An argument map lays out the reasoning around a question as a structured set of arguments for and against a claim, instead of a linear discussion thread. To make one, start with a question that can be argued both ways (for example, "Should we adopt a four-day work week?"), then add the strongest supporting arguments as pros and the strongest objections as cons, one point per entry. This free argument mapping tool runs client-side and requires no account. The full Argumentree app extends the same idea with AI argument extraction from meeting transcripts and documents, real-time team collaboration, and participant rating so consensus is measured as net pro/con support — but the on-page maker itself works with no signup.
Build a pro/con argument map in seconds. Type a question, add the arguments for and against, and copy it as a clean outline. Free, no signup — it all runs in your browser.

An argument map turns a messy debate into a structure you can actually reason about: the question at the top, and the case for and against it laid out side by side. Here's the workflow the maker above follows.
Write a question or thesis that can genuinely be argued both ways — "Should we adopt a four-day work week?" rather than "the four-day week". A sharp question keeps every argument below it on-topic.
List the best arguments in favor as pros and the best objections as cons — one distinct point per entry, kept short. Resist merging two ideas into one line; separate points are easier to weigh and, later, to respond to individually.
With pros and cons side by side, gaps become obvious — a con with no answering pro, or a pro that rests on an unstated assumption. That's the payoff of mapping over threading: you see the whole case at once. Use "Copy as text" to drop the outline into a doc, ticket, or message.
A flat pro/con list is the starting point. Bigger decisions need sub-arguments (reasons behind reasons), evidence, and a way to weigh which points carry more support. For a fuller treatment of the method, see what is argument mapping and the roundup of the best argument mapping software.
An argument map is a visual outline of the reasoning around a question or claim. It puts the central question at the top, then lays out the arguments for it (pros) and against it (cons) so you can see the whole case at a glance instead of losing it in a conversation thread. Mapping the reasoning this way makes hidden assumptions and weak links easier to spot.
Start with a clear question or thesis — something that can be argued for or against, like "Should we adopt a four-day work week?" Then add the strongest arguments in favor as pros and the strongest objections as cons, one point per entry. Keep each point short and self-contained. The maker on this page does exactly that: type your question, add pros and cons, and it renders a two-column pro/con map you can copy as a text outline.
Yes. The tool on this page is completely free and runs entirely in your browser — there is no signup, no account, and nothing is sent to a server. You can build a pro/con map and copy it as text without creating an account. The full Argumentree app, which adds AI extraction, real-time collaboration, and rating, offers a free tier plus paid plans for teams.
The simple maker on this page is manual — you enter the pros and cons yourself. The full Argumentree app can extract arguments automatically from meeting transcripts and documents with AI, turning a raw discussion into a structured pro/con tree. It also lets a whole team collaborate in real time and rate arguments so the group's consensus is measured as net support.
A mind map is a free-form web of associated ideas branching out from a central topic — it captures what you're thinking about. An argument map is stricter: every node is a claim, and every connection is a reason for or against another claim. It captures whether an idea is well-supported, not just that it exists, which is why it's better suited to weighing a decision.
This maker is yours to use free, no signup. When a decision involves your whole team, the full Argumentree app adds AI extraction from transcripts and documents, real-time collaboration, and argument rating so consensus is measured as net support — with a full audit trail of how you decided.
