No more lost ideas on the move
I’m always on the move, and I used to lose best ideas because I hated taking notes while watching videos. Castifai helps me to capture inspiration from videos effortlessly, without ever having to go back and hunt for the right sentences. Such a life hack!
Castifai helps me share my favourite content
I find Castifai useful for writing posts about my favourite content, as it does most of the writing and graphics for me. I care about giving credit to original writers, so I appreciate that it allows me to link the source video easily and mention the creator. Castifai is my goto tool for my LinkedIn posts.
Castifai is my new way of sharing what I learn
Castifai takes the way we naturally learn - watching videos, podcasts, talks - and turns it into real, shareable content. It's AI that actually fits into your style.

Finally posting consistently
It used to take me an half an hour to turn a podcast I liked each LinkedIn post. Now I watch it during my commute, paste the link when I get to the office, and have a draft ready in minutes. I've posted more in the last month than the entire previous year.

It actually sounds like me
I was skeptical about AI writing tools - everything always sounded generic. But Castifai learned my tone after just a few examples. My colleagues can't tell which posts I wrote from scratch and which started from a video on Castifai.

Content for my whole region in one click
I manage business development across the Nordics. I find great English content but my LinkedIn audience is mixed - Swedish, Norwegian, Danish. With Castifai I create the post once and publish in three languages. Same insight, local feel, no translator needed.
