FatePreview
Explore your options before a big life decision.
What is FatePreview?
FatePreview is a deterministic decision comparison tool using fixed planning rules for people facing a concrete life choice.
Instead of pretending to predict what will happen, FatePreview helps you compare possible paths, examine their trade-offs and constraints, identify important assumptions, and find smaller actions you can test before making a larger commitment.
Its first English decision experience focuses on a common question: whether to leave a job and start a business. Users can compare staying employed while preparing, testing the business on the side, and leaving to build full-time based on their current situation.
FatePreview is currently available as a free beta.
The English comparison uses three routes, explicit input facts and assumptions, trade-offs, and seven-day experiments. No account is required, there is no charge, and results are not saved to an account.

you need to get more scientific with something that's going to be in production and that could be as simple as you know just running that prompt like 30 times um and then pasting it into Google doc right um and and then just reviewing like okay like how often does it do bad things
Run the prompt 100 times in async, then review the failures
Running a prompt once and shipping it is the prompt-engineering equivalent of medieval bloodletting — a lucky hit mistaken for a working system. Before any prompt goes into production, run it 30-100 times asynchronously, dump outputs into a doc, and cluster the failures. Bulk review surfaces real failure modes instead of the one good output that tricked you.
With annual subscriptions you might not really understand just how bad your retention is until 12 months later... you're getting people who are willing to pay money to try it out but then don't retain, and so you're getting a lot of mixed signals.
Hard Paywalls Mask Bad Retention — Annual Subs Hide Churn For 12 Months
Jeff Morris's core warning for founders using hard paywalls: annual subscriptions create a 12-month blind spot where churn is invisible. You collect revenue from people who won't renew, mistake it for product-market fit, and only discover the damage a year later. Engagement and retention signals, not early revenue, tell the real story.
There's a play for whatever you're stuck on.
