SWALL-E

• 

  Built for Security. Designed for Privacy.

Inspiration

Inspired by this Hackathon's Fireside Chat speaker, Gautam Krishnamurthi, that one of the growing concerns on the use of AI is security, sharing of information to LLMs and on-premise implementation, we came up with a tool to prevent sharing company information.

What it does

Our Chrome Extension, Privacy Firewall, acts as a real‑time Data Loss Prevention layer between employees and external AI tools like ChatGPT, Gemini, and Claude. Instead of sending sensitive corporate data to third‑party servers

How we built it

Privacy Firewall uses a 100% local, offline LLM (Phi‑3 via Ollama) to automatically detect and redact confidential information before it ever leaves the browser. No cloud calls. No data exposure.

Challenges we ran into

Setting up the local model and training it.

Accomplishments that we're proud of

To be able to do real time text detection and be able to redact it

What we learned

Importance privacy and the need to not overshare to AI

What's next for SWALL-E

Pro version! We are planning to allow PDF upload integration for an annual/monthly subscription.
