Questions
Do I need to know how to code?
No. You copy and paste the prompts on this page into ChatGPT or Claude, and the AI does the building. When it asks you something, you answer in your own words.
What does it cost?
The quick version, the app pack and the step-by-step instructions are for members: you pay the membership price, not a price per app (see the plans). Building the full app uses your own ChatGPT or Claude subscription. Putting it online is often cheap or no cost at the start, and your AI tells you before anything costs money.
How long does it take?
The quick version: about two minutes. The real app: an afternoon for a first version you can use, longer if you want every feature.
Can I change it to fit my business?
Yes. Tell your AI what to change in plain words, like “add a column for the price” or “use our logo and colours”. Or have Nexibeo build and customise it for you.
More detailsHow the AI works, safeguards and what to build first
For commercial lawyers reviewing negotiated drafts, turn contract versions and clause taxonomy into annotated contract comparison. Address the recurring problem: meaningful changes are buried in formatting and renumbering. The pilot measures useful change detection and false alarms against the buyer's current method, before the larger build.
Define comparison fields, upload source versions or offers, extract candidate values, normalize only agreed units, inspect differences, resolve questions with reviewers, and export an evidence-linked comparison. Start with contract versions and clause taxonomy and finish with annotated contract comparison.
How the AI works
Align document sections and extract proposed comparable fields. Deterministic checks handle units and arithmetic. Preserve original wording and label assumptions. Professional reviewers assess the meaning and significance of differences.
Safeguards
Preserve matter confidentiality, access boundaries and original evidence. Qualified professionals review legal interpretations and final client documents. Validate source access and reviewer availability during the pilot. Maintain customer-level access, data deletion controls and a record of final approvals.
What to build first
Begin with commercial lawyers reviewing negotiated drafts and one recurring use case. Build the first two modules: align clauses; detect moved sections. Provide operator assistance for the third module: isolate wording changes. Deliver annotated contract comparison through a manual review queue. Perform other necessary full-scope functions manually during the pilot. Include all applicable access, accuracy and professional-review controls from the start.
What it can connect to
Authorized matter files, firm templates and approved legal knowledge collections. Document repositories, procurement or contract records and spreadsheet exports. Preserve originals and avoid writing back interpretations without approval. These are candidate integration categories, not verified supported connectors.
The screens in detail
Use a side-by-side matrix with the same fields for every document or option. Clicking a value reveals its original passage. Highlight missing, different and uncertain items separately. Provide a clarification queue and reviewer annotations before exporting a decision pack. In this product, the first view is draft alignment, followed by clause changes and reviewer notes.
