Weekend trip from Berlin
Cheap, nearby, good weather
Thinker
I need a cheap weekend trip from Berlin next month. Somewhere with decent weather and direct train access. Help me pick one and outline the plan.
Thinking
Dresden looks strong for this: 2 hours by direct IC train, hotel options under 50 euros a night, and May averages 19 degrees. The old town, Zwinger Palace, and a day hike in Saxon Switzerland are all doable in a weekend.

Key Insights

Here's a quick breakdown of what matters most:

  • Shipping is the biggest bottleneck right now
  • Customer retention drops after week 3
  • Q4 push should focus on referral incentives
analyzeMetrics.py
python
def find_bottlenecks(metrics):
shipping_delay = avg(metrics.shipping_times)
retention = cohort_retention(weeks=3)
return {shipping_delay, retention}

Browsing

Open websites and inspect sources inline

Website viewing deserves its own feature story. It is different from search: once Lumy finds something, it can step into the source and surface what matters.

I tightened the hero and moved the detailed feature storytelling into alternating sections so the first screen feels lighter and more premium.
