Your debate prep,
finally intelligent.
Backfile is the AI assistant that reads your files, understands your arguments, and finds your best responses — so you can focus on winning rounds.
Built by debaters, for debaters.
Features
Everything you need to prep, nothing you don’t.
Parse any backfile instantly
Upload your Verbatim docs. Backfile understands pockets, hats, blocks, tags, cites, and card bodies — no manual tagging required.
Search your entire file library
Every card, analytic, and block across all your files — searchable in milliseconds. Find that one impact turn from camp in seconds, not minutes.
AI-powered response advisor
Upload an opponent's case. Get ranked counter-evidence from your own files, plus AI-written analytics for gaps in your coverage.

Get your responses
Cards, blocks, and analytics from your own files, ranked by relevance and grouped by strategy. Export to Verbatim and you're ready.
