This is a submission for the Algolia Agent Studio Challenge: Consumer-Facing Non-Conversational Experiences

𝗖𝗮𝘁𝗲𝗴𝗼𝗿𝘆 𝗦𝘂𝗯𝗺𝗶𝘀𝘀𝗶𝗼𝗻: Consumer-Facing Non-Conversational Experiences

Challenge Prompt Fit: This project is intentionally submitted as a Consumer-Facing Non-Conversational Experience. It enhances investor workflows proactively through search, divergence detection, and contextual retrieval without requiring a chat-first interface.

What we built 🤔

Red Flare is an AI-powered divergence detection platform for retail investors.

Institutional desks use expensive terminals to detect valuation, debt, and sentiment anomalies in real time. Retail investors usually discover risk too late. Red Flare closes that gap with fast search, NLP filters, historical pattern matching, and AI-assisted risk analysis for NIFTY 500 and Nasdaq 100 stocks .

How it works? 💣

Users search stocks naturally using phrases like high debt banks, overvalued tech, or even typo queries like Relience.

The app combines:

Algolia Search + Query Rules + Synonyms for instant discovery
Algolia Agent Studio across 4 indices for contextual AI analysis
Yahoo Finance for live market enrichment
Upstash Redis for cached AI responses and lower latency

Flow:

User searches or opens a stock
/api/stock fetches quote + fundamentals and enriches with Algolia metadata
/api/news computes sentiment from recent headlines
/api/analyze detects divergences, computes risk score, queries patterns/scandals, then streams AI output
Result is cached in Redis for 6 hours for repeat access

Why Algolia Agent Studio?

Search quality and retrieval speed are core to this product.

Algolia gives us low-latency discovery, robust typo tolerance, rules-based intent parsing, and a clean path to RAG through Agent Studio. We can ground AI outputs using multiple indices instead of generating generic commentary.

const agentResponse = await fetch(agentUrl, {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "x-algolia-application-id": appId,
    "x-algolia-api-key": apiKey,
  },
  body: JSON.stringify({
    messages: [{ role: "user", parts: [{ type: "text", text: context }] }],
    stream: true,
  }),
})

Additional Algolia usage:

Query Rules for intent shortcuts (high debt, risky, banks, etc.)
Synonyms for finance vocabulary normalization
Custom ranking for market-cap-prioritized relevance

ㅤ

Caching Layer (Upstash Redis) ⚡

To prevent repeated expensive generation and improve UX, we cache completed analyses per symbol/day:

const CACHE_TTL_SECONDS = 6 * 60 * 60
const key = `redflare:analysis:${symbol}:${date}`

This gives fast repeat loads while keeping data fresh.

ㅤ

Design 🎨

The UI is intentionally terminal-inspired with a high-signal visual style:

dark market-console aesthetic
compact data-dense cards
animated but restrained interactions
emphasis on quick scanning of risk and divergence indicators

Design goal: make analysis feel immediate, not overwhelming.

ㅤ

Challenges we ran into 😤

Getting robust fallback behavior when external AI providers timeout or hit quota
Balancing fast streaming UX with deterministic fallback output
Keeping search intent parsing precise across mixed AND/OR financial filters
Preserving responsiveness while rendering dense analytics cards and charts

ㅤ

What’s next? 🚀

User auth + per-user watchlists
Alerting on divergence threshold changes
Better abuse protection on analysis endpoints
Sector-level heatmaps and multi-stock compare view
Expanded historical event intelligence and explainability

End Notes 🙌🏻

Thanks to the hackathon organizers and the Algolia ecosystem for the tooling that made this possible.
