Gemina has provided us with a great way to streamline invoice processing and improve the overall user experience. With nearly perfect accuracy, it saves our users time and effort, and increases customer satisfaction.
Rami GabaiCTO, Morning
I was a little skeptical at first, but it didn't take me long to realize that Gemina delivered on its promise. We see high success rates and quick response times that make our users very happy. The results were way beyond anything that I could have expected.
Eliran ZamirCEO, Webenefit
We use Gemina as an Invoice OCR for our accounting service. This tool solves the need for time-consuming data entry for our users, and helps to increase satisfaction levels. Integration was easy and most importantly - fast, thanks to the Gemina team 24/7 support. Kudos!

What you get back

One document. Three ways to use it.

Upload once. Everything below comes from the same document, through the same API.

Extract

Get every field as typed JSON.
Headers, line items, and your own custom schemas.

An invoice converted into structured vendor, total, and date fields, each marked with high confidence

Every field carries its own confidence.

Search & total

Find any document by meaning or by field.
Get exact totals, computed in the database.

A search for Acme Supply returning three matching invoices and an exact total of $28,451.67 USD across 127 documents

Ask for a total without naming a currency and the server groups them apart rather than adding them up — and says so.

Ask

Your users ask questions in plain language.
Answers come back grounded, with citations.

A full Document Assistant chat: an exact $900.24 total across two invoices with source-document citation chips, followed by a categorized expense breakdown

Every answer links back to the documents it came from.

The difference

More than an OCR. Here's the difference.

Everyone knows what an OCR does.
Here is what you still have to build afterwards — and what you don't.

The document is only the beginning. What matters is everything your product can do with it next.

A plain OCR

You get text. That's it.

Add the review step. Don't build it.

Embed the source document beside editable headers, line items or template fields. Corrections return to Gemina as an audited payload your existing integration already understands.

  • Focus reviewers on uncertain fields
  • Retrieve the verified result in the same shape

Custom Template Builder Interface
Smart Templates

Your schema, built by AI.

Upload a document and get an extraction template automatically.
Review it, edit fields, or customize the schema to match your needs.

  • AI analyzes your document and suggests extraction fields
  • Add, remove, or rename fields — full control over the schema
  • Start extracting in minutes
  • Use the template ID in API calls for consistent results
How templates work
For platforms & SaaS

Put document chat inside your product.

A React component and scoped session tokens.
Your users ask; your API key never reaches the browser.

13 MCP tools: extract, tag, search, aggregate, index.
One hosted server. Discovery built in.

Tag, rename and enrich any PDF or image.

Typed extraction, results, history and feedback.

Document Intelligence

Search the collection, compute totals, index a document.

Why the numbers are right

The database does the math, not the model.

Totals are computed, never estimated

Sums, averages and counts run as database queries over your extracted fields.

Currency and units are never mixed

Ask for a total across currencies and the server groups them apart rather than adding them up.

When data is missing, Gemina says so

Low-confidence fields are flagged for review. The response tells you when a number would undercount. It never guesses.
