Fluxcut

Fluxcut is a web app for making software and website promo, demo, and how-to videos using AI agents and manual controls.

Fluxcut is a web app for making promos, demos and how-to videos for software and websites. You describe the product and Fluxcut, or a connected AI agent, writes the script, gathers screen footage, records the voiceover, composes music, paints a thumbnail and renders the finished video. You review and approve each step before publishing. You can run agents on your computer or on Fluxcut, using models like Claude Code, Codex or Grok CLI. The app breaks the process into six distinct steps from the brief to the final render. If you edit any part of the project, Fluxcut recalculates only the pieces your edit touches while keeping your other approvals intact.
