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 tool switching and repeated setup while keeping one learner record. For language learners and workshop facilitators running practice programmes, convert learner goals, proficiency evidence, interests, licensed media and review history into facilitator-approved practice sets and progress records. The benefit is a testable hypothesis, measured through accepted practice sets per facilitator hour and retention of reviewed vocabulary; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect learner goals, proficiency evidence, interests, licensed media and review history, then follow this sequence: 1. Build personalized lessons from level, interests and goals. 2. Attach images and visuals to new words and concepts. 3. Deliver audio-only lessons for screen-free practice. 4. Prompt speaking practice out loud during lessons. 5. Schedule spaced repetition reviews at increasing intervals. Resolve uncertain cases with qualified reviewers, approve facilitator-approved practice sets and progress records, and measure accepted practice sets per facilitator hour and retention of reviewed vocabulary 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 target language pair and one proficiency framework; final placement, correction and certification decisions remain with qualified teachers. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve learner voice, source attribution, quotation accuracy and usage permissions. Facilitators and qualified teachers approve substantive changes and placement scope. One target language pair and one proficiency framework; final placement, correction and certification decisions remain with qualified teachers. 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 target language pair and one proficiency framework; final placement, correction and certification decisions remain with qualified teachers. Implement one approved input format, a bounded representative case set and the first two task modules: build personalized lessons from level, interests and goals; attach images and visuals to new words and concepts. 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
Learner-owned study material, authorized media and permitted research sources. Cloud asset storage, document and video import/export and learning management 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: Learner profile and goals, Editable lesson and practice preview, Facilitator review and delivery. Use a thumbnail gallery for learners and lesson sets, a large central editing canvas, and a right-hand panel for sources, constraints and comments. Let users compare lesson versions side by side. Display draft, changes requested and approved states. Provide a learner preview link with comments anchored to the relevant exercise. Make the task-specific outcome facilitator-approved practice sets and progress records visible beside its evidence, review state and value baseline.
