How Kantoku works
Interrogative coaching
"Have you considered the counterargument?" not "Here's a better sentence." Kantoku's AI reads your writing and asks questions that help you think more clearly, identify gaps, and strengthen your argument. It never suggests text, never inserts fragments, never rewrites your prose.
Markdown & LaTeX native
Write equations, citations, and structured documents in the formats academia already uses. No fighting with a word processor. First-class support for the tools researchers actually need.
Git-based provenance
Every change is tracked. Full version history of your document's evolution. In an era where "did AI write this?" is the wrong question, Kantoku lets you show how your document was written. Essential for academic integrity.
