Katalist

Katalist is a Slovenian-founded generative-AI startup building an end-to-end pre-production workspace for video: writers and directors can import or draft a script, let the system break it down into beats, shots, and storyboards, generate consistent character and location renders, and iterate on the look of every scene before a single frame is filmed. The key differentiator is character- and setting-consistency across shots — the hard problem that plagues early image and video models — which Katalist addresses with reference-conditioning and scene graphs rather than naive prompt chaining. The target users are in-house content teams at brands, boutique production studios, and advertising agencies that have to produce far more video than their traditional pipelines can absorb, and that need a visual ideation layer that survives client feedback cycles. The company graduated from 500 Global's Eurasia program and is one of the more interesting European pre-production tools competing with the LTX Studio / Showrunner generation of US AI-film products.
