Inside your business, or as part of your offer to clients

Reduce hand-coded interface work while keeping every change reviewable and reversible.

1. Edit the real running app interface instead of a static mockup.
2. Adjust elements directly in the interface with an edit control.
3. Update text, colors, sizes and component styling instantly without writing code prompts.
4. Assist broader or prompted changes with AI alongside manual controls.
5. Reuse components already defined in the codebase.
6. Respect the design tokens set up in the codebase.
7. Work with real live data rather than placeholder content.
8. Apply custom Tailwind CSS classes for advanced styling.
9. Run changes in isolated sandboxed copies so production data is not touched.
10. Generate a preview link for each change so reviewers can test it before merging.
11. Drag one variant into another to combine ideas.
12. Create a pull request in GitHub when a change is ready to ship.
13. Record every prompt so reviewers can see the build history.
14. Check changes against design system, security and compliance rules before going anywhere.
15. Keep changes on a separate branch that syncs with the main branch and merges through normal review.
16. Allow teams to publish changes live directly instead of routing them through review.
17. Point each sandbox at dev, staging or production backends and repoint it without changing project defaults.
18. Run each sandbox on its own VM with full terminal access and editable environment variables.

AI does the heavy lifting, people stay in charge

Use AI to interpret permitted inputs, suggest structured mappings and generate candidate outputs for the three 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 fixed framework version and licensed component set; final accessibility and security checks remain with the engineering team. A model suggestion is never a verified fact, professional decision or authorization to act.

What your team sees

Primary screens: Project and environment setup, Editable live preview, Review and merge. Use a thumbnail gallery for projects, a large central editing canvas, and a right-hand panel for components, tokens, prompts and comments. Let users compare variants side by side. Display draft, changes requested and approved states. Provide a preview link with comments anchored to the relevant element. Make the task-specific outcome reviewer-approved interface changes linked to pull requests visible beside its evidence, review state and value baseline.

Accounts and administration

Project ownership, environment 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

Customer-owned repositories, design token files and live data sources. Cloud sandbox hosting, GitHub pull requests and preview link delivery. 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.

   Thirty minutes on your process, your data and how you want to run it: for your own team, or for your clients. You get a fixed scope and price for the MVP.

2. 2

   MVP

   7 days

   One buyer segment, one recurring use case; first modules: edit the real running app interface instead of a static mockup; adjust elements directly in the interface with an edit control. Manual review in the loop. Built by our AI software factory.

   Monthly

   We host, monitor and improve it for a fixed monthly fee, or hand it over to your team. How the retainer works.

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 teams and designers who need to change a live app's user interface without hand-coding every edit use it to solve "interface changes require hand-coding, mockups drift from the real product, and reviewers cannot test changes safely before they ship"?
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 interface changes per design hour and reverted changes after release.
4. Measure, then decide. Track accepted interface changes per design hour and reverted changes after release; 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 framework version and licensed component set; final accessibility and security checks remain with the engineering team. Implement one approved input format, a bounded representative case set and the first two task modules: edit the real running app interface instead of a static mockup; adjust elements directly in the interface with an edit control. Support the third module with operator review: update text, colors, sizes and component styling instantly without writing code prompts. 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 interface changes linked to pull requests. Retain the explicit scope boundary: One fixed framework version and licensed component set; final accessibility and security checks remain with the engineering team.

What the build depends on. Repository access and preview, asynchronous sandbox jobs, editable version history, reviewer access and tested export formats. High-fidelity production requires specialist engineering QA. Obtain representative authorized cases, baseline measurements, qualified reviewers and a buyer-side decision owner. Specific limitation: One fixed framework version and licensed component set; final accessibility and security checks remain with the engineering 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 interface package. Offer a monthly production allowance after repeat demand. Quote complex integrations or specialist accessibility work separately. These are test prices, not market benchmarks. Package the initial sale as one bounded reviewer-approved interface changes linked to pull requests. 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 hand-coded interface work while keeping every change reviewable and reversible. Demonstrate a concrete reviewer-approved interface changes linked to pull requests using the buyer's approved example and show the baseline, corrections and actual delivery effort.

Where to find buyers

Product teams and designers who need to change a live app's user interface without hand-coding every edit 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 interface changes linked to pull requests from a small authorized input set, with a transparent calculation of accepted interface changes per design hour and reverted changes after release and no promised savings.

The first 30 days

1. Week 1: interview five product teams and designers who need to change a live app's user interface without hand-coding every edit and inspect a recent example of interface changes require hand-coding, mockups drift from the real product, and reviewers cannot test changes safely before they ship.
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 interface changes per design hour and reverted changes after release, 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 interface changes per design hour and reverted changes after release. 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 interface changes per design hour and reverted changes after release; 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 interface changes linked to pull requests. 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 components, design constraints and review examples, together with reliable delivery for a narrow product niche. Build a permissioned library of representative task cases, reviewer corrections and verified operating constraints for product teams and designers who need to change a live app's user interface without hand-coding every edit. Repeatable delivery and useful integrations matter more than access to a base model.

Alternatives and positioning

Modeinspect, Remix and Lovable Visual Edits, plus hand-coding and static mockups. Compare this product with the buyer's present method on accepted interface changes per design hour and reverted changes after release. Offer a bounded paid workflow instead of claiming broad autonomous expertise. Market uniqueness and competitor coverage are not verified.

Main delivery costs

Generation attempts, sandbox compute, storage, reviewer hours, client revision rounds and licensed source components. Additional initial validation requires representative authorized sample preparation, buyer interviews, buyer-side evaluation and bounded validation of reviewer-approved interface changes linked to pull requests. Track cost per accepted output, including correction work, unsuccessful cases and support.

Preserve source attribution, accessibility requirements and usage permissions. Engineering teams approve substantive changes and publication scope. One fixed framework version and licensed component set; final accessibility and security checks remain with the engineering team. Keep all consequential actions under authorized human control and do not fabricate missing inputs, permissions, professional judgments or market evidence.
