One click: Install offline engine
Setting up ComfyUI used to mean Python, model folders and custom nodes. Now it is one button in Settings → Engine.
Already have ComfyUI? Choose Add to my ComfyUI and Bloop Studio adds only the models your card is missing.
-
Checks your graphics card
Bloop Studio reads your GPU, its memory and your free disk space, and tells you plainly what it can render.
-
Suggests the models it can run
The models your card can handle come ticked: pictures, video with sound, quick silent drafts.
-
Downloads ComfyUI and the models
Straight from their publishers. Downloads resume after an interruption and every file is checked.
-
Starts it for you
The engine starts with the app and stops when you close it. No .bat files, no terminal.
From download to first shot
-
Download and install
Run the installer and pick a folder; it adds Desktop and Start menu shortcuts. Windows may say "Windows protected your PC" because the installer is not code-signed yet: choose More info → Run anyway.
-
Choose online, offline or both
Press Install offline engine to render on your GPU, or sign in with bloop to render in the cloud. You can do both.
-
Make your first shot
New space, add a Text card and a Video card, wire one into the other and press Generate. Progress and time left show on the card.
A film board, not a node graph
Bloop Studio picks the right workflow for your PC behind every card. You think in shots; it handles the rest.
A wired story board
Text, Image, Video, Upload and Note cards. Drag a wire from one card to the next and the story reads left to right.
Video with sound
Describe the rain on the roof and the distant thunder in the words, and the clip comes back with them.
First frame to last frame
Wire one picture in as the first frame and another as the last, and the clip travels from one to the other.
Same cast in every shot
Wire one Cast card and one Location card into every shot, so people and places look the same throughout.
The Director, if you want it
A chat that lays out cast, locations and shots on the board for you. Bring your own Claude or OpenAI key.
Every take kept, always up to date
Renders are saved to your Videos folder as takes. The app updates itself and keeps your boards.

What's new
Bloop Studio updates itself: a new version shows Restart to update in the top bar.
Version 2026.1005.1232
- Changed: the Director now works like bloop's. On a new board it plans first: a pitch, the cast, the places and the shots, and at most two questions. After your answer it lays the cast and the places, then writes every shot in the background (you see each lane land), with the camera, the sound, the lines and the music. It checks its own work and never claims a change that didn't land. Its replies are formatted text.
- New: Image cards take up to three pictures. With two or more, the still is drawn from them on Qwen-Image-Edit 2511 (the same faces, outfits and places), and the Director wires each shot's cast sheets into its still. Qwen-Image-Edit is in the engine installer.
Version 2026.1005.1156
- Fixed: a card no longer sits on "generating" forever when ComfyUI is restarted mid-render. It now stops with a message after about 20 seconds, so you can generate it again.
Version 2026.1005.1134
- Fixed: Audio cards show their progress again while they render (the percentage, the bar and the step).
Version 2026.1005.1122
- Changed: cards take the real shape of their clip or picture. A vertical clip makes a tall card instead of sitting in a wide box with black bars, on rendered cards and uploads alike.
Questions
Is it really free?
Yes. The app is free, and everything you render on your own graphics card is free, with no account. Only bloop cloud models use bloop credits, and those are optional.
Do I need to know ComfyUI?
No. Bloop Studio runs ComfyUI for you behind the cards. Install offline engine sets it up, picks the models and starts it. You never open it.
Windows says "Windows protected your PC". Is that safe?
The installer is not code-signed yet, so Windows SmartScreen asks first. Choose More info, then Run anyway. The installer comes from our official GitHub releases page.
How do updates work?
Automatically. The app checks for a new version when it starts and every few hours, downloads it in the background and shows Restart to update. Your boards, settings and renders are kept.
My graphics card is not strong enough. Can I still use it?
Yes. Sign in with a bloop account and Bloop Studio works cloud only: cards use bloop's models and no local engine is needed. New accounts start with 60 free credits.
Does it work on AMD cards?
In beta, on AMD cards with 16 GB or more, for pictures and silent draft clips. Video with sound on your own GPU needs an NVIDIA card with 12 GB or more.
Where are my renders saved?
In Videos\Bloop Studio in your user folder, or any folder you choose in Settings. Offline renders never leave your PC.
What does the bloop account add?
Bloop's cloud models on every card. A free account gets the lower-cost models on its free credits; Lite and above get every model. Sign out any time.
Your next film starts on a board
