Words from the Masters
Wisdom about public speaking from history's greatest communicators
"According to most studies, people's number one fear is public speaking. Number two is death. Death is number two. Does that sound right? That means that if you're at a funeral, the average person would rather be in the casket than giving the eulogy."
— Jerry Seinfeld
"It usually takes me more than three weeks to prepare a good impromptu speech."
— Mark Twain
"The human brain is a wonderful thing. It starts working the moment you are born and never stops until you stand up to speak in public."
— George Jessel
"Be yourself; everyone else is already taken. And if you can't, at least give a good speech pretending you are."
— Oscar Wilde
"If it is not right, do not say it. If it is not true, do not say it."
— Marcus Aurelius
"To be ignorant of what occurred before you were born is to remain always a child. To speak well is to live twice."
— Cicero
"To teach how to live without certainty, and yet without being paralyzed by hesitation, is perhaps the chief thing that philosophy can do. Public speaking is no different."
— Bertrand Russell
"Courage is what it takes to stand up and speak; courage is also what it takes to sit down and listen."
— Winston Churchill
"Speech is power: speech is to persuade, to convert, to compel."
— Ralph Waldo Emerson
"There are always three speeches, for every one you actually gave. The one you practiced, the one you gave, and the one you wish you gave."
— Dale Carnegie
"A good speech should be like a woman's skirt: long enough to cover the subject and short enough to create interest."
— Winston Churchill
"There are only two types of speakers in the world. 1. The nervous and 2. Liars."
— Mark Twain
"The right word may be effective, but no word was ever as effective as a rightly timed pause."
— Mark Twain
"Speak, so that I may see you."
— Socrates
"Words are, of course, the most powerful drug used by mankind."
— Rudyard Kipling
"The success of your presentation will be judged not by the knowledge you send but by what the listener receives."
— Lilly Walters
"All great speakers were bad speakers at first."
— Ralph Waldo Emerson
"If you can't explain it simply, you don't understand it well enough."
— Albert Einstein
"The most precious things in speech are the pauses."
— Ralph Richardson

Built by Coaches
KouLi blends real-world coaching expertise with AI to help people perform under pressure.
Nahdia Khan
Nahdia Khan is an executive coach and leadership development specialist with 20 years' experience helping senior leaders perform when it matters most, including board presentations, investor conversations, and high-stakes negotiations. Through her work leading insight and impact at global leadership organisations, she's seen first-hand why most communication training fails to stick ... and what actually builds confidence under pressure. KouLi reflects that insight: confidence isn't built by consuming content or chasing scores, but through practice, coaching, and reinforcement over time.
Emma Blackery
Emma Blackery brings a grounded corporate perspective shaped by hands-on experience advising boards, coaching leaders, and supporting early-stage founders. She understands where confidence most often falters as careers progress, particularly around visibility, expectation, and high-stakes communication in complex organisations. At KouLi, Emma helps ensure the product supports real growth rather than adding pressure, keeping the use of AI practical, thoughtful, and genuinely helpful in real working lives.
Adam Chalmers
Adam Chalmers is the founder of KouLi. He has spent over a decade teaching, coaching, and closely observing how people speak under pressure, whether in interviews, presentations, or high-stakes professional settings. Across thousands of hours of listening and feedback, Adam kept seeing the same patterns: people don't struggle because they lack ideas, but because pressure changes how they speak ... clarity drops, confidence wavers, and structure falls away. KouLi was built to make high-quality speaking practice and coaching available at scale, combining real-world communication insight with AI to help people improve through repetition, reflection, and guided feedback, not scripts or scores.

My pitch structure improved a lot after using this. The feedback was specific enough to actually fix things.
