Coslynx: reels for your brand, made on your own computer. Three frames drawn by Content Factory: an orbit traced in hot ink, a turbofan engine taken apart in isometric, and an energy meter painted as an anime cel

Content Factory

Set up your brand or channel once. Content Factory finds what your audience wants to watch, researches it, writes the reel in the form your channel uses, voices it and animates every frame, on your own machine and your own Claude plan. A reel that does not clear the bar is never posted: it waits for you, with the reason.

Picks the topic
Live trends, Reddit, Hacker News, news and Wikipedia, read for your audience and voted on by a panel of strangers before a word is written.
Checks every fact
Each number and quote is matched to the source it came from before the voice is recorded.
Draws every frame
No image or video generators. Two film engines and 90+ looks, plus real, credited material from the open web.
Judged before it posts
Scored against hand-picked reels. Under 8 out of 10, it is fixed once, then held for you.

The Content Factory studio: a reel titled 'How does a lock know your key?' being filmed, 9 of 13 steps done, beside a held reel waiting for review with the judge's reason

The studio: the reel being made, what waits for you, and when the next one starts.

Every frame is made, not generated

A reel moves through several of these, each beat in its own look, joined by designed transitions.
