SmartSpender turns your Danish bank statements into clear insights. Sync transactions, spot forgotten subscriptions, and get actionable advice to save money — all through conversation with Claude.
Bank statements are fragmented and hard to read. Subscriptions accumulate silently. Forgotten trials convert to paid plans. And there's no easy way to get a clear picture — let alone take action.
You: What subscriptions am I paying for?
Claude:
I found 18 active subscriptions totaling 1.847 kr/month:
Netflix — 149 kr/md
Spotify Family — 179 kr/md
Viaplay — 99 kr/md (ingen brug i 3 mdr.)
...15 mere
