One cart for the entire internet
The Cart is a browser extension that unifies shopping across retailers into one compliant, wallet-first checkout flow. We don’t process payments — we streamline checkout.
The big idea: give the user one unified experience without crossing into processor/compliance territory.
How it works
- Add items from any site into one cart
- Review everything in a single confirmation screen
- Run checkout in sequence — the extension autofills and pauses only for required wallet/site confirmations
It’s not “one click total.” It’s one unified flow: start once, then lightweight confirmations per merchant/wallet as required.
What it provides
- Unified cart: save items from multiple retailers in one place
- Checkout runner: guided, site-by-site completion
- Order tracking: one dashboard across stores
- Price tracking: alerts + history over time
- Discount support: surface/apply codes where allowed
- Affiliate/referral: optional monetization layer
Even before checkout automation, the cart + tracking + price alerts are valuable daily utility.
Why users care
- Less chaos: stop losing items across tabs and carts
- Less friction: fewer repeated forms and logins
- More confidence: compare prices and track drops
- More control: approvals stay with the user/wallet
The Cart feels like one shopping experience even though purchases still happen on individual merchant sites.
Why now
- Shopping is more fragmented (marketplaces + DTC + social commerce)
- Wallet coverage is mainstream (Apple Pay / Google Pay / PayPal / Shop Pay)
- Autofill + field detection is finally reliable enough to scale
The timing supports a compliant “orchestration” layer without becoming a payment company.
Roadmap
Phase 1 — MVP (Organize + Compare)
- Browser extension: save items from 3–4 retailers into one cart
- Pull price + shipping estimates where available
- Price tracking + alerts (watchlist)
- Early monetization: affiliate links (optional)
Goal: prove retention and that users want a “single source of truth” for shopping — before touching checkout complexity.
Phase 2 — Overlay Checkout Runner (Unified Flow)
- Single confirmation screen (“Start checkout” once in the extension)
- Checkout runner processes merchants in sequence
- Autofill shipping/contact fields + preferences
- Pause only when the merchant/wallet requires confirmation
- Auto-advance after confirmation to the next merchant
Goal: a unified experience while staying compliant — no storing/transmitting card data and no auto-submitting payments on the user’s behalf.
Phase 3 — Scale + Tracking + Deals
- Expand coverage toward the long tail (monitoring + quick fixes)
- Order tracking hub: shipments, returns, receipts
- Discount engine: surface/apply codes where allowed
- Partnerships: wallets, affiliates, and eventually merchants
Goal: turn utility into a platform with recurring usage and clear monetization.
Risks & how we handle them
- Legal/compliance: avoid “processor” behavior by not storing/transmitting sensitive payment data; rely on wallets/browser payment flows.
- Merchant variability: checkout flows differ and change — runner must be resilient and adaptable.
- Blocks/captcha: when automation fails, degrade gracefully to autofill + manual completion for that site.
- Misfires: safeguards against wrong info and double submissions; confirm steps clearly; run merchants one at a time.
