How do you memorize what you need to say before a big presentation or pitch?

I've been asking this question to everyone I know who presents regularly — founders pitching investors, salespeople doing demos, speakers at conferences.

The answers fall into roughly three camps:

1. "I just wing it" — rely on experience and bullet points
2. "I rehearse out loud over and over" — repetition until it sticks
3. "I read from a script" — safe but often looks robotic

None of these feel great. Winging it is stressful. Rote repetition is boring. Reading kills eye contact.

I got so frustrated with this that I ended up building a tool to solve it — an AI that gradually fades your script over a week of practice so you learn to speak from memory naturally (tryoffscript.com if curious).

But genuinely curious: how do YOU prepare for high-stakes presentations? What's your actual process?

Have you ever blanked mid-presentation? What happened?
