For centuries, families have consulted masters to evaluate relationship compatibility before marriage.</p> <p>I built <strong>CeJi (测吉)</strong> to modernize this tradition — turning it into an accessible, AI-powered web experience that focuses on actionable insights rather than superstition.</p> <h2> What CeJi Does </h2> <p>Visit <a href="https://lucksol.com/" rel="noopener noreferrer">lucksol.com</a> and enter two people's birth information. Here's what you get:</p> <h3> 🆓 Free Quick Report </h3> <ul> <li>Overall compatibility score</li> <li> <strong>5-dimension analysis</strong>: Attraction sources, Complementarity &amp; conflict points, Root conflict causes, Timing windows, Repair suggestions</li> <li>Basic destiny readings for both individuals</li> </ul> <h3> 📊 Deep Report (¥39 / ~$5.50) </h3> <ul> <li>8 detailed chapters covering relationship patterns, conflict roots, and a 3-year trajectory</li> <li>Actionable communication and boundary suggestions tailored to the couple's specific Bazi configuration</li> <li>Reports are saved in the user's personal center and accessible across devices</li> </ul> <h3> 🔗 Partner Invite Feature </h3> <p>Don't know your partner's exact birth time? Generate an invite link — they fill in their own details privately. No awkward questions needed.</p> <h3> 🏠 Master Chat (宅师问诊) </h3> <p>For follow-up questions: relationship timing, family pressure, home layout &amp; energy flow, workspace arrangement, and major life decisions.</p> <h2> Tech Stack </h2> <ul> <li> <strong>Frontend</strong>: Next.js with SSR — fast initial loads and SEO-friendly</li> <li> <strong>AI Layer</strong>: LLM-powered report generation with structured JSON output, ensuring consistent report quality</li> <li> <strong>Analytics</strong>: Full UTM tracking (source/medium/campaign/content) with page dwell time measurement</li> <li> <strong>Payments</strong>: Integrated payment gateway with credit points system and VIP memberships</li> <li> <strong>Auth</strong>: JWT-based authentication with report persistence and cross-device access</li> </ul> <h2> Design Philosophy </h2> <p>We deliberately position CeJi as <strong>"folk culture exploration"</strong> and <strong>"environmental psychology reference"</strong> — not fortune telling. Every report includes a clear disclaimer that it's reference material, not a substitute for professional advice.</p> <p>Key design principles:</p> <ul> <li>Reports must be <strong>readable, shareable, and reviewable</strong> </li> <li>Insights are grounded in <strong>communication advice</strong>, not mystical guarantees</li> <li>The free tier is <strong>genuinely useful</strong> — not a teaser with no substance</li> <li>User privacy is paramount — partner data is submitted directly by the partner</li> </ul> <h2> Business Model </h2> <ul> <li> <strong>Freemium</strong>: Free 5-dimension quick report → ¥39 (~$5.50) deep report</li> <li> <strong>Additional products</strong>: Annual/monthly destiny reports, VIP memberships, credit points</li> <li> <strong>Primary conversion goal (Phase 1)</strong>: Free report → ¥39 marriage compatibility deep report</li> </ul> <h2> Try It </h2> <p>👉 <strong><a href="https://lucksol.com/?utm_source=devto&amp;utm_medium=social&amp;utm_campaign=2026-05-marriage-launch&amp;utm_content=article-tech-stack" rel="noopener noreferrer">lucksol.com</a></strong></p> <p>I'd love feedback from this community on:</p> <ul> <li>The landing page UX and conversion flow</li> <li>Report content quality and depth</li> <li>Ideas for reaching a broader audience beyond the Chinese-speaking market</li> </ul> webdev nextjs ai startup 桂明 Tue, 12 May 2026 08:15:35 +0000 https://dev.to/yuanbanqian3456/test-ceji-401p https://dev.to/yuanbanqian3456/test-ceji-401p <p>test <a href="https://lucksol.com" rel="noopener noreferrer">lucksol.com</a></p> webdev
