# Perennial

> Perennial (perennial.you) sells a one-time digital product: a personalised **Communication Fingerprint** — a Markdown system prompt plus an implementation guide — built from a structured questionnaire. Payment is via Creem; delivery is by email within 48 hours of questionnaire submission.

## About

Perennial helps people deploy AI assistants that sound like them. Customers choose a fidelity level (L1–L3), complete a questionnaire (typically 35–105 minutes depending on level), and receive a `.md` system prompt and deployment guide. The recommended daily path is **Perennial Echo** (free desktop app at `/echo`); the PDF guide also covers Claude, GPT, Grok, and local models as secondary options. There is no subscription for the fingerprint deliverable.
