I still remember the first time a webtoon "moved" on my screen. I was on the 1호선 into Seoul, scrolling a panel like always, and the character's hair just... swayed. A tiny piano sting came in. I stopped scrolling and stared at my phone for a second. That was maybe two years ago, and what's happened since in webtoon tech has moved faster than almost anything else I track in Korean IT.
This isn't a "what is a webtoon" post. What I want to walk through is the weirder part: how AI production tools, motion rendering, voice synthesis, and chat-based interactive fiction are quietly turning a static comic into something that doesn't have a name yet. Not quite animation. Not quite a comic. Not quite a game.

Why Static Comics Stopped Being Enough
Here's the blunt business reason. Korea's domestic webtoon market crossed ₩2 trillion in 2023, up roughly 19.7% year over year, and 2026 global projections put the industry between $10 and $14 billion, growing at a CAGR north of 30%. That growth doesn't come from more people reading vertical scroll the old way — it comes from platforms fighting YouTube Shorts, TikTok, and Reels, all of which train users to expect motion and sound by default.
So Naver and Kakao made a bet: instead of competing against short-form video, absorb it.
The Video Episode Format — Comics That Act Like Shows
The clearest example is Naver Webtoon's "Video Episode" format, trialed on the English-language service in mid-2025 and expanded through 2026. It takes an existing vertical-scroll series and layers in image motion, sound effects, music, and voice acting, running around five minutes per episode. Not a full anime adaptation — the art is still original panel art — but it moves and talks.
What's clever isn't the tech itself, it's the reuse. Studios re-rig existing IP instead of building a new animation budget from scratch. Compared to a traditional anime adaptation, which can take a year or more with a full production studio, a video episode can go out far faster since the source art already exists.
Cuts and Cuts Make — Turning Readers Into Editors
Then there's Cuts, Naver Webtoon's short-form animation platform, and its companion app Cuts Make. This one genuinely surprised me. Instead of studios doing all the motion work, Cuts Make hands editing tools to fans — letting them pull characters and panels from creator-approved IP into their own one- to two-minute clips. Two features stand out: "Character Meme," dropping characters into meme templates, and "Webtoon MV," turning panels into music-video style edits.
It's a UGC play, plain and simple — fan clips pull new readers back to the original series. Basically the webtoon version of what fan edits already do for K-pop and K-drama, except now officially sanctioned and tooled.
byUs — When You Can Chat Your Way Into the Story
The part that feels like a genuine new format, not just a new wrapper, is byUs — Naver Webtoon's AI story-chat service that launched fully in July 2026. Readers talk directly with characters from creator-approved series and steer new narrative branches, choosing "original story" mode, extending the established world, or "fan story" mode, setting new situations for characters you already know.
This directly answers the copyright and explicit-content controversy dogging unofficial AI character chat apps in Korea. By limiting everything to creator-approved IP, Naver Webtoon is trying to turn participatory fan fiction into a legitimate product rather than a legal gray zone. Whether that model holds up is still an open question, but it's a genuinely different structure than a comic, a game, or a chatbot alone.
How Kakao's Helix Shorts Is Racing Naver
Kakao Entertainment isn't sitting still. Their answer is Helix Shorts, an AI-driven short-video tool that automatically analyzes a webtoon's panels and dialogue and generates a short video — automating what Naver's Cuts team does by hand or through fan tools. Unlike Naver's more manual, fan-facing Cuts Make, Helix Shorts leans into full automation on the studio side, which scales faster across a huge back catalog but can feel less personal in output.
What This Means for the Business Side
None of this happens for art's sake. Naver Webtoon's international revenue alone passed ₩500 billion in 2023, and ad and subscription revenue keep climbing as near-nationwide 5G coverage has stretched average session lengths noticeably longer than a couple years back. Longer sessions mean more room for ads and upsell moments for premium formats like Video Episodes. There's a defensive angle too: illegal webtoon distribution is estimated at several hundred billion won a year, and richer formats like voice-acted episodes and interactive chats are tougher for piracy sites to simply screenshot and republish.
Insider's Insight: What I Think Actually Sticks
Okay, personal opinion time. I've spent enough years around Korean tech rollouts — from fabless AI chips to EV platforms — to have a jaded radar for "features that get a press release and quietly die in six months." My honest read: Video Episodes and Cuts stick around because they solve a real behavioral problem, shorter attention spans meeting an existing content library. byUs is the one I'm unsure about. AI companion chat is a crowded, messy space in Korea, and creator-approved IP is a smart legal shield, but that alone doesn't guarantee emotional stickiness. I've watched "safe, sanctioned" versions of viral trends underperform messier unofficial competitors before. I'd love to be wrong here.
FAQ
What is a webtoon video episode? A webtoon adapted with image motion, sound effects, music, and voice acting, running around five minutes, first trialed on Naver Webtoon's English service in 2025.
Is Cuts the same as a video episode? No. Cuts and Cuts Make are short-form fan or auto-generated clips of one to two minutes, while video episodes are fuller adaptations of a full chapter.
What is byUs and when did it launch? Naver Webtoon's AI story-chat service, launched fully in July 2026, letting users converse with creator-approved characters and build new story branches.
How big is the Korean webtoon market in 2026? South Korea's domestic market passed ₩2 trillion in 2023 with about 19.7% year-over-year growth; the global market is projected at $10–14 billion for 2026, growing above 30% CAGR.
What is Kakao's Helix Shorts? An AI tool that automatically analyzes webtoon panels and dialogue to generate short-form video, competing directly with Naver's Cuts ecosystem.
Why are platforms investing so heavily in these formats? Partly growth, partly defense — richer formats extend session times for ad and subscription revenue, and they're harder for piracy sites to rip than plain static images.
