About "イルシル"
What is Irusiru
Irusiru is a tool that auto-generates Japanese business-document slides with AI just from text you enter. Provided by Irusiru Inc., it bills itself as "an AI-powered service specialized for Japanese business scenes that automates slide and document creation." With 3,000+ Japanese templates, even non-designers can make pro-quality slides quickly. According to the company, it cuts document-creation time by about 70% and is used by 300,000+ people cumulatively.
To use it, enter keywords or long text and the AI proposes a slide structure and content, laying it out along a template automatically. After generation, you can edit text and design, and use parts like icons and charts. Being optimized for Japanese documents is what most distinguishes it from overseas slide generators.

Reuse your slides as PowerPoint assets
Beyond generation, Irusiru supports PDF and PowerPoint (PPTX) export, with improved export fidelity. For businesses there is also a PowerPoint plugin (released June 2026) that turns your company's slide assets into a library, reusable with one click from inside PowerPoint. Document creation that tends to be siloed can be run as an organizational asset.
With the PowerPoint plugin, you can pick design themes and reuse existing slides from inside the PowerPoint you already know. You can quickly rebuild sales materials and the like while keeping your brand.

How it differs from other AI slide generators
