Mavericks Inc., a Japanese company that provides the video generation AI "NoLang," headquartered in Bunkyo-ku, Tokyo, with Representative Director and President Shota Okuno, announced that it plans to update NoLang's slide generation feature to support 4:5 size (1080x1350px) slides optimized for Instagram feed and carousel posts (scheduled for release at the end of April 2026).
This update will enable the automatic generation of 4:5 slides suitable for Instagram feeds from text or PDF documents. After generation, users can flexibly refine the slides using three editing modes: text editing, AI editing, and page insertion. This creates an environment where even users without design knowledge can mass-produce various SNS feed content, such as Instagram carousel posts, Facebook feeds, LinkedIn, and X.
■ Popularization 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 in Japan, with over 66 million monthly active accounts (※1). On Instagram, the recommended aspect ratio for feed posts is 4:5, making it a central format for corporate information dissemination (※2).
Among these, "carousel posts," which allow multiple slides to be displayed continuously, are attracting attention as the format most likely to achieve engagement on Instagram. According to the latest benchmark from 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%). This indicates that carousel posts were the highest-engaging format as of 2025 (※3). The structure that allows users to "swipe through" to read a story, comparison, or procedure that cannot be fully conveyed in a single still image is highly rated by algorithms. The main battlefield for information dissemination and brand awareness expansion using feeds is clearly shifting towards 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 eye-catching ideas and production concepts," both at 42.0% (※4). This suggests that in addition to the practical hurdles in the production field, the burden of continuously generating new ideas is a significant obstacle for those in charge.

To solve the content creation challenges in corporate SNS feed operations, the video generation AI "NoLang"'s slide generation feature is scheduled to support 4:5 size slide generation optimized for Instagram feed and carousel posts (scheduled for release at the end of April 2026).
Based on input text or PDF documents, the AI will automatically generate 4:5 vertical slides that almost fill the screen in the Instagram feed. Users can provide design instructions such as "bright and pop design that attracts attention in the feed" or "calm and trustworthy design for B2B," as well as content/composition instructions like "carousel structure that assumes swiping, presenting the conclusion on the first slide and explaining the reasons in subsequent slides."
It is possible to create feed-compatible slides by specifying the layout.
