Compass

Inspiration

Bunq has existing travel features but they are limited. Furthermore, there doesn't exist a a single travel planner that has bank integration and ai.

What it does

You tell Compass your trip details and it splits your money into spending buckets (food, transport, etc.), tracks your bunq transactions, and answers questions like "can I afford dinner tonight?" using your uploads(audio, PDF, images) and transaction history as context windows.

How we built it

Chat interface connected to Claude AI, backed by bunq's Sandbox for real transaction data. Upload a receipt or flight PDF and it reads the details automatically. Voice recordings and audio files are also supported.

Challenges we ran into

bunq's SDK has authentication quirks that took time to untangle. Keeping the chat responsive while the AI processes files and runs multiple operations simultaneously was also difficult.

Accomplishments that we're proud of

The chat feels natural, you talk to it casually and it correctly updates your budget. The feature that detects when you're in a foreign country and prompts you to start a trip budget is a nice touch.

What we learned

That agentic apps need fallbacks and limits inside reasoning loops to assure more deterministic performance. Additionally, testing through evaluation proves to be crucial in a multimodal setting.
