Terminal Demo Video Maker

Show a CLI the way it deserves: typed-command animations in a clean terminal component, with monospace type sized for phones — not a desktop screen capture squinted at on a 6-inch screen.

How it works

From CLI to demo video

Write what the terminal shows — the studio animates it.

1
ScriptDescribe the tool and the demo you want to give. The AI drafts a Short-length walkthrough grounded in your docs; you edit it line by line.
2
ScenesEach step becomes a terminal scene: the command types itself out, the output appears. You write both, so there are no typos, no waiting on slow commands, no secrets leaking into frame.
3
NarrationAI narration from 24+ voices, duration-synced to each scene — or record your own walkthrough with the built-in recorder.
4
PublishRender a native 9:16 Short and publish to YouTube in one click, with AI title, description, and auto thumbnail.
Included

What you get

The demo you meant to give, every time.

Typed commands, not screen captures

The terminal is a motion component. You decide the command and the output — deterministic, clean, and free of the flaky-network retake.

Monospace that survives 9:16

A desktop-width terminal recording turns to mush on a phone. The component is sized for vertical video, so flags and paths stay readable.

Change a flag without re-recording

Renamed a subcommand? Edit the scene text and re-render. The demo never goes stale because it was never a recording.

Mix terminals with other scenes

A code card for the config file, a chart for the benchmark output, a diagram for what just happened — 100+ components in one layered editor.

Word-level trim on your voice

If you narrate it yourself, local Whisper transcription with word timestamps lets you cut filler words and silences from the transcript.

Free pilot, your keys

No credit card, no watermarks. AI usage runs on your own provider keys with zero markup.

FAQ

Common questions

Does it run my commands for real?

No — you author what the terminal shows. That is the point: no typos on camera, no waiting for installs, and nothing sensitive from your real shell ends up in the video.

Can I paste output from a real session?

Yes. Paste the real output into the scene and trim it to the lines that matter — long scrollback is the enemy of a 60-second Short.

My CLI changed — do I remake the demo?

Edit the command or output text in the scene and re-render. Scenes are editable objects, not baked footage.

Can I still show my actual screen?

Yes — a built-in screen and camera recorder is available when you want a live take, with word-level trim and filler-word cleanup afterwards.

What does it cost?

ReelMint is free during the founding-creator pilot. Generation runs on your own API keys, billed by the provider with zero markup.

Give the demo without the retakes

Author the terminal, narrate it, publish it — free during the pilot.
