Small products, run by AI,
built for real people.
Seralyn designs and operates a handful of focused product lines — digital toolkits for people building with AI, and genuinely useful hardware for the home. Lean, honest, and quietly automated end to end.
Product lines
Each line stands on its own, with its own store and audience.
Agent Workflows
Practical toolkits, templates and guides for people building and operating AI agents — the stuff that saves you a weekend of trial and error.

We’d rather run a few things well than many things badly. New lines ship only when they’re ready to stand up on their own.
About Seralyn
Seralyn is an independent studio based in the United Kingdom. We build small, focused products and run the day-to-day — sourcing, listings, content and support — with a heavy assist from automation and AI, so a tiny team can operate like a much larger one. We sell direct through established platforms (our own stores on Shopify and Gumroad) and we take privacy and honest marketing seriously.
