What is Both Sides AI?
Both Sides AI is a free critical thinking tool that takes any topic, opinion, headline, or argument and generates three progressively deeper passes of arguments — both for and against it. Whether you're forming an opinion, preparing for a debate, writing an essay, or stress-testing an idea, this tool ensures you've considered the strongest version of every perspective.
The tool is inspired by a well-known pattern: ask an AI to help you build your argument for hours, feel convinced — then ask it to argue the opposite. The AI often demolishes your carefully constructed case. This is actually a feature, not a bug. Both Sides AI makes that process structured and immediate.
The Three Passes of Thinking
Initial Case
The surface-level arguments most informed people would make. Good for getting oriented but often insufficient on their own.
Deeper Analysis
Non-obvious, nuanced arguments. Second-order effects, historical precedents, psychological dimensions, and systemic impacts that most people overlook.
Steel-Man ★ Most Important
The absolute strongest version of the argument. What the best-informed, most rigorous advocate would say. If you can't address the steel-man, you haven't really engaged with the position.

Frequently Asked Questions
What is the Both Sides AI tool?
Both Sides AI is a free tool that generates three progressively stronger arguments both FOR and AGAINST any topic, opinion, or headline. It uses AI to build an Initial Case, Deeper Analysis, and Steel-Man argument for each side — helping you stress-test ideas and form better-informed opinions.
What is a 'steel-man' argument?
A steel-man (the opposite of a straw-man) is the strongest, most charitable version of an argument — presented as a brilliant, well-informed advocate would make it. It's the hardest version to dismiss, and reading it often reveals important truths even in positions you disagree with.
Can I use a news article URL?
Yes — paste any URL in the optional URL field and the tool will fetch the page content and use it to ground the arguments in that specific article or opinion piece.
Why argue both sides?
LLMs are extremely capable at arguing in almost any direction. Using them to argue only one side can create sycophantic, one-directional thinking. Deliberately asking for the opposite view reveals blind spots, strengthens your own position, or sometimes reveals the opposing view is actually more compelling.
Is this tool free?
Yes, Both Sides AI is completely free to use with no account required.
