🧠 Polyground — Calm, AI-Driven Polymarket Tracking

🌟 Inspiration

We wanted a calmer way to track Polymarket without the constant tab-hopping and noise. So we built Polyground, a “set it and forget it” scout that pins markets, monitors probability shifts, and surfaces Claude’s insights — only when the math actually changes.

---

⚙️ What It Does

Polyground brings together a dashboard and browser extension that let you:

• 📌 Pin markets via URL, ID, or slug — directly from Polymarket.
• 📊 View implied probabilities, deltas, and sparklines for quick at-a-glance insight.
• 🔍 Jump straight into detailed market pages with one click.
• 🧠 Receive Claude-authored alerts summarizing significant moves.
• 🔔 Unread badges stay in sync across all views.
• 🧹 Bulk actions — select all, delete, or mark as seen — for effortless portfolio cleanup.

---

🏠 How We Built It

Frontend:

• ⚛️ React + Vite + TanStack Query
• ♻️ Shared UI components between dashboard and extension
• 📈 Lightweight sparkline and metric card system

Backend:

• 🚀 FastAPI + SQLAlchemy
• 🔁 Worker process polling Polymarket snapshots
• 🤖 Claude-powered insight generation
• 🌐 REST endpoints serving both clients

State Resilience:

• 💨 Optimistic updates with mock fallbacks
• 🤩 Instant, smooth UX even if backend lags

---

🧩 Challenges We Ran Into

• 🔍 Normalizing every possible “pin” input (IDs, slugs, URLs) across both popup and dashboard.
• ⏱️ Maintaining a real-time feel with a polling backend — solved using optimistic caching and granular mutation hooks.
• 🤭 Designing bulk actions that are powerful yet accessible (select-all, delete, focus states).

---

🌿 Accomplishments We’re Proud Of

• ✅ Unified pin experience: identical validation and messaging across clients.
• ♿ Accessible bulk management: select-all checkbox, delete icon, and per-card mark-as-seen all keep unread counts perfectly synced.
• 💬 Claude insights that feel human: clear, actionable commentary instead of raw numbers.

---

💡 What We Learned

• 🧱 Treating mock mode as a first-class path sped up iteration while backend plumbing evolved.
• 🎨 Small UX touches — status pills, inline toolbars, focus outlines — dramatically improve polish.
• ⚡ Writing optimistic mutations with rollbacks builds user trust through consistent, instant feedback.

---

🚀 What’s Next for Polyground

• 🌂 Auto-tag + cluster alerts to filter by theme or volatility.
• 📣 Push, email, or Discord notifications for high-severity moves (Δ > 10%).
• 🤝 Collaborative watchlists — share pinned markets, annotate alerts, and compare conviction forecasts (P(event)) across teams.

Polyground — your calm, intelligent companion for Polymarket tracking.
