What it does
rec-format converts any PDF into a compact, AI-optimized format that uses ~100 tokens per page instead of ~1,600. A 16× reduction with zero information loss. Unlike raw Markdown,rec preserves page references, embeds metadata, guarantees file integrity via SHA-256, and supports images for vision-capable models. The result: academics, students, and developers can feed entire documents into AI context windows that would otherwise overflow at a fraction of the cost.
Convert any PDF to .rec — a compact, structured format that uses 16× fewer tokens. Works with ChatGPT, Claude, and Gemini. Free and open source.
.rec is a new open format that converts PDFs into something AI can actually consume efficiently. ~100 tokens per page instead of ~1,600, with page references, embedded metadata, and a verifiable schema — structure that raw Markdown simply doesn't have. Same document. Same information. 16× cheaper. Drop any PDF below — get a .rec file ready to paste into Claude, ChatGPT, or Gemini. You feed papers, theses, and reports to AI for literature reviews, summaries, or Q&A. A single 40-page paper costs ~64,000 tokens as PDF. With .rec, that's under 4,000. Process entire libraries without burning through API credits. You use AI to understand lecture notes, textbooks, and course materials. Free-tier…from recformat.com

Markdown Converter 2025 · markdownconverters.com · ▲12Hey HN I built MarkdownConverters.com — a tool that converts any file format (PDF, DOCX, PPTX, HTML, or URL) into clean, structured Markdown. I often needed to prep documents, reports, or scraped pages for AI pipelines, documentation, or version control, but existing tools either broke formatting, lost code blocks, or produced unreadable Markdown. So I built something that focuses on: • Accurate structure (headings, lists, tables, code, links) • Consistent Markdown output ready for LLMs or docs • Fast, browser-based conversion with privacy-friendly processing • Support for multi-format and…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
