₹20 lakh to ₹25 lakh
Who you sell to
Customers in India and abroad
First version
One person can build it with AI tools
What it is
Install the extension, open any terms and conditions page or paste a contract, and it gives a short plain-language summary. It points out what you are agreeing to, fees and penalties, how your data may be used, and clauses that look one-sided. A free tier covers a few documents a month. Paid users get unlimited documents and deeper risk checks. Small businesses could pay for bulk analysis, and the summary engine could later be licensed to other tools. An AI model does the reading.
The problem it solves
Almost nobody reads the terms they accept. Freelancers and small business owners sign vendor agreements, NDAs, and partnership contracts without a lawyer because lawyers are slow and costly. They do not need legal advice for every document. They need a quick warning: here is what you are agreeing to, and here is the part to question.
Who it suits
- Developers or no-code builders who can ship a browser extension
- Lawyers or paralegals who want a product built from their expertise
- Founders who sign many vendor and client contracts themselves
How it makes money
- Premium plan at ₹499 a month
- Annual plan at ₹4,999 a year
- Custom bulk plans for small businesses and startups
- Licensing the summary engine to other legal tools
How to test it this month
- 1Take twenty real documents, such as a freelance contract and a software terms page, test how an AI model summarises them, and mark every mistake.
- 2Build a bare extension that summarises the page you are on, then give it to ten freelancers to try on their next contract.
- 3Ask those ten whether they would pay ₹499 a month and which clause types they check first, before you build any paid plan.
What to watch out for
A wrong or missing summary can lead someone to sign something harmful. The tool must say clearly that it is not legal advice, and a lawyer should review how you word that. Contracts users paste often hold confidential or personal data, so decide what you store and for how long. Legal text varies widely, and summaries can miss context.
