50+PDF tools that run on your device. Unlimited. Free
What it does
Every "free" PDF tool online quietly uploads your contracts, invoices, even your Aadhaar to a server you'll never see - then charges you a subscription for it. We build sovereign AI at ModelCam — data stays on your machine, never the cloud. So we asked: why should a PDF be different? hamarapdf runs 50+ PDF tools entirely in your device. Scan, merge, split, compress, convert, sign, redact, OCR, plus GST invoices for SMEs. Nothing uploads. Open your network tab and watch. Free, forever.
hamarapdf is a free-forever PDF toolkit — 55 tools to merge, split, compress, convert, sign, OCR and edit PDFs. Core tools run on your device; your files never leave it. No login, no signup.
Scan , merge, split, convert, compress, sign , edit, redact and OCR — these all run locally on your device. NO upload, NO account, NO watermark, NO limits — FREE forever. Want it offline? A desktop app is coming soon. Draw, type or upload your signature — placed on-device, never uploaded. Private AI that reads your documents on your own engine — never a public cloud. Launching shortly for the AI tier. Five intelligence tools that read, extract, summarise, translate and redact — running entirely on your own engine. Launchingfrom hamarapdf.com

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…

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.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

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…
