Murmur uses a small AI language model that runs directly in your browser — no data leaves your device. On mobile or slower devices, we fall back to a cloud-based model for speed. You give it a mood or topic, and it writes a modern haiku.

Modern/authentic haiku — short-long-short rhythm with a cutting moment (a surprise or shift). We don't enforce strict 5-7-5 syllable counts. Think urban, nerdy, everyday imagery.

We print on premium Bella+Canvas blanks — soft, durable, and ethically manufactured. Available in unisex, fitted, and relaxed cuts.

Each shirt is printed on demand after you order. Production takes 2-5 business days, plus shipping (3-7 days US, 7-14 days EU). You'll get tracking info via email.

Currently US and select EU countries (UK, Germany, France, Netherlands). We plan to expand to more countries soon.

Since each shirt is custom-printed, we can't accept returns for change of mind. If there's a defect in printing or the wrong item was sent, we'll replace it or refund you. Email us at hello@polgarp.com.

Absolutely. The haiku you generate are yours. Share them, print them, tattoo them — whatever feels right.
