## What is Riff Engine?

Riff Engine helps creators pull useful, original ideas from their own experience. It is not a teleprompter. Each short card asks you to defend, diagnose, remember, advise, connect, or predict—then gets out of the way so you can speak naturally.

• Build an optional private experience profile, or skip setup
• Start with a bundled offline practice deck
• Run focused thought-extraction sessions with one prompt at a time
• Reveal a nudge only when you need it
• Choose Different Energy, More Like This, or Never Again to shape future sessions
• Create your own prompts and import compatible JSON decks
• Save session history and import an audio or video recording for on-device speech analysis
• Track publication outcomes and refine future card ranking

No account, subscription, or network connection is required. Cards, preferences, sessions, transcripts, analysis, outcomes, and calibration stay on your device by default. Optional advanced content sources are off until you configure them.
