The flow editor
Templates for every format — PF, LD, Policy, Congress — preload speech order, timer presets, and column structure. Just type. Keyboard-first navigation keeps your hands where they should be.

AI · response engine
Highlight any opponent argument and FlowMaster drafts the response, the cross-ex question, or the warrant you're missing — phrased the way debaters actually talk.
"Their adaptation framing concedes the magnitude — pivot to scope, not severity."

How the AI knows
Every suggestion is search-grounded against current sources — no hallucinated citations, ever. The model itself is fine-tuned on real cases and blocks from NSDA champions, TOC finalists, and working-circuit debaters, so it talks like a real partner — not a chatbot.
Your tournament, in one place
Past flows, prep saved, hours practiced, and a one-click start to your next round. Picks up exactly where the last round ended.
Our credo
Every shortcut, every default, every AI prompt was tested in real rounds — not a marketing meeting. The team behind FlowMaster has sat behind the same flow pad you have, at 7 a.m. on a tournament Saturday, on three hours of sleep and bad coffee. That perspective is in every pixel.
Intelligence
Specialized tools for the moves you make every round — fact-checking a claim, generating cross-ex, reading a round post-hoc — backed by a full chat for when you need to think out loud.

Why FlowMaster
01
Every shortcut, every default, every template was made by people who've actually had to flow a 1AC in three minutes.
02
Tournament Wi-Fi is a rumor. Flows save locally, then sync the moment a signal returns. Nothing is ever lost between speeches.
03
No paywall, no trial timer. FlowMaster is free for the entire debate community, today and for as long as we can keep it that way.
Questions
Public Forum is fully supported. Lincoln–Douglas, Policy, and Congress are in beta — the editor, timer, and collaboration all work, but format-specific templates and AI prompts are still being tuned. Custom templates are on the roadmap.
Yes. Every flow is written to disk before it touches the server. When you reconnect, edits sync automatically; conflicts resolve to whichever flow was most recently modified.
Nothing. FlowMaster is free on the Mac App Store. No trial, no premium tier — at least, not today.
The intended use is a partnership or small team — two to four active editors per flow. The room scales further; the UX is tuned for that scale.
macOS 14.6 (Sonoma) or later, on Apple Silicon or Intel. The app is universal binary; install size is under 50 MB.
