The last mile of video, automated

The cut is done.
Now it ships itself.

Finalizer takes your locked master and builds the whole delivery pack — captions, platform versions, metadata, scheduling — then waits for one thing: your approval.

You finished the edit.
Why are you still working?

Captions, crops, exports, titles, uploads — the last mile eats a fifth of every project and none of it is craft. Finalizer turns it into a pack that builds itself.

You press publish. AI drafts, automation moves files — nothing goes live without your approval. Ever.
STEP 01

Drop the locked master.

One file in. Finalizer reads duration, aspect ratio, and loudness, re-transcribes the final cut — so captions match the edit exactly, not the rushes.

STEP 02

The pack builds itself.

Styled captions, platform versions with safe-area crops and normalized audio, drafted titles, chapters, and descriptions. Everything named, organized, and consistent — the way a good assistant would leave it.

STEP 03

Approve. It ships on schedule.

Review the pack, set the calendar, press approve. Finalizer publishes each version to the right platform at the right time — and a human decision sits in front of every send.

AI drafts.
You decide.

The failure mode of automated publishing isn't bad AI output — it's auto-publishing bad AI output. Finalizer is built around the approval gate, not around removing you.

Cloud AI. Your own key.

Metadata and caption drafting with frontier models via your own API key. Pay per use, cents per pack — no subscription stack.

Local AI. Fully on-device.

Switch to local models and the whole pipeline runs on your Mac. Confidential client work stays exactly where it is.

One master in.
Every deliverable out.

Platform versions

9:16, 1:1, 16:9 with safe-area crops and per-platform loudness normalization from one master.

The approval gate

Nothing goes live on its own. Review, adjust, approve — the human stays in front of every publish.
