Show HN: Pixrep – Turn code repositories into PDFs for multimodal LLMs

Hacker News - Thu, 02/19/2026 - 4:03am

Hey HN, creator here.

I've been experimenting heavily with large-context multimodal LLMs (like Gemini 3 Pro) for coding tasks. I noticed that feeding raw text files consumes a massive amount of tokens and often clutters the context window.

Inspired by recent research (like the DeepSeek-OCR paper) suggesting visual encoders can be more efficient than text tokenizers for structured data, I built pixrep.

It’s a CLI tool that converts your codebase into a structured, syntax-highlighted PDF hierarchy.

Key features: - Token Efficiency: In my local benchmark, a repo requiring ~31k text tokens was compressed to ~19k tokens when fed as a visual PDF (using the `onepdf` mode). - Semantic Minimap: It uses Python's `ast` (and regex for other langs) to generate a UML/call-graph minimap at the top of each file. - Linter Heatmap: It can run `ruff` or `eslint` and overlay a heatmap on the PDF to warn the LLM about risky lines visually. - OnePDF Mode: Packs the core code into a single, ASCII-optimized PDF file for single-shot uploading.

It's written in Python and uses ReportLab for PDF generation.

I'd love to hear your thoughts on "Visual RAG" or any feedback on the implementation!

Show HN: Free developer utility API – QR, fake data, URL shortener, 40 tools

Hacker News - Thu, 02/19/2026 - 4:00am

I built a free REST API for common dev tasks that usually require pulling in heavy dependencies or writing boilerplate.

Features include: - URL shortener with click analytics - QR code generation (PNG/SVG/data URL) - Fake/mock data generator (person, address, email, company, etc.) - JWT decoder, regex tester, password generator - JSON diff/format/minify, YAML↔JSON, Markdown→HTML - Base64, SHA256/MD5/SHA512 hashing, UUID v4 - Cron expression explainer, number base converter - IP info, HTML tag stripper, list processor

No auth required for basic usage (rate limited). Pay 1 USDC on Base L2 for an unlimited API key.

Also available as a zero-dependency npm package: npm install conway-toolbox
