Prinn – Stop secrets leaving your business when using AI without slowing work launched on September 9, 2026.
In plain words
Prinn is a device-level security tool that prevents sensitive data from being sent to AI services like ChatGPT, Claude, and Copilot. It scans prompts in milliseconds to detect and flag API keys, passwords, bank details, and other confidential information before they're transmitted. Designed for small teams rather than large IT departments, Prinn runs locally on Mac and Windows computers, keeping all data private without storing or sending information to external servers. It allows teams to use AI tools without slowing their workflow while protecting business secrets from accidental leakage.

LocalAug 2026 · basecompute.co · ▲107Super excited to launch our new app Local today. What we’ve learned at Base Compute over the last months is that running AI directly on your laptop or workstation gives you maximum privacy and it’s free, but it’s also a massive headache to configure. So we’ve decided what matters is making the experience completely frictionless for users. Local analyses the hardware of your laptop, optimises the AI for it, and recommends the best models for your specific device. It let’s you do what you’re doing with cloud AI already, just for free and on your own machine: Chatting with PDF’s, Recording and…
Local Privacy Firewall-blocks PII and secrets before ChatGPT sees themDec 2025 · github.com · ▲111OP 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 leaves the browser. A few notes up front (to set expectations clearly): Everything runs 100% locally. Regex detection…
