Renderz
Renderz is a Swiss browser-based AI rendering tool that turns floor plans, sketches, model views or site photos into photoreal architectural images in about thirty seconds, preserving the layout and proportions you upload.
What is Renderz?
Renderz is an AI rendering service for architecture and interior design, published by the Swiss company Lorem Consulting Sàrl in Sonceboz. It runs entirely in a browser and is built around a single claim: that you can reach a client-ready image without a 3D pipeline — no CAD licence, no scene setup, no render farm, no plug-in to install.
The workflow is deliberately short. You upload a floor plan, a sketch, a screenshot of a 3D model or a photograph of an existing site, describe the result you want in ordinary language, and get a photoreal image back in roughly thirty seconds. Prompts can be typed in any language.
Architecture-Aware AI is the capability the product rests on. Renderz says its engine tells a top-down plan from a perspective view and preserves the layout, openings and proportions of the source, so that reviewers argue about design intent rather than about distortions a generic image generator introduced. The publisher is candid that source-guided generation remains subject to drift, and devotes a comparison page to the cases where a traditional renderer is still the safer choice.
Three creation modes sit on that engine. Render Mode converts an input image into a finished render. Inspiration Mode produces concept directions and moodboards from a prompt alone, before any geometry exists. Motion Mode animates a finished still into a short cinematic clip for decks, listing pages and social media. Three further capabilities complete the set: material variants across a fixed room and camera, 4K upscaling of an existing image, and a built-in 2D plan editor that lets you trace walls on a snap-to-grid canvas, set the wall height and position the camera when no source file exists.
A furniture catalogue places real products at correct scale, and targeted edits can be described in plain language while the rest of the image stays intact.
The site addresses architects, interior designers, landscape architects, urban planners, estate agents, property developers, kitchen and bath designers, furniture designers and renovation contractors, with a dedicated page for each, and is published in English, French, German and Spanish.
What it does
- Turn a floor plan, sketch, model view or site photo into a photoreal image in about 30 seconds
- Preserve the uploaded layout, openings and proportions instead of letting the AI reinvent the space
- Draw walls on a 2D canvas and place a camera to create a view with no source file at all
- Furnish a scene with correctly scaled real products from a built-in furniture catalogue
- Generate material, palette and atmosphere variants on the same room and the same camera angle
- Edit one detail in plain language without regenerating the rest of the image
- Upscale a finished render to 4K, or animate it into a short presentation clip
When to use Renderz / When not to
A quick filter to help you decide if Renderz is the right fit.
When to use Renderz
- Architects who need a credible visual for a design review without opening a rendering pipeline
- Interior designers furnishing rooms from a product catalogue and testing finishes with clients
- Estate agents and property developers staging empty listings or selling units before completion
- Small studios and solo practitioners with no in-house visualisation team or render farm
- Landscape architects, urban planners and renovation contractors presenting to non-specialist audiences
When not to use Renderz
- Teams producing final marketing campaigns that must match approved product specifications
- Anyone needing coordinated camera sets, animation or exact shadow studies from one controlled scene
- Practices expecting a plug-in or native file import — Renderz reads exported images only
- Users wanting commercial rights on the free tier, which is restricted to personal use
- Buyers who require published terms, a DPA or documented model-training guarantees before signing
How to use Renderz
A typical end-to-end flow, from setup to results.
- Create an account with an email address or a Google sign-in — no credit card is required
- Choose a source: a floor plan, a 3D model screenshot, a hand sketch or a photo of the site
- Alternatively, open the 2D plan editor, trace walls and openings on the snap-to-grid canvas and set the wall height
- Place a viewpoint on the plan and aim the field of view so the image matches the angle you intend
- Upload the image, or send the captured view straight to the engine
- Describe the look you want in plain language — materials, palette, season, time of day
- Wait around thirty seconds for the render to come back
- Refine by adjusting the prompt, or describe a single change to edit one detail without redoing the image
- Generate material and atmosphere variants on the same room and camera angle to compare directions
- Upscale the chosen image to 4K, or animate it into a short clip, then take it into the presentation
Pros & Cons
Pros
- Geometry fidelity is the stated design goal rather than an afterthought — a real differentiator against generic image generators
- No 3D skills, CAD licence, plug-in or render farm required; everything happens in the browser
- A roughly thirty-second turnaround makes it practical to iterate live in a client meeting
- The built-in 2D plan editor means you can start with no source file at all
- Five free renders with no credit card, enough to judge the tool on a real project
- A named Swiss publisher, with a published address, controller and a policy written against both the FADP and the GDPR
- An unusually candid resource library, including a comparison page that names the limits of AI rendering
Cons
- No terms of service, legal notice or contact page anywhere on the site — only a privacy policy
- The privacy policy never mentions model training, so there is neither a commitment nor an opt-out
- No published DPA, no Article 27 EU representative and no data protection officer
- No support email and no contact form; the only address published is the data protection one
- No genuine software integration: native CAD and BIM files are not imported and no plug-in exists
- No API, no mobile application and no browser extension
- A very young product — the domain dates from January 2026 — with the free tier capped at five renders for personal use only
Pricing & Plans
Renderz offers a permanent free tier at 0 CHF, limited to five renders in total and to personal use. The lowest paid entry point is the Solo plan at 35 CHF per month on monthly billing; the Studio plan is charged at 80 CHF per seat per month. An annual commitment reduces both paid plans by 20 per cent. Note that the displayed currency follows the market detected from the visitor's location, so the same figures are billed in Swiss francs, euros or US dollars depending on the country.

Data, GDPR & hosting
A consolidated view of how Renderz handles your data.
GDPR overview
Renderz states that it processes personal data under the Swiss Federal Act on Data Protection (FADP/nLPD) and, where applicable, the EU General Data Protection Regulation. The controller is named in full — Lorem Consulting Sàrl, Vers l'Ouest 2, 2605 Sonceboz, Switzerland — with joey@renderz.ch as the single data protection contact. The policy, dated 19 July 2026, lists the expected rights: access, rectification, erasure, objection, restriction, withdrawal of consent and portability, and directs complaints to the Swiss FDPIC. Consent handling is granular: analytics and advertising cookies stay blocked until opted in, refusal is given equal prominence, and a minimal consent audit is kept for thirty days. Two gaps stand out for a policy that invokes the GDPR: no Article 27 EU representative is designated, and no data protection officer is named.
Who owns the data?
Renderz publishes no terms of service, so no contractual clause assigns ownership of uploaded material or generated renders to the vendor. The privacy policy treats floor plans, sketches, photos, prompts and the renders produced from them as your content, kept for the life of your account and deleted or anonymised afterwards. What the site does state is a usage right rather than a transfer of ownership: the Solo and Studio plans include commercial usage suitable for presentations, boards and marketing collateral, while the Free tier is explicitly limited to personal use. In the absence of published terms, the precise ownership position remains undocumented and worth confirming in writing.
Reuse rights
On the paid tiers the position is explicit: Solo and Studio include commercial usage rights, so renders can be reused in client presentations, competition boards, brochures, listing pages and marketing collateral without asking further permission. The Free tier carries the opposite restriction, described on the pricing card as personal use only. Separately, the privacy policy sets out how Renderz itself uses your data: to provide and secure the service, manage accounts and subscriptions, answer requests, analyse and improve the site, and meet legal obligations — relying on contract, legitimate interest, consent or legal duty depending on the case. Nothing in the policy addresses whether uploaded content feeds model training, in either direction.
Data retention & training
Hosting summary
Renderz does not state where user data is stored. The privacy policy identifies its providers by name — Supabase and Vercel for hosting and database, Stripe for payments, Resend for transactional email, DataFast for analytics, and Google and Meta for advertising measurement — but attaches no region or country to any of them. What the policy does say is that some providers sit outside Switzerland and the EU/EEA, in particular in the United States, and that transfers abroad rely on adequacy decisions or standard contractual clauses. The Meta Pixel may itself transmit data to Meta Platforms, including in the United States. The controller is Swiss, based at Sonceboz, and the policy is written against the Swiss FADP with the GDPR applied where relevant. One technical detail should not be misread: the domain resolves to a Vercel anycast address geolocated in the United States, which identifies a content-delivery edge node rather than the jurisdiction in which project files are actually stored. Anyone with data residency obligations will need to ask the vendor directly.
Things to keep in mind
Risks and trade-offs to weigh before adopting Renderz.
- Uploaded plans, sketches and site photographs are client material; with no terms of service published and no statement on model training, the vendor's position on reusing them is simply undocumented
- A photoreal image reads as a promise, and the publisher warns of it directly: a compelling concept render can become an accidental technical commitment if it is passed off as a validated deliverable
- Generative drift is acknowledged by the publisher — a moved opening or a simplified roof edge can survive into a client document if nobody checks the architecture against the source
- Speed encourages volume: producing twenty variants in an hour can substitute quantity for design judgement and shift a review from what is right to what looks best
- The Free tier forbids commercial use, so putting a free render into a paid client deliverable breaches the plan's own terms
- No published DPA and no Article 27 EU representative, which matters if you process EU clients' project data through the tool
- Sustained reliance on prompt-driven visuals can erode the modelling and drawing skills that let a practice judge whether an image is plausible in the first place
Setup & Integrations
Technical difficulty
Very low. There is nothing to install: Renderz runs entirely in a browser, with no CAD licence, plug-in, extension or scene configuration involved. You sign up with an email address or a Google account, without a credit card, and the first image needs only an upload and a sentence of direction. The only preparation worth doing is on the CAD side — exporting a clean view with legible edges, openings and perspective. Users with no source file can draw one in the built-in 2D plan editor instead. The publisher puts first results in minutes, each render taking about thirty seconds.

Should you pick Renderz?
Renderz is a narrow tool that does one thing and says so plainly: it turns the drawings and photographs an architect already has into images a client can read, without a rendering pipeline. That focus is its strength. The Architecture-Aware AI claim — separating plans from perspectives and holding walls, openings and proportions in place — is the difference between a render you can put in a proposal and an image you have to explain away, and the publisher argues it seriously rather than sloganeering. The thirty-second turnaround and the built-in 2D plan editor make it genuinely usable inside a meeting.
It is also unusually honest about its own limits. The resource library includes a comparison page that concedes generative drift and sends you back to a traditional renderer when you need coordinated cameras, exact product assets, animation or deterministic shadow studies.
The reservations are documentary rather than functional. There are no terms of service, no legal notice and no contact page — only a privacy policy, which is clear and names a real Swiss controller, but which never says whether uploaded plans and photographs feed model training, and offers no opt-out. There is no DPA, no Article 27 representative and no support address. For a practice uploading confidential client projects, those are questions to put to the vendor in writing before subscribing.
Expect no software integration either: the nine pages devoted to Revit, Rhino, SketchUp and the rest describe exporting an image by hand, and the publisher says so itself.
The product is new — online since January 2026 — behind a company registered since 2018. Five free renders and no credit card make the trial cheap enough that testing it on a real project is the sensible way to decide.
