2. Feature-by-Feature Comparison
Next, we’ll compare Rerender AI and Spacely AI across six key criteria:
- Ease of Use and Learning Curve
- Rendering Quality and Speed
- Pricing Models and Value Proposition
- Integration Capabilities
- Output Formats and Resolution Support
- Customer Support and Community Resources
By reviewing each category in detail, you’ll see how these two AI rendering tools differ and which platform is better suited to your workflow.
(1) Ease of Use and Learning Curve
1. ReRender AI
Rerender uses a form-based workflow with step‑by‑step guides. Upload an image, choose the style and details, and get a render in minutes. It is very friendly to beginners, and advanced users can also quickly adjust parameters to get the desired results.
2. Spacely AI
Spacely AI places all controls on a single, page, functions on the left, preview in the center, and actions at the bottom. Confusing for beginners, but manageable for experienced AI users, its dense interface makes operation feel heavy.
3. Conclusion
For ease of use, Rerender AI clearly wins with its intuitive, guided workflow, making it ideal for quick adoption and rapid iterations. By contrast, Spacely AI’s dense interface and lack of guidance make it poorly suited for new users and even advanced users.
(2) Rendering Quality and Speed
For designers, image quality and rendering speed are the top priorities when choosing an AI rendering tool. In our test, we used the same SketchUp model to compare output and time for both platforms.
1. ReRender
Quality Analysis: Soft, natural style with high material accuracy and realistic lighting. Generates 4 images per run, making it easy to compare and select the best result.
Generation Speed: Very fast, about 25–30 seconds for 4 images
2. Spacely
Quality Analysis: Supports multiple rendering mode, giving designers flexibility in presentation. The output is slightly sharp, but the sense of depth and spatial atmosphere is relatively weak.
Generation Speed: Slow, about 80–90 seconds for 4 images.
3. Conclusion
Rerender AI clearly comes out ahead with its fast, multi‑image generation and soft, natural rendering style. Spacely AI takes 80–90 seconds to produce 4 images, compared to Rerender’s 25–30 seconds, and its sharper, less spatial output makes it less suitable for design workflows.
(3) Pricing Models and Value Proposition
1. ReRender
Free trial: 3 credits per day (1 credit per image), very suitable for newbies.
Price plan (monthly system):
- Unlimited Plan: $45 / month, unlimited image generation.
2. Spacely
Free trial: register to send 10 credits (about 1 credit per picture).
Price plan (monthly system + credit system) :
- Unlimited Plan: $40/month, unlimited image generation.
- Pay As you go: $10/10credit, $20/30credit, $40/80credit, $100/300credit
3. Conclusion
Rerender AI and Spacely AI both provide affordable unlimited plans for frequent users. Spacely AI offers more flexible pay‑as‑you‑go credits, but Rerender AI delivers higher cost‑performance for daily rendering.
(4) Integration Capabilities
1. Rerender AI
Integration: Provides a SketchUp plug‑in that allows users to render directly from their environment. Supports API access.
2. Spacely AI
Integration: Provides a SketchUp plug‑in that allows users to render directly from their environment like Sketch Up.
3. Conclusion
Rerender AI and Spacely AI are evenly matched in integration capabilities. Both provide a Sketch Up plug‑in for direct in‑model rendering , making workflow integration.
(5) Output Formats and Resolution Support
1. Rerender AI
Resolution: Supports two Upscales, up to 4K quality.
Output Formats: Supports still images (PNG), video (MP4), and boards.
2. Spacely AI
Resolution: Supports Enhance Quality
Output Format: Currently only supports still images (PNG).
3. Conclusion
Rerender AI clearly comes out ahead. Rerender AI offers greater versatility with 4K upscales, presentation boards, and MP4 video, while Spacely AI only supports images output and enhance.
(6) Customer Support and Community Resources
1. Rerender AI
Teaching resources: The official YouTube channel releases teaching videos.
Community interaction: recent high quality renderings can be seen on the Home page, and they often collaborate with architecture and design creators.
2. Spacely AI
Teaching resources: There is a tutorial page with teaching articles.
Community Interaction: There is a Blog platform to post information.
3. Conclusion
Rerender AI stands out with its diverse community resources, featuring a example gallery and extensive video tutorials, while Spacely AI mainly provides learning through articles and its blog.
3. Benchmark Table
The table below summarizes the key differences between Rerender AI and Spacely AI across the six comparison criteria:
4. Use-Case Fit
(1) Rerender AI
Rerender AI is well‑suited for high‑frequency design workflows. Its fast multi‑image rendering and beginner‑friendly interface make it ideal for architects and interior designers who need quick iterations and seamless integration with their existing workflow.
(2) Spacely AI
Spacely AI is better suited for occasional, presentation‑focused projects. Its slower, parameter‑heavy workflow suits experienced users seeking stylized outputs, but is less ideal for fast rendering tasks for designers.
(3) Conclusion
Rerender AI is the better choice for most users, offering speed, ease of use, and flexible workflow integration. Spacely AI remains a niche option, best for experienced designers working on stylized renderings.
