Honest framing

A chat that preps the whole round — not a timed practice app

This isn't a formal debate-practice platform with a countdown clock or a judge's score sheet. @vustbot is a general multi-model AI chat that, across one conversation, builds your case, anticipates attacks, and runs a genuine question-and-answer cross-examination drill. There's no /prep command; you describe the motion, side and format and it adapts.

Evidence angles are reasoning, not sourced citations — verify anything you'll actually cite in round.

See the difference

A motion and format into @vustbot, the sized case and anticipated attacks that come back, then a live cross-ex drill.

A motion into a full prep sequence

What you send @vustbot

"I'm debating Lincoln-Douglas format, 6-minute constructive. Motion: 'Justice requires the recognition of animal rights.' I'm on the affirmative. Walk me through prep: case outline, likely negative attacks, and a cross-ex drill."

What comes back

A value/criterion framework for the affirmative case, 3 contentions with supporting warrants sized to fit a 6-minute constructive, the 3 attacks the negative is most likely to run (framework clash, a counter-value, a practical-harms turn), and then it offers to run the cross-ex drill live — asking you the hostile questions a negative debater would, one at a time, so you practice answering under pressure instead of just reading a script.

Drill the weak spot

Follow-up in the same chat

"Run the cross-ex drill now. Start with the framework attack."

What comes back

It asks the actual hostile question ("Doesn't your criterion collapse if we can't verify animal suffering the way we verify human suffering?"), waits for your answer, then tells you plainly whether that answer would hold up or gives you a stronger one — a real practice loop inside the chat, not a static script to memorize.

02·Practical use cases

Who needs full round prep, not just arguments

Competitive debaters

You know your motion, side and format, and need to walk into the round ready

Get a case outline sized to your speech time, the opponent's likely attacks, and a live cross-examination drill in the same chat.

Students prepping Model UN or class debate

You're new to formal debate structure and don't know how to pace a case

Tell @vustbot the format and time limits; it shapes speech-length material and points of information so the structure isn't guesswork.

Anyone practicing for a hostile Q&A

You're prepping for something debate-adjacent — a defense, a hard meeting, a panel

Use the cross-examination drill format on your own material: it asks real hostile questions and tells you if your answer holds.

03·How it works

How the round prep runs in chat

02Get a sized case and anticipated attacks

It builds your case with warrants sized to your speech time, then names the attacks the opponent is most likely to run against it.

03Run the live cross-ex drill

Ask it to drill you — it asks real hostile questions one at a time, waits for your answer, and tells you honestly whether it would hold up.

05·Quality & trust

Honest scope — full prep in chat, not a timed practice platform

General AI chat, not a scored round simulator

@vustbot doesn't run a formal timed environment with a judge's score sheet. It does the actual prep work — case-building, attack anticipation, live cross-ex — as a real conversation you steer.

Evidence angles, not citations

It reasons from training to build supporting angles and can state something confidently that needs checking. Verify any statistic you'll actually cite in round, or ask @vustSearchBot for sourced answers.
