FAQ

Suidasu is a cloud service that uses AI to extract data from images and PDFs. Simply photograph or upload documents like invoices, receipts, and business cards, and the system automatically reads and returns the data in a structured format.

When you register an account, a 14-day Trial plan (up to 100 free extractions) is automatically applied. Start by creating a data layout using a template (business card, invoice, etc.), then try uploading an image. See the Help page for detailed steps.

We support JPEG, PNG, GIF, WebP, HEIC/HEIF (iPhone photos), BMP, TIFF, and PDF. Maximum file size is 7MB for images and up to 10 pages for PDFs.

Yes, we support both iOS (iPhone/iPad) and Android. You can take photos and upload directly from the app. Face ID, Touch ID, and fingerprint authentication are also supported for secure access.

For standard printed documents (invoices, receipts, business cards, etc.), we achieve high extraction accuracy. However, accuracy varies depending on image quality (resolution, brightness, angle) and document condition. Each extraction result includes a confidence score so you can verify accuracy. Extractions with confidence below 70% are not billed, so you won't be charged for low-accuracy results.

Suidasu does support handwritten text recognition, but accuracy is currently lower compared to printed text. Neatly written characters and numbers within boxes tend to be recognized more reliably, while cursive or hastily written text may not be accurately recognized. We are continuously working to improve handwriting recognition accuracy. If the accuracy falls below the threshold (70% confidence), you will not be charged, so feel free to try it out.

Yes, extraction results can be manually corrected at any time. Open the target data from extraction history and directly edit the values of each field. You can correct only the specific fields where AI recognition was incomplete.

While standard OCR mode reads text, Image Recognition mode uses AI to analyze images without text (product photos, equipment condition, appearance photos, etc.) and extract information. For example, it can automatically determine product color, shape, condition, and other attributes.

PDFs are processed page by page, creating separate extraction results for each page. Up to 10 pages are supported, and each page's results are saved individually. Note that each PDF page counts as one extraction (e.g., a 5-page PDF consumes 5 extractions).

Yes, you can. Tabular data (item lists, attendance sheets, lists, etc.) can be extracted as multiple records from a single image. AI automatically recognizes rows and extracts each row's data individually. The confidence score is calculated as the average of all records.

A Data Layout defines which fields to extract from an image. For example, an 'Invoice' layout would define extraction fields like company name, date, amount, and line items. Create a layout and assign it to a project to enable business-specific extraction.

Recipe Generation is a feature that automatically suggests a layout (extraction fields) by uploading a sample image for AI analysis. It lets you create layouts for custom forms and documents without manually defining fields. Available on Trial and Standard plans and above.

Yes, we provide templates for commonly used documents such as business cards, invoices, receipts, and driver's licenses. Import them with one click to start using immediately — great for first-time users.

We offer 4 plans: Trial (14 days free, 100 extractions), Lite (¥0/mo + ¥88/extraction), Standard (¥3980/mo, 50 free + ¥50/extraction), Pro (¥14980/mo, 150 free + ¥30/extraction + API access). A paid plan subscription is required after Trial expires.

No, you are not. Extractions with a confidence score below 70% are excluded from billing. They also do not count against your free extraction quota. You will never be charged for results that don't meet the accuracy threshold.

After the Trial period (14 days) expires, you'll need to subscribe to a paid plan (Lite, Standard, or Pro). All data and layouts created during Trial are carried over, so you can continue using them seamlessly after switching plans.

Yes, you can change plans at any time. Upgrade, downgrade, or switch plans from the 'Plan & Billing' section in Settings. Changes take effect immediately.

Uploaded images and extracted data are encrypted and stored securely. All communications are encrypted via HTTPS, and data is automatically deleted after a certain period. Additionally, inappropriate images are automatically detected and blocked from upload.

Yes, with the operator feature, multiple people can upload images from the mobile app. There is no limit on the number of operators — unlimited on all plans. Administrators can manage all extraction results from the dashboard.

When you cancel your account, all associated data (extraction results, images, layouts, projects, etc.) will be permanently deleted. Deleted data cannot be recovered, so please export any necessary data beforehand.

Yes, available on the Pro plan. Generate an API key from the 'API Keys' page in Settings to access all 21 features via REST API or MCP (JSON-RPC 2.0). The same API key works for both methods. Everything you can do on the web — data extraction, layout management, exports — is also available through the API.

REST API is a general-purpose HTTP-standard API that can be called from any program, business system, iPaaS (Zapier, etc.), or AI agent (ChatGPT GPTs Custom Actions, etc.). MCP (Model Context Protocol) is a standard protocol optimized for integration with AI assistants (Claude Desktop, Claude Code, etc.). Both use the same API key and provide the same 21 features — choose the one that best suits your use case.

MCP (Model Context Protocol) is a standard protocol for AI assistants to integrate with external services. Since Suidasu supports MCP, AI agents like Claude can directly perform data extraction and layout management.

After subscribing to the Pro plan, generate an API key. You have two options: for REST API, call the endpoints from any HTTP client (curl, Postman, internal systems, iPaaS, etc.). For MCP, add Suidasu's endpoint and API key to your Claude Desktop or Claude Code settings file. See the 'API Integration' tab on the Help page for detailed setup instructions.
