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 scheduling arithmetic, schema validation, hard constraints and reproducible tests. Review source-linked explanations and uncertainty before accepting results. One fixed language pair and licensed source set; final meaning, translation and curriculum checks remain with the tutor. A model suggestion is never a verified fact, professional decision or authorization to act.

What your team sees

Primary screens: Material intake and word review, Practice session, Tutor or facilitator dashboard. Use a deck gallery for sets, a large central review canvas for the current card, and a right-hand panel for source sentence, explanation and scheduling state. Let users compare a generated card with the source text side by side. Display draft, changes requested and approved states. Provide a shared practice link with comments anchored to the relevant card. Make the task-specific outcome reviewed flashcard sets and spaced-repetition schedules visible beside its evidence, review state and value baseline.

Accounts and administration

Learner and group ownership, deck versions, tutor comments, approval states, usage allowances, review 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

Learner-owned documents, authorized reading material and permitted research sources. Cloud file storage, document 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.

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 language learners, tutors and training teams running vocabulary practice use it to solve "vocabulary practice is split across several subscriptions, so learners lose their own word history and tutors cannot see what was actually reviewed"?
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: Reviewed words retained at delayed test and tutor hours per accepted set.
4. Measure, then decide. Track reviewed words retained at delayed test and tutor hours per accepted set; 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 fixed language pair and licensed source set; final meaning, translation and curriculum checks remain with the tutor. Implement one approved input format, a bounded representative case set and the first two task modules: generate flashcards from supplied learning material or learner progress; schedule reviews with spaced repetition. Support the remaining modules with operator review: extract vocabulary and source sentences; generate meanings, usage notes, examples, collocations and pronunciation. 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 languages and case volume only after new evaluation cases pass. Build reusable customer configurations and recurring value reports around reviewed flashcard sets and spaced-repetition schedules. Retain the explicit scope boundary: One fixed language pair and licensed source set; final meaning, translation and curriculum checks remain with the tutor.

What the build depends on. Material upload and preview, asynchronous generation jobs, editable version history, reviewer access and tested export formats. High-fidelity curriculum work requires specialist language QA. Obtain representative authorized cases, baseline measurements, qualified reviewers and a buyer-side decision owner. Specific limitation: One fixed language pair and licensed source set; final meaning, translation and curriculum checks remain with the tutor.

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 learner group or deck package. Offer a monthly practice allowance after repeat demand. Quote specialist curriculum or certification work separately. These are test prices, not market benchmarks. Package the initial sale as one bounded reviewed flashcard set and schedule. 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 the number of separate vocabulary tools a learner or tutor rents while keeping one owned record of words, reviews and progress. Demonstrate a concrete reviewed flashcard set and schedule using the buyer's approved example and show the baseline, corrections and actual delivery effort.

Where to find buyers

Language learners, tutors and training teams professional communities; specialist consultants serving this buyer; permissioned partner introductions; practical demonstrations at relevant trade or practitioner events.

Lead magnet

A reviewed sample flashcard set and schedule from a small authorized input set, with a transparent calculation of reviewed words retained at delayed test and tutor hours per accepted set and no promised savings.

The first 30 days

1. Week 1: interview five language learners, tutors and training teams running vocabulary practice and inspect a recent example of vocabulary practice split across several subscriptions, so learners lose their own word history and tutors cannot see what was actually reviewed.
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 reviewed words retained at delayed test and tutor hours per accepted set, 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: Reviewed words retained at delayed test and tutor hours per accepted set. 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

Reviewed words retained at delayed test and tutor hours per accepted set; accepted-output rate; material error rate; reviewer correction time; actual repeat purchase.

Retention and expansion

Repeat the workflow when the buyer again needs reviewed flashcard sets and spaced-repetition schedules. 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 word lists, review examples and tutor corrections, together with reliable delivery for a narrow learning niche. Build a permissioned library of representative task cases, reviewer corrections and verified operating constraints for language learners, tutors and training teams running vocabulary practice. Repeatable delivery and useful integrations matter more than access to a base model.

Alternatives and positioning

WordFlippin, LingQuiz, Zingle, Flash, KardsAI, Essential Vocabulary and Cogent, plus tutors, generic flashcard apps and manual word lists. Compare this product with the buyer's present method on reviewed words retained at delayed test and tutor hours per accepted set. Offer a bounded paid workflow instead of claiming broad autonomous expertise. Market uniqueness and competitor coverage are not verified.

Main delivery costs

Generation attempts, speech and image processing, storage, reviewer hours, learner revision rounds and licensed source material. Additional initial validation requires representative authorized sample preparation, buyer interviews, buyer-side evaluation and bounded validation of reviewed flashcard sets and spaced-repetition schedules. Track cost per accepted output, including correction work, unsuccessful cases and support.

Preserve learner voice, source attribution, translation accuracy and usage permissions. Tutors approve substantive changes and curriculum scope. One fixed language pair and licensed source set; final meaning, translation and curriculum checks remain with the tutor. Keep all consequential actions under authorized human control and do not fabricate missing inputs, permissions, professional judgments or market evidence.
