You're right — this is a commonplace book, centered on books. Two takes borrowed from journaling & notetaking apps: 5a a warm reading diary (Day One's On-This-Day, gentle streaks, a soft daily prompt, private-by-default), and 5b a tagged notebook (Bear/Craft hashtags & blocks) for wandering ideas across books. Plus Readwise-style quiet resurfacing.
A calm diary of your reading life. Entries by day, a soft prompt, gentle streaks (no guilt), and Day One's On This Day to resurface what you read a year ago. Everything private by default.
Wander ideas across books. Bear-style #hashtags and Craft-style blocks (quote + voice + text in one note). Follow a theme like #memory and see every book where it surfaced — search-forward, no folders.
The captured page becomes real OCR text right away — so highlights and underlines attach to word ranges (casual/wobbly, but exact), and we don't depend on the photo. On top of that: an optional AI layer that surfaces characters, places and terms, and a Commonplace where everything you keep quietly collects itself. Reference by id: 4a–4c.
“I just want to read — until something grabs me.” The page is real text, so a highlight or wobbly underline snaps to exact words. AI is off by default; tap ✦ and it surfaces the characters, places and terms — keep any with one tap.
“I want everything worth keeping in one beautiful place.” What Threads was reaching for, without the tangle. Every quote, person, place and word you save files itself — browsable across your whole library, no organizing.
“I'm lost in a 600-page novel — remind me who everyone is.” A cast that assembles itself from what you've captured, capped at your current page so nothing gets spoiled. Your own notes ride alongside the AI descriptions.
Deliberately divergent — two rooted in the physical book, one familiar reader, two experimental. Shared rules across all: voice is press-and-hold (no stop/save buttons), and text notes live on the page like real marginalia. Reference by id: 3a–3e.
Write in the book. Tap the page to type a note right where your finger lands. Pencil to scribble, highlighter to swipe, and hold the mic to drop a voice pin. Sticky tabs mark the corner.
Real tools, real gestures. Grab the highlighter and swipe it across a line; peel a flag onto the edge; sketch with the pencil. The recorder is an object you press and hold to speak — release to set it down.
Nothing new to learn. The Kindle/Books pattern — select text, pick a highlight color, optionally tap Note. Familiar and fast, but least suited to a photo of a physical page.
Talk, don't tap. Press and hold, speak naturally. It transcribes live and auto-links your thought to the passage you mention — highlighting it on the page. Release to save. No forms, no buttons.
Annotation as a web. The page is a node on a canvas. Pull a thread out of any passage to spin off a quote, voice, or text card — or link it to another book. Later you wander the connections, not a flat list.
“What does that mean — and who was that again?” The itch a physical book can't scratch. Tap any word for a definition, any name for a spoiler-safe who's-this. Borrowed from Kindle's X-Ray & Word Wise; anything you look up can join your Words collection.
The way people actually mark books. A quick !, ?, or ★ scrawled in the margin — one tap, zero typing, anchored to the line. Later, filter your whole library by mark: every “!” you've ever left.
Read the good lines out loud. Highlight a passage and hold to recite it. It saves as audio and transcript, so the quote keeps your voice — replayable in your Commonplace. (Day One audio meets Readwise.)
The page is already saved — this is optional depth. Drag across the page to select & save a quote, tap the ✏︎ draw icon on the image to scribble, and use the two big buttons at the bottom to add a note — speak it or type it. Shown in the 1a Marginalia look; the flow is the same in any concept.
Each concept is the core capture flow — Camera → “reading saved” → Library — as a clickable phone. Tap the shutter, and the app logs your page. Reference a concept by its id (1a, 1b, 1c) in chat.
