AI app for product development · no coding needed
Product specification and signal workbench
Reduce spec drafting and rework cycles while keeping the product team's decisions in one owned workspace.
Made for: Product managers and small product teams turning rough ideas into buildable specs

What it does for you
The problem
Rough product ideas are scattered across documents, repos and data sources, so specs, wireframes and plans are rebuilt by hand and drift out of date.
What it gives you
Reviewed product specifications, wireframes, user flows and technical plans linked to their sources
What you give it

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
Reduce spec drafting and rework cycles while keeping the product team's decisions in one owned workspace. For product managers and small product teams turning rough ideas into buildable specs, convert brief ideas, repo contents, feedback and monitored signals into reviewed product specifications, wireframes, user flows and technical plans linked to their sources. The benefit is a testable hypothesis, measured through accepted specs per product hour and rework after development starts; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect brief ideas, repository contents, feedback and monitored signals, then follow this sequence: 1. Turn brief ideas or prompts into structured product specifications. 2. Produce product requirement documents from project details. 3. Generate wireframes for feature designs. 4. Generate user flows as part of the specification output. 5. Generate technical specifications for development. Resolve uncertain cases with qualified reviewers, approve reviewed product specifications, wireframes, user flows and technical plans linked to their sources, and measure accepted specs per product hour and rework after development starts 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. One approved repository scope and template set; final product and technical decisions remain with the product team. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve product intent, source attribution, quotation accuracy and usage permissions. The product team approves substantive changes and release scope. One approved repository scope and template set; final product and technical decisions remain with the product team. 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 approved repository scope and template set; final product and technical decisions remain with the product team. Implement one approved input format, a bounded representative case set and the first three task modules: turn brief ideas or prompts into structured product specifications; produce product requirement documents from project details; generate wireframes for feature designs. Support the remaining modules with operator review. 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
Customer-owned repositories, authorized feedback sources and permitted data platforms. Cloud document storage, AI coding tools and IDEs, project management and communication platforms, and data platforms. 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: Idea intake and sources, Editable specification workspace, Review and handoff. Use a thumbnail gallery for projects, a large central editing canvas, and a right-hand panel for sources, signals, comments and constraints. Let users compare spec versions side by side. Display draft, changes requested and approved states. Provide a client preview link with comments anchored to the relevant section. Make the task-specific outcome reviewed product specifications, wireframes, user flows and technical plans linked to their sources visible beside its evidence, review state and value baseline.
