About This Software

Find that one image in your head — with a single sentence

Tens of thousands of images sit on your drive with meaningless filenames and no tags. But you remember that one picture — "sunset at the beach."

ShiGuang is a fully local AI semantic search engine. Type what you're thinking, and it understands the visual content directly, instantly locating the exact image from your massive library.

Why ShiGuang?

• 100% Local, Zero Privacy Concerns — All AI models are built in. Your images never leave your computer. Works offline. No account, no cloud, no telemetry.

• Ready Out of the Box — No dependencies to install. Set it up like a game and start searching.

• AI Re-Ranking — Exclusive two-stage retrieval: broad vector search first, then a reranker model refines the top candidates. Far more accurate than ordinary solutions.

• Search Video Content Too — Videos are automatically frame-indexed. Type "a cat rolling over" and jump straight to the right video.

Four Ways to Search

• Text to Image — "Girl in a red dress", "cyberpunk street" — search exactly how you think

• Image to Image — Drop in a reference image to find every similar scene in your library

• Text + Image Combined — Reference image and text description work together in a single multimodal inference

• Negative Prompts — Unique "-" exclusion syntax: "landscape -night -black and white" for ever-sharper results

More Capabilities

• Video Frame Search — Supports MP4 / MKV / AVI / MOV / WebM and more. Smart scene-detection frame extraction; click a result to preview the exact moment

• Smart Quality Filtering — Automatically filters out blurry, pixelated, or solid-color junk images during indexing for a cleaner library

• Auto Long-Image Splitting — Long screenshots and webtoons are automatically split and indexed, so individual sections are searchable

• Smart GIF Frame Selection — Automatically picks the most representative frame

• Asset Management — Favorites, custom color tags, excluded folders, and library content insights

• MCP Protocol Support — Plug it into your AI assistant as a tool and let AI search images for you

• 9 Carefully Crafted Themes — From minimal solid colors to the animated "Molten Sunset" lighting theme

Built for Performance

• GPU Acceleration — Supports NVIDIA / AMD / Intel (Vulkan). Turbo-mode searches finish in under a second on modern GPUs

• Runs Without a Dedicated GPU — Automatically falls back to multi-core CPU mode

• HNSW Vector Index — Millisecond response even on 100,000+ image libraries

• Virtual Scrolling — Buttery-smooth browsing through massive result sets

Who Is It For?

• Designers, illustrators, and photographers hoarding terabytes of assets

• Gamers and content creators buried under mountains of screenshots

• Video editors who need to locate specific shots in their footage library fast

• Anyone who wants image search but never wants to upload to the cloud

ShiGuang — Every image deserves to be found.
