Nipun AI is a stock analysis tool that gives you a 25 section research report. Works for both Indian and US stocks. The thing that makes it different from Screener.in or Moneycontrol - it runs three AI models, generates valuation estimates using 3 different methods, fact-checks its own output, and gives you insider trading data and institutional ownership in one place. It's completely free. Uses free-tier APIs. Your API keys are encrypted locally with AES-256 and never leave your browser.

Open-source AI security firewall. 81 engines for PII detection, prompt injection defense, MCP security, and egress classification. Local-first. Zero cloud dependency. Zero telemetry. Zero trust violations.

It sits between your users and your LLM (OpenAI/Anthropic) and strips out sensitive data before it leaves your server. The Tech (Zero AI Inference): Instead of asking an LLM "is this safe?", I use: 152 PII Types: My custom engine covers everything from US Social Security Numbers to Indian Aadhaar cards and HIPAA identifiers. Shannon Entropy: To detect high-entropy strings (API keys, passwords) that regex misses. Deterministic Rules: 100% consistency. No "maybe."

Building with AI? Your users' data is at risk. Every API call to OpenAI, Claude, or Gemini could be leaking SSNs, emails, phone numbers, and 150+ types of PII. Compliance teams are waking up to this. Are you ready? PII Firewall Edge is a zero AI, zero-storage privacy API that runs on Cloudflare's edge network. One API call sanitizes text before it hits any LLM.
