You can build a scheduled personal property monitor, but not One Place: the value is the maintained real-estate corpus, crawler fleet, AI extraction, deduplication, image/semantic search, geo enrichment, and constant source upkeep across millions of listings.

the prompt

Build me a scheduled personal property monitoring agent, the honest consolation
build for One Place: it watches the sources I configure, it does not rebuild a
live nationwide real-estate index. Requirements:

- Node + Express + better-sqlite3 on localhost:4920, with a small web UI for saved
searches, matches, and lead notes.
- Saved searches live in SQLite: name, source URLs, natural-language criteria, hard
filters, cadence, email recipients, and last-run time.
- A node-cron runner wakes on each cadence, fetches configured source/search pages with
Playwright, and stores raw HTML snapshots for debugging.
- Send cleaned listing HTML to an LLM API key from .env and extract strict JSON: title,
price, currency, surface, rooms, location text, description, image URLs, source URL, and
confidence.
- Match each extracted listing against the saved search criteria with deterministic
filters first, then an LLM yes/no explanation for fuzzy preferences like renovation
potential or sea view.
- Store listings and match decisions in SQLite, dedupe by canonical URL first and fuzzy
title+price+surface+location second; keep price-change history.
- Email new matches via Resend or SMTP creds in .env, including the match reason, key
fields, source link, and unsubscribe/disable link for that saved search.
- Include an MCP server exposing tools: list_saved_searches, run_search_now,
get_recent_matches, explain_match, update_search, and add_lead_note, so Claude/Codex can
operate it from chat.
- No accounts, no telemetry, binds to localhost only. Out of scope: nationwide coverage,
anti-bot arms races, paid data resale, mobile apps, and collaborative CRM.
- README: crawler ethics, robots/terms warning, required API/email keys, how to run the
scheduler, and how to connect the MCP server.

why people still pay

They pay because property search is a moving data pipeline: portals block scrapers, listing HTML changes, duplicates multiply, and the useful part is having the whole market normalized and searchable before a deal disappears.

what you lose

xmillions of already-normalized listings

xmaintained crawlers across real-estate portals

xAI extraction, deduplication, and image/semantic search at scale

xgeo/POI enrichment and currency/unit normalization

xhosted boards, lead pipeline, sharing, and agentic search
