The same canvas works whether you're gaming in person or online. Set it up once.
In person
Cast the battle map to the room TV and run the encounter from your own screen. Your players see exactly the dungeon you're ready for them to see, nothing more.
Pin your PDFs, ambient tracks, stat blocks, and random tables to the canvas during prep. Come game night, everything is exactly where you left it. Open Overseer, skip the setup, and start the session.
Stack your monster blocks, spell cards, and rulebook pages into a single tabbed tile. One click mid-combat and you're on exactly the page you need, right where you left it. Your players don't see you search.
Online
Whatever you already use to run your games opens as a tile on the canvas. It sits right beside your notes, ready when the party does something you weren't expecting.
Set a hotkey for every screen before the session starts. Mid-narration, when the party finally opens that door, you're already on the encounter map before you finish the sentence.
When it's time for the reveal, pull the map into its own window and share it to the call. Your players see exactly what you put in front of them. Everything else stays on your canvas.
One window for everything you bring to the table. Drop in a PDF. Embed Roll20. Pin a playlist. Resize, shortcut, and rearrange your screen. Everything in one place for frictionless sessions.

The tool you didn't know your your table was missing
I've been in the app for less than 5 minutes and can already see how much time and window juggling Overseer's going to save me!

I've been testing for 15 minutes and I'm already in love.

I have nothing bad to say about Overseer Studio. It's been nothing but amazing — and I know it'll only get better from here.

Oh yeah, I think I'm gonna like this. Efficient, everything's in one place. Excited to show my players.

Really impressed with the studio so far, haven't managed to break anything on accident yet!

even when i'm not GMing i've gotten a lot of use out of using overseer to keep track of my personal notes for campaigns i'm playing in! it's super easy to jot down notes on details and worldbuilding, and it's exciting to pull out details my GM laid out ages ago and didn't expect anyone to remember.

My setup would break all the time, and I’d rebuild before most sessions. Now…I set it up once, I don’t have to fuss with it, and everything is there when I return. I’ve barely scratched the surface of what the app can do, and it’s already made a huge difference in my time and sanity!

My comment has to be about overseers dev, gave some feedback regarding plugin development and they not only took them all into consideration, but implemented them really fast!

Overseer Studio is definitively one of those tools I didn't know I so desperately needed. From keeping my DM resources handy, to grouping my own reference guide as player, there is just a lot you can do with a tool like this. Simply amazing!

I discovered Overseer as an application designed to provide a virtual GM Screen, a role it fulfills remarkably well, but its constant evolution during development promises to turn it into something that goes beyond the world of online TTRPGs: reference boards for artists, massive canvas for PDFs, images, and videos for mood boards, and much more. Overseer is an incredibly promising self-hosted digital binder with a wide range of potential uses.

I've used Overseer a handful of times now, and each time I do I learn more and get a better handle of its features in a way that has massively streamlines my prep and my in-game DMing, my players all enjoy that I've adopted Overseer fully into my flow.

Overseer Studio is a desktop application built for tabletop gaming that organizes all the tools a GM uses to run their games. It's not a VTT and it's not a new tool to learn. Overseer Studio simply makes running your games easier and more streamlined. Overseer Studio is offline-first and runs on any Windows, macOS, or Linux computer.
Overseer Studio isn't meant to replace your existing tools. It's meant to work with them and keep you more organized during a game.
For example, if you use OneNote, Obsidian, or any other campaign organizer, you can embed these tools into Overseer Studio for quick access during a game alongside all your other tools and materials.
Running a session can often be chaotic with lots of moving parts. Overseer Studio helps you consolidate your tools into one, easy-to-use screen.
Overseer ships with a handful of useful tile extensions including:
You can also easily install or build extensions to further expand Overseer!
Yes! Overseer Studio was built to be modular by design. You can create extensions, presets, and themes for Overseer Studio and share them however you'd like.
Extensions are embedded websites and can be built with simple HTML, CSS, and JavaScript. You can use the injected Overseer SDK to hook into application events and communicate or listen to other extensions.
$24 for early access users. Once features are finalized, Overseer Studio will be $30 for everyone else. Overseer Studio is a one-time purchase, no subscription fees, with free updates as they're made available.
No. Overseer Studio is offline-first and does not provide a way for players to connect. This also means you do not need to configure ports or host your own server to use Overseer Studio.
If you want to share a particular tile with your players, you can pop out a tile into a new window and share the window over a video call or cast to your living room TV.
As a GM myself, I know how frustrating managing 20 tabs and 5 different programs can be just to run a session; especially when one of your players decides to go off the rails and you're forced to improvise. The last thing you need is the software you're using to get in the way. That's why I built Overseer Studio.
If you were once familiar with Astral TableTop or more recently dddice, then you might know the person behind those tools as the person behind Overseer Studio.
I've learned a lot since building those platforms. The biggest lessons have been:
Overseer Studio was built differently, taking a decade of experience building tabletop gaming applications and applying the lessons learned to make one cohesive, modular, offline-first tool to rule them all.
I'm always open to feedback or questions, email me anytime at tom@overseer.studio.
No.
Overseer is a passion project and I enjoy building each feature based on community input. I do not personally support AI use in creative spaces. If you want to use AI tools with Overseer, nothing is stopping you; but I will never push AI into Overseer.
It's a game. Don't take it too seriously. Have fun :)
