Tamperlens

Check if a PDF redaction actually removed the text

What it does

Black-boxed a name in a PDF and hit save? The text is usually still there. Tamperlens reads the file's paint order and tells you whether a redaction removed the text or just covered it — free, no signup, and the file is parsed in memory, never stored. Behind it: an API that reports structural fraud signals on PDFs, with evidence and the benign explanation for each. Signals, never verdicts.

    I built a free and open source pdf redaction tool2025 · magicredact.com · ▲5

    Hey everyone, I recently built a free and open-source tool that lets you manually redact PDFs and images right in your browser—no sign-ups, no watermarks. I also added an AI-powered auto-redaction feature to detect and remove sensitive info. Since this part uses external processing (OCR + AI), there are usage limits: you can auto-redact up to 3 single-page PDFs or images for free each day. Higher usage and multi-page support require a paid account. Right now, it works great for removing sensitive details like names, addresses, and emails, but I’d love to get your thoughts: • What redaction…

    Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

  • I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
