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 small specialist trade contractors, turn approved estimates, measurements and service terms into reviewed contractor proposal. Address the recurring problem: quotes look inconsistent and fail to explain scope clearly. The pilot measures preparation time and scope clarification requests against the buyer's current method, before the larger build.
Collect a structured brief and source material, identify unanswered questions, approve an outline, generate a draft, verify claims, gather reviewer edits, approve a final version and export the agreed formats. Start with approved estimates, measurements and service terms and finish with reviewed contractor proposal.
How the AI works
Extract and organize information, propose structure, draft prose and adapt approved content to audiences. Attach evidence to factual claims. Keep names, dates, amounts and quoted wording linked to their source. Editors resolve ambiguity and approve publication.
Safeguards
Verify property facts and scope assumptions. Clearly label visual alterations. Professional reviewers retain responsibility for contracts, engineering and legal interpretations. 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 small specialist trade contractors and one recurring use case. Build the first two modules: structure work scope; include approved quantities. Provide operator assistance for the third module: separate options. Deliver reviewed contractor proposal 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
Property records, construction documents, project photos and supplier quotes. Document storage, word processor export, content management systems and approved publishing channels. Pilot with uploads and downloadable drafts before adding write integrations. These are candidate integration categories, not verified supported connectors.
The screens in detail
Use a project list and editorial calendar beside a document editor. Keep original material and supporting passages in a collapsible side panel. Show outline, draft, review and approved stages. Provide tracked edits, comments, version comparisons and an export preview that reflects the final delivery format. In this product, the first view is job brief, followed by scope builder and proposal preview.
