"It was night and day from one batch to another, adoption went from single digits to over 80%. It just spread like wildfire, all the best analysts were using Calcbird."

"The most useful forecasting tool that I currently pay for, hands down, is Calcbird. It's fast, autocompletes when and where you need it to, handles dependencies properly, sensible keyboard shortcuts, everything is well put together."

"The best forecasting applications have an autonomy slider: you control how much independence to give the model. In Calcbird, you can do scenario completion, targeted edits, or you can let it rip with the full autonomy agentic version."
