Debate Case Builder: Write a Case Step by Step
A debate case builder is a tool that walks you through writing a case in parts (contentions, framework, rebuttal blocks, cross-ex questions) and checks each part as you write it. The Case Builder on The Debate Prep tests every argument against assertion, reasoning, evidence and impact, so you find a weak warrant before building more on top of it.
What a case builder should do for you
Break the case into parts
An introduction, an argument and a conclusion each have a different job. A tool that treats them all as one block of text cannot tell you what is missing.
Check while you write
Reviewing a finished draft once means the weak parts survive every earlier version. Checking as you go catches them early.
Explain, do not just score
A number tells you nothing about how to improve. Look for the reason a part is weak and a fix you can make in your own words.
Fit your format
A Lincoln-Douglas value criterion and a Public Forum contention are different things. The structure should change with the format.
Keep the writing yours
The goal is to get better at building cases. A tool that writes the case for you does not help when you are on the clock in a round.
How the Case Builder works
- Cases are built in parts: contentions, framework, rebuttal blocks and cross-ex questions.
- Each argument is tested against assertion, reasoning, evidence and impact (AREI).
- Weighing is written with sentence starters and checked for whether it compares both sides.
- Fix a note in your own words and check again to see the score change.
- Parts can be assembled into one speech in the speech assembler.

Frequently asked questions
How do I write a debate case?
State your claim in one sentence, then back each contention with an assertion, the reasoning behind it, evidence and the impact. Add framework if your format uses it, then write the rebuttal blocks you expect to need.
Does the Case Builder write the case for me?
No. You write it, and the tool checks each part and explains what to fix. That keeps the skill yours for the round itself.
What is AREI?
Assertion, reasoning, evidence and impact: the four pieces every argument needs. If one is missing, an opponent can find the gap in cross-ex before you do.
Which formats can I build a case for?
Every supported format, including Public Forum, Lincoln-Douglas, Policy, World Schools and the parliamentary formats.
