AI app for creatives · no coding needed
Multilingual subtitle production and review portal
Reduce subtitle production cycles while keeping timing, tone and review state in one owned workspace.
Made for: Video teams and creators producing subtitled or dubbed content in several languages
What it does for you
The problem
Subtitle work is split across transcription, editing, translation, dubbing and social resizing tools, so timing, tone and review state are lost between them.
What it gives you
Reviewer-approved subtitle and dub packages linked to the source video

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 subtitle production cycles while keeping timing, tone and review state in one owned workspace. For video teams and creators producing subtitled or dubbed content in several languages, convert uploaded video or audio, source language settings, tone instructions and platform targets into reviewer-approved subtitle and dub packages linked to the source video. The benefit is a testable hypothesis, measured through accepted subtitle packages per production hour and corrections after publishing; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect uploaded video or audio, source language settings, tone instructions and platform targets, then follow this sequence: 1. Transcribe speech from uploaded video or audio. 2. Edit and fine-tune generated subtitles on a timeline. 3. Flag uncertain words and show a review count until cleared. 4. Translate subtitles while keeping original timing. 5. Generate synthetic voice dub tracks in multiple languages. Resolve uncertain cases with qualified reviewers, approve reviewer-approved subtitle and dub packages linked to the source video, and measure accepted subtitle packages per production hour and corrections after publishing 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 timing arithmetic, schema validation, hard constraints and reproducible tests. Review source-linked explanations and uncertainty before accepting results. Final language, timing and tone checks remain editorial. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve speaker voice, source attribution, quotation accuracy and usage permissions. Creators approve substantive changes and publication scope. One source language and two target languages; final language, timing and tone checks remain editorial. 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 source language and two target languages; final language, timing and tone checks remain editorial. Implement one approved input format, a bounded representative case set and the first three task modules: transcribe speech from uploaded video or audio; edit and fine-tune generated subtitles on a timeline; flag uncertain words and show a review count until cleared. Support translation and dubbing 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
Creator-owned video files, authorized interviews and permitted research sources. Cloud asset storage, design-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: Project intake and language setup, Editable subtitle and dub preview, Client proof and delivery. Use a thumbnail gallery for projects, a large central video canvas with a synchronized subtitle timeline, and a right-hand panel for languages, tone instructions, styles 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 reviewer-approved subtitle and dub packages linked to the source video visible beside its evidence, review state and value baseline.
