The project, built by StarTrail-org, includes components for rendering, embedding, indexing, serving, and training, and integrates with Claude Code via a plugin. It enables visual understanding of tables, charts, and infographics, differing from traditional text-based RAG.", "body_md": "PixelRAG is a visual RAG tool that treats web pages, PDFs, and images as *screenshots* rather than text — preserving the layout of tables and charts so you can search and reference them as-is.\n\nThis post covers installing it as a plugin, actual usage, how it differs from traditional text-based RAG, and the gotchas you're likely to hit — all from a Claude Code user's perspective.\n\n**What you'll get out of this post**\n\nPixelRAG renders documents — web pages, PDFs, images — as screenshots and feeds those images directly to the model. The visual structure that HTML parsing normally destroys — tables, charts, layout, infographics — stays intact, so the model can actually answer questions about them.\n\nPixelRAG is an open-source project built around \"Visual Retrieval-Augmented Generation,\" made up of 5 components:\n\n| Component | Role |\n|---|---|\n`pixelrag-render` |\nConverts documents (web pages, PDFs) into image tiles (via Playwright/CDP) |\n`pixelrag-embed` |\nVectorizes tile images and builds a FAISS index |\n`pixelrag-index` |\nRuns the full source → ingest → embed → index pipeline |\n`pixelrag-serve` |\nServes a FAISS search API (CPU/GPU) |\n`pixelrag-train` |\nFine-tunes Qwen3-VL-Embedding via LoRA |\n\nThese are all now bundled into a single `pixelrag`\n\npackage, installable with one `pip install pixelrag`\n\n. As a Claude Code user, the first thing you'll actually touch is the `pixelshot`\n\ncommand (shipped by `pixelrag-render`\n\n) and the \"pixelbrowse\" plugin that wires it into Claude Code.\n\n``` php\nflowchart LR\n    A[URL / PDF] --> B[\"pixelshot<br/>(generates image tiles)\"]\n    B --> C[\"tile_0000.jpg ...\"]\n    C --> D[\"Claude Code's Read tool\"]\n    D --> E[\"Claude understands it visually\"]\n    C -.->|optional| F[pixelrag-embed / index]\n    F --> G[FAISS index]\n    G --> H[pixelrag-serve search API]\n```\n\n**How this differs from traditional text RAG**\n\nSetup is straightforward: either clone the repo and run it locally, or add the plugin via the marketplace.\n\n`requires-python`\n\nin `pyproject.toml`\n\n)`pyproject.toml`\n\nincludes `environments = [\"sys_platform == 'linux'\"]`\n\n, meaning the GPU-dependent parts (`embed`\n\n/`serve`\n\n/`train`\n\n) assume Linux. This shouldn't matter much if you're only using the screenshot feature (`pixelshot`\n\n), but on Mac/Windows you're safer running it through WSL.`pixelshot`\n\nscreenshot feature just runs Playwright/Chromium locally, so there's no extra cost beyond your normal Claude Code token usage. Building your own index with `embed`\n\n/`serve`\n\n/`train`\n\n, however, needs a GPU, and if you use a cloud GPU for that, you'll pay for that usage separately.The official `plugin/setup.sh`\n\nlooks like this:\n\n``` bash\n#!/bin/bash\n# One-liner that installs pixelrag and registers it as a Claude Code plugin\nset -e\n\n# Install pixelrag into an isolated environment via uv\nuv tool install --from \"$REPO_DIR\" pixelrag 2>/dev/null || \\\n    uv tool upgrade --from \"$REPO_DIR\" pixelrag\n\n# Install Chromium for screenshots\nuvx playwright install chromium 2>/dev/null || true\n```\n\n**Option 1: Clone the repo and run it locally**\n\n```\ngit clone https://github.com/StarTrail-org/PixelRAG.git\ncd PixelRAG\n./plugin/setup.sh\nclaude --plugin-dir ./plugin\n```\n\n**Option 2: Install via the marketplace**\n\n```\npip install pixelrag                                # installs the pixelshot command\nclaude plugin marketplace add StarTrail-org/PixelRAG\nclaude plugin install pixelbrowse@pixelrag-plugins\n```\n\nWith the plugin installed, Claude is set up to call `pixelshot`\n\nvia Bash and then read the generated images with the Read tool.\n\nOnce installed, you just pass a URL in regular conversation and it works.\n\n```\nclaude -p \"Look at https://news.ycombinator.com and summarize the top stories\"\n```\n\nIn an interactive session, you can also use the slash command:\n\n```\nclaude --plugin-dir ./plugin\n# inside the session\n/screenshot https://example.com\n```\n\nUnder the hood, Claude runs something like the following `pixelshot`\n\ncommand via Bash:\n\n```\n# Screenshot a URL (tile height optimized to 1568px for Claude's vision model)\npixelshot https://example.com --output /tmp/pixelbrowse --tile-height 1568 --wait-network-idle\n\n# Process multiple URLs in parallel\npixelshot url1 url2 --output /tmp/pixelbrowse --tile-height 1568 --wait-network-idle --workers 4\n\n# Render a PDF\npixelshot document.pdf --output /tmp/pixelbrowse\n```\n\nOutput is saved with a naming pattern like `/tmp/pixelbrowse/<domain>.png.tiles/tile_0000.jpg`\n\n, and Claude reads it in as an image to understand the content.\n\nThe following notes come straight from the official SKILL.md and matter in practice.\n\n**Forgetting --wait-network-idle gives you a blank page**\n\n**Stick with the default --tile-height of 1568px**\n\n**If text is too small to read, crop and re-read it**\n\nThe official workflow is to crop the relevant region with Pillow and feed it back through the Read tool.\n\n**Where PixelRAG is useful**\n\nPixelRAG specializes in exactly what traditional text RAG struggles with: searching documents while preserving tables, diagrams, and layout.\n\nWiring it into Claude Code doesn't require an MCP server at all — it's a skill-only setup that comes down to a single `pixelshot`\n\ncommand.
