Web scraping will never be the same.
(100% open-source visual search at scale)
PixelRAG is a retrieval system that skips HTML parsing completely.
Instead of scraping a page into text and embedding chunks, it screenshots the page and retrieves the image. A vision-language model reads the answer straight off the pixels.
Why that matters: parsing is where web RAG quietly loses information.
- A single HTML-to-text parser can drop 40%+ of a page.
- Tables, charts, and layout get flattened or thrown out.
- Swapping parsers alone can move accuracy ~10 points on the same docs.
PixelRAG indexes the page a person actually sees. The team built a visual index of all of Wikipedia, 30M+ screenshots, and it still beats the strongest text RAG baseline by 18.1% on text-only QA.
The repo also ships a Claude Code plugin that gives Claude eyes.
It lets Claude screenshot any URL and read the rendered page instead of scraping the DOM. So you can hand it a live page, an arXiv paper, or your local site and ask what it actually looks like.
One setup script. No MCP server, no backend.
How the pipeline works:
- Renders each document (web, PDF, image) to image tiles.
- Embeds them with Qwen3-VL-Embedding, LoRA fine-tuned on screenshots.
- Builds a FAISS index and serves a search API.
A stronger reader model lifts accuracy with no re-indexing, since the index is just pixels.
Everything is open-source under Apache-2.0.

Talking about RAG, I recently wrote an article on a new approach that makes retrieval much more efficient by cutting corpus size by 40x, reducing tokens per query by 3x, and improving vector search relevance by 2.3x.
The article is quoted below.
programming without math keeps you at the surface.
you can build apps.
write APIs.
move data around.
but the deeper systems need math.
graphics
cryptography
compression
machine learning
simulations
optimization
signal processing
math for programming by ronald t. kneusel
is about the math hiding underneath real software.
not math as classroom decoration.
math as machinery.
vectors tell objects where to move.
matrices transform space.
probability handles uncertainty.
logic structures computation.
calculus tracks change.
number theory secures communication.
the better your math gets,
the more software stops looking like syntax
and starts looking like systems.
Ready to master UI Toolkit in Unity 6? 💻✨
