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
Keep one assumption-linked plan, model and forecast set instead of rebuilding it in separate tools. For founders, small business owners and advisors preparing structured plans, models and forecasts, convert raw idea notes, market inputs, cost data and ownership terms into a reviewer-approved plan, financial model and pitch package linked to named assumptions. The benefit is a testable hypothesis, measured through accepted plan versions per planning hour and forecast corrections after review; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect raw idea notes, market inputs, cost data and ownership terms, then follow this sequence: 1. Capture idea notes and score stated viability criteria. 2. Generate a structured business plan from approved inputs. 3. Build revenue, cost and cash-flow forecasts with editable drivers. 4. Attach market and competitor evidence to each claim. 5. Render a business model canvas from the same assumption set. Resolve uncertain cases with qualified reviewers, approve the reviewer-approved plan, financial model and pitch package linked to named assumptions, and measure accepted plan versions per planning hour and forecast corrections after review against a documented baseline.
How the AI works
Use AI to interpret permitted inputs, suggest structured mappings and generate candidate outputs for the stated task modules. Use deterministic code for arithmetic, schema validation, hard constraints and reproducible tests. Review source-linked explanations and uncertainty before accepting results. Financial arithmetic, legal and tax positions and investment claims remain reviewer responsibilities. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve founder voice, source attribution, quotation accuracy and usage permissions. Founders approve substantive changes and external sharing scope. One venture type and one planning template; financial arithmetic, legal and tax positions and investment claims remain reviewer responsibilities. Keep all consequential actions under authorized human control and do not fabricate missing inputs, permissions, professional judgments or market evidence.
What to build first
Pilot scope: One venture type and one planning template; financial arithmetic, legal and tax positions and investment claims remain reviewer responsibilities. Implement one approved input format, a bounded representative case set and the first two task modules: capture idea notes and score stated viability criteria; generate a structured business plan from approved inputs. Support the remaining modules with operator review: build revenue, cost and cash-flow forecasts with editable drivers; attach market and competitor evidence to each claim; render a business model canvas from the same assumption set. Include source references, corrections, basic organization access, approval states, export and value measurement. Use managed operator assistance for unresolved exceptions. The cost estimate covers this narrow prototype, not unrestricted multi-tenant scale, complex production integrations, specialist certification or physical operations.
What it can connect to
Founder-owned documents, spreadsheets and permitted research sources. Cloud document storage, spreadsheet import/export and presentation destinations. Start with file exchange and validate destination specifications before promising direct publishing. Start with authorized file exchange. Validate current provider access, usage rights and schema behavior before promising a connector.
The screens in detail
Primary screens: Assumption register and intake, Editable plan and model workspace, Review and export. Use a project gallery, a central editing canvas with plan sections and model tabs, and a right-hand panel for assumptions, sources and comments. Let users compare plan versions and model scenarios side by side. Display draft, changes requested and approved states. Provide a reviewer link with comments anchored to the relevant assumption or line item. Make the task-specific outcome reviewer-approved plan, financial model and pitch package linked to named assumptions visible beside its evidence, review state and value baseline.
