Free and paid tiers use different AI engines. Here's what that means in practice.
Free · Standard engine
Fast, reliable analysis.
Identifies the 4–6 most significant clauses. Flags obvious risks with plain English explanations and clear recommendations. Works on contracts up to ~6,000 words. Good for a confident first read of any contract.
Pro & Business · Advanced engine
Substantively deeper.
Catches subtler issues the standard engine misses. References specific UK statutes where relevant — UCTA 1977, Late Payment Regulations, Consumer Rights Act 2015. Handles longer contracts. More thorough recommendations with specific alternative language to propose.
Neither tier is a substitute for a qualified solicitor on high-stakes contracts. ContractChecker is an AI tool, not a law firm.
Business plan · example
Don't just spot the bad clause — rewrite it.
Original clause
"The Supplier shall indemnify and hold harmless the Client from any and all claims, losses, damages, liabilities and expenses arising out of or relating to the Supplier's performance under this Agreement."
Suggested rewrite
"The Supplier's total liability shall be capped at the fees paid in the 12 months preceding the claim. The Supplier shall indemnify the Client only for direct losses caused by the Supplier's gross negligence or wilful misconduct."
What changed: Unlimited liability has become a 12-month fee cap. The indemnity now only applies to gross negligence — not any and all claims. A fairer, standard commercial position.
