Pencil

Pencil is a browser-based jewelry design and commerce platform for jewelers and brands building configurable products. It is most compelling when a business needs both production-ready STL files and website builders; the free tier is sharply limited for ongoing AI work.

Overview

Pencil joins jewelry design tools with manufacturing exports, product imagery, and online commerce features. Editable templates, stone settings, custom 2D and 3D uploads, AI-generated 3D elements, and advanced parameters give designers several routes into a project. That jewelry focus is useful for teams creating configurable products, though the stated export format is STL alone.

Key features

Design and production

Parametric modeling and stone-setting tools make Pencil a focused option for jewelry work rather than a general-purpose design canvas. Users can work from editable templates, bring in their own files, or generate 3D elements with AI. Designs can be downloaded as production-ready 3D STL files, which connects design to manufacturing; teams dependent on other export formats may find that narrower than their workflow requires.

Imagery and commerce

The Professional plan includes an e-commerce and product photo generator, and Pencil's design tools can create studio-quality product photos. Pencil Shop adds ring and pendant builders for websites, plus lead capture, quoting, live pricing, and add-to-cart tools. These features make the platform more useful to brands selling customizable jewelry than to designers seeking only modeling tools.

Integrations and API

Website configurators can be deployed on platforms including Shopify and Wix through app integrations. Enterprise adds headless API access for making existing products configurable and customizable, a more relevant path for businesses integrating Pencil into their own product systems than for a small studio with a standalone design workflow.

Pricing

Pencil has a free tier and paid plans billed monthly, with Enterprise on custom pricing. The plans differ not just in AI credits, but also in design capacity, builders, and order volume.

• Free — free, free forever: Includes 0 AI credits, a 3-design limit, STL downloads, and uploads of your own files. It is a no-cost way to try the core design workflow, but the absence of AI credits and the small design cap make it a poor fit for regular production.
• Professional — $39 a month: Includes 200 AI credits per month, unlimited designs, STL downloads, and priority support. This is the entry point for designers who need ongoing AI use and room for a growing design library, without the builder and order allowances of the Shop plans.
• Pencil Shop — $199 a month: Includes 2,000 AI credits per month, up to 3 builders, and up to 400 orders per month. It suits a business launching a small number of online configurators with moderate order volume; the builder and order ceilings matter as sales grow.
• Pencil Shop Pro — $499 a month: Includes 5,000 AI credits per month, up to 10 builders, and up to 1,000 orders per month. The higher limits fit businesses managing several configurators and larger order volumes, at a substantial increase over Shop.
• Enterprise — custom pricing: Includes custom tools and features, a custom AI credit package, and a custom-trained AI design agent. Unique settings, parametric templates, and wholesale markup tools are also part of the Enterprise offering, making it the tailored option for larger or more specialized operations.

Platforms

Pencil is available in a browser, with API access included in the Enterprise offering. Its website configurators can also be deployed on platforms such as Shopify and Wix through app integrations.

Who it's for

Pencil is a strong fit for jewelers and jewelry brands that want to connect design work to manufacturing and online customization. Professional serves designers who need more than the free tier's three designs and no AI credits. Shop and Shop Pro are for businesses that need website builders and have order volumes that fit their respective caps. Startups can explore the free plan, while businesses requiring custom tools, API integration, or tailored AI capabilities are better matched to Enterprise. It is less suitable for anyone who needs a free AI allowance or relies on export formats beyond STL.

Pros and cons

• Pro: Jewelry-specific modeling and stone-setting tools, plus editable templates and uploads, support multiple design approaches.
• Pro: Production-ready STL downloads create a direct path from design to manufacturing.
• Pro: Shop plans combine website builders with lead capture, quoting, live pricing, and add-to-cart tools.
• Con: The free plan has no AI credits and caps designs at three, limiting its use beyond initial exploration.
• Con: STL is the only named export format, which may not suit teams requiring other manufacturing files.
• Con: Shop plans cap builders and monthly orders, while the higher allowances cost more.

Alternatives

For a broader comparison of jewelry-focused tools, browse Jewelry Design Software.

• Diatech Studio is worth considering when a free plan with 25 images and full access to AI features matters more than Pencil's jewelry configurators and manufacturing workflow.
• Kerf is the alternative for users who prefer free, locally run software with no accounts or billing under an MIT license.
• Rhino 3D is another option for buyers considering a permanent commercial license rather than Pencil's monthly plans.
• ZBrush offers an iPad free plan with 28 brushes for users seeking a different design tool.
• 3Design CAD is another paid jewelry CAD option.
• Facetra is an alternative for users looking at a one-time Starter plan with 100 renders or refines and Indian style presets.
• Autodesk Fusion is an alternative for users who want integrated CAD/CAM, team collaboration, or PCB design.
• CounterSketch is another paid jewelry design option with an annual membership.

Verdict

Choose Pencil if your jewelry business needs to carry configurable designs from creation into STL manufacturing exports and online sales tools. Its main advantage is that combination of jewelry-specific design, product imagery, and commerce in one platform. Look elsewhere if you need broader export-format support or a free plan that includes AI credits.
