Build Mini Event Perplexity (2026)

An r/buildinpublic post launched Olivepress (mini-Perplexity for stocks). The pattern generalizes to event search.

Prerequisites

Scavio API key
LLM API key
5-15 venue source domains per city

Walkthrough

Step 1: Pin source list per city

Discipline = trust.

Text

// AnnArbor: theark.org, thelivery.com, umich.edu/events

Step 2: Per query: Scavio site-search across venue domains

Returns event candidates.

Text

// 'live music this weekend' → site-search across [theark.org, thelivery.com]

Step 3: Reddit signal layer

Community events the venue calendars miss.

Text

// scavio_search('reddit r/AnnArbor this weekend live music')

Step 4: LLM compose with citations

Each claim ends with [N].

Text

// LLM: 'Answer using ONLY events below. Each event ends with [N]. Sources: [...]'

Step 5: Chart as native tool call (optional)

Visualize density.

Text

// Chart tool: { type: 'bar', data: events_per_night }

Step 6: Front-end: search + cited results + charts

Polished output > raw JSON.

JavaScript

// Next.js or Svelte: input → POST /api/ask → render LLM output with [N] citations + charts

Step 7: Validate with skeptical reviewer

Sanity check 20 queries.

Text

// 20 queries; verify each citation against source.

Python Example

Python

# Per-product-month MVP: $30 Scavio + ~$30-50 LLM = under $100/mo.

JavaScript Example

JavaScript

// Same shape in TS / Next.js.

Expected Output

JSON

City-events Perplexity-clone that pins to authoritative venue sources, fills the social gap via Reddit.
