Kortex · content engine

Your content engine. Built around your business. 

Kortex writes, voices, captions, cuts and publishes short video — every day, on five platforms, without an editor being opened. We built it to run Kaplex Academy. Everything below is that engine, working. We’ll build you one.

Volume and cadence only. We don’t publish view counts here — the pipeline is what’s for sale, and an audience is something you earn.

The line

Eight stages. Two of them are you.

Everything between the brain-dump and the post runs on its own. The two places a human stays in the loop are there on purpose — picking the script is where taste beats automation, and watching the result once is what stops a bad render going out.

01
Brain-dump
Talk at it. A topic, a rant, a rough idea, or a clip you recorded on your phone.
You
02
Script
Three scripts come back written in your house style. You pick one.
Claude
03
Voice
Spoken in a consistent voice — or your own recording, kept as-is.
ElevenLabs
04
Captions
Transcribed to word-level timings, so captions land on the word, not near it.
Whisper
05
B-roll
Cutaways chosen by what the line means. Nothing matches, nothing is inserted.

The week

Five videos, two ways.

Nothing here is a time saving we invented. The left column is what the work actually is when a person does it; the right is which of those steps stop being yours.

By hand
You are the studio.
  • write Five scripts, from a blank page, in your own voice.
  • record Five takes. Then the retakes.
  • caption Type them, then nudge every line until it lands.
  • cut Find b-roll. Trim it. Place it. Watch it back.
  • brand Logo, outro, music, levels — every time.
  • post Five uploads, five sets of titles and tags, five times.
Through Kortex
You are the editor-in-chief.
  • talk Brain-dump the idea. However it comes out.
  • pick Choose one of three scripts. Fifteen seconds.
  • Voice, captions, b-roll, brand, render.
  • watch See the finished video once.
  • Titles and tags written per platform.
  • Posted on the calendar you set.
Word-level timing

Captions that land on the word.

Every word gets its own timestamp, so captions hit in time with the voice instead of near it. The music bed ducks underneath automatically. This is running live below — it is the same mechanism the renderer uses.

Most people think the hard part is making the video. It is not. It is doing it again tomorrow.

Output

Built for the feed, not for a timeline.

This is the shape it ships in.

Three real shorts, straight off the line — script, voice, captions, cutaways, brand and outro, none of it touched in an editor. Nine-by-sixteen, captions inside the safe zone so nothing is swallowed by a platform’s own interface, music ducked under the voice.

B-roll picked by meaning.

A model reads the line and pulls the cutaway that fits what is being said — not whatever shares a keyword with it. The interesting part is what happens when nothing fits.

3 cutaways surfaced from the library for that idea.

Distribution

One finished video. Every destination.

Titles, captions and tags are written per platform, then posted through those platforms’ own APIs on the schedule you set. There is no export-and-upload-it-yourself step left in the system.

What it does, and what it doesn’t.

Most tools in this category are demos. This one runs in production every day, which also means its edges are known. Here they are.

Short vertical video, end to end

Script, voice, captions, b-roll, brand, render, schedule, post.

does
Publishes by itself

YouTube, Instagram, Facebook, Threads and Discord, through their own APIs.

does
Varies on purpose

Variation engines tuned to your subject matter, so forty videos do not look like one video forty times.

does
Long-form

Shorts only. There is machinery for harvesting clips from a long recording, but no finished long-form video exists yet.

does not
Log in and self-serve

It runs one brand today. Onboarding another means platform approvals measured in weeks of calendar time, so it is run for you rather than sold as a seat.

does not
Promise an audience

It guarantees output, not results. Anyone who tells you otherwise about content is selling something.

does not
Questions

The things people ask.

Talk at it, pick one of three scripts, and watch the finished video once before it goes out. That is the loop. Everything between those steps — writing, voicing, timing, cutting, captioning, branding, scheduling, posting — runs without you.

It posts. There is no export-and-upload-it-yourself path left in the system. Finished videos go to YouTube, Instagram, Facebook, Threads and Discord through those platforms’ own APIs, on a schedule you set.

Because that is the one decision where taste beats automation, and it costs you about fifteen seconds. Three options come back written in your voice; you choose. Automating that away would make the output blander, not faster.

By meaning, not keyword matching. A language model reads the line and picks a cutaway from a 579-clip library that fits what is being said. When nothing genuinely fits, it inserts nothing — an empty beat beats a stock shot that has nothing to do with the sentence.

Not yet, and it would be easy to pretend otherwise. Kortex runs one brand right now, and onboarding a new one means platform approvals that are a multi-week process with YouTube and Meta — calendar time, not engineering time. It is offered as a done-for-you engagement, not as software you log into.

No. Short vertical video only. There is machinery for pulling clips out of a long recording, but no long-form video has been finished or published, so it is not something to buy today.

How it works

Built around your business. Not a template.

This is not a subscription you sign up for and point at your channel. It is a content engine assembled from the ground up around what you actually do — your voice, your house style, your b-roll, your platforms, your posting rhythm.

The part most people miss is variation. A channel that posts the same shape of video forty times reads as a bot, and the platforms treat it that way. Kortex is set up with variation engines tuned to your subject matter, so the output stays recognisably yours without becoming repetitive.

01
We learn the voice

House style, phrasing, the things you would never say.

02
We build the library

B-roll, music, logo, outro and caption styling that look like you.

03
We tune the variation

Domains, angles and formats set so no two weeks feel the same.

04
We connect the platforms

Publishing runs on your accounts, on your schedule.

Also from Kaplex

Kortex is one machine of several.

Kaplex Industries builds the software local businesses actually run on — quoting, operations, lead generation, content and AI visibility. Same idea applied to a different bottleneck each time: take the part of the work that is repetitive and exact, and let software do that part.
