Ritn3D

Overview

Ritn3D uses neural networks to identify walls, doors, windows and rooms in PDF, JPG or PNG plans, including CAD exports, scans and photos of printed drawings. Users can inspect and adjust the detected layout before generating a model, an important safeguard when an automated reading needs correction. Most conversions take under two minutes, depending on plan complexity, according to the company.

The result is an interactive 3D model for exploring and walking through a layout. Shared models open in a browser without requiring recipients to install the app or sign in, which makes it easier to circulate a proposal with a client or household. Uploads are processed securely and not shared with third parties; shared links are access-controlled and can be revoked. Free renders remain available for seven days, while Pro includes 90-day cloud sync.

Key features

• Plan recognition and editing: Automatic detection handles core architectural elements, and the editable detected layout gives users a chance to correct errors before rendering. Hand-drawn or heavily annotated plans may still need manual correction.
• Interactive sharing: Browser-based viewing avoids an app or account requirement for recipients, useful when contractors, clients or family members need to review a design without adopting another tool.
• Exports: JPG, PDF, GLB and STL are supported formats, but download quotas matter: Pro+ includes 10 GLB or STL downloads per month, with extra downloads at $3.99 each.
• Integrations: Design-partner integrations can embed the editor and viewer in another product. The partner API is discussed with prospective partners, so this is aimed at product businesses rather than ordinary project teams.

Pricing

Ritn3D has a free plan and a 7-day trial. The free tier costs 0.00 USD per free and allows 3 renders per month, bird’s-eye views, standard textures, sharing with up to 5 people and an unlimited floor-plan editor. Free renders last seven days. This is enough for occasional previews, but the render cap and bird’s-eye-only view limit its usefulness for repeated client walkthroughs.

Pro costs 9.99 USD per month, billed month-to-month. It raises the allowance to 20 renders per month and adds walkthroughs, furniture, Full HD, sharing with up to 50 people, no watermark and 90-day cloud sync. For homeowners or smaller teams that need a clearer presentation and recurring access, these are the most relevant upgrades.

Pro+ costs 19.99 USD per month, billed month-to-month, for 40 renders per month and 10 GLB or STL downloads per month; additional downloads cost $3.99 each, with rollover. It suits users who need downloadable models, though export-heavy work should account for the per-download charge. Enterprise has custom pricing, custom render volumes, a white-labelled viewer, volume pricing and partner API integration; it is for organisations embedding Ritn3D or negotiating larger usage, not a standard household project.

Platforms

Ritn3D is available on Android, iOS, web and Windows. Its browser viewer also means recipients can review shared models without installing the app or logging in.

Who it's for

The company names real estate agents, architects, interior designers, homeowners and builders as intended users. Homeowners can use it to understand a proposed layout, while contractors and design professionals can share a model for review. The single-floor limit is decisive: projects requiring a model of multiple floors in one upload will need another approach. The company invites questions through its support contact and says it will respond as soon as possible.

Pros and cons

• Pro: PDF, JPG and PNG input covers digital plans as well as scans and photos, so users need not start with a specialised file type.
• Pro: Reviewing and adjusting detected elements before generation gives users a way to catch recognition mistakes before sharing.
• Pro: Recipients can explore shared models in a browser without an account or app, reducing friction in project discussions.
• Con: Each upload creates a single-floor model, ruling out a complete multi-level representation from one upload.
• Con: Hand-drawn or heavily annotated plans may require manual corrections, weakening the speed advantage for less clean source drawings.
• Con: The free plan caps use at three monthly renders and sharing with five people, while Pro+ export downloads are capped and extra downloads cost $3.99 each.

Alternatives

For a wider set of floor-plan tools, browse AI floor plan generators.

Choose Planner 5D if you want to upload a floor plan and convert it into a 3D project with a full premium furniture catalog; its Premium plan is 59.99 USD per year, billed annually. CubiCasa is an alternative for 2D floor plans with room dimensions and PNG or JPG output on its free LITE plan. FloorAI offers four free AI floor-plan generations and an editor for users focused on generating or editing plans rather than converting an existing plan into Ritn3D’s interactive model. FloorDrafter is another web-based freemium option, with free signup and daily check-in credits and watermarked PNG output.

RoomSketcher may suit users who want a free AI floor-plan conversion alongside 2D and 3D floor plans, snapshots and AI rendering. BuildFloorPlan offers two free generations, sketch or image uploads, a seven-day history window and exports, making it an option for users whose priority is generating a plan from an image or sketch. Metaroom offers a 30-day Pro trial with unlimited scans and all export formats, an alternative for those seeking a time-limited trial of its scanning workflow. Luw.ai Studio offers two daily free credits at 512×512 resolution with a watermark, for users considering a broader AI-creation tool.

Verdict

Ritn3D is a sensible choice for homeowners and building professionals who want to turn a clean, single-floor plan into a model they can review and share without asking recipients to install software. The editable detection stage and straightforward browser sharing make it useful for layout conversations. Look elsewhere if the project needs multiple floors in one model, or if annotated drawings and frequent 3D exports make its correction burden and quotas a poor fit.
