Build in public 13/30: Silly AI prompt mistake

I was trying to figure out why logging my math habit with Xtreeks last night counted for today rather than yesterday.

We use AI to try and understand context and it misunderstood my sign off. Thankful for tools like Langfuse in this case to track issues down, annotate and improve the prompts. Braintrust is another similar tool, but switched to Langfuse since it’s open source.

This will be super helpful once we get past MVP as we rely on AI to do more to make it all feel automatic and magical.

Currently using Gemini 2.0 flash and pretty impressed with it. It’s also dirt cheap.
