Катерина Козар · AI Content Creator · SMM
AI content and SMM. Author of the children’s YouTube channel Prostir Dumok — about 1 million views in 6 months, from zero. And the music AI project Space of Nostalgia.
AI Content Creator and SMM manager from Zaporizhzhia. I build visuals and content with artificial intelligence (AI): plan, copy, images, music, video. From management roles I kept the order — brief and audience first, then content.
I run two YouTube channels: the children’s Prostir Dumok and the music project Space of Nostalgia — Ukrainian covers and originals. Same production, different audiences. I work remotely.
Instagram and Facebook management, profile design, a monthly content plan, AI video for YouTube and Reels, thumbnails and banners.
Strategy, plan, copy, stories, profile visuals.
Platforms: Instagram, Facebook, YouTube, TikTok, Telegram.
Pictures and banners with AI, thumbnails, music.
Tools: Suno, Grok Imagine, Canva.
Idea, prompt, generation, edit, thumbnail, SEO title.
Tools: Kling, CapCut.
AI video in Ukrainian. Own channels: press play — the video starts here. Prostir Dumok began as songs for my own child, then became a test bed for the full AI cycle: prompt, video, music, thumbnail, SEO title.
285k views · 2:21 · channel #1
Why it’s here: strongest long video on the channel. Prompt, generation, edit, thumbnail, SEO title — one pair of hands. Organic, no budget, no team.
154k views · 1:10
Why it’s here: a short piece that still clears 100k. A series, not one hit — same production cycle.
115k views · 1:22
Why it’s here: another 100k+ title in the same cycle — prompt, generation, edit, SEO. Evidence of a system.
25k views · 465 likes · 4:25
Why it’s here: strongest original on the music channel. Adult audience, long-form hold. Same AI production, different tone from the kids’ YouTube.
2.2k views · 4:09 · original
Why it’s here: not only covers — new songs too. Smaller reach because it’s newer; with “Salty fate” it shows a series, not a one-off.
