I Built Termsight: An AI That Reads the Privacy Policy So You Don't Have To.

What I Built

Termsight is an AI tool that reads privacy policies and terms of service
and explains them in plain English, so you don't have to.

Paste in a policy (or a link to one), and Termsight breaks it down into
four things people actually care about: what information is collected,
how it may be shared with third parties, how long it's retained, and
what rights you might be giving up. Every finding links back to the
exact section of the original document it came from — and if the
policy doesn't clearly answer something, Termsight says so instead of
guessing.

The lazy payoff: nobody has to actually read pages of legal text
anymore just to know what they're agreeing to. Anyone who's ever
clicked "Accept" without reading gets to be a little lazier and
better informed at the same time.

How I Built It

Termsight runs on Qwen2.5-1.5B-Instruct, an open-weight language
model, loaded and run locally rather than called through a commercial
AI API. The interface is built with Streamlit.

The pipeline:

The pasted policy (or fetched URL content) is split into numbered sections
For each of the four categories, a focused, single-question prompt is sent to the model asking it to answer using only what's in the document, and to explicitly say "Not specified in this document" when something isn't addressed
Each answer is required to cite the section number(s) it came from

I deliberately split the analysis into four separate, focused prompts
rather than one big prompt asking everything at once with a smaller
model, this made a real difference in answer quality and prevented the
model from just dumping bare citations instead of actual explanations.

Why Does Open Innovation Matter?

Privacy policies are sensitive by nature pasting one into a
commercial AI service means trusting yet another third party with that
text, which is a strange thing to do for a tool whose whole purpose is
helping you protect your privacy.

Because Termsight runs on an open-weight model instead of a closed API,
the policy text is never sent to a third-party AI service. That's not
just a technical detail it's the actual point. A tool meant to help
you understand what you're agreeing to shouldn't require agreeing to
something new (sending your data elsewhere) just to use it. Open models
make that kind of honest, self-contained tool possible in a way a
closed API fundamentally can't.
