SmartSplit

Snap the receipt. Keep the memory.

Mobile-first React SPA. One photo → AI-parsed items → per-item × per-person split → settled tab pinned to a place.

Run

npm install
cp .env.example .env.local   # paste your MiniMax key (optional)
npm run dev

Dev server: http://localhost:5173 — open it on your phone (same wifi) for the real demo flow.

Capture uses a two-stage pipeline:

1. Tesseract.js runs locally in the browser → raw OCR text from the receipt photo.
2. MiniMax-M2.7 (text-only chat) structures that raw text into JSON items.

Without a MiniMax key, stage 2 falls back to a regex-based local parser; if you also don't take a photo, the app uses a built-in sample receipt. Either way the rest of the flow works.

Why this pipeline? MiniMax's chat models are text-only, so vision stays in the browser and the LLM does the semantic heavy lifting. This also doubles as the "parallel agents" talking point in the deck — pixels and language are handled by specialist agents in parallel.

Pitch flow (also the user flow)

#	Route	What the audience sees
1	/	Problem framing + memory timeline
2	/capture	Real photo → MiniMax → itemised list in seconds
3	/squad	Pick who participated
4	/allocate	Tap who had each item (the differentiator)
5	/settle	Final amounts, pinned to a place, saved to memory

The PitchStrip at the top makes the step you're on obvious during a live pitch.

Architecture

src/
  main.tsx           — entry, wraps app in <StoreProvider>
  App.tsx            — routes
  components/        — TopBar, PitchStrip
  routes/            — Home, Capture, Squad, Allocate, Settle
  lib/
    types.ts         — domain types
    split.ts         — pure integer-cent split math
    storage.tsx      — React Context + localStorage persistence
    minimax.ts       — vision API client w/ sample fallback
  styles/theme.css   — single CSS file, cream/coral/teal palette

State lives in one React Context (useStore), persisted to localStorage on every change. No backend.

Why this is different from Splitwise

• Splitwise: type every line item by hand. We: one shutter click.
• Splitwise: flat balances. We: per-item × per-person ledger, integer cents.
• Splitwise: money math only. We: every receipt is a place + time on a shared memory timeline.
