Synthetic usability evidence workbench

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 designers and UX researchers running quick usability checks on designs and prototypes use it to solve "live usability tests are slow and costly, so teams ship designs with unverified usability issues"?
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 usability findings per design iteration and reduction in unaddressed issues after review.
4. Measure, then decide. Track accepted usability findings per design iteration and reduction in unaddressed issues after review; 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 design tool integration (Figma), one prototype format and one live URL type; synthetic findings remain advisory and require human review. Implement one approved input format, a bounded representative case set and the first two task modules: import Figma designs, prototypes and live URLs; generate target user personas from transcripts or text descriptions. Support the remaining modules with operator review: run AI-simulated usability tests with synthetic users; simulate think-aloud verbalizations; capture transcripts and recordings; predict attention; detect cognitive load; validate user flows; run iterative cycles; compare design variations; surface accessibility issues; consolidate findings; generate recommendations; support multi-language sessions. 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 reviewed usability findings linked to design evidence. Retain the explicit scope boundary: One design tool integration (Figma), one prototype format and one live URL type; synthetic findings remain advisory and require human review.

What the build depends on. Design upload and preview, asynchronous generation jobs, editable version history, reviewer access and tested export formats. High-fidelity usability requires specialist review. Obtain representative authorized cases, baseline measurements, qualified reviewers and a buyer-side decision owner. Specific limitation: One design tool integration (Figma), one prototype format and one live URL type; synthetic findings remain advisory and require human review.

Pricing to test

Test a USD 300-1,500 fixed pilot for one defined design package. Offer a monthly production allowance after repeat demand. Quote complex multi-language or accessibility certification separately. These are test prices, not market benchmarks. Package the initial sale as one bounded reviewed usability findings report. 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 reliance on live participants for early usability checks while keeping evidence and human review. Demonstrate a concrete reviewed usability findings report using the buyer's approved example and show the baseline, corrections and actual delivery effort.

Where to find buyers

Product designers and UX researchers professional communities; specialist consultants serving this buyer; permissioned partner introductions; practical demonstrations at relevant trade or practitioner events.

Lead magnet

A reviewed sample usability findings report from a small authorized design set, with a transparent calculation of accepted usability findings per design iteration and reduction in unaddressed issues after review and no promised savings.

The first 30 days

1. Week 1: interview five product designers and UX researchers running quick usability checks on designs and prototypes and inspect a recent example of live usability tests being slow and costly, so teams ship designs with unverified usability issues.
2. Week 2: prepare a consented or synthetic demonstration of the task modules.
3. Week 3: seek one bounded paid pilot with agreed baseline and acceptance criteria.
4. Week 4: measure accepted usability findings per design iteration and reduction in unaddressed issues after review, 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 usability findings per design iteration and reduction in unaddressed issues after review. 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 usability findings per design iteration and reduction in unaddressed issues after review; accepted-output rate; material error rate; reviewer correction time; actual repeat purchase.

Retention and expansion

Repeat the workflow when the buyer again needs reviewed usability findings linked to design evidence. 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 usability patterns, design constraints and review examples, together with reliable delivery for a narrow product design niche. Build a permissioned library of representative task cases, reviewer corrections and verified operating constraints for product designers and UX researchers running quick usability checks on designs and prototypes. Repeatable delivery and useful integrations matter more than access to a base model.

Alternatives and positioning

Snap, Uxia, Userology AI and Visual Usability Checker, plus live usability testing services and generic design review tools. Compare this product with the buyer's present method on accepted usability findings per design iteration and reduction in unaddressed issues after review. Offer a bounded paid workflow instead of claiming broad autonomous expertise. Market uniqueness and competitor coverage are not verified.

Main delivery costs

Synthetic session generation, 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 reviewed usability findings linked to design evidence. Track cost per accepted output, including correction work, unsuccessful cases and support.
