Make the launch video
in your head.
StartupVidz is the AI video tool for founders — built around a hand-coded intelligence engine that plans your video shot by shot. Edit scenes, lock the parts you love, regenerate the rest.
No API keys required · runs fully offline · sub-100ms blueprints
Most AI video tools are slot machines.
StartupVidz is a director.
Plan, lock, regenerate. Every step keeps your taste in the loop.
State your intent
Plain English brief. Quantum extracts product, audience, format, tone, runtime, and CTA in milliseconds.
Get a real blueprint
Not a script. A structured scene plan: hook, beats, value prop, CTA. With director's notes, framing, motion.
Direct, lock, ship
Lock the scenes you love. Rewrite the rest in plain English. Compare versions. Export when it lands.
Edit by intent. Lock by taste.
Tell Quantum what to change in plain English. Every revision creates a new branch in the version graph — locked scenes are guaranteed untouched.
- Scene 01 — locked, never touched.
- Scenes 02–06 — eligible for rewrite.
- New version branched from v2.
Meet Quantum.
A director, not a wrapper.
Most AI video tools are thin layers over a generic LLM. Quantum is different. It's a hand-built composition engine: an intent parser, a curated startup-video lexicon, a library of proven narrative arcs, and a rewriter that respects locks.
Every blueprint is composed locally in milliseconds. No tokens. No quotas. No gambling. Just a director that's already shipped a thousand startup videos — encoded once, instantly available to you.
Pulls product, audience, format, tone, runtime, CTA from a free-text brief.
Picks one of nine narrative arcs — proven shapes for each video format.
Distributes runtime across beats, respecting min/max durations per beat.
Hand-curated voiceover, captions, and visual notes — tone- and style-aware.
Per-scene shot framing and motion notes from a domain rule set.
Filters jargon, repetition, and bad pacing before output.
Nine formats. Each one a proven shape,
not a generic template.
Quantum picks the narrative arc that fits your format and runtime — then composes the scenes.

No LLM in the loop
Quantum is a hand-built composition engine. Your script is generated locally, in milliseconds. Your data never leaves the machine.

Lock any scene and revise the rest. Never lose the line you loved while reworking the hook.
Version branching
Each revision is a new branch in the version graph — never a destructive overwrite.
Edit by intent
'Make scene 1 punchier.' 'Shorten by 5 seconds.' 'Cut the jargon.' Quantum understands the axes that matter.

No spinners, no quotas, no token bills. Run as many drafts as you want — Quantum is yours.
Render providers, swappable
Quantum tells the video model what to make. Plug in Runway, Veo, ElevenLabs — or whatever's best next year.
Direct your AI video.
Scene by scene.
Plan, edit, and ship the launch video your startup actually deserves — without the agency, without the slot machine.
