Notes that stay connected to what they mean.

Quick capture when you need it. Rich context when it matters. prismNotebook remembers the person, event, or task a thought belongs to — so you can find it again without rebuilding the room it came from.

01  ·  Why

Most notes apps are filing cabinets. This one is a working memory.

You shouldn't have to remember where you put a thought in order to get value from having written it. prismNotebook keeps context close, surfacing the right note when the right person, meeting, or task is in front of you.

01
Context matters
A note linked to a person, event, or task is worth ten loose ones. Link lightly, find fast.
02
Capture fast, organize lightly
No heavy foldering, no rigid notebooks. Write the thought; structure catches up later.
03
Private by default
On-device first. Sync is conservative and explicit. No analytics, no trackers, no data brokers.
04
Standalone first
Valuable on its own. Better inside the Prism suite. Never dependent on the rest to earn a place on your home screen.
02  ·  How it feels

Four moments that make up a day of notes.

01
Capture
Launch fast. Write a thought, a quote, a to-read, a reminder. No dialog asking what kind of note it is.
02
Link (optional)
When it matters, attach the note to a person, event, or task — via a light reference that holds up across the suite.
03
Return
Open a contact, a meeting, or a task and prismNotebook surfaces what you already wrote that belongs there.
04
Keep
Notes are yours. Export any time. Nothing is held hostage by a subscription or a cloud you don't control.
03  ·  The Prism suite

Four focused apps. One shared context layer.

prismNotebook talks to its siblings through stable suite references — a person, an event, a task — never by duplicating your data. Each app stays standalone, but together they become a working memory that outlasts any single view.

prismContact
Relationships you actually maintain. Prompts when someone deserves a check-in.
prismcontact.app →
prismTask
Follow-through without guilt. Turn a note into an action in one tap.
prismtask.net →
prismCal
A calendar that has your back. Meeting notes continue where prep left off.
prismcal.app →
LaClair Technologies
The studio behind it all. Independent, privacy-first, built to last.
laclairtech.com →

Shared app group group.com.laclairtech.prism.shared and iCloud container iCloud.com.laclairtech.prism.shared carry references only — your note bodies stay with prismNotebook.

04  ·  Privacy, plainly

Your notes live on your device. Full stop.

Sync uses Apple's iCloud with your account — we never see it. No analytics, no advertising SDKs, no silent background exports. If that changes, we'll tell you before it ships.
