Practical overview
When it fits
Use Captain when you want a desktop interface for local AI workflows and meet its documented Windows, NVIDIA GPU, CUDA Toolkit, and driver requirements.
Who it is for
- Windows users with NVIDIA hardware who want to explore locally run AI models.
- People looking for a desktop launcher and dashboard to find, install, and manage AI apps.
- Users interested in creating images and generating stories from images.
Documented uses
- Launch built-in AI apps from a keyboard-driven Prompt.
- Find and install AI apps through a dashboard marketplace.
- Run AI models on a computer without an internet connection.
- Create artwork with Live Painting and generate narratives from images with Story.
- Search images, stories, and documents in a local vector database with Explorer.
Requirements & limits
The project documents a Windows installer and labels Captain alpha. Its README lists macOS and Linux as coming soon.
- The README identifies Windows with an NVIDIA GPU, NVIDIA CUDA Toolkit for Windows, and a current NVIDIA driver as the setup Captain currently works best with.
- The installation may download large files and can ask for Qdrant network access.
- The project is open source under the AGPL-3.0 license.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Install Captain on a Windows PC
Install the alpha desktop app using its documented Windows setup path.
Before you start
- Windows PC with an NVIDIA GPU
- NVIDIA CUDA Toolkit for Windows
- Latest NVIDIA driver for the GPU
Steps
Download the Captain installer from the project’s releases page.
Open the installer and choose an installation location.
Follow the installer instructions and allow time for large files to download.
If prompted, allow Qdrant network access so Captain can operate.
Expected outcome
The README says Captain starts after setup is complete.
Guide limitations
- Captain is labeled alpha and the project says the listed Windows and NVIDIA setup is where it currently works best.
- The README warns that Windows may show a warning because the alpha installer is not signed by Microsoft.
Open built-in apps from Captain’s Prompt
Use the Prompt to find and start a documented built-in AI app.
Before you start
- Captain installed and started
Steps
Open the Prompt with Ctrl+Alt+Space.
Enter a request such as “I want to draw something” and select Live Painting, or enter “Create a story” and select Story.
Expected outcome
The selected built-in app opens for artwork creation or story generation based on images.
Guide limitations
- The README documents these app-selection examples but does not specify model settings or generation parameters.
