It walks you through three short branching questions about common early methodology choices: review type, research approach and question framework. It shows the reasoning behind each fork.
Is the result a recommendation I should follow?
It is a starting point, never the final word. The helper structures the decision; the decision itself stays yours, ideally discussed with your supervisor.
Is this tool free?
Yes. It is part of the research-literacy layer of Bizarus, which stays free permanently. No account, no sign-up, no usage limit.
Does anything I answer leave my browser?
No. The helper loads its decision flows from a static file on the site; your answers are processed in your browser and never sent anywhere.
