PISIGuard: Protect your personal and sensitive info when you chat with AI

šŸ“ Discussion Summary (Click to expand)

3 Most Prevalent Themes

1. Need for Context & Comparison

Users repeatedly ask the author to clarify how the project differs from existing tools and to acknowledge prior art.

"Personally I love when projects mention whether they’ve found other existing software that does something similar, and if so how this app compares." – no‑name‑here

"There’s stuff like https://presidio.dataprivacystack.org originally from Microsoft." – no‑name‑here

These comments highlight that readers want a clear statement of novelty and a brief comparison with known alternatives.


2. Accidental Leakage & ā€œLazy‑Censorā€ Utility

Several participants point out that the real value lies in preventing accidental exposure of personal data, especially when users are lazy or unaware of leaks.

"It could be useful more as a labor saving device to enable censoring while allowing the human to engage in easy copy‑paste." – frumiousirc

"I find it amusing how a lot expect people to ā€˜not be lazy’, people are mostly lazy and even sometimes clueless about how much they leak to BigCorps." – mohamed_am83


3. Requests for Expanded Reach & Practicality

There are multiple suggestions to broaden the tool’s appeal—e.g., making it work in browsers, CLI agents, or locally for code obfuscation, and targeting non‑technical users.

"I’m not sure whether this project is truly practical in its current form. More and more people are using AI agents through CLI tools or desktop applications, so I think you should consider extending it to run locally." – toto007

"The core is plain JS so it is easy to make a plugin, but I believe there are many plugins already for common coding agents. I wanted to target the less savvy and non‑coder people who treat chatgpt and friends like the new google." – mohamed_am83

These points stress that the project’s future success may depend on extending its scope beyond simple web‑AI interactions and making it accessible to a wider, possibly non‑technical audience.


šŸš€ Project Ideas

AI Prompt Anonymizer Chrome Extension

Core Feature Real‑time detection and replacement of PII/PCI in typed prompts with safe placeholders
Tech Stack JavaScript/TypeScript, Chrome Extension API, regex rule engine
Difficulty Medium
Monetization Revenue-ready: Freemium with premium rule packs ($4/mo)

Notes

  • Addresses the exact pain point raised by users who leak identifiers to LLMs and want a simple safeguard.
  • Leverages the popularity of browser extensions to reach HN’s tech‑savvy but non‑developer audience.

LogSanitizer CLI

Summary

  • Scans command output or log files for identifiers and replaces them with configurable placeholders.
  • Enables developers to automatically anonymize logs before sharing with LLMs or external services.

Details

Key Value
Target Audience Developers, DevOps engineers, researchers who generate logs sent to AI tools
Core Feature Command‑line tool that processes stdin/stdout, applies redaction rules, and outputs sanitized text
Tech Stack Rust, Clap, regex patterns, optional JSON output
Difficulty Medium
Monetization Hobby

Notes

  • Solves the frustration expressed by users who accidentally expose personal info in CLI output before feeding it to AI agents.
  • Offers a practical utility that can be integrated into CI pipelines, satisfying HN’s demand for tangible productivity gains.

Enterprise AI Data Guard SaaS

Summary

  • Provides a cloud‑based gateway that intercepts outbound AI API calls, redacts sensitive fields, and injects placeholders while preserving mapping for audit.
  • Lets enterprises securely use external LLMs without risking data leakage.

Details

Key Value
Target Audience Enterprises, compliance teams, SaaS platforms integrating third‑party LLMs
Core Feature Server‑side proxy that sanitizes request payloads, stores placeholder mappings, and restores them for internal analysis
Tech Stack Node.js backend, React UI, OAuth2/AppAuth, serverless functions
Difficulty High
Monetization Revenue-ready: Per‑user monthly subscription

Notes

  • Directly responds to the need for a more robust solution than browser extensions, addressing HN discussions about DLP‑style tools for AI.
  • Offers clear commercial potential and opens avenues for integrations with existing enterprise security stacks.
