Write the script. Hear the roster. Ship the video.

Qontent Tube is a Markdown-first voice and animation studio for Windows and Linux. It keeps your script, scenes, cast, narration, animation, and finished videos together in one calm workspace.

Start here

• Check runtime and provider requirements — see the supported systems, Deepgram key, render tools, optional AI services, and separate provider costs.
• Create your first voiceover — go from an empty workspace to a playable two-scene draft.
• Write a structured script — learn the small Markdown grammar Qontent Tube understands.
• Build a reusable cast — assign friendly voices and pacing to recurring speakers.
• Generate and review narration — create only the audio you need and revise without rebuilding.
• Work with local Markdown — bring your own editor and understand safe file reconciliation.
• Desktop help — learn how the packaged app starts, stores data, and shuts down.

New in 0.3: real captures

• Make a product demo — the complete workflow, and what it costs.
• Capture scenes — show real screenshots and recordings, framed and never redrawn.
• Validate and approve — see every problem, review privacy, and prove what a render used.
• AI adaptation — optionally turn a capture into an animation, with consent for every run.

New in 0.2: it's alive

• Studio and the animated stage — preview every scene as an animated video that follows the voice.
• Storyboards — edit scenes with forms, approve and lock them, and add AI backgrounds.
• AI drafting — draft scripts and storyboards from a topic, with your key or by copy and paste.
• Themes — bring your brand colors and fonts, with readability checks.
• Characters — build a cast that talks with the real voice.
• Languages — translate, re-voice, and keep every language in sync.
• Mobile formats — adapt scenes for Shorts, Reels, and TikTok.
• Rendering videos — export MP4, captions, chapters, and parts on your computer.

Qontent Tube is intentionally deterministic: it reads the structure you write instead of asking AI to guess where scenes and speakers begin. AI can draft for you, but every result is a reviewable draft, and your Markdown remains the canonical source.

Dogfooding -we needed, we created it ourselves

The 0.3 launch video was made with Qontent Tube 0.3, from real recordings of the app showing that video's own project.

The video below was made entirely with Qontent Tube 0.2. One Markdown script, one storyboard, two voices, a cast of two characters, three painted backgrounds, and three renders: this one, a Spanish version, and a vertical Short.

Our latest videos at La Rebelion Labs on YouTube have all been created using Qontent Tube.
