LocalLens
What it is
LocalLens is an offline visual search engine for local image and video collections. It recursively indexes folders into ChromaDB, then lets you search with text descriptions and ranks matching media by similarity. You can upload an image to locate visually similar files, or combine an image with text to refine results. A duplicate finder identifies duplicate and near-duplicate image pairs using a similarity threshold. Listed formats include JPG, PNG, WebP, MP4, and MKV. LocalLens offers a Gradio web interface and a command-line interface, and can synchronize indexed folders when files are added or removed. Supported vision backbones include SigLIP 2, MetaCLIP, DFN-CLIP, and CLIP. Portable builds are available for Windows, Linux, and macOS. Linux and macOS require Python 3.10 or newer and Git. The documented baseline is a 4-core CPU, 8 GB RAM, no VRAM, and 20 MB storage. It is open-source under Apache-2.0 and free.
For and against
For
- Offline search for local media
- Text and reverse-image queries
- Duplicate and near-duplicate detection
- Web and command-line interfaces
- Open-source Apache-2.0 license
Against
- Linux and macOS require Python 3.10+ and Git
- Gallery can access indexed directories by default
- Recommended hardware exceeds documented baseline
The verdict
LocalLens combines text search, reverse-image matching, and duplicate finding for locally stored media. Its offline, open-source approach and broad desktop availability suit personal collections, provided the directory-access setting and hardware needs fit your setup.
Who it suits
It suits people organizing local image and video libraries who want text, image, or duplicate searches. It is available through web and command-line interfaces on Windows, Linux, and macOS.
