๐Ÿ“ About the Project
๐Ÿ’ก Inspiration
Haggling on Carousell is a WAR CRIME against your sanity. Lowballers ghosting you, boomers yelling "FIRM PRICE LAH," and sellers who think S$1.2k for a scratched iPhone 12 is "BNIB." We said ENOUGH. Channeling Chris Voss's Never Split the Difference, we birthed cheapskate.aiโ€”the negotiation bot that haggles harder than your auntie at wet market.

๐Ÿค– What it does
cheapskate.ai: Your personal Carousell chaos manager that turns "WAHHH TOO EXPENSIVE LA" into "OK LAH S$XXX can?"

  • Search & Snipe: Finds your dream iPhone 15 under S$1k while you Netflix & chill
  • Auto-Haggle: Deploys Ackerman model + Voss mind games = sellers crying into their teh tarik
  • Mission Control: Tauri dashboard with 3FPS live stream (yes it looks like 240p YouTube but SHH)
  • 24/7 Stalker Mode: Watchdog sniffs new message badges like a desperate Tinder user
  • Memory Like Elephant: Reads chat history so it NEVER asks "Still selling?" after seller says "SOLD"

๐Ÿ—๏ธ How we built it

  • ๐Ÿง  The Brain: Playwright puppeteering Chrome + Ollama/Gemini LLMs whispering sweet nothings (lowballs). Chat directly with agent via Gemini API!
  • ๐Ÿซ€ The Heart: Python Bridge Server (aka "Why won't frontend talk to backend HELP")
  • ๐ŸŽจ The Glow-up: React+Tauri with glassmorphism so shiny your eyes water
  • ๐Ÿ•ต๏ธ Stealth Mode: JS injection to hide webdriver fingerprints (we're basically browser spies now)

๐Ÿšง Challenges we ran into

  • "Flushed" Viewport: Playwright's fixed window size made Carousell layout explode like bad ayam penyet
  • Flickering Hell: Live stream looked like Japanese horror film. Fixed with "Atomic Moveโ„ข" file swaps
  • Context Amnesia: LLM kept forgetting chat history like your ex. Built Smart Syncโ„ข DOM reader
  • Auth Nightmare: Sessions timing out mid-haggle = AUTOMATION DEATH. Saved cookies locally + 2FA token magic

๐Ÿ† Flexes we're proud of

  • 100% Hands-Free: Spots message โ†’ inbox โ†’ haggle โ†’ profit. Your only job: count savings
  • Aesthetics: Dashboard so clean Elon Musk would recruit us for Dogecoin
  • Voss Magic: Bot drops "Seems like you're firm on price?" and sellers actually BUDGE

๐ŸŽ“ What we learned
Browser automation = 90% waiting for loading spinners, 10% copy-pasting selectors. Tauri = web devs finally escape Electron bloat. Patience > code.

๐Ÿ”ฎ Next Level Chaos

  • Facebook Marketplace (let the boomers FEEL our power)
  • AI voice calling sellers at 2AM ("Bro still awake? S$50 how?")
  • Rage detection so bot knows when to ghost angry uncles
