AI does the heavy lifting, people stay in charge

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 voice set and language list; final pronunciation and meaning checks remain editorial. A model suggestion is never a verified fact, professional decision or authorization to act.

What your team sees

Primary screens: Script and source intake, Editable narration preview, Client proof and delivery. Use a thumbnail gallery for projects, a large central editing canvas, and a right-hand panel for references, constraints 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 audio segment. Make the task-specific outcome editor-approved narration masters linked to their source text visible beside its evidence, review state and value baseline.

Accounts and administration

Project ownership, asset versions, client comments, approval states, usage allowances, revision limits, download history and a rights record for supplied material. Add organization access boundaries, named reviewers, usage caps, data retention controls, export logs and explicit approval for external actions.

Integrations and data access

Author-owned scripts, authorized brand voice samples and permitted research sources. Cloud asset storage, document 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.

We build with our own AI software development factory, so most implementations take days to a few weeks of creation time, not months. You see working software at every step, and exact timing depends on availability.

Why we start with an MVP

An MVP, or minimum viable product, is the smallest version that your users can actually work with. It is not a cheap version of the full solution. It is a test, built to answer the questions that decide whether the rest is worth building.

1. Pick the riskiest assumption. Here: will marketing and content teams producing narrated audio from written material use it to solve "narrated audio is produced across several rented tools, so scripts, voice settings, approvals and exports are scattered and hard to reuse"?
2. Build only what tests it. One team, one use case, a few core modules. People do the rest by hand for now.
3. Run a paid pilot. Agree quality and outcome thresholds before the pilot using this measure: Accepted narration minutes per production hour and corrections after approval.
4. Measure, then decide. Track accepted narration minutes per production hour and corrections after approval; accepted-output rate; material error rate; reviewer correction time; actual repeat purchase. Then expand, change course or stop, with evidence instead of opinions.

MVP scope for this solution. Pilot scope: One approved voice set and language list; final pronunciation and meaning checks remain editorial. Implement one approved input format, a bounded representative case set and the first two task modules: import scripts from text, PDF and document formats; convert written text into spoken audio. Support the remaining modules with operator review: select voices, adjust delivery, clone a brand voice, build multi-speaker projects, apply SSML, export MP3 and WAV. 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.

After the MVP. Once paid pilots prove usefulness, automate repeatable reviewed steps and add one verified source integration. Expand supported inputs and case volume only after new evaluation cases pass. Build reusable customer configurations and recurring value reports around editor-approved narration masters linked to their source text. Retain the explicit scope boundary: One approved voice set and language list; final pronunciation and meaning checks remain editorial.

What the build depends on. Asset upload and preview, asynchronous generation jobs, editable version history, reviewer access and tested export formats. High-fidelity production requires specialist audio QA. Obtain representative authorized cases, baseline measurements, qualified reviewers and a buyer-side decision owner. Specific limitation: One approved voice set and language list; final pronunciation and meaning checks remain editorial.

A planning range to start the conversation, not a quote. You pay per phase, so you can stop after the MVP.

Running costs per month

Selling it to your own clients: the go-to-market playbook

Pricing to test

Test a USD 300-1,500 fixed pilot for one defined narration package. Offer a monthly production allowance after repeat demand. Quote complex voice cloning or multi-language projects separately. These are test prices, not market benchmarks. Package the initial sale as one bounded editor-approved narration master. Recurring fees must specify volume, review depth and integration support. For exchanges, test a disclosed coordination or successful-service fee rather than holding customer funds. Reprice only after measuring real delivery labor; platform-build cost is separate from a commercial pilot fee.

Message to test

Reduce narration production cycles while keeping the writer's meaning and the brand voice. Demonstrate a concrete editor-approved narration master linked to its source text using the buyer's approved example and show the baseline, corrections and actual delivery effort.

Where to find buyers

Marketing and content teams producing narrated audio from written material professional communities; specialist consultants serving this buyer; permissioned partner introductions; practical demonstrations at relevant trade or practitioner events.

Lead magnet

A reviewed sample editor-approved narration master linked to its source text from a small authorized input set, with a transparent calculation of accepted narration minutes per production hour and corrections after approval and no promised savings.

The first 30 days

1. Week 1: interview five marketing and content teams producing narrated audio from written material and inspect a recent example of narrated audio produced across several rented tools, so scripts, voice settings, approvals and exports are scattered and hard to reuse.
2. Week 2: prepare a consented or synthetic demonstration of the stated task modules.
3. Week 3: seek one bounded paid pilot with agreed baseline and acceptance criteria.
4. Week 4: measure accepted narration minutes per production hour and corrections after approval, reviewer effort and repeat-purchase interest. This is a demand-validation plan, not a thirty-day full-product delivery promise.

Paid pilot

Agree quality and outcome thresholds before the pilot using this measure: Accepted narration minutes per production hour and corrections after approval. Continue only if the buyer accepts the actual output, the intended job outcome improves without unacceptable errors, and measured delivery cost fits willingness to pay. Revise or stop if access is unavailable, qualified review cannot be provided, or apparent savings disappear after corrections and support. Use held-out cases when comparing model quality; use a properly reviewed comparison design before making causal claims. Record missing cases and negative results alongside successful outputs.

Success metrics

Accepted narration minutes per production hour and corrections after approval; accepted-output rate; material error rate; reviewer correction time; actual repeat purchase.

Retention and expansion

Repeat the workflow when the buyer again needs editor-approved narration masters linked to their source text. Retain permissioned settings and reviewed examples, report realized value honestly, and sell increased volume or adjacent approved workflows only after contribution margin and quality remain acceptable.

Why clients would pick it

A reusable library of approved voices, pronunciation rules and review examples, together with reliable delivery for a narrow content niche. Build a permissioned library of representative task cases, reviewer corrections and verified operating constraints for marketing and content teams producing narrated audio from written material. Repeatable delivery and useful integrations matter more than access to a base model.

Alternatives and positioning

Listnr, Narration Box, Play.ht, Murf.ai, WellSaid Labs, SpeechEasy, DupDub, Speechify, NaturalReader and TTS-Voice-Wizard. Compare this product with the buyer's present method on accepted narration minutes per production hour and corrections after approval. Offer a bounded paid workflow instead of claiming broad autonomous expertise. Market uniqueness and competitor coverage are not verified.

Main delivery costs

Generation attempts, audio processing, storage, reviewer hours, client revision rounds and licensed voice assets. Additional initial validation requires representative authorized sample preparation, buyer interviews, buyer-side evaluation and bounded validation of editor-approved narration masters linked to their source text. Track cost per accepted output, including correction work, unsuccessful cases and support.

Preserve author voice, source attribution, quotation accuracy and usage permissions. Authors approve substantive changes and publication scope. One approved voice set and language list; final pronunciation and meaning checks remain editorial. Keep all consequential actions under authorized human control and do not fabricate missing inputs, permissions, professional judgments or market evidence.
