A supplier sends an updated agreement with the message “only minor changes.” The layout looks familiar. One appendix has been replaced, a delivery condition now depends on a different event and a price is expressed per pack rather than per item. A sales or procurement team needs a clear comparison before it decides who should review the changes.
An AI amendment desk can organise the evidence and route questions to the right people while leaving interpretation and approval with the responsible reviewers. For European companies managing repeated supplier or customer agreements, the commercial opportunity is a faster, more traceable review process. This is a software design brief, not a substitute for legal advice on a particular contract.
Start with the pair of documents
Before generating a summary, the application must establish what it is comparing. A draft from last month, a signed agreement and a newly proposed amendment are different records. Ask the user to confirm the baseline and incoming revision, and preserve both originals.
Capture attachments and referenced schedules as part of the comparison set. An unchanged main document can point to a revised appendix. If an attachment is missing, show that gap explicitly. A summary of the available pages should not imply that the complete agreement was reviewed.
Record the sender, receipt time and the business relationship where appropriate, but keep a person responsible for associating the files with the right agreement. Similar filenames and email subjects are useful hints, not sufficient proof of document identity.
Extraction and interpretation are separate jobs
Mistral's OCR documentation describes extraction of text and document structure, including page and block information in supported configurations. This can help make scanned material searchable and preserve where text appeared. It does not establish the meaning of an amended commercial term.
Anthropic's citations documentation describes source-linked responses for supported document inputs. Such capabilities can support a review interface that points users back to evidence. A citation helps a reviewer inspect a claim; it does not prove the claim is a complete or correct interpretation.
Use deterministic comparison where it works well, especially for numbers, identifiers and exact text. Use language models to suggest groupings and explain candidate changes. The user should be able to distinguish a literal difference from an interpretation generated by the assistant.
Make the review screen carry the evidence
For each candidate change, show the relevant old passage, new passage and location in each source. Offer a concise description of the possible commercial effect, clearly presented as a review aid. Let the reviewer mark it as understood, needing clarification, irrelevant or requiring specialist review.
Moved text should not automatically count as a deleted obligation and a new obligation. Renumbered sections need a way to remain associated. When the system cannot confidently pair a clause, show the uncertain pairing so a person can correct it.
Keep exact values visible. A paraphrase such as “pricing updated” hides the detail a buyer needs to check. The interface should show the amount, currency, unit and any associated condition. Where a scanned value is uncertain, retain the page image nearby rather than displaying a precise-looking number without context.
Route a question to the person who can answer it
Different changes belong to different reviewers. Delivery scope may need operations input, a price-unit change may need procurement and an unfamiliar clause may need legal review. Let the organisation configure these categories and owners without pretending the model has authority to decide the final route in every case.
A review item should contain a question a colleague can answer. “Check section seven” is less useful than “Does the revised delivery trigger match the lead time we have approved?” Preserve the source passages and allow the reviewer to write a conclusion that remains attached to the document revision.
Do not transfer extracted terms directly into an ERP or obligation tracker merely because the comparison completed. That should be a separate, approved step with its own field mapping. The accepted operational record may require clarification beyond the wording in the draft.
Version history becomes the team's memory
Negotiations often contain several rounds of edits. Preserve which review comments apply to which revision, and show whether a later version resolved or reopened a question. A comment approved against one clause should not silently remain approved after that clause changes.
Avoid making the inbox the only source of history. A controlled workspace can connect files, reviewer decisions and requested clarifications while keeping access restricted to the relevant team. Establish retention, export and deletion rules with the organisation's responsible advisers and operating policy.
For multilingual agreements, preserve the original wording alongside any translated review aid. Do not assume two language versions are interchangeable or decide which governs. Those questions belong to the agreement and the qualified reviewers; the application should make the evidence easy to compare.
Give the pilot documents that can fool it
Test a clean PDF, a scanned copy, a replaced appendix and a document with moved paragraphs. Include a changed decimal, a switched unit and a condition removed from an otherwise similar sentence. Also include two identical versions so the tool has to produce an appropriately empty result.
Evaluate missed material changes, false alarms, source-link accuracy and reviewer time. Keep a distinction between extraction errors and reasoning errors so improvements address the right stage. A long list of findings can burden the team just as much as an incomplete list.
Ask reviewers whether they can explain a decision later using the stored evidence. That is a stronger outcome than a fluent summary with no stable connection to the reviewed files. The system should make review work easier to repeat and hand over.
A focused first release
Choose one document family and one review team. Agree the baseline selection process, supported file types, comparison categories, human approval and final destination. Include secure access, document export and an explicit way to suspend automated processing for unsuitable material.
Our guides to supplier document portals and software vendor assessment cover related workflow and procurement decisions. The same principle applies here: buy a process your people can operate and verify.
TuniCyberLabs builds custom document workflows and business applications. Discuss an amendment review pilot with a redacted document pair, your reviewer roles and the records you need after approval. That provides a practical basis for a scoped project and meaningful acceptance tests.
