In plain English

It renews for another year on its own. To get out, you must send written notice 90 days before the end date. Easy to miss.

What to ask for

30 days' notice instead of 90, or a written reminder from them 60 days before renewal.

01The problem

Signed on Friday.Regretted in month thirteen.

A small online store signs supplier terms, NDAs and software agreements all the time, and a lawyer for each one is out of the question. So contracts get skimmed, and the clauses that hurt later get missed: the auto-renewal, the price change, the liability cap worth one month of fees.

Before
  • Pages of legal language skimmed in a hurry
  • A lawyer only when something already went wrong
  • No idea what is normal, or what to push back on
  • Renewal deadlines in nobody's calendar
With Contract Blitz
  • Every clause explained in plain English
  • The risky ones flagged before signing
  • What to ask for, ready to send back
  • A reminder before every deadline that matters
02How it works

Read like a lawyer.Talk like a friend.

Tap any step to see what happens there. Every explanation and every flag stays tied to the line it came from, so the seller can always check the original wording.

Step 2

Read. The contract is split into its clauses, and each one is read on its own, with its section number kept.

03The clause that bites

The date on the contractis not the date that matters.

An auto-renewal with a notice period is the classic trap. Everyone remembers the renewal date. Almost nobody remembers that the last day to cancel was three months earlier.

Contract Blitz pulls both dates out of the contract and puts reminders before the one that matters. Change the notice period below to see how far the real deadline moves.

Notice period in the contract
Too late to cancel
Signed1 Mar 2026
Reminder30 days before
Reminder7 days before
Last day to cancel1 Dec 2026
Renews for a year1 Mar 2027
  1. Signed1 Mar 2026
  2. Reminder1 Nov 2026
  3. Reminder24 Nov 2026
  4. Last day to cancel1 Dec 2026
  5. Renews for a year1 Mar 2027

The renewal date is easy to remember. The date that matters is 1 Dec 2026, 90 days earlier, and that is the one people miss.

04One place for every contract

Not a one-off scan.A home for every contract.

Each review is saved, so the store ends up with every agreement in one place: what is active, what expires soon, what still needs a look.

05How we built it

If it can't point to a line,it doesn't say it.

The first objection to AI in legal work is always the same: how do I know it didn't make that up? For a seller deciding whether to sign, a confident wrong answer is worse than none.

So every explanation is grounded in the contract's own text. The clause is retrieved first, the explanation is written from it, and the flag links back to it. Nothing is said about a contract that is not in the contract.

Step 1

Contracts split into clauses with their section numbers, stored for retrieval.

Step 2

Plain English

Explanations and risk levels written for sellers, not lawyers.

Step 3
