Pencil

Pencil is a browser-based platform for jewelry design, production exports, and online product configuration. It is best suited to jewelers and brands that want design tools alongside a route to configurable products and sales. Its appeal is the breadth of that workflow; its free tier stops short of AI credits and allows only three designs.

Overview

Pencil combines jewelry-focused design tools with commerce features. Designers can work from editable templates, upload their own 2D or 3D files, use stone-setting tools, and add AI-generated 3D elements or advanced parameters. Designs can be downloaded as STL files intended for production, while commerce tools help businesses present configurable products on their websites.

This combination will matter most to jewelry businesses that want design and customer-facing customization in one browser-based platform. It is a narrower fit for users who need multiple export formats: STL is the only format named.

Key features

Jewelry design and manufacturing

Parametric modeling and stone settings make Pencil purpose-built for jewelry work. Templates and custom uploads give designers routes beyond AI generation, and production-ready STL downloads connect design work to manufacturing. The Free plan includes downloads, but its three-design cap makes it a constrained way to maintain an active catalog.

Product imagery and commerce

Professional adds an e-commerce and product photo generator, and Pencil says its design tools can create studio-quality product photos. Pencil Shop adds website ring and pendant builders, lead capture, quoting, live pricing, and add-to-cart tools. Configurators can be deployed on platforms including Shopify and Wix through Pencil's app integration, which makes the commerce plans more relevant to businesses already selling through those services.

API and enterprise customization

Enterprise includes headless API access for making existing products configurable, plus custom tools, unique settings, parametric templates, a custom-trained AI design agent, wholesale markup tools, and a custom AI credit package. Those capabilities target brands integrating customization into established products and systems, rather than solo designers looking only for modeling tools.

Pricing

Pencil is freemium. The Free plan costs nothing, billed Free forever; it includes 0 AI credits, a 3 design limit, 3D STL downloads, and the ability to upload your own files. That is enough to explore the workflow, but no AI credits and the small design allowance limit ongoing use.

Professional costs $39 a month, billed per month. It provides 200 AI credits per month, unlimited designs, 3D STL downloads, and priority support. This is the clearest fit for an individual designer or small team that needs ongoing design capacity and AI credits without running a storefront through Pencil.

Pencil Shop costs $199 a month, billed per month, and includes 2,000 AI credits per month, up to 3 Builders, and up to 400 orders per month. It suits a business adding web configurators and order handling, though the builder and order ceilings matter as sales grow. Pencil Shop Pro costs $499 a month, billed per month, with 5,000 AI credits per month, up to 10 Builders, and up to 1,000 orders per month; its larger limits suit higher-volume operations, at a substantial step up in monthly cost.

Enterprise has custom pricing and billing, with custom tools and features, a custom AI credit package, and a custom-trained AI design agent. It is the option for brands needing tailored functionality and API integration rather than a fixed monthly tier.

Platforms

Pencil is browser-based, and its platform information also identifies API access. Enterprise specifically includes headless API access. The web configurators can be deployed on platforms including Shopify and Wix through the app integration.

Who it's for

Pencil is a strong fit for jewelry designers who need parametric and stone-setting tools with STL production exports, and for jewelry businesses that want customers to configure rings or pendants online. Its audience can range from startups exploring ideas to global brands integrating the platform with their websites. It is less suitable for people who need a free AI allowance, export formats beyond STL, or design software without a commerce-oriented workflow.

Pros and cons

• Pros: Jewelry-specific modeling and stone-setting tools, editable templates, and custom uploads support varied design workflows.
• Pros: STL downloads connect designs to production, and commerce plans add builders, quoting, live pricing, and order tools.
• Pros: Professional offers unlimited designs and priority support; Pencil Shop includes a dedicated account manager.
• Cons: Free includes no AI credits and caps designs at three, so it is not a sustained AI-assisted workflow.
• Cons: STL is the only named export format, which may not suit teams whose production process requires other formats.
• Cons: Commerce capacity is capped by plan: up to 3 Builders and 400 orders per month on Pencil Shop, or up to 10 Builders and 1,000 orders per month on Pencil Shop Pro.

Alternatives

Jewelry Design Software is a useful starting point for comparing options across the category.

Diatech Studio is worth considering if image-based AI features and a free plan with 25 images are a closer match than Pencil's jewelry design and commerce workflow.

Kerf is the alternative to consider if you want free, MIT-licensed software that runs locally without accounts or billing.

Rhino 3D is another option to compare for desktop use on Windows or macOS, with a permanent commercial license listed at $995 a month.

ZBrush is worth comparing if you want a desktop option for Windows or macOS; its iPad free plan includes 28 brushes.

3Design CAD is an alternative to explore if you prefer a desktop jewelry CAD option for macOS or Windows and are willing to contact a sales representative about pricing and license options.

Autodesk Fusion may be a better fit when integrated CAD/CAM, real-time team collaboration, PCB design, or electromechanical integration matters; its listed plan is $57 a month, billed annually.

Facetra is an option to compare for web-based rendering, with a Starter plan listed at ₹1,500, paid once for 100 renders or refines and credits that never expire.

JewelForge is worth comparing if you want web-based jewelry design with weight estimates, hollowing, and STL, OBJ, GLB, and USDZ exports; its Artisan plan is ₹799 a month for 8 designs per month.

Verdict

Choose Pencil if you are a jeweler or jewelry brand that wants jewelry-specific design, production STL downloads, and—on the higher tiers—customer-facing configurators and commerce tools in one platform. The main reason to look elsewhere is the combination of a limited free tier and a single named export format; designers who need broader file support or a free ongoing AI workflow should compare alternatives first.
