nowhere either.

Share straight onto the canvas

Fibrae sits in your phone’s share sheet. Share → Fibrae on anything and it lands on your latest canvas, already unfurled. No app switch, no paste, no second step.

Search that finds it

Ctrl+K from anywhere. Full text across every card, ranked properly, filtered by kind. Enter takes you straight to the card on the canvas.

A nudge, once a week

One line when you open a canvas, about one thing worth returning to. Not a feed, not a badge, not a streak. Dismiss it and it’s gone for the week.

Light and dark, drawn

Both themes designed on purpose rather than inverted, and it follows your system by default. Contrast meets WCAG AA in both.

A phone version that isn’t an afterthought

Most canvas tools hand you the desktop plane shrunk to 6 inches and wish you luck. Fibrae doesn’t: the canvas becomes a readable feed, with the map one tap away when you want to see the shape of it.

Undo that goes back

Fifty steps of history, Ctrl+Z and Ctrl+Shift+Z. Deleting a card is not a decision you have to be sure about.

Export whenever

Every canvas out as one JSON file, any draft out as Markdown. Nothing is trapped, and nothing needs our permission to leave.

Open it and paste something.

Two weeks free and no card to start — one tap to sign in with Google, and that is the whole of it. The first card takes about ten seconds, and you’ll know by the second one whether this is for you.
