Quick poll for founders (and anyone who tests out new SaaS tools): do you ask for a credit card upfront, or let people straight in?

We went with requiring a card for k dlo. The thinking was pretty simple: fewer signups overall, but higher intent people actually kick the tires instead of bouncing after two minutes. Without a card, you get a flood of accounts that log in once and ghost.

But I m genuinely torn here. A card wall definitely kills casual curiosity, especially when you're an unknown product. On the flip side, no-card trials often just give you vanity metrics that don't convert.

Two quick questions:

I recently saw a reel where a girl was recording a Skill with Claude to find newly posted real-estate apartments every day.

She had specific filters - location, price, etc. and Claude would go through the new listings, find the ones that matched, collect all the relevant information, and create a spreadsheet with the results every day.

Prompt engineering has changed a lot recently. I remember around this time last year, strict prompt engineering rules were a must. From You are a professional persona setting, to zero-shot, few-shot CoT techniques, these were necessary for quality outputs

Nowadays, it feels as if AI models do the engineering all by themselves without user input. They understand us well even if we re just casually typing (some call it lazy prompting , and I even saw a product related to this on PH)
