Colophon

Private read-later for articles, feeds, PDFs and EPUBs, with highlights, read-aloud and on-device AI. Pro adds Pencil notes, Instapaper import and Obsidian export.

Colophon is a private read-later app for people who want to keep articles, feeds, PDFs and EPUBs in one calm library.

Save pages from Safari or any app, subscribe to RSS feeds, import books and PDFs, then read with clean typography, progress tracking and device-wide search. Colophon keeps your highlights, margin notes, handwritten ink and reading history attached to the piece you saved.

Built for focused reading:

• Save URLs, RSS/Atom feeds, EPUBs, PDFs and local HTML
• Import Instapaper CSV or HTML exports with Colophon Pro
• Read in an adaptive iPhone and iPad interface
• Highlight passages, add margin notes and search your saved library
• Draw with Apple Pencil on articles, books and PDFs
• Resume visual reading or read-aloud listening where you left off
• Review saved highlights and handwritten notes over time
• Use widgets for quick access to your reading
• Export rich Markdown to an Obsidian vault
• Sync supported data with iCloud when enabled
• Connect an optional Miniflux account for two-way feed sync

Private by design:

• No tracking
• No account required
• No collected data in the app privacy manifest
• On-device AI features, when available, run on your device for summaries, key points, tags and article Q&A

Colophon is designed as a quiet desk for serious reading: capture what matters, mark it up, and let your library become searchable knowledge.
