As of 13 August 2026, AI can only partly compare two employment contracts.

What to actually do

1. Hand it to a person

   The route this page recommends

   A person who owns the outcome does this end to end, worth it when the failure is dear.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, chat-fluent skill, and roughly 1 hour until you can act on the result.

   How to actually do it

   1. Open both employment contracts and save copies with identifying details such as your address, National Insurance number and bank details removed where they are not needed.
   2. Label the files Contract A and Contract B, then check that each file contains the complete agreement, including schedules, policies and referenced appendices.
   3. Paste the prompt and both contracts into a chatbot that accepts document uploads, or paste the text under the two labelled headings if uploads are unavailable.
   4. Ask the chatbot to produce the comparison table and keep the original contracts open while it works.
   5. Compare every quoted clause and page reference in the response against the two contracts, correcting any missing, misquoted or misread wording.
   6. Send the verified list of important differences and solicitor-review points to a UK employment solicitor before signing if the contract contains restrictive covenants, disputed pay or hours, unusual deductions, dismissal concerns or another serious issue.

   Prompt

   Compare the two employment contracts below for a UK employee. This is not professional advice. Do not give legal advice or decide whether either contract is fair or enforceable. Extract and compare only what the documents say.
   
   Create a table with these columns: topic, Contract A wording, Contract B wording, difference, practical question to ask. Cover pay, working hours, place of work, probation, holiday, sick pay, notice, termination, pension, benefits, bonus, expenses, confidentiality, intellectual property, restrictive covenants, holiday during notice, deductions, collective agreements, and any unusual or missing terms. Quote the relevant wording or give the page and section reference for every material difference. Mark a topic as "not found" rather than guessing. Separate clear textual differences from points whose meaning is uncertain. Finish with:
   1. five questions I should ask the employer;
   2. a list of clauses that a UK employment solicitor should review, with a short reason for each;
   3. a checklist of factual details I need to confirm before signing.
   
   Use plain English, invent nothing, and do not rely on current law or assumptions outside these documents. Do not include personal data that is not needed for the comparison.
   
   Contract A:
   [PASTE CONTRACT A HERE]
   
   Contract B:
   [PASTE CONTRACT B HERE]

   Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.
