AI does the heavy lifting, people stay in charge

Use AI to interpret permitted inputs, suggest structured mappings and generate candidate translations for the stated task modules. Use deterministic code for key validation, placeholder checks, schema validation, hard constraints and reproducible tests. Review source-linked explanations and uncertainty before accepting results. Final terminology and brand-voice decisions remain with the localization team. A model suggestion is never a verified fact, professional decision or authorization to release.

What your team sees

Primary screens: Project and locale setup, Editable translation workspace, Review and release. Use a locale list for projects, a large central string table with source and target columns, and a right-hand panel for glossary, tone, context and comments. Let users compare locales and versions side by side. Display draft, changes requested and approved states. Provide a release preview link with comments anchored to the relevant string. Make the task-specific outcome reviewer-approved localized content linked to release builds visible beside its evidence, review state and value baseline.

Accounts and administration

Project ownership, locale versions, reviewer 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

App code repositories, localization files, CI/CD pipelines and App Store metadata. 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.

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 product and localization teams shipping app and software content in multiple languages use it to solve "app and software content is translated across several disconnected tools, so terminology, brand voice and review state drift between locales and releases"?
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 localized strings per localization hour and post-release terminology corrections.
4. Measure, then decide. Track accepted localized strings per localization hour and post-release terminology corrections; 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 app codebase, a fixed set of target locales and one glossary; final terminology and brand-voice checks remain with the localization team. Implement one approved input format, a bounded representative case set and the first three task modules: translate app strings and content into multiple languages with AI; enforce glossary and terminology mappings across strings; apply tone and brand voice profiles per locale. Support the remaining modules with operator review: embed localization through APIs, CLI tools, CI/CD, webhooks or MCP; validate missing keys, file structures, placeholders and untranslated content before deployment. 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 reviewer-approved localized content linked to release builds. Retain the explicit scope boundary: One app codebase, a fixed set of target locales and one glossary; final terminology and brand-voice checks remain with the localization team.

What the build depends on. Asset upload and preview, asynchronous translation jobs, editable version history, reviewer access and tested export formats. High-fidelity production requires specialist localization QA. Obtain representative authorized cases, baseline measurements, qualified reviewers and a buyer-side decision owner. Specific limitation: One app codebase, a fixed set of target locales and one glossary; final terminology and brand-voice checks remain with the localization team.

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

A rough indication of monthly hosting and AI model costs once it is live, not tested. Real costs depend on usage, file sizes and the models chosen.

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 app and locale set. Offer a monthly production allowance after repeat demand. Quote complex integrations or specialist locale work separately. These are test prices, not market benchmarks. Package the initial sale as one bounded reviewer-approved localized content linked to release builds. 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 fragmented localization work while keeping terminology and brand voice consistent. Demonstrate a concrete reviewer-approved localized content linked to release builds using the buyer's approved example and show the baseline, corrections and actual delivery effort.

Where to find buyers

Product and localization teams shipping app and software content in multiple languages professional communities; specialist consultants serving this buyer; permissioned partner introductions; practical demonstrations at relevant trade or practitioner events.

Lead magnet

A reviewed sample reviewer-approved localized content linked to release builds from a small authorized input set, with a transparent calculation of accepted localized strings per localization hour and post-release terminology corrections and no promised savings.

The first 30 days

1. Week 1: interview five product and localization teams shipping app and software content in multiple languages and inspect a recent example of app and software content translated across several disconnected tools, so terminology, brand voice and review state drift between locales and releases.
2. Week 2: prepare a consented or synthetic demonstration of the three task modules.
3. Week 3: seek one bounded paid pilot with agreed baseline and acceptance criteria.
4. Week 4: measure accepted localized strings per localization hour and post-release terminology corrections, 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 localized strings per localization hour and post-release terminology corrections. 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 localized strings per localization hour and post-release terminology corrections; accepted-output rate; material error rate; reviewer correction time; actual repeat purchase.

Retention and expansion

Repeat the workflow when the buyer again needs reviewer-approved localized content linked to release builds. 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 glossaries, tone profiles, code-context rules and review examples, together with reliable delivery for a narrow software niche. Build a permissioned library of representative task cases, reviewer corrections and verified operating constraints for product and localization teams shipping app and software content in multiple languages. Repeatable delivery and useful integrations matter more than access to a base model.

Alternatives and positioning

LocIn AI, Lingo.dev v1, Xpolyglot, Prismy and Tolgee. Compare this product with the buyer's present method on accepted localized strings per localization hour and post-release terminology corrections. Offer a bounded paid workflow instead of claiming broad autonomous expertise. Market uniqueness and competitor coverage are not verified.

Main delivery costs

Translation attempts, model usage, storage, reviewer hours, client revision rounds and licensed source assets. Additional initial validation requires representative authorized sample preparation, buyer interviews, buyer-side evaluation and bounded validation of reviewer-approved localized content linked to release builds. Track cost per accepted output, including correction work, unsuccessful cases and support.

Preserve brand voice, source attribution, terminology accuracy and usage permissions. Localization teams approve substantive changes and release scope. One app codebase, a fixed set of target locales and one glossary; final terminology and brand-voice checks remain with the localization team. Keep all consequential actions under authorized human control and do not fabricate missing inputs, permissions, professional judgments or market evidence.
