Mavericks Inc. to Update Video Generation AI "NoLang" Slide Generation Function Soon! Supporting SNS 4:5 Feed Slides Rich in Diagrams and Design!

Mavericks Inc., a Japan-based company providing the video generation AI "NoLang," (Headquarters: Bunkyo-ku, Tokyo; Representative: Shota Okuno, President and CEO) is scheduled to launch a new feature for NoLang's slide generation function. This update will enable the generation of 4:5 size (1080×1350px) feed-compatible slides that are rich in diagrams and infographics (scheduled for release at the end of April 2026).

Traditionally, NoLang's slide generation function primarily offered simple, information-focused slide designs. However, with this update, AI will automatically generate highly designed, professional-grade feed-posting slides that include diagrams such as comparison tables, checklists, rankings, timelines, and scorecards, as well as infographics and rich decorations. This will create an environment where users without specialized design knowledge can quickly create slides for a wide range of SNS feed applications, including Instagram carousels, Facebook feeds, LinkedIn document posts, and X (formerly Twitter) image posts.

The Mainstreaming of Instagram Feed and Carousel Posts, and the Production Man-Hour Challenges Faced by Companies

Instagram has grown into a major SNS alongside LINE and YouTube, with over 66 million monthly active accounts in Japan (*1). On Instagram, the recommended aspect ratio for feed posts is 4:5 (1080×1350px), which minimizes top and bottom margins and occupies almost the entire vertical screen of a smartphone, making it a central format for corporate information dissemination (*2).

Among these, "carousel posts," which allow multiple slides to be displayed consecutively, are attracting attention as the format most likely to gain engagement on Instagram. According to the latest benchmark analysis by Socialinsider, which analyzed 35 million Instagram posts across 447,613 pages, carousel posts had an average engagement rate of 0.55%, surpassing Reels (0.52%) and single images (0.37%), making them the highest-engaging format as of 2025 (*3). The structure that allows users to "swipe through" to convey storytelling, comparisons, and procedures that cannot be fully expressed in a single static image is highly valued by algorithms, and the main battleground for information dissemination and brand awareness expansion using feeds is clearly shifting to carousel posts.

On the other hand, companies face serious challenges in continuously publishing carousels on Instagram feeds. A "Survey on the Reality and Challenges of Creative Production in Instagram Operations" conducted by eclore Inc. in January 2025, targeting 150 Instagram operators, found that "time and effort required for shooting and editing" was the most common challenge at 44.7%, followed by "lack of specialized design and video editing skills" and "running out of ideas and creative direction to attract attention," both at 42.0% (*4). This indicates that in addition to the practical hurdles in the production現場, the burden of continuously generating new ideas is a significant barrier for those in charge.

Furthermore, a survey targeting 2,134 corporate SNS managers revealed that approximately half cited "lack of internal resources" as their biggest challenge (*5). Even knowing which formats yield high engagement, the inability to continuously produce them, coupled with the high production costs and operational man-hours, presents a significant hurdle for many companies.
