SecureBin.ai
Encrypted pastebin — your data never touches our servers
What it does
SecureBin.ai encrypts everything in your browser before it ever reaches our servers. We literally cannot read your data. AES-256-GCM encryption (military-grade) Zero-knowledge decryption key stays in the URL fragment, never sent to servers Burn after reading self-destructing messages Password protection with PBKDF2 (600K iterations) Encrypted file sharing (PDFs, images, docs) 20+ free developer tools built in No sign-up, no tracking, no cookies 100% serverless on Cloudflare Workers

- HSHidetext.sh – encrypted pastebin where the server never sees the keyJul 2026 · hidetext.sh · ▲7
Hi HN! I built hidetext.sh — a way to share text, code, and files through links the server can't read. How it works: your browser generates a random key and encrypts everything locally (NaCl secretbox, XSalsa20-Poly1305). Only ciphertext is uploaded. The key goes into the URL fragment — the part after # — which browsers never send to servers. The link carries the key, my server stores the locked box, and the two only meet in a browser. A design detail I'm fairly happy with: burn-after-read doesn't destroy the paste on the first HTTP request. The naive version means a Slack or iMessage link…

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…
