The numbers nobody tracks
Passive Perception, Investigation and Insight for all your players, on one screen, without a click. Plus who's concentrating, who's raging, and who took a level of exhaustion two hours ago.
◆ DM-only by default
Everything you can't say out loud, in one place.
Your party's sheets live in a character-sheet app. Your maps live in a virtual tabletop. The secrets, the debts and the thread nobody has pulled yet live in your head — and you lose one every session. DM's Familiar is the private screen that holds them.

The Players tab, exploring. Which stats get a well is configurable per campaign; violet is always DM-only.
What it does
Three things every DM forgets, held where you can see them
The secrets you're carrying
Which patron is lying to whom. Whose backstory is about to collide with the plot. Attach a private note to any player, NPC or thread — marked violet, collapsed by default, never shown to anyone.
What actually happened
Press N from anywhere, type the thing you'll otherwise forget, press return. No fields, no categories. Clean it into a recap next week, or never.
The five tabs
Five destinations, fixed order, bound to your left hand
Nothing reorders itself, so muscle memory does the navigating. You never mouse to change tabs mid-sentence — and ⌘1–5 keep working while you are mid-note.
Players⌘1
Choose which stats get a full well and which sit on the compact row — per campaign, and separately for exploring and encounters. Flip to encounter mode and the wells grow; cards never move.
Session⌘2
Tonight's log, timestamped and append-only, with your plan for the night beside it. Sessions start and end explicitly, and the numbering can begin wherever your campaign already is.
NPCs⌘3
Searchable roster with relationships and status. Plus four throwaway names on tap, for when they talk to the fishmonger.
Campaign⌘4
Where they are, what day it is in-world, and every thread still hanging — one line each, with the session it surfaced in.
Reference⌘5
Conditions, DCs, action economy, cover and light — all of it on one screen, so you stop opening a sixth browser tab.
What it won't do
No HP. No initiative. No dice. On purpose.
Your character-sheet app already tracks hit points, and it tracks them better than a second app ever will — because it's the one your players are typing into. A dashboard that mirrors that data is a dashboard that's wrong by round three.
So DM's Familiar holds nothing that decays without you. Every number on screen is either static reference or something only you know. That's why it can stay open during combat instead of competing with the tracker.
No hit pointsNo initiative orderNo dice rollerNo player logins
Where it sits
Character sheetsSheets, hit points, the encounter tracker. Deep-linked from every player card.
Virtual tabletopThe map and the tokens. Every location links straight to its scene.
DM's FamiliarEverything neither of them holds: passives at a glance, temporary effects, your secrets, and tonight's log.
One DM, one campaign, one browser tab. There is no player-facing view to mis-click, because there is no player-facing view.
Your next session starts in a few days. Set it up in ten minutes.
Enter your party's names, write down the three things you're currently keeping in your head, and close the tab until Friday.
