Contract Analysis AI in India

Legal and procurement teams reviewing vendor and commercial contracts at volume are increasingly using large language models to speed up the first pass — flagging unusual clauses, extracting key terms, and summarising long documents before a lawyer reads them properly. unoblox runs that work through one rupee-billed API, and it's worth saying plainly upfront: this is a drafting and triage aid, not legal advice, and it doesn't replace a qualified lawyer's review.

What AI contract review can (and can't) do

An LLM can extract structured terms (parties, dates, payment terms, termination clauses), flag clauses that look unusual compared to a template you provide, and summarise a long contract into a shorter brief. It cannot certify that a contract is legally sound, and it shouldn't be the last check before signature — human legal review stays in the loop for anything that matters.

A practical two-pass workflow

1. Run every incoming contract through a cheap, fast model to extract key terms and flag sections that look unusual
2. Send flagged sections (or the full contract, for higher-stakes deals) to a stronger reasoning model for clause-by-clause commentary
3. A human lawyer reviews the flagged output and the model's summary before anything is signed

Billing, and a clear disclaimer

Every model is priced per million tokens in rupees, with one monthly GST invoice and no international card needed. Separately, and importantly: nothing produced through unoblox is legal advice, and no output should be treated as a substitute for a qualified lawyer reviewing the actual document before you sign anything.

Frequently asked questions

Is this a replacement for a lawyer? No. It speeds up the first pass — extraction, flagging, and summarisation — but a human lawyer should review anything before it's relied on.

Can it read scanned contract PDFs? Only a vision-capable model can process an image directly — qwen/qwen3.8-27b supports vision, though you should verify accuracy on your own scan quality before relying on it.

Which model should run on every contract? A cheap, fast model like deepseek-ai/deepseek-v4-flash for the first pass, reserving a stronger model for flagged or high-value contracts.

Is there a free way to test this? Yes, qwen/qwen3-1.7b is free (₹0), enough to validate your extraction prompts.

Is pricing genuinely in rupees? Yes — every model is priced and billed in rupees per million tokens, invoiced monthly with GST.

Does unoblox certify contracts as compliant with Indian law? No — unoblox provides model access, not legal certification. Compliance and legal sign-off remain your responsibility.
