JustilityArgument mapping canvas
Connect claims, evidence and objections in an editable local argument map.
Map claims, evidence and objections. Connect a source node to the claim it supports or challenges.
Up to 40 nodes and 80 connections on a 1200 × 900 canvas. Edit all content using the fields. Focus a diagram node and use arrow keys to move it (Shift = 30 units); dragging also works. Visual maps describe your model, not verified causation.
Your work stays in this tab. Nothing is saved automatically. Save a readable, unencrypted project file before closing. Downloads remain wherever you save them.

How privacy worksHow it works
Open argument mapping canvas, enter your own project details or load the labeled example, then edit nodes and connections and analyze the map. Review the results and download your project to continue later.
Supported formats
Editable JSON project up to 1 MB; SVG diagram and CSV analysis. Up to 40 nodes, 80 links, 120 characters per label and 1,200 per note.
Good to know
Arguments and sources are entered manually; truth and logical validity are not automatically assessed.
Worked example
Before
Claim: extend library hours; evidence: measured evening demand; objection: staffing costs
After
Two directed relationships record support and challenge
The map records reasons and sources without automatically judging whether a claim is true.
Argument mapping canvas: interpret the result
Connect claims, evidence and objections in an editable local argument map. Arguments and sources are entered manually; truth and logical validity are not automatically assessed. All project files are readable and unencrypted. Save and open them explicitly; there is no automatic browser persistence.
Second-order thinkingTroubleshooting
Does a support link prove my argument?
No. A link records your reasoning. Evaluate source quality, relevance, missing premises and possible circular support separately.
Common questions
Can I use argument mapping canvas offline?
Prepare this tool using Offline help while online. After preparation, it runs locally with fresh input. Browser cache eviction remains possible; keep project downloads separately.
Can I use this without an internet connection?
Yes, after you prepare this tool from Offline help and the browser retains its assets. Installation is optional. All processing dependencies are bundled locally.
