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 manual file handling while keeping the buyer's audio and workflow in one owned app. For producers, DJs, audio editors and media teams working with recorded music and dialogue, convert licensed audio tracks, dialogue recordings and session settings into reviewed stem sets and remix versions linked to the source track. The benefit is a testable hypothesis, measured through accepted stem sets per production hour and corrections after mix approval; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect licensed audio tracks, dialogue recordings and session settings, then follow this sequence: 1. Separate any audio track into vocals, drums, bass and other instruments. 2. Isolate or mute specific vocals and instruments. 3. Build remixes and mashups from existing tracks. Resolve uncertain cases with qualified reviewers, approve reviewed stem sets and remix versions linked to the source track, and measure accepted stem sets per production hour and corrections after mix approval 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 fixed sample rate and licensed source set; final mix and rights checks remain human. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve source attribution, rights permissions and mix intent. Rights holders and named reviewers approve substantive changes and publication scope. One fixed sample rate and licensed source set; final mix and rights checks remain human. 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 fixed sample rate and licensed source set; final mix and rights checks remain human. Implement one approved input format, a bounded representative case set and the first two task modules: separate any audio track into vocals, drums, bass and other instruments; isolate or mute specific vocals and instruments. Support the third module with operator review: build remixes and mashups from existing tracks. 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
Buyer-owned audio files, authorized dialogue recordings and permitted music sources. Cloud asset storage, DAW file import/export and publishing 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: Audio intake and rights check, Stem and remix editing canvas, Client review and delivery. Use a track gallery for projects, a large central waveform and stem editor, and a right-hand panel for stems, key, tempo, lyrics and comments. Let users compare versions side by side. Display draft, changes requested and approved states. Provide a client preview link with comments anchored to the relevant timecode. Make the task-specific outcome reviewed stem sets and remix versions linked to the source track visible beside its evidence, review state and value baseline.
