AI document assistant
Dispute a charge, with the bill itself.
Upload the bill or statement. We check the charges against each other and the contract, show what doesn't add up, and write the letter disputing it — line by line.

Not a summary. The next step, done.
Every document gets the same full read — and the paper that answers it.
Risks marked on your document
Every risky clause is highlighted where it sits in your own file. Click a risk, the page scrolls to it.
A checklist per contract type
Leases, jobs, NDAs, freelance, software: a fixed list of protections, each marked present, missing or against you.
A score that doesn't wobble
0–100, calculated from the findings — not guessed. The same contract always gets the same number.
Deadlines into your calendar
Renewal notices, payment dates, deposit returns — one click, with a reminder a week before.
What it could cost you
The worst cases priced with the contract's own figures: leaving early, being late, ending it.
The answer is already written
Objection, appeal, dispute, demand or counter-offer — built from your document's reference numbers, dates and amounts, as a Word file.
Why not just paste it into ChatGPT?
You can. Here is what you don't get.
| Chatbot | FastDocAI | |
|---|---|---|
| Plain-language summary | ✓Yes | ✓Yes |
| Risks highlighted on your own document | ✕No | ✓Yes |
| The same full check on every document | ~Only if you ask, differently each time | ✓Yes |
| Consistent 0–100 score | ~Only if you ask, differently each time | ✓Yes |
| Deadlines to your calendar with reminders | ✕No | ✓Yes |
| Objection or reply written from your document, as Word | ~Only if you ask, differently each time | ✓Yes |
| Every report saved and reopenable | ~Only if you ask, differently each time | ✓Yes |
| File never stored, never used for training | ~Only if you ask, differently each time | ✓Yes |
Chatbots are good at summaries. The difference is the same full check every time, on your document, with outputs you can use.

The correct amount
Worked out from the bill's own figures.
What you ask for
Correction, refund or withdrawal of the charge.
Records asked for
The meter reading, call log or calculation behind it.
Payment in the meantime

Sign inQuestions people ask
Is this legal advice?+
No. It reads your document and drafts the paperwork; it does not promise an outcome. For anything with a lot at stake, show the report and the letter to a lawyer.
What languages does it read?+
Contracts in any major language. The report comes back in the language of this page.
Is my document stored?+
The file is never stored — it is read and discarded. If you're signed in, the report and the letters are kept in your account; delete them any time.
How much does it cost?+
The summary, the deadlines and the top 3 findings are free, no account. A full analysis is 1 credit (up to 10 pages); each letter is 1 credit.
Can it read a scan or a phone photo?+
Yes. Scans and phone photos are read directly — no separate OCR step.
