Generate precision prompts
for high-end residential architecture.
A web-based prompt studio that turns your design intent — material, atmosphere, viewpoint, region, and lifestyle — into a structured, production-ready text prompt. No templates to memorize. No blank-screen frustration.
Launching November 2026
There is no waiting list and nothing to sign up for. New batches of nine images — each produced with this studio — are published on an ongoing basis. Follow along, then come back in November.
What it is
TRANEXION Prompt Studio is a professional web application for architects, interior designers, luxury residential sales professionals, and premium residential developers who generate architectural imagery using AI image tools. It lets you compose detailed, structured prompts through a chip-based UI — selecting material palettes, atmospheric conditions, geographic region, viewpoint, and more — then copies the result straight into your clipboard.
The studio is optimized for Midjourney, the AI image generation platform used by leading design professionals. Each chip set is tuned to Midjourney's prompt grammar, keeping output under its 1,024-character quality threshold (the studio includes a live character counter that warns before the limit is reached; the hard input cap is 1,500 characters) and avoiding vocabulary patterns known to degrade image coherence.
TRANEXION's prompt library is structured around a coordinate system spanning 6,561 addressable positions (81 aesthetic cells × 81 scene positions across four design axes: nine Nuance variations × nine Region archetypes × nine Area categories × nine Visual Phenomena). 342 of them are published today, with new images added in batches of nine, on an ongoing basis. The resulting images are published at /works/ and /works-vertical/. The studio surfaces this structured vocabulary as interactive selection chips, so you get research-backed prompt grammar without memorizing it.
The target user is a specialist working in the premium residential segment — someone who needs vivid, high-resolution architectural imagery to align design vision with clients at the earliest stage of a project, before floor plans or detailed renderings exist.
Why not borrow someone else's project photos?
Many architects, interior designers, and luxury home sales teams still share other people's finished project photos — from Pinterest, design portfolios, or catalog imagery — to align early with clients before drawings or renderings exist. It is a familiar shortcut, and it often works until it does not.
Brand anchoring. When a client falls in love with a specific photograph, they may anchor on that built project — another firm's house, another builder's brand — instead of your design direction. The conversation shifts from what you can create for this client to how closely you can copy someone else's work.
Copyright exposure. Third-party architectural photography is protected work. Using it in client proposals, sales decks, or social posts without a clear license can create intellectual-property exposure. Not every informal use is treated the same way in every jurisdiction, but the risk is real enough that many firms quietly avoid the question rather than resolve it.
Client confidentiality. Your best completed homes may be the ones you are least allowed to show. When homeowners decline new photography — for privacy, security, or personal preference — sales and design teams still need proof of capability for the next prospect. Reusing older images, informal snapshots, or “just this once” deck slides can exceed what those clients agreed to, even when the work is entirely yours. That quiet workaround carries reputational and contractual risk that copyright law alone does not cover.
Prompt friction. Some teams already use Midjourney — yet revert to borrowed photos when results miss the vision. Design judgment lives in the eye and the hand; the model reads compressed English, not intuition. Learning that translation through trial and error often takes longer than falling back on Pinterest, old decks, or hand sketches — so the familiar shortcut returns. Competitors who systematize prompts move faster on early alignment while you stay slow and still tied to imagery you cannot safely reshare.
What Prompt Studio changes. The studio does not supply images — it helps you compose structured, project-specific English prompts(material, atmosphere, region, viewpoint, scale) that you paste into Midjourney or a compatible tool. You can also save your own proven prompt fragments as ORIGINAL chips with private, device-only thumbnails — not only TRANEXION's catalog chips. Prompt Studio helps you bring new prospects ideas that feel fresh to this conversation — instead of circulating a prior client's home — or any other homeowner's completed project — as your reference. Rights to images you generate are governed by your AI platform's terms, not by this subscription — see What's not included.
The free catalog at /works/shows what this vocabulary can produce. The subscription gives you the tool to build your own prompts for your own projects — without borrowing another firm's finished work as the starting point.
See it in operation
Just over a minute, unedited: selecting axes, stacking chips, and copying the finished prompt. Press play to start; pause at any point to read the prompt as it is built.
What's included
- Full access to the Prompt Studio web application — chip-based UI covering material, atmosphere, viewpoint, region, scale, placement, and custom free-text lanes.
- Privacy-first, device-only storage — saved presets, session state, and the prompts you compose stay in your browser only (localStorage and IndexedDB). TRANEXION does not upload or store your prompt content on its servers. Export to JSON on your machine for backup or device transfer (toolbar Download/Upload and Settings bulk export); the file stays under your control.
- ORIGINAL chips with your own thumbnails — Save prompt lines you have already proven in Midjourney as reusable chips in the lane where you work. Attach a small reference thumbnail from your machine so you can recognize and re-insert the phrase in one click. Your ORIGINAL library (prompt text, names, and thumbnails) stays in your browser only — it is not uploaded to TRANEXION or shared with other subscribers.
- Complete prompt chip library — all current chips across every axis, with new additions released during the subscription period at no extra charge.
- One-click copy to clipboard — structured output formatted for direct paste into Midjourney or compatible tools.
- Drag-to-reorder prompt lines — move whole phrases up or down in the lane in one gesture, without the copy-paste reshuffling prompt users repeat when phrase order changes the image.
- Chip-level color coding — visual grouping by semantic axis (material, atmosphere, region, etc.) for faster composition.
- Named color assignment — associate material-specific color prefixes with individual prompt chips.
- Free-text insert lane — append any custom phrase to the generated prompt without breaking the structured output.
- Usage in English only — prompt output is English, optimized for Midjourney's English-primary grammar.
- Access on any modern web browser — no installation, no desktop app required.
- Ongoing chip updates — new prompt vocabulary added as the TRANEXION architectural catalog expands.

Once checkout is open, sign-in details are sent by email to the address you used at Paddle, shortly after checkout. Access is per-subscriber and remains active while the subscription is current. There is nothing to install; Prompt Studio runs in the browser.
What's not included
The subscription grants access to the TRANEXION Prompt Studio web application only. The following are explicitly outside the scope of this subscription:
- AI-generated images — the studio produces text prompts only. Image generation requires a separate account with an AI image platform (e.g., Midjourney).
- AI image platform subscription or credits — Midjourney or any other image generation service is billed separately and independently.
- Design consulting or project services — TRANEXION Prompt Studio is a software tool, not a consulting or agency service.

- Live support or 1:1 sessions — subscription does not include direct support calls or training sessions.
Frequently asked questions
How will I know when it launches?
There is no waiting list, and no email address is collected. New images are published regularly on Instagram and Pinterest — typically nine at a time, each produced with this studio. Follow either account and the launch will be announced there, or simply return to this page in November 2026.
Who processes my payment?
All payments are handled by Paddle (Paddle.com Market Limited), which acts as the Merchant of Record. You will receive receipts and invoices from Paddle. Applicable sales tax and VAT are calculated and remitted by Paddle.
How do I cancel my subscription?
You can cancel anytime through the Paddle customer portal linked in your billing receipt. After cancellation, access continues until the end of the current billing period. No partial refunds are issued for unused days within a billing period.
What is the refund policy?
Because the product is a digital service with immediate access upon subscription, no refunds are issued as a general rule. Refunds are governed by Paddle's refund policy and applicable law. Please see our Refund Policy and contact info@tranexion.co.jp for specific enquiries.
Can I use this in client presentations?
Prompt Studio produces text prompts only. You generate images separately in Midjourney (or a compatible platform) under that platform's subscription and terms. The intended workflow is to stop relying on borrowed or gated project photos — including other firms' finished work or past client homes you are no longer cleared to show — for early vision alignment. Instead, show visuals built from prompts composed for this project — material, region, atmosphere, and viewpoint you control — so new prospects see ideas that feel fresh to this conversation, not a prior homeowner's completed project passed around as the reference. Whether a specific generated image is appropriate for a given client presentation depends on your platform license and local law; this product does not grant image rights.
Why is there no free trial?
The core value of the product is its curated prompt vocabulary, which represents a significant research and editorial investment. A free trial would allow extraction of that vocabulary without a meaningful commitment. The TRANEXION architectural catalog — 342 images published today across a 6,561-position coordinate system, growing steadily — nine images at a time — is available for free at /works/ and /works-vertical/ so you can evaluate the design quality before subscribing.
Where is my work stored? Do you keep my prompts on your servers?
No. Saved presets, session state, and the prompts you compose are stored only in your browser (localStorage and IndexedDB). TRANEXION does not receive or store your prompt content. You can export the current canvas or your saved preset library to JSON files on your computer for backup or to move work to another device; import reads those files locally in the browser. Subscription sign-in and the chip catalog are served by TRANEXION; your creative work is not.
Which AI image tools is this compatible with?
The prompt output is optimized for Midjourney. The structured English text output may also be used with other AI image generation tools that accept natural-language prompts, but optimization and testing have been performed specifically for Midjourney's prompt grammar and character limits.
Why is Prompt Studio optimized for Midjourney?
Early discovery in premium residential work is not only about sharing a fixed image — it is about exploring direction together. Premium residential clients often want something that does not look like a catalog reference.
Midjourney goes beyond literal prompt execution and leaves room for serendipity. Its Aesthetics controls (Stylization, Weirdness, Variety) let the model interpret like a creative collaborator, not a photocopier. That interpretive range is why Prompt Studio targets Midjourney.
In what language is the interface and output?
The application interface and all prompt output are in English. The product is intended for English-speaking design professionals.
How do I get access after subscribing?
After checkout, sign-in details are sent by email to the address you used at Paddle, shortly after checkout. Access is per-subscriber and remains active while the subscription is current. There is nothing to install; Prompt Studio runs in the browser.
Does my work sync across devices?
No. Prompts, saved presets, and session state are stored in your browser only (localStorage and IndexedDB) — they are not uploaded to TRANEXION’s servers and do not sync automatically across devices. To move your work to another device, use the JSON export in the toolbar (Download) or in Settings — save the file on one device and upload it on the other. Your subscription sign-in simply unlocks access to the application; it does not store your creative work in the cloud.
