    For at least a few years (since before COVID), in my circle everbody wants an AI tool that finds vulnerabilities in binaries. I have my reservations about such a tool because of my perception that AI is overhyped, so I decided to build one myself to see how useful it could be (or not). I was actually kinda surprised how well it worked for my collection of binaries with known CVEs. It definitely has false positives and negatives, as any static analysis tool would, but I think its actually somewhat usable. I dont think the results are super actionable, but interesting nonetheless. I still…

    Hi HN, we're Kiran and Vijay! Over the past two years, we have built a columnar storage engine for observability: logs, metrics, and traces. Today, it's exciting for us to show what we've built on top of that foundation: LLM Agent Observability. Given how non-deterministic agents are, storing all traces without sampling was critical for us. But these traces tend to be in the MBs, sometimes GBs - we needed to store them inexpensively. We also needed the queries and analyses to be fast. To meet both these goals, we store them in S3 in our own parquet-like file format, and query them using AWS…

    Hey HN, solo dev here. After years of frustration with how LLMs handle complex documents, especially PDFs with tables, I decided to build a solution myself. My approach uses a Markdown conversion step to preserve the table structure, which seems to work surprisingly well for chunking. This little parser is the first public piece of a much larger, privacy-focused AI platform I'm building. I'm pretty much running on fumes financially, so any feedback, critique, or support is massively appreciated. Happy to answer any questions about the approach!

    My partner reviews a lot of P&IDs (piping and instrumentation diagrams) and the adjacent files involved (excel, docx, pdfs, acd/l5x, etc). In his company, these are usually done in Bluebeam. It's really hard to see the diff + keep track of all the revisions resulted by these iterations. They end up storing files like "rev3_final_redlined.pdf". We've been looking for something close to Github to do these reviews, but haven't found one easy enough for folks with no CLI experience to understand and use (happy to check out more tools if you know any). So I built withkord.com to help with…

    Hi HN, I built RedactMyPDF.com after struggling to manually redact a large legal PDF, and I found that existing tools were either expensive or clunky. RedactMyPDF uses AI (Gemini) + OCR + human review to make redaction fast but safe: Auto-detects sensitive info based on document context (names, addresses, IDs, etc.) Full control to accept, reject, or add redactions Works on scanned PDFs (OCR with Tesseract) Secure & GDPR-compliant (AES-256, EU storage, one-click deletion) Irreversible blackouts + metadata removal Audit logs (CSV export for compliance) Try it here: www.redactmypdf.com Thanks!
