Fluxcut is a web app that makes product demo videos with the help of AI agents. The user describes the product in a paragraph, and Fluxcut produces the script, footage plan, voiceover, music and thumbnail, stopping at each checkpoint for approval.
The company's pitch is that agents do the making while the user keeps the decisions. Approvals bind to the exact content the user saw, nothing is approved by default or by timer, and publishing never happens without the user saying so.
Fluxcut can be used directly in the app, or a user's own coding agent can run the process through a Fluxcut key. That second option is aimed at teams that already ship software with tools such as Claude Code.
The workflow has three phases. In the first, Fluxcut writes a brief naming the audience, the pain and the value, lists the shots it needs and drafts a script with one line per shot. The user approves, edits a line or sends it back with a note.
In the second phase, each line is voiced as its own take, music is composed to the exact length and three thumbnail concepts are drawn from the brief. Takes are checked for fit, loudness and clipping before the user hears them.
In the third phase the final cut is rendered the same way every time, with loudness levelled for the platform. The user downloads the MP4 with its thumbnail, title and description. If something changes later, Fluxcut shows what it must remake.
The most distinctive feature is dependency tracking. Fluxcut knows which parts of a video depend on which, so rewording one script line re-voices only that line. The music follows timing rather than words, so it stays, and the rest keeps its approval.
Quality checks run before the user sees anything. Voiceover takes are tested for fit, loudness, clipping and room under the music, and failures are retried up to three times. A note on one line, take or thumbnail steers only that retake.
Footage comes from the user: screen recordings and screenshots, which Fluxcut requests piece by piece with a reason. Videos export as 1080p MP4 in 16:9 or 9:16, and a user can pick the voice, delivery and pace, changing them for a single line.
Fluxcut is a web app that makes product demo videos from a one-paragraph description. It drafts the script, voiceover, music and thumbnail, and the user approves every step. Agents such as Claude Code can do the making if the user prefers.
Free is $0 for 2 videos a month. Pro is $39 a month for 10 videos, and Premium is $129 a month for 20 videos. Extra videos cost $5 each on Pro and $10 each on Premium.

Claude Code, Codex and Grok Build work with Fluxcut today. They connect through Fluxcut's MCP server with a key. The hosted agent on paid plans runs on Grok, from xAI.
Videos can be 16:9 landscape or 9:16 vertical and export as 1080p MP4. Length is up to 60 seconds on Free, 90 seconds on Pro and 3 minutes on Premium. Premium also offers videos up to 5 minutes at $15 each.
Not if your product has public pages the agent can film. For signed-in screens, you click Record once or let a local agent film them. You can also upload your own screen recordings and screenshots.
Yes. Fluxcut shows what it needs to remake and waits for your approval before republishing. Edits and partial remakes are free.
They are stored in your account and used only for your videos. Deleting a project removes its files permanently after 30 days, or sooner on request.
