Until Folio, the proof you wrote a piece came after.
With Folio, the proof is the writing.
InkFolio — Web · Coming soon
Words on a page. And the proof you put them there.
For two hundred years, the world assumed words on a page were written by the named author. That assumption is gone. Folio is the first writing surface built for what comes after.
InkFolio
/ˈiŋk-foʊ-lioʊ/
noun.
A writing surface for serious writers, with the proof of authorship anchored into the act of writing.
The shift
Authorship, in 2026, is no longer assumed. The proof has to be the writing.
For two centuries, a writer proved authorship in one of three ways. They remembered writing it. A colleague remembered. They could find the drafts.
It was rarely enough. It is no longer enough at all.
In 2022, software learned to produce essays, articles, novels, and screenplays that pass as the work of a writer. Not always well. But well enough that the question — did you write this? — stopped having a reliable answer. Editors ask it. Readers ask it. Lawyers ask it. Working writers answer it to their own publishers, on demand.
The default of trust is gone. The burden of proof has moved.
The argument · six acts
Folio captures the editorial process — the pauses, the revisions, the dead ends — at the moment it happens, invisibly, underneath the page.
When you publish, the proof appears as its own surface: cryptographically anchored, independently timestamped, verifiable without your permission and without anyone's platform.
- You do not have to remember writing it.
- You do not have to find the drafts.
- You do not have to defend the byline.
You already wrote it.
The proof was being written alongside it.
This is what authorship looks like in the age of AI.
A writing surface — with proof of authorship built into the page.Nothing else writes like this. Nothing else can.
The writing surface
Calm where the writing happens. The proof, when it leaves.
The verification is the reason to use Folio. The writing surface is the reason you'll want to.
01 · The page
A drafting surface that gets out of the way.
Considered type on a clean page, in the lineage of iA Writer and the school of typography-as-respect. The drafting surface is the work — no badges, no indicators, no compliance prompts. During the act of writing, you are in a writing tool. Not a verification tool.

02 · The credential
The proof appears at publish. Beautiful. On its own page.
Only at the moment of publish or export does the verification surface appear — a cryptographically anchored credential any reader, editor, or lawyer can resolve without leaving your post. Not a step in the workflow. A reward at the end of it.

The experience
Built for the hour before sunrise.
Folio is built for prolonged time on the page. The typography is publication-grade. The cursor is patient. The chrome stays out of the way until you ask for it.
-
Focus on the sentence
Surrounding paragraphs fade. The sentence you are writing stays at full contrast.
-
Considered typography
Optical sizing, generous line height, real italics. Set like a serious page, not a draft.
-
A cursor with weight
A patient sage caret. Selection states tuned for long reading and long re-reading.
-
No assistant. Ever.
No suggestions. No autocomplete. No co-author. The page is yours, the sentence is yours, the work is yours.
The modes
Six surfaces. One protocol. Different posture per medium.
Folio's writing surface shapes itself to the medium without constraining it. Same editor. Same calm. Same protocol underneath. Each mode adds the structure that medium requires — and nothing it doesn't.
Freeform
The cursor sat patient. I let it sit.
A page. A sentence. Nothing else. For the moment you do not know what kind of writing it is yet, only that it needs to be written.
Essay
The argument depends on a single distinction: was it written, or was it generated?
For arguments long enough to require structure. Section discipline, citation affordances, word-count goals, publish-ready preview.
Newsletter
Friends — three small things this week, and one larger thing I am still thinking about.
For writing that goes out on a cadence. Title, subtitle, lead, body, callout, sign-off — in a surface that respects the prose more than the publish button.
Short-form
A post is a sentence. Maybe two. The rest is the rhythm of the line break.
For the post, the thread, the essay that has to land in two hundred words. Length discipline, hook-and-payoff hinting, draft-and-iterate flow.
Screenplay
Int. Study — NightThe writer stares at the page. The page stares back.
Industry-standard format without Final Draft's chrome. Sluglines, action, character, dialogue. Beat-sheet awareness when you want it; off when you don't.
Story
Chapter three. The boat had not yet come, but the lights on the harbor had begun to change.
For long-form fiction. Scene and chapter structure. Character tracking. The structural awareness of Scrivener, in a surface that does not look like 2004.
For whom
The writers who can no longer assume the question won't be asked.
Working journalists
Did you write this? is the question your editor will ask next year. The question every reader is starting to ask. Folio's record is the answer, on demand, before either of them ask twice.
Essayists and Substack writers
The byline is yours. The proof of the byline has not been, until now. Every essay you publish through Folio ships with its own verification record — a reader can open it without leaving the post.
Novelists
For the work-for-hire dispute. The ghostwriting accusation. The contract clause about provable authorship that no novelist has been able to honor — until the protocol existed to honor it with.
Screenwriters
For credit disputes. WGA arbitrations. AI-attribution accusations. And for the personal record that the script was yours, scene by scene, draft by draft, year by year.
Newsletter writers
For the subscriber who needs to know they're reading you. For the platform you publish on that doesn't yet ask, but will.
Long-form storytellers
For the memoir, the novel, the script-that-wants-to-be-a-novel. The work that took you three years is recorded as the work that took you three years. The proof is anchored to every session.
Publishing
The moment of finishing.

When
Pilot in summer 2026. Public beta after.
Folio is in private development. A small cohort of writers, editors, and publishers is testing the drafting surface and the publish flow now. Public beta follows iOS InkWave's launch.
