about

PRNTD is a project where you can order T-shirts and other merch with designs that you generate iteratively with an AI assistant. Over time we intend to allow you to upload images and work with those, as well as text overlays and so forth. We're happy to have your suggestions on what we should allow you to do.

Today you can only buy one T-shirt or one cell phone case at a time, but we hope to enable groups such as bands or sports teams who want to get a bunch of shirts to benefit from not having to pay individual shipping on each unit and hopefully get some sort of group discount, while allowing them to custom design their shirts and order them as a package — or maybe other merch as well, like mugs.

We have ideas of creating a marketplace where you can sell your designs and raise money for your team or your cause. The intention of this project is to be a not-for-profit platform in service to the community, not trying to make a lot of money.

    Automated browser testing now runs on every code change: pull requests get a live preview deployment exercised end-to-end (guest shopping flow, cart, checkout) on phone and desktop before merging. Also fixed a chat bug where raw structured data occasionally appeared in the design assistant's replies.

    Improved checkout so shipping is billed separately, ensuring percentage discount codes apply only to the product and never erode shipping margin. Added a per-order price breakdown and strengthened automated testing and CI with type-checking and coverage reporting.

    Launched community design-sharing on PRNTD this week. Designers can publish individual images to a discover feed (titles auto-written by AI), and visitors can branch off any published design into their own private starting point with one click. Each fork makes its own copy of the seed image so designs stay independent.

    Major data-model rework alongside the move to native-transparent image generation. Ideogram's transparent output went live, retiring most of the background-removal pipeline. The design-asset model migrated to a dedicated primary-image column with dual-write and backfill (fifty-seven designs), the preview page was rewritten as a pure function of design and product, and bulk Printful pre-fetching landed on order accept. The JSON chat-history column was replaced with an append-only chat-message table, with four hundred and eight messages migrated cleanly.

    Opened the codebase up. Made the repository public, added branch protection, CI, and contribution guidelines, and onboarded a first external collaborator who landed their first pull request. Shipped a PRINTFUL_DRY_RUN flag with tests and an end-to-end runbook so the build pipeline can be exercised without spending real Printful budget. Worked through several background-removal approaches and validated Ideogram's native transparent generation as a viable replacement.

    Model upgrade work. Moved the design AI to claude-sonnet-4-6 ahead of older-model retirement, fixed compatibility issues, and added a women's relaxed tee with twenty-two colors. Began splitting the project onto its own Anthropic API key with 1Password-backed secrets.
