Paste a contract — get a plain-language summary and three gotchas

Here's the idea in one line: you paste the text of a contract, terms of service, or a subscription's fine print — and the app returns a short plain-language summary plus a «look at this» list: where the auto-renewal is, where the penalty is, what you're giving up.

Here's what's new. Reading a long document for you and finding the traps in it used to take an expensive, slow model — running it on every contract wasn't worth it. Gemini 3.5 Flash, in Google's words, does «deep reasoning across long horizons» and reads up to a million tokens — that's hundreds of pages — at Flash speed and Flash price. So «reading the fine print» dropped to pennies. That's what the project rides.

Why this one

Nobody reads the fine print. You tap «I accept» — and a month later you're charged for a whole year at once. You rent a flat — and clause 7.3 has a penalty for leaving early. The problem isn't that it's written in hard language. It's that there's a lot of it, and the important part is hidden between the lines. The model doesn't get tired of reading — and it pulls out exactly the three or four lines the whole thing was about.

There's less magic here than it looks. The app is one pipe: the long text goes to the model, a summary and a risk list come back. All the work is in one precise request.

What you'll learn

• Feeding the model a long text. Not a couple of phrases, but a whole document as input — and a sensible answer out.
• Asking for specifics, not «summarize». «Find auto-renewal, penalties, and what I'm giving up» hits harder than «what's this contract about».
• Pulling a verbatim quote. Have the model return not just the conclusion but the clause itself — so you can check it, not take it on faith.

A ready starter prompt

Don't ask «summarize the contract» — you'll get a smooth paragraph about nothing. Say what to look for and in what shape:

The strong prompt sets both the task and the shape: you get a summary plus a list with verbatim quotes you can show on screen, not vague words. And «don't invent», with a quote next to each point, is your insurance against the model making something up.

What you end up with

You paste a service's subscription terms. A second later: «You pay 990 ₽ a month for access, renewal is automatic». Below, three cards: «Auto-renewal — you'll be billed for a year unless you cancel 3 days ahead», with the exact clause quoted. You didn't read ten screens — but you know where the catch is. It's a helper, not a lawyer: double-check anything serious — but now you at least know what to double-check.

Start with the summary, build up to a list of gotchas with quotes — and fine print stops being the thing you sign blind.
