Everything LesterMark does

LesterMark bookmarks the thing itself — wherever it actually lives — so you can find it, search it, and open it straight back to its source. No copying, no moving files, no separate folder structure.

Mac — Capturing

⌃⌘C captures whatever is frontmost.

LesterMark detects the active app and captures the right thing from it — no choosing, no dialog. 20+ source types supported:

⌃⌘S — Capture & Save saves a permanent copy of the content alongside the bookmark — the full webpage, file, or note text — into iCloud. Useful when you need the content visible to other Shared Space members who may not have access to the original, or to make a Mac-only object (like a local file) viewable on iPhone and iPad.

Shared Spaces & Chat

Collaborate in real time. Talk while you work.

Create a Shared Space and invite others with a simple link. Everyone in the Space sees the same bookmarks, can capture into it, and stays in sync over iCloud — changes arrive within seconds on every device.

Every Shared Space has its own Chat thread: a live, iMessage-style conversation between all members. Messages are stored as bookmarks in the Space’s own CloudKit storage — they sync with the same reliability and speed as everything else.

💬

Chat thread

Per-Space conversation visible to all members. Send messages, react, follow along — without leaving LesterMark.

🔔

Push notifications

New messages arrive as banner notifications when you’re not in the app — on Mac (System Notifications) and iPhone/iPad.

✓✓

Read receipts

“Seen by…” shows who has read each message. Read position updates automatically when you open Chat.

⚡

Instant sync

Captures and messages appear on all devices within seconds. No polling, no refresh button.

🔢

Unread badge

A red badge on the chat icon counts unread messages. Clears automatically when you open Chat.

Relations & Links

Connect any two bookmarks with a typed relation.

Paste Link (⌃⌘V) inserts a lestermark:// link into your current note and records the relation between the two bookmarks simultaneously. Show Relations (⌃⌘R) shows all in-links and out-links for the active note in a floating panel.

Relation types: Reference, Supports, Contradicts, Part of, Mentions — and more. Relations are searchable and browsable.
