When you build slides with AI, they often look polished but arrive as flat images, leaving you unable to fix even a single character. Kirigami.ai is a Japanese web service built to remove that roadblock. Drag and drop a slide image, PDF, or screenshot, and it produces a .pptx file in which text, shapes, and backgrounds sit as independent objects. It is developed by Taiyo Kimira, an individual developer based in Tokyo, Japan. The service sits exactly where a practical workflow needs it: draft with generative AI, finish in PowerPoint.
Key Features
- Editable .pptx from images and PDFs: Uploaded images and PDFs are analyzed and written out as slides you can open and edit directly in PowerPoint. Text becomes text boxes and shapes become shapes, so swapping wording or rearranging the layout works like ordinary slide editing
- Text restoration through OCR: Characters inside the image are recognized and rebuilt as text. The design specifically targets the broken or blurred characters that AI-generated slide images tend to contain, replacing them with clean text
- Layer decomposition: Backgrounds, shapes, and text are placed on separate layers, which makes partial edits such as “keep the background, fix only the heading” straightforward
- Batch PDF conversion: Multi-page PDFs can be processed in one pass, so an entire deck can be converted at once. Credits are counted per page
- Multilingual support: Text recognition covers 17 languages, so English decks work as well as Japanese ones
- More than a browser entry point: Alongside the web interface, an API is available, and the service can be called through Claude Code (MCP / Skills). That gives routine conversions a path to automation
Pricing
Pricing is credit-based: one image conversion consumes 10 credits, and PDFs consume 10 credits per page.
| Plan | Monthly price | Monthly credits | Approximate conversions | Main features |
|---|---|---|---|---|
| STARTER | $12 | 360 | 36 images | Text editing, batch PDF conversion, Web / API / Claude Code |
| PRO 20 | $20 | 600 | 60 images | The above plus priority support |
| PRO 40 | $40 | 1,200 | 120 images | Priority API access, top-tier support |
Payments are processed through Stripe, and you can cancel at any time from the dashboard. Japanese cardholders are billed in yen at their card issuer’s rate. The official pricing page does not state whether a free plan exists, so check the official site if you want to try the service first.

Pros & Cons
✅ Pros
- Turns image-only slides back into an editable state, so decks drafted with generative AI can be carried straight into real work
- Everything is done by drag and drop, with no specialist knowledge or setup required
- Multi-page PDFs can be processed in bulk, which also suits rebuilding existing documents
- With an API and Claude Code integration, it fits both one-off use and automated pipelines
- The credit system makes consumption easy to follow, and plans can be matched to the volume you need
⚠️ Cons
- No free plan is listed on the official pricing page, so starting out generally means paying
- Slides with complex design or heavy decoration may need manual cleanup after conversion
- OCR accuracy depends on the resolution of the source image and how degraded the characters are
- Monthly credits are capped, so converting large volumes of material requires a higher plan
- It is a service built by an individual developer, so anyone needing enterprise onboarding support or specific contract terms should confirm details in advance
Comparison with Similar Services
| Item | Kirigami.ai | Gamma | Irusiru | Adobe Acrobat |
|---|---|---|---|---|
| Main use | Convert images and PDFs into editable PPTX | Generate new slides with AI | Generate Japanese slides with AI | Convert PDF file formats |
| Input | Images, PDFs, screenshots | Text prompts, outlines | Text prompts | |

Gamma and Irusiru are tools for building slides from scratch, while Kirigami.ai returns existing image or PDF slides to an editable form. Their roles do not overlap, so the natural pattern is to pair it with a generation-side tool.
Who Is It For
- Anyone using AI tools that output slides as images, such as Nano Banana or NotebookLM, who is stuck at the final editing stage
- People who regularly have to rebuild supplied PDF documents in PowerPoint
- Business users who want to leave slide layout to other tools and only swap wording or figures themselves
- Developers who want to automate document conversion from an API or Claude Code
Summary
Kirigami.ai fills the gap left by generative AI: slides you can create but cannot edit. It does not generate decks itself, concentrating instead on the single job of returning images and PDFs to editable .pptx, which is where it pays off when combined with other slide-generating AI tools. Since it starts at $12 per month on a credit basis, the clearest way to judge it is to convert one document you already have and see whether the OCR accuracy and the amount of cleanup match your needs.
