Frequently Asked Questions

Gemina is an AI-powered document processing platform that extracts structured data from any document. Upload invoices, contracts, forms, or any document type and receive accurate, structured JSON data within seconds — via API or web console.

Gemina processes invoices, receipts, contracts, purchase orders, delivery notes, credit notes, forms, applications, bills of lading, customs forms, and virtually any document type. For invoices, Gemina extracts header fields and line items out of the box. For other document types, you can create custom templates to define exactly what data to extract.

Gemina uses an agentic AI architecture where multiple specialized AI agents work together. Documents flow through a graph-based pipeline: OCR extracts the text, AI models analyze the content and structure, and validation agents cross-verify the results. This multi-agent consensus approach delivers higher accuracy than single-model systems.

Gemina supports over 100 languages with automatic language detection, including Latin, Cyrillic, Arabic, Hebrew, and CJK (Chinese, Japanese, Korean) scripts. Right-to-left languages and mixed-language documents are handled seamlessly.

Gemina achieves 90–100% accuracy on document extraction, depending on document complexity and model selection. The multi-agent architecture cross-verifies results across multiple AI models, significantly reducing errors compared to single-model approaches. You can further boost accuracy by enabling Thinking and Evaluation modes.

Sign up for a free trial — no credit card required. You'll receive 500 credits to process documents using all AI models and features. Generate an API key from the console, and start extracting data within minutes.

The free trial includes 500 processing credits with full access to all features: all three AI models (Invictus, Praetorian, Velox), all extraction types, custom templates, data residency options, and enhanced privacy controls. It's the same feature set as the Gold plan.

No. The free trial requires no credit card. You can explore the full platform and process documents with your 500 credits before deciding on a plan.

Once your trial credits are exhausted, you'll be prompted to choose a paid plan. Select any plan (Bronze, Silver, or Gold) and your new credits will be available immediately after payment.

Each document processing operation costs a specific number of credits based on the extraction type, AI model, and optional features you enable. For example, extracting invoice headers costs fewer credits with Velox (speed-optimized) than with Invictus (maximum accuracy). Visit the Pricing page for the full credit cost table.

Gemina offers three subscription tiers — Bronze, Silver, and Gold — each with increasing credit allocations, template limits, data retention periods, and support levels. Enterprise plans with custom pricing and volume discounts are also available. Visit the Pricing page for current details.

You can purchase top-up credit packs at any time from the console without changing your plan. Top-up credits are available immediately after purchase.

No, monthly credits expire at the end of each billing cycle. Choose a plan that matches your expected usage, and purchase top-up packs for occasional spikes.

Yes. Top-up credit packs are available for purchase at any time from the Subscription page in the console. Credits are added to your balance immediately.

Yes, you can upgrade or downgrade your plan at any time from the console.

Enterprise plans offer pay-as-you-go pricing charged in dollars rather than credits, with volume discounts, unlimited templates, a dedicated account manager, SLA guarantees, and custom data residency options. Contact our sales team for a custom quote.

Payments are processed through Paddle, which supports credit cards, debit cards, PayPal, and various local payment methods depending on your region.

Gemina supports PDF, PNG, JPG, JPEG, GIF, and WEBP files. File size must be between 1 KB and 10 MB.

Most documents are processed in 4–6 seconds. Enabling optional features like Thinking mode (enhanced reasoning) or Evaluation mode (quality validation) may add processing time but improves accuracy for complex documents.

Yes. Page limits vary by extraction type: up to 30 pages for custom templates, 15 pages for OCR, and 10 pages for invoice extraction. Credits are charged per page.

Invoice header extraction includes vendor and buyer details (name, address, tax ID, email, phone), invoice number, dates, currency, subtotals, totals, tax breakdowns (supporting 20+ international tax types including VAT, GST, HST, and more), payment method, and document type classification. Line item extraction captures descriptions, quantities, unit prices, totals, and per-line tax amounts.

Yes. Gemina supports handwriting recognition (ICR) for both cursive and printed handwriting, including signatures and annotations.

If processing fails, credits for that extraction are automatically refunded to your account. You'll receive a detailed error response indicating what went wrong, and you can retry the extraction.

Yes. Gemina includes anomaly detection that flags suspicious patterns in documents, such as inconsistencies between totals and line items. This helps identify potential fraud or data entry errors before they enter your systems.

Invictus delivers the highest accuracy and is ideal for complex or multi-language documents — it costs the most credits. Praetorian offers a balanced mix of accuracy and speed and is the recommended default for most use cases. Velox is optimized for speed and cost efficiency, ideal for high-volume processing of straightforward documents.

Start with Praetorian for most use cases. Switch to Invictus for complex documents where maximum accuracy matters, or use Velox when processing large volumes of simpler documents where speed and cost savings are priorities. All three models are available on every plan, including the free trial.

These are optional processing enhancements you can enable per extraction. Thinking mode enables deeper AI reasoning for complex layouts and ambiguous content. Evaluation mode adds a validation step that checks extraction quality against the source document. Correction mode applies automated error correction. Each adds processing time and credit cost but can significantly improve results on difficult documents.

Templates let you define custom extraction schemas for any document type beyond invoices. You specify the fields and tables you want to extract — supporting text, numbers, booleans, arrays, and tabular data — and Gemina uses AI to pull that structured data from your documents.

Upload a sample document in the console, and Gemina's AI will automatically suggest an extraction schema based on the document's structure. You can review, edit, and customize the suggested fields and tables before saving. Templates can also be created and managed via the API.

Template limits vary by plan: Bronze includes 1 template, Silver includes 5, and Gold includes 10. Enterprise plans offer unlimited templates. You can activate and freeze templates to manage your allocation.

Gemina provides a RESTful API with full OpenAPI documentation. Authenticate with your API key via the X-API-Key header, upload documents to the upload endpoint, and retrieve structured JSON results. The API documentation page includes complete code examples for all supported languages.

Code examples and SDK guides are available for Python, Node.js, Java, C#, and PHP. Each includes samples for common operations like uploading documents, retrieving results, and handling webhooks.

Yes. Webhooks are available on plans that include webhook support. Configure endpoints in the console to receive real-time notifications when document processing completes, eliminating the need to poll for results.

Yes. The API supports batch upload endpoints for high-volume processing. Documents are processed asynchronously, and you can retrieve results via polling or webhook notifications.

The API returns structured JSON with extracted field values, confidence scores, and optional field coordinates. Each extraction includes metadata such as processing status, model used, and any validation warnings.

Gemina uses AES-256 encryption at rest and TLS 1.3 encryption in transit — the same standards used by financial institutions. Encryption keys are managed through hardware security modules (HSMs). Infrastructure includes network isolation, automated security patching, and 24/7 threat monitoring.

Yes. Gemina is fully compliant with GDPR and CCPA. We support data subject access requests, right to erasure, data portability, and the right to opt out. We never sell personal information.

Yes. Gemina offers data residency options across multiple regions including Israel, Europe, United States, and Asia. You select your preferred region in the console settings, and all document storage and processing occurs within that region.

No. Gemina never uses your documents or extracted data to train AI models. Your data is processed solely for extraction purposes and is yours alone.

Retention periods range from 1 day to 1 year, depending on your plan. You can configure automatic data purging in your account settings. Documents and extracted data are permanently deleted after the retention period expires.

Yes. You can manually purge individual documents and extraction results at any time from the console or via the API, regardless of your configured retention period. Account deletion is also available from the Settings page.

Support varies by plan: Bronze includes email support, Silver includes personal support, and Gold includes dedicated support. Enterprise plans include a dedicated account manager with SLA guarantees.

Create, view, and revoke API keys from the API Keys section in the console. Keys can be named for easy identification. When you create a new key, the full value is shown once — make sure to copy it. Revoked keys stop working immediately.

Yes. The console includes comprehensive reporting: extraction history with filtering, accuracy metrics, latency tracking, model comparisons, cost breakdowns, and field-level analytics. Reports can be filtered by date range, API key, extraction type, and model.

Cancel your subscription at any time from the Subscription page in the console. Your plan remains active until the end of the current billing period, and you can resubscribe at any time.
