CapitalCurveMoney in. Money out.All in one place.
The only expense tracker with AI Smart Paste, share-to-import, shared-account splits and CSV bank imports — built to survive lazy weeks.
What makes it different
Not your typical expense tracker.
The stuff most apps skip — and the reason a lazy week doesn't blow up your budget.
Smart Paste, powered by AI
Paste any bank SMS, push notification or receipt email — AI pulls out amount, merchant, date and category. No typing.
Share bank alerts straight to the app
On Android and Chrome, hit Share on any bank message — it lands in Smart Paste, pre-filled. Zero copy-paste.
Shared accounts with per-person split
Track who paid on a shared card or rent. Monthly breakdown per member — end the "who owes who" debate.
CSV bank import
Drop last week's export from your bank. Auto-detects date, amount and description columns. Whole week in 30 seconds.
Recurring on autopilot
Rent, salary, Netflix — set once, weekly or monthly. Created automatically on the right day, even if you skipped a week.
PDF & CSV reports
One click for a clean PDF report with totals, or CSV for your spreadsheet. Great for taxes and expense claims.
Security & privacy
Your data is safe.
Boring, careful engineering — so your money data stays yours.
Enterprise-grade hosting
Data lives in a managed PostgreSQL database on Supabase, a SOC 2 Type II certified platform.
Passwords never in plain text
Authentication is handled by Supabase Auth — passwords are hashed, never stored as readable text.
No bank login, ever
CapitalCurve never connects to your bank. Smart Paste only reads text you paste or share yourself.
Never sold, never shared
Your transactions are not sold, rented or shared with third parties — not now, not later.
