Show HN: Local Privacy Firewall-blocks PII and secrets before ChatGPT sees them https://ift.tt/7rBEDvZ

Show HN: Local Privacy Firewall-blocks PII and secrets before ChatGPT sees them OP here. I built this because I recently caught myself almost pasting a block of logs containing AWS keys into Claude. The Problem: I need the reasoning capabilities of cloud models (GPT/Claude/Gemini), but I can't trust myself not to accidentally leak PII or secrets. The Solution: A Chrome extension that acts as a local middleware. It intercepts the prompt and runs a local BERT model (via a Python FastAPI backend) to scrub names, emails, and keys before the request leav…

Show HN: I built an AI travel planner after wasting 6 hours on Reddit https://ift.tt/0TyihNF

Show HN: I built an AI travel planner after wasting 6 hours on Reddit I'm a dev who got tired of wasting entire evenings planning trips. After the 10th time finding myself with 50 tabs open at 2 AM reading contradictory blog posts, I built Voyaige. What it does: Enter a city + your travel style (budget backpacker, luxury, foodie, etc.) → get a personalized PDF guide in ~15 minutes. Not generic "Top 10" lists—actual itineraries with opening hours, transport tips, and recommendations that match YOUR preferences. Why Perplexity over GPT/Claud…

Show HN: The Box – Run multiple Claude CLI agents in parallel in the cloud https://ift.tt/awTtrSA

Show HN: The Box – Run multiple Claude CLI agents in parallel in the cloud Hey HN, I'm a solo developer and kept running into the same problem: I'd want Claude CLI to work on multiple tasks at once, but locally I could only run one instance at a time. So I built The Box. It lets you spin up isolated sandbox environments in the cloud and run Claude CLI agents in parallel. You write the prompt, pick a GitHub repo, and it handles the rest – creates a branch, does the work, and opens a PR. The core workflow: - Connect your GitHub repos - Create task…

Show HN: Zonformat– 35–60% fewer LLM tokens using zero-overhead notation hey HN! Roni from India — ex-Google Summer of Code(GSoC) @ internet archive, full-stack dev. got frustrated watching json bloat my openai/claude bills by 50%+ on redundant syntax, so i built ZON over a few weekends: zero-overhead notation that compresses payloads ~50% vs json (692 tokens vs 1,300 on gpt-5-nano benchmarks) while staying 100% human-readable and lossless.

Show HN: Axo Pass – Unlock SSH/GPG Keys and Secrets with Touch ID on macOS https://ift.tt/GHosTW3

Show HN: Axo Pass – Unlock SSH/GPG Keys and Secrets with Touch ID on macOS Hi HN! I built an open source macOS app that allows you to unlock your SSH and GPG key passphrases with Touch ID. You can also store secrets and inject them into your dev environment using the CLI, and store `age` encryption keys in the Secure Enclave. I started working on this because I was setting up a new computer, and I didn't like how janky the Mac GPG pinentry tool felt. Secrets management came later because I also wanted an alternative to 1Password's secrets inject…
