About this tool

Purpose

Jimakuai provides enterprise teams with a "single input, multi-format output" conversion service for video content. A typical input is a long video, such as a webinar, training video, or recorded talk; outputs include English-Japanese bilingual subtitles, vertical subtitled Reels/short video clips, and brand-designed carousel posts, along with cover images and post copy. It is officially positioned as content transformation for enterprise teams, with the core selling point being that no reshoots and no in-house editing team are required.

Main Capabilities

  • English⇄Japanese subtitle translation: For technical videos of 60 minutes or more, such as DX training, e-learning, webinars, and recorded meetings, offering terminology management and 24-hour delivery.
  • Terminology management and human QA: The official description states that subtitle translation includes a terminology database and human QA; after the pipeline produces output, bilingual reviewers polish each deliverable.
  • Short video and carousel repurposing: Recorded webinars or talks can be converted into vertical Reels, subtitled clips, and brand-designed carousel posts, including cover images and post copy. Each long video can produce 8 Reels and 4 carousels, and the official claim is that one video can support weeks of publishing.
  • Delivery formats: Subtitles are delivered as SRT, VTT, or burned-in subtitles; Reels, carousels, covers, and post copy are delivered within 5 business days.

How to Use

  • The official process is described in three steps:
  1. Send the video: Just provide a link; Google Drive, Dropbox, or an unlisted video URL is supported; recorded webinars, training courses, and talks can be used directly.
  2. Pipeline conversion: Transcription, translation, editing, subtitling, and design are completed in the same process, and then bilingual reviewers polish each asset.
  3. Publish: Subtitles are delivered within 24 hours, and Reels, carousels, covers, and post copy are delivered within 5 business days; the official claim is that same-week publishing is possible.

Use Cases

  • Enterprises that need to add English-Japanese subtitles to long technical videos (DX training, e-learning) and share them with overseas teams.
  • Content and marketing teams that want to repurpose recorded webinars, training, or talks into vertical short videos and social media carousels.
  • Teams with ongoing publishing needs that require volume-based subscriptions or fully managed content operations.

The official enterprise case provided is Toyo Engineering: used for English-Japanese subtitle translation of DX training and technical videos, sharing content of 60 minutes or more with overseas teams within 24 hours. It also officially operates two media brands to validate the same pipeline: AIブリーフ (daily Japanese AI news carousels and short videos) and VibeCoders (turning event recordings into Reels and carousels).
