Pencil

Pencil is an AI design and commerce platform for jewelry, covering design creation, production files, and online buying experiences. Its browser-based design tools include editable templates, stone settings, custom 2D and 3D uploads, AI-generated 3D elements, and advanced parameters. Designs can be downloaded as production-ready 3D STL files. Pencil Shop provides ring and pendant website builders, lead capture, quoting, live pricing, and add-to-cart tools. Configurators can be deployed on platforms including Shopify and Wix through an app integration. The Professional plan includes an e-commerce and product photo generator; Pencil's Design page also describes creating studio-quality product photos. Enterprise includes headless API access for making existing products configurable, along with unique settings, parametric templates, wholesale markup tools, and a custom-trained AI design agent. Free is available forever, with 0 AI credits and a limit of 3 designs, while allowing STL downloads and file uploads. Professional costs $39 a month. Pencil World Inc. is identified as the maker.

Pencil links jewelry design and STL export with commerce tools for online configurators. The free tier has no AI credits and a three-design cap; paid plans begin with Professional at $39 a month.

It suits jewelry businesses or designers who need digital design tools and production-ready STL exports. Pencil Shop and Enterprise features also address teams building online configurators or customizing an existing product catalog.

Pencil suits jewelers and brands that want to connect configurable product design with online selling. Its jewelry-specific tools and STL downloads make it relevant from concept through production, while AI credits and commerce capacity require paid plans.

It is strongest for teams building jewelry configurators alongside their design workflow, not for users who need a choice of manufacturing export formats or free, ongoing AI generation.

Overview

Pencil brings jewelry design, production files and commerce tools into one browser-based platform. Designers can work from editable templates, stone settings, uploaded 2D and 3D files, AI-generated 3D elements and advanced parameters. Designs can be downloaded as production-ready STL files, connecting digital work to manufacturing; the named export format is STL, so buyers who need other formats should look elsewhere or confirm compatibility first.

For online sales, Pencil Shop provides ring and pendant builders with lead capture, quoting, live pricing and add-to-cart tools. Configurators can be deployed on Shopify and Wix through app integration. The Enterprise offering adds headless API access for making existing products configurable.

Key features

Jewelry design and production

Parametric modeling and stone-setting tools give the platform a clear jewelry focus. Templates and custom uploads offer ways to shape designs without relying solely on AI-generated elements. Pencil says its output is production-grade CAD and provides STL downloads, a useful handoff for workflows that accept that format.

Imagery and commerce

Professional includes an e-commerce and product photo generator, and Pencil describes its design page as supporting studio-quality product photos. Shop plans extend the product into customer-facing builders and order workflows. That combination is useful for brands selling configurable jewelry, but the order and builder quotas make plan capacity an important part of the decision.

Enterprise customization

Enterprise features include unique settings, parametric templates, a custom-trained AI design agent and wholesale markup tools. Custom API access is aimed at businesses integrating configurability into existing products rather than relying only on standalone builders.

Pricing

The Free plan costs nothing, is free forever, and includes no AI credits, a three-design limit, STL downloads and file uploads. It is a useful way to assess the design workflow, but the cap and lack of AI credits make it a limited choice for continuing production or regular AI-assisted work.

Professional costs $39 a month, billed per month. It includes 200 AI credits per month, unlimited designs, STL downloads and priority support. This is the entry paid plan for individual designers or teams focused on design and production; it does not include the stated Shop builder and order quotas.

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 fits smaller businesses adding configurators and sales tools to their sites. 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; the higher limits suit larger configurator operations.

Enterprise uses custom pricing and custom billing, with custom tools and features, a custom AI credit package and a custom-trained AI design agent. It is the relevant option for organizations needing the specialized settings, API access or wholesale tools rather than fixed Shop capacity.

Platforms

Pencil runs in a browser and is also offered through an API. Website configurators can be deployed on Shopify and Wix using app integration.

Who it's for

Pencil is a good fit for jewelry designers who need stone-setting and parametric tools, and for brands that want to move from design files to customer-facing product builders. Startups exploring design ideas can begin on the free tier, while global brands can use Enterprise customization and API access. It is a weaker fit for users who need manufacturing formats beyond STL or want free AI credits.

Pros and cons

• Pros: Jewelry-specific parametric modeling and stone-setting tools support a focused design workflow.
• Pros: STL downloads connect design work to production, and paid plans provide substantial AI credit allocations.
• Pros: Shop combines builders with lead capture, quoting, live pricing and add-to-cart tools for online sales.
• Cons: The free plan has no AI credits and caps designs at three, limiting its usefulness beyond evaluation.
• Cons: STL is the only named export format, which may not suit workflows requiring other manufacturing files.
• Cons: Shop plans constrain builders and monthly orders, and scaling from Professional to commerce plans raises the monthly cost.

Alternatives

Explore the Jewelry Design Software directory to compare options by category.

• Diatech Studio is a freemium alternative with Android, iOS, web and other platform support; its free plan includes 25 images and full access to AI features, making it worth considering when image-based AI access matters more than Pencil's jewelry commerce workflow.
• Kerf is a free, MIT-licensed option that runs locally with no accounts or billing; choose it if those terms matter more than Pencil's hosted configurators.
• Rhino 3D is a Windows and macOS alternative with a permanent commercial license and free trial; consider it when a desktop tool and non-subscription license are priorities.
• ZBrush offers a free iPad plan with 28 brushes; consider it for iPad sculpting rather than Pencil's browser-based commerce workflow.
• Facetra is a web alternative with a one-time Starter plan at ₹1,500 that includes 100 renders or refines and credits that never expire; it may suit buyers prioritizing a fixed render allotment over Pencil's recurring credit plans.
• 3Design CAD is a macOS and Windows alternative with a free trial; consider it if a desktop jewelry CAD tool is preferable.
• Drakon is a paid web and Windows alternative with one-time Copilot credit packs; it may fit buyers who prefer purchasing credits rather than paying monthly for them.
• Jewelry CAD Dream is a Windows alternative for buyers considering a paid jewelry CAD product without a free plan or trial.

Verdict

Choose Pencil if your jewelry business needs design and STL production files alongside configurable products and online sales tools. Its main advantage is bringing those stages together, while its key trade-offs are limited named export formats, no free AI credits and recurring plan costs for commerce capacity. If those constraints fit your workflow, the free tier offers a capped starting point and paid plans scale from design into sales.
