For iPad, iPhone & Apple Pencil
Colophon turns the articles, books, and PDFs you mean to get to into calm, well-set pages, annotated in your own hand and remembered by an intelligence that never leaves the device.
Coming soon to the App Store · Free to read · No account, no tracking
Recorded straight from the app: highlights and Apple Pencil marks, in four colours. (Sped up.)
Saved from any app, stripped to the words, filed and indexed before you sit down.
EPUBs on a properly paginated page, with your place always kept.
Papers and scans alike. OCR makes even a photographed page searchable.
The library
Inbox, folders, feeds, and collections. Every article arrives already extracted, filed, and indexed to the word. Feeds sync themselves, both ways, through your own Miniflux server if you run one.
At the bottom of the shelf: a reading streak and a words-read count that mind their own business.
The margins
Select a passage and the color bar rises. Highlights anchor to the words themselves, so they survive reflow, resizing, and export. Tap a mark to recolor or remove it. Highlighting is free.
Write straight into the margins with Apple Pencil — or with a fingertip on iPhone, where there is no Pencil to reach for. Your ink follows the text and becomes searchable, like everything else. Pro
Or leave yourself a comment: a private note threaded onto a passage, for the argument you want to have with the author later.
The intelligence
An abstract of every article. Key points, suggested tags, and answers drawn from your whole library, with citations back to the page. All of it written on the device, by Apple Intelligence.
There is no cloud model, no account, and no server. Nothing you read is sent anywhere to make that work.
The direction
خواندن به فارسی، همانطور که باید.
Farsi and Arabic articles are detected on arrival and set the way they should be: correct direction, correct typography, mirrored controls. Not translated interface strings bolted onto a left-to-right page; a reader that genuinely reads both ways.
After dark
A true night setting, ink on slate rather than white on black, for the hour when the house has gone quiet.
The capture
Share from Safari, or any app, and it’s on the shelf by the time you sit down: extracted, filed, indexed, and summarized. Drop in an EPUB, a PDF, or a saved HTML page and it’s simply there.
Coming from somewhere else? Colophon Pro brings your Instapaper export with you, so the years you’ve already spent saving things arrive intact.
And the rest
Everything below ships in the same quiet app, built for readers rather than a feed. A few of them ask for Colophon Pro; most don’t.
The terms
Colophon is free to read with. The parts that plug into the rest of your life — ink, sync, export — are Colophon Pro: a single payment, no subscription, no renewal to dread.
The whole reading room.
One purchase. No subscription.
Bought once, on every device you own. Nothing expires, and nothing you have already made is ever taken back from you.
Privacy
Colophon is in the final stretch before release. Leave your address and you’ll get one email, the day it ships.
For iPhone and iPad, on iOS 26 and later.
