Unprompted guides
These English pages share one loop: draw a topic you did not pick, work inside a timer, explain the idea in your own words, and review one problem. Use a product playbook when you want the format. Use a skill guide when you want a speaking habit to practice on the same tool.

Use these when you want the rules for a one-minute round or a source-based round. They describe the product loop, not a speaking-habit search.
How to Do the Unprompted Challenge
Draw a topic you did not choose, work within a fixed preparation window, and explain one clear idea aloud. This guide gives the Unprompted challenge a practical set of rules, several useful formats, and a review method you can repeat on your own.
How the Unprompted Deep Research Challenge Works
A random topic can become a focused learning round when the research question, source choices, notes, and explanation each have a clear job. This guide shows how to learn within a time limit without confusing speed, the amount of material collected, or fluent delivery with understanding.
Speaking-skill guides
Use these when you searched for how to speak clearly, how to become more articulate, or how to reduce filler words. Each page teaches one habit you can practice without the brand, then offers a random topic if you want one.
How to Speak Clearly
If people ask you to repeat a word, record a familiar sentence, mark the spot they miss, and say the same words again with only that change.
How to Become More Articulate
If you tend to give the background before the answer, reverse the order. State your point in one sentence, then add a reason and a concrete example.
How to Reduce Filler Words When Speaking
When you feel um coming, close your mouth and pause. Record the same answer twice so you can tell a real drop in fillers from a shorter take.
